Tactical Errors 17
Chess is a game of bad moves. It is, in fact, the game that most
depends on error. No game has a greater variety of ways of going
wrong or gives you as many opportunities— dozens on every move.
Other games depend heavily on chance or on the mastery of
some relatively limited skills. But a chess game is decided by the
failings of one of the players.
Yet we refuse to recognize this. We like to think the game is
a battle between good moves and better moves. When we win,
we tell ourselves— and anyone who will listen— that the critical
difference was our fine maneuvering, our positional cunning, or
our tactical ingenuity. When we lose, well, it was a stupid mis
take— as if errors were an aberration, an extraordinary accident.
Mistakes can only be messy, ugly, and disruptive, we say.
Regardless of our own success, we like to think a chess game
should be won, not lost. (W e thereby ignore that most vital skill,
the ability to exploit enemy mistakes.) We try to elevate the
game to some level it can never achieve— at least not while it's
being played by humans.
The masters know better. They know that a well-played game
is not an error-free game. There are errors of varying magnitudes,
and each game is sure to hold some small mistakes. “Chess is the
struggle against error,” said Johannes Zukertort, one of the great
est players of the last century. Victory belongs to the player who
struggles best— not just against an opponent, but against himself.
And the fact is that most games, even at the grandmaster level,

What Is a MistakeP
“Where did I make my mistake?” asked the loser, an Australian
master. “I didn't know what to say,” said the winner, a Russian
grandmaster. There wasn’t one move you could pin the blame on.
Yet by the 14th move White was already in grave trouble.

lowed by N-Q5 and R-R7) only by giving up more material.
White eventually won.
It’s safe to say that Black lost the game early on, around moves
11 to 13. We may be able to inck out a single losing move. But
Catalog of Chess Mistakes
there are so many reasons for error and so many ways to err that
we can only guess at the nature of the decisive mistake.
For example, we might say Black lost because of a faulty atti
tude. He could have equalized chances with the safe 1 1 . .. . B—K3
but sought the advantage instead: h e tried for too much. Or he
may have been overconfident because of his faith in book knowl
edge. Only a few months before this game was played, another
game (Alapin-Leonhardt, Pistyan 1912) followed the same moves
but Black obtained the advantage— 13, BxN? R -R l! 14. Q -Q l
(or 14. BxQ RxRch 15. K-Q2 RxR with material loss) 14.. . . RxR
15. QxR NxBI 16. PxN PxB 17. P-N4 P-B3.
Or we could blame Black’s downfall on an oversight, a failure
to consider the queen sacrifice (13. NxN!). The term “oversight”
tends to be misleading. Nobody guesses every move his opponent
makes. At the master level players “overlook” their opponent’s
middlegame moves as much as 50 percent of the time. But most
of the time the failure to anticipate a move isn’t punished. Black
of course knew that 13. NxN was possible. His “oversight”— if it
was one— consisted of not evaluating the sacrifice sufficiently.
What he overlooked was not the move but its strength.
Perhaps Black did examine the sacrifice but miscalculated. He
could have erred by overlooking White’s order o f moves. (For
example, he may have counted on 14. N -B6 and satisfied himself
that Black was okay after 14. . . . R -R l! 15. KxB Q-Q2.)
Or he may have assumed incorrectly. (He may have played 12.
. . . N-Q5 thinking that after the queen sacrifice he could meet
14. BxN with 14. . . . Q-Q2 15. NxB P~B3 16. N-K7ch K -R l 17.
B-KR4 P-N4! 18. BxNP P-B3. But after 14. BxN he may have
suddenly realized that 14. . . . Q-Q2 could be met by 15. N-B5!;
e.g., 15. . . . B-R 4 16. QN-K7ch K -R l 17. BxP mate or 15. . . .
K R -K 1 16. KxB).
Or Black may have gone wrong in his calculations by missing
White’s quiet m ove, 15. KxB. That recapture doesn’t seem aggres
sive enough until you see that 15. . . . RxR 16. RxR PxB 17. N -B6
traps Black’s queen (17. . . . Q-Q2 18. NxPch). Black may have
underestimated a move, 15. KxB, that doesn’t attack anything
and defends very little— yet it wins.
Finally, we could say the real error came earlier, at move 11,
when Black rushed into playing an apparently good move when
The Game of Mistakes 7
there was an even better move. His error had less to do with
tactics or calculation than with the practical process of choosing
a move. (With 11. . . . P -R 3 Black forces a favorable exchange on
his KB3 since 12. B -R 4 takes the sting out of White’s attack; e.g.,
1 2 . .. . B-KN5! 13. N-Q5 P-N4!.)
Any one of these errors— or a combination of them— may have
been the culprit. Only the loser knew for sure.
Position a fte r 1 3 . . . . B -N 2
P osition a ft e r 2 5 . . . . N—R 2
So far White has made some minor strategic mistakes and has
earned a dangerous-looking but risky position. Black’s last move
prepares a powerful stroke in the center, . . . P—K41. Without
White’s kingside demonstration,. . . P-K 4 would be a major posi
tional concession, giving away the KB4 and Q4 squares to White
and making N-Q5! a winning idea. But under the new circum
stances, Black will be able to develop a grip on the black king-
side squares if he plays 26. . . . P-K4; e.g., 27. P-KB5 B-N4! 28.
N-B3 BxB 29. QxB N(Q)-B3 30. N-KB2 N-N4 or 27. Q~N3 PxP
28. BxBP N-K4 29. N-Q5 BxN 30. KPxB N~N4 (or 30. BPxB RxB
31. BxB P-QN4 followed by . . . N~~N4 or . . . B-N4).
But what else can White do? With 26. N-B3 he stops 26. . . .
P-K4 but allows 26. . . . BxN 27. BxB N(Q)-B3 winning a pawn.
He certainly doesn’t like that, but he doesn’t want to go on the
12 Catalog of Chess Mistakes
defensive after . . . P-K4. Faced with yet another choice, this time
between pessimistic alternatives, White makes another error:
he goes for broke.
26. P-K5?! PxP
27. P-KN5
Now with 27___ RPxP 28. BxNch! KxB 29. PxNP White has a
winning game (29. . . . B-K2 30. QxP). But his panic after 25. . . .
N~R2 has provoked a miscalculation.
2 7 . .. . KPxP!
White's choices from here on are either bad or worse. Recap
turing on KB4 is bad, but 28. PxB PxB 29. QxP QNxP (with a
deadly kingside attack coming up for Black) is worse.
28. BxBP B-K4
29. P-N6?! PxP
30. PxP BxB
31. PxNeh K -R l
32. K B1 R -B l
33. B-K4 N-K4!
Now Black’s threat of 34. . . . N-N5 or 34. . . . NxP ends the
contest quickly. White played 34. Q-N2, and after 34. . . . NxP
he resigned.
Taking Stock
Experience, as defined by Oscar Wilde, is what we call the
record of our past mistakes. Recognizing the inevitability of mis
takes is a good first step to dealing with them. The next step is
understanding what kind of mistakes we make. Only after that
can we take action to eliminate them.
You can begin by collecting as many of your past game scores
as you can find. (If you don’t record your games, start now.) Try
to locate a large number. Most people keep only their wins, not
realizing that you learn much more from your losses.
Ideally, you should have a balanced assortment of at least forty
games— some wins, more losses; some games with the White
pieces, some with Black. It doesn’t matter whether the games are
The Game of Mistakes 13
a rook after thinking only ten seconds, you may place the blame
on the poor attitude of carelessness or overconfidence. But if you
thought twenty minutes on the losing move, you will have to look
elsewhere.
By examining the responses to this checklist you can develop a
fairly accurate Error Profile of yourself. You’ll know whether you
are prone to blunder or lose more often through an accumulation
of minor errors. You may learn, further, that you are most liable
to blunder in the ending than the middlegame, or that you make
more of your serious errors in unfavorable positions (Despair or
Pessimism?) than in favorable ones. You’ll know when to be on
guard against your natural tendencies to err (Just as your posi
tion is improving? Just after a previous error?). You may find that
you made more errors in games you eventually won than in games
you lost.
Once you’ve developed this Error Profile you’ll know, in short,
what part of your game you need to work on away from the tour
nament hall and what to watch out for when you are at the
board. Self-awareness is the name of the game.

Black is the only player with serious winning chances, but vic
tory depends on White’s cooperation. Even if White were to lose
16 Catalog of Chess Mistakes
both of her pawns, she could still draw by keeping her king at
KR1, Then Black could never drive the king out of the corner or
promote her own pawn. A draw would be inevitable.
Yet White managed to lose. She lost, in fact, because she
looked only for a way of drawing the position. By doing so, she
completely overlooked a losing method.
1. K -R4 B-B3ch
2. K-R5
White is in a hurry to force a draw by liquidating the board’s
last pawns. She want to play P—KR4 and P-N5, disdaining the
sure draw to be had by keeping her king around KR1. What she’s
overlooked is cute. But she would have seen it had she asked,
“How can I lose?”
2----- B-N4!
3 . P-R4 K-B5!!
It’s too late to ask. After 4. PxB PxP White has obtained ma
terial equality but will lose the king-and-pawn endgame. Even if
she refuses to take the bishop, her king is too far away from
KR1 to stop Black’s KRP (4. K-N6 KxP 5. P-R 5 B-K 6 6. K~B6
KxP and .. . K-N5).
“The mistakes are there,” Savielly Tartakower said, “waiting
to be made.”
Tactical E rro rs
Allowing Mate
Of all the punishing strokes to overlook, the worst is mate. You
can lose a pawn or a piece and still continue the fight— perhaps
even win— depending on your opponent’s ability to play without
serious error. But when you walk into a mate, it’s time to set the
pieces up for the next game.

How can a good player overlook a mate? For the same reason
that he can permit a fork or a pin— or ruin his pawn structure or
lose a winning endgame: there is so much to look for in a chess
game that you can only focus on a limited number of considera
tions. In many cases a master will make a bad error, which loses
the game immediately, because he is trying to avoid the many
minor mistakes that might cost him the game in the long run.
In the diagram Black is intent on breaking through on tire
queenside where his strength is massed. After 1. PxP PxP Black
will be able to pile up on the vulnerable White QRP after 2. . . .
P-N5 and 3. . . . N-N2. If White does nothing about the queen-
side, Black will penetrate with 1. . . . PxP; e.g., 2. PxP R-N7 3.

Removal of Defender
When I was just beginning to learn the game, one thing always
struck me about the moves of more experienced players. During
the early stages of a game most of the pieces, White and Black,
were protected by friendly pieces.
This seemed astonishing at the time. In my early games it was
impossible to keep half my pieces safe from capture at any given
moment. I didn’t deliberately put my men on squares subject to
enemy attack. But inevitably they were captured through the
usual assortment of tactical ideas: skewers and forks and pins.
The only time my material was completely safe was when the
pieces were suffocating along the first and second ranks.
More experienced players know how to advance and keep their
pieces in mutual protection. It becomes so natural that Mikhail
Botvinnik surprised his colleagues when he praised his rival,
Tigran Petrosian, after losing the world championship to him.
Botvinnik could have cited the new champion’s positional depth
or endgame mastery or calculating ability. But what Botvinnik
cited above all was simpler: “Notice how his pieces are always
protected.”
In its basic form, this is a game of weaknesses. Each player has
a set of weaknesses to defend— his king, perhaps, as well as some
pawns, key squares, and pieces— and some targets of the same
nature to attack. Eventually there is a tactical breakthrough be

Double Attack

mally have weaknesses, the player with the most efficient and
coordinated force will be able to exploit its advantage tactically.
Faulty Tactics
Black’s last sequence is what we call a “little” combination,
although it takes a bit of hard calculation. One or two tactical
devices stand out, and die rest of it is “if he plays there, I play
there.” Masters make it look routine. Tactical play, however, is
a double-edged sword, no matter how familial- you are with forks,
skewers, and other tactical devices.
Another trap is thinking you are the only player who can use
tactics:

On the other hand, not all checks are good. In a typical game
of forty moves the opportunity to check arises more than fifty
times— sometimes more. But you rarely see more than ten checks
per game. Most of the available checks deserve the German name
wopatzerschach— “a check so bad that only a patzer would give
it.”

White must defend, and that means giving up the Exchange for

Now, after 17. . . . B—N2, it seems that his diagonal has finally

Mistakes with Pieces
Faulty Development
Development is better than riches. With your pieces developed
you can take middlegame risks and engage in long-term planning.
Without development, you have to worry about getting out of the
opening alive.
Yes, there are many opening systems in use that sacrifice de
velopment for strategic pawn moves or pawn-grabbing. But these
systems require extra care and may be intrinsically unsound even
in the hands of the best players.

White’s two bishops may have a future, but White must first do
something about Black’s excellently centralized queen. The sim
plest way of holding the two threatened White pawns (K5, QR2)

Mistakes with Pieces 69
W rong Rook
Another special case involves tire last pieces to be positioned
for the middlegame. The rooks don’t seem to do much until the
later portions of the contest Yet their placement has a lot to do
with planning and long-term strategy; misplacing them will, at
minimum, cost time.
When there are two open files and you have two rooks, it
usually doesn’t take much thought to determine where your
heavy pieces belong (one on each file or doubled on one file). But
when you have three files, one open file and two half-open files
(open only from your end), or some other situation, the choices
become harder. The basic rule is to use the rooks where they can
be most flexible.
Sometimes this requires considerable foresight. For example,
after 1. P-K4 P-QB4 2. N-KB3 P-Q3 3. P-Q4 PxP 4, NxP N-KB3
5. N-QB3 P-QR3 6. B -K 2 P-K4 7. N -N 3 B -K 2 8. 0 -0 0 -0 9.

P-QB3 B-N 4, it’s time for White to develop his rooks. Tire nor
mal squares are K1 and Ql. But on K1 the KR would not be
doing much— there isn’t likely to be much of an attack on the
White KP and not much chance of kingside attack with R-K3.

Position a fte r 1 6 .. . . P -K N 4
Black uses his KR excellently for both defense (on the second
rank in case of penetration at his QB2) and for attack (at KN2 to
support . . . P—N6). Had White correctly used his KR, not QR
on QB1, he could now play 4. PxP PxP 5. QR-N1 and occupy
QN6 shortly. This would take some of the sting out of Black’s
attack. Note that White’s KR is doing nothing on KB1, and it
would do little more on K1 or Ql.

Now Black has both . . . PxP and . . . P-N6 as line-opening

what would have helped was the vacancy of his KB1. If you put
White’s QR back on QR1 and move his KR to QB1 (as if he had
played 1. KR-QB1!), White could bring his king to safety with

of suffocation on the floor of their apartment. Splinters of glass are
found near the bodies and the carpet is wet. How did their death
come about?
Katharine Hepburn muses a bit, repeats “Never assume, eh?”
and reaches a deduction that would have made Sherlock Holmes
proud. Fred and Eloise are goldfish who died when the bowl in
which they were swimming tipped over and smashed on the floor.
Without water they could not breath.
You shouldn’t have assumed Fred and Eloise were humans.
But chess players have to make assumptions in order to calcu
late. You can’t progress from the first move of a combination to
your second move without some supposition about what the
enemy is doing in between.
Quiet moves overlooked and zwisclienzugs ignored are some
of the many cases of faulty assumption. Occasionally you can
look pretty silly because things didn’t happen the way you
assumed they would.

Overlooking Attack-Defense
Most calculations are by nature concentrated on forcing moves.
We make a capture, our opponent recaptures. We threaten, he
defends. In calculating this way we cant examine every choice
at his disposal. Only the computers can do that— and they spend
minutes to do it even at their incredible rate of considering
variations.
When calculating out these sequences we sometimes fall into
a psychological hap. We feel that we are the aggressor, the one
who sets the tempo of play. But the trap is sprung when the
enemy responds with what well call the "Attack-Defense” move.
It’s a move we overlook or underestimate, and it has great impact
because it wrests the initiative from our hands. The opponent not
only meets our threat but also makes one of his own. Our pieces,
coordinated for attack, may be unprepared for the sudden role
of defense.
Here, after 19. PxP PxP 20. BxKP, Black would have his choice
between winning the Exchange (20. . . . BxB 21. RxB Q-N4ch
22. K-moves N-N6ch) or playing for mate (20. . . . N-R5).
White’s pieces are disastrously tangled on the kingside because

controls the open queenside lines, so he will be able to make use
of that pawn in the middlegame. There are many consolidating

Clearly Black cannot take the other bishop (13. . . . BxB 14.

14. BxB QxB 15. N-Q2 and come to the conclusion that Black’s
position was acceptable after 15. . . . N -B3 because the weak
ness of his QBP is offset by White’s weaknesses on the kingside
and at his Q3.
14. KR-Q1!
This is the shot Black overlooked or underestimated. White
will meet 14. . . . PxB or 14. . . . BxB with 15. RxN, which gains
time for a second capture by attacking the Black queen. Black
may have seen this far but assumed that 14. KR-Q1 could be

could anticipate all this with 18. . . . P~B4, but then 19. P-N5!
followed by P-QR4, Q-R2, KR-N1, and P-R5 gives White an
other good plan.
Black could also recapture on K5 with his BP, although this

Mistaken Sequence
Finally, there are mistakes to be made with the order of moves.
You may see all the tactical ideas in a combinational position,
but if you don’t get them in the right order, the combination falls
flat.
relieve the pressure and protect his KN2 with . . . P-N3L White,
therefore, looks for a method of exploiting the moment. He can’t
force Black’s KB away, but he can do something about the queen.
1. N-B6? Q-B2!
The flaw in White’s combination was his failure to see 2. QxN
QxR!, which removes his queen’s defender. The idea of driving
off the queen and capturing on KB6 was a good one, but once
again the idea was improperly presented. With 1. B-N5! Black
would have been quite lost (1. . . . K -R l 2. BxN PxB and now 3.
N-B6!; or 1___ K -R l 2. BxN QxB 3. QxQ PxQ 4. NxP mate).
The new position on the board presents a second crisis for
White. He could retreat the attacked knight to K5 or look for a
consistent followup to his attack. White’s last move, as faulty as
it is, creates new tactical possibilities involving R-K5 and R(K)-
KN5 or BxP. But again there is a good order of ideas and a bad
one.
2. R-K5?
Though this threatens both 3. BxP BxB 4. R(K)-N5 and 3. QxN
(now that Black can’t take the rook on KN6 with his queen), it is
far inferior to the right order: 2. BxP! BxB 3. R-K5 K -B l! 4,
R(K)—N5 with chances.
2----- P-N3!
Now we see that 2. R-K5 wasn’t forceful enough. The attack
on KN7 is all over, and Black’s counterattack soon proved deci
sive: 3. BxB RxB 4. QxN QxN 5. P -R 4 KR-Q1 6. R -K l R-Q41
7. R -K B3 Q-Q 2 8. P-N3 R-QB1.
Positional E rro rs
Often a player will explain his choice between two lines of play
with: “I decided to make the game tactical because I was get
ting a bad game positionally,” or “I wanted to play that move but
it just looked too antipositional,” or “Tactically this was a good
idea, but I was afraid that it would compromise my position.”
These common post-mortem comments suggest there are two
separate kinds of moves, positional and tactical.
In fact, the distinction is much more subtle. A good game in
positional terms will create its own tactical ideas. A poor game
positionally may have some short-term tactical benefits but won’t
be able to generate the vital threats that are needed to win in
the long run against a worthy opponent.
A few years ago I won a pleasing game, which was then pub
lished in a number of chess magazines. What surprised me was
the reaction of friends who played it over. They saw the queen
sacrifice that ended the game and congratulated me for outplay
ing my opponent tactically. In truth, there was only one tactical
phase of the game, the very last move.
After 34. NxQ RxRch 35. K -R2 B-K4ch Black mates in two
more moves. It is a pretty finish. But the game had been decided
from a positional point of view by move 18 because of White’s
repeated positional concessions. Let’s look at the critical errors.
8 P-QR4: White sought to stop 8. . . . P-QN4 followed by 9.
. . . PxP, a flanking thrust that would have given Black a majority
of pawns in the center. But after 8. P-QR4? P-QR4! Black had
tricked his opponent into creating a hole at White’s QN4. White
then had no pawns that control this square and this was a sig
nificant concession. Why? Because the nature of the center pawn
structure often requires White to drum up queenside play with
P-QN4-5 or P-QN4 and P-QB5. After 8. P-QR4? P-QR4! Black
can meet a subsequent P-QN4 with . . . RPxP, isolating White’s
QRP and creating a new semi-hole, at White’s QB5. White’s
queenside play is dead.
12. P-Q5 and 13. N -K l: After 11___ Q~K2 White had to pro
tect his KP from the threat of 12. . . . PxP 13. NxP (13. QxP N—N5)
NxP. With 12. P-Q5, however, White created another hole at his
QB5, which Black might have been able to exploit later with . . .
N-B4. White also gave up all chance of opening the Q-file with
QPxKP after he advanced his QP. True, he could have continued
Positional Errors 103
13. QPxBP, but that would have granted Black excellent queen-
side play against White’s backward QNP along the QN-file. Note
that after 13. QPxBP White would have gotten a good positional
game with P-QN 4-5 (securing Q5 as an outpost square) if the
moves P-QR4/ . . . P-QR4 had not been played earlier. Thus,
small positional errors add up to big concessions.
14, P-KN4?: After Black closed the queenside permanently,
the only sector of the board to be opened was near the kings.
Black had a natural advantage there because . . . P-KB4 was
good for him, whereas P-KB4 would have been double-edged for
White (since after . . . KPxBP Black could have set up an excel
lent outpost on his vacant K4 square). For this reason White
played 14. P-KN4 with a view to establishing a solid bridge of
pawns on K4, KB3, KN4, and KR3. But since Black could play
. . . P-KR4 as well as . . . P—KB4, White’s natural inferiority on
the kingside had to be exposed. Again, had it not been for his
earlier queenside errors, White might have been able to ignore
the kingside and seize the initiative on the other side of the board.
17. KPxP? and 18. PxRP: This was positional surrender since
afterwards Black dominated the center and built up at will on
the kingside. After this White had little counterplay in the center
or on the queenside and could only await disaster on the KN-
and KR-files, Black’s positional edge made the final tactics
possible.
Positional errors, as demonstrated above, are crimes against
the pawn structure, the only static aspect of chess. Since pawns
cannot move backwards, their advances have a great bearing on
the performance of the other pieces— a bearing that is difficult
to alter at a later stage. Pawn moves turn bishops from good
pieces into spectators, weaken king positions, open dangerous
lines for enemy pieces, create permanent weaknesses, and estab
lish endgame advantages.
It can’t be denied that sometimes a move is tactically good but
positionally bad. Whether it is ultimately a good move or a bad
one depends on the size and immediacy of the tactical advan
tages it confers. If it creates insurmountable threats, the move is
good. But the attack may fail and the positional defects prove
costly in the long run.

Bad Bishops
Since the two players begin with two bishops each, any pawn
move will affect one pair of bishops. But if bishops are traded
off, for each other or for knights, the advance of pawns to
squares controlled by the remaining bishops can be of major
significance. If both sides have white-square bishops, for example,
you should consider very carefully any advance that puts a pawn
on a white square. Such an advance is doubly disadvantageous
since it limits the scope of your bishop and creates a target for
the enemy bishop.
Here is stark example of this common clerical crime.
Creating Holes
Another reason that 14. P-K B4 is bad in the game above is
that it abandons pawn control of White’s K4. After that pawn
Positional Errors 107
move Black could occupy the K5 square with a rook and pressure
White into more weaknesses. He had a valuable hole for his
pieces.
There are any number of excuses for creating pawn holes. “It
was the only way to make my pieces active,” or “I couldn’t per
mit him to occupy the other square so I gave him this one,” and
so on. Sometimes you get drawn into a very bad, hole-ruined
position by making natural-looking moves. This is what hap
pened to Black below:

Ruy Lopez opening. Whether you play this opening or not, you
can appreciate the nature of the middlegame battle. With a some
what closed center Black’s slight edge in development isn’t sig
nificant. White parries Black's threats (17. . . . N-Z37? 18. R -B l)
and is ready to take over the initiative after N-N3, P-QR3, B-Q3,
and QR-B1.
All of this suggests that Black should open some lines for his
pieces. But this would be bad thinking. His pieces are not par
ticularly well centralized and would not profit from an opening

You can open lines for the enemy without offering exchanges
of pawns. The advance of a pawn will in itself close certain lines
and open others. In the following example we see Black with a
substantial positional advantage because of his superior minor
pieces, his control of the open QR-file, and the possible weakness
of White’s QP. But there is no clear way for Black to enlarge his
edge.

Neglect of Center
Before you begin planning you must be secure in the center.
This is the bare minimum of strategic decision-making.
You don’t need a model center, with two or three healthy
pawns on center squares. You may not need any pawns at all in
the middle of the board. What you need is assurance that your
opponent won’t be able to dominate the center. If the center is
closed by a mass of immobile pawns you are free to indulge in
the lengthiest of maneuvers on the wings (such as on p. 178). But
if the center is partially open and you have little control over its
squares, there is no time for wing strategies.
After the opening moves 1. P-Q4 N-KB3 2. P-QB4 P-KN3 3.
N-QB3 B -N 2 4. P-K4 P-Q3 5. N-B3 0 -0 6. B-B4, White has an
ostensible superiority in the center because he has three pawns
there whereas Black has none. But Black has the potential to
fight back in the center. For example, with 6. . . . B-N5 7. B-K2
N-B3 he is ready to neutralize the center with 8. . . . BxN 9. BxB
P-K4!.
If Black neglects the center, however, he turns the most valu
able real estate on the board over to White; e.g., 6. . . . P-KR3?

“After all,” White might say, “I can kick the Black rook back
wards and then choose between attack on the weakened king-
side and advance on the queenside with P-B5.”
“Not at all,” Black would reply. “Your pieces are inferior to
mine in terms of center control, and your wing attacks therefore
won’t work. I can put my bishop on B4 and queen on B3. What
can your pieces do?”
Black is right. The position favors him slightly, whether in the
middlegame or ending (e.g., 14. B-Q 3 R -K l 15. Q~B3 Q -B3 16.

Onesidedness
Having found a good plan on the right side you can still go
wrong by concentrating entirely on it to the detriment of the
other sectors of the board. There is a dangerous tendency to
130 Catalog of Chess Mistakes
mentally divide the board into “my side” and “his side,” ignoring
developments on the opposite wing while you devote your ener
gies to following through with the plan on “your” side.
This is the starting point for strategy since both players are
nearly finished with their development. White prefers to play on
the queenside, where he has a numerical majority of pawns and
an effective pawn break with P-QB5. Black's choice is more
difficult If he continues routinely (14. , . . N—B3 15. P—QN4
B-Q2 16. Q—N3 K—R1 17. QR-B1 R -B l) White will accomplish
his goal (P-B5) before Black can even hint at counterplay.
Just from hearing a description of White’s strategy you should
know that Black’s interests are likely to lie in the center and on
the kingside. He could generate some activity with 14. . . . B-N4!,
for example. That would seek an exchange of Black’s bad bishop
— a positional idea— and also advance a strategic goal (by gain
ing space on the kingside, by weakening K6, and by permitting
Black to seize the initiative on the queenside with . . . Q-N3 once
the bishops are exchanged). Of course, White can— and should
— retreat the bishop, 15. B-KB2, but Black would have gained
space for himself with 14. . . . B-N4. He can seek kingside weak
nesses for a later attack (15. . . . B -R 5 16. P-KN3 B--N4) or pre
pare for play in the center with the pawn sacrifice of 15. . . .
P-K5 16. PxP P-B5! followed by . . . N-K4 and . . . B-N 5 or
. . . P-B6.

Black has chosen a bad plan. He is right to look toward the

order to threaten 17. . . . R -B 3 and 18.. .. R-R3.
His decision was prompted by a simple practical concern: he
didn’t see how W rite could possibly defend his kingside now.
White cannot cover his KR2 sufficiently (17. K -R l R -B3 18.

Strategic Errors 133
Unjustified Attack
Black went in for a poor attack in this last example knowing
that it was suspicious but not being able to foresee how White
could defend himself. Most decisions to attack are made with
different attitudes. Players decide to attack— be it on the kingside
or queenside or in the center— when they feel their position war
rants it. An experienced player will go further: “I didn’t even like
the idea of attacking. I wanted to play a quiet game today. But
the position dem anded that I attack.”
When an attack is unjustified it is usually because of (a) inade
quate development, (b) the availability of enemy counterattack,
and (c) the absence of vulnerable targets. We’ve touched on the
first two before. The last item is tricky and goes to the heart of
134 Catalog of Chess Mistakes
Black’s king looks a trifle awkward but his pieces are otherwise
well posted. What should White do? He can complete his devel
opment with B-K3 and R -Q l and await events. But Black would
then be able to call the tune with . . . P-QR4 and . . . P—N5.
White could organize his men for play in the center (Q-K2,
R-Q3, B-K3, and QR-Q1). This would be a better idea than
waiting but is still relatively passive. There simply isn’t any
aggressive play in the center since all the possible targets (Q6,
K5, K6) are well protected.
So White must look for a target or begin to think about going
on the defensive. An ideal way of meeting Black’s . . . P-QN5
plan is 1. P-QN4I. Although this concedes the fine QB4 square
to Black’s pieces, it threatens a queenside attack of White’s own
with P-QR4.
1. P-KR4?
But there wasn’t enough reason for continuing a kingside
attack. You might blame what now happens on the absence of
White’s QR and QB from the kingside. Or you could say White’s
collapse is due to Black’s rapid seizure of open lines for counter
play. But the main reason for the result of this game is White’s
misjudgment of the Black king’s status. The king is actually quite

The first task, naturally, is to identify what the enemy plan is.

Reducing T ension
When pieces come into conflict and when pawn exchanges are
possible, a degree of tension exists on the board. This tension
may benefit both players or only one of them, But once estab
lished it won’t easily go away. To reduce tension by liquidating
the pieces that can capture one another and/or by trading off the
pawns that are in contact, you eliminate some of your options
and may do away with whatever counterplay is available.
Take the following position, reached by mutually aggressive
opening play (1. P-K4 P-QB4 2. N-QB3 N-QB3 3. P-KN3
P-KN3 4. B-N 2 B-N 2 5. N-R3 P-K3 6. 0 -0 KN-K2 7. P-Q3 0-0
8. B -K 3 P-N3 9. Q-Q2 P -Q 4 10. B-R6).
Strategic Errors 139
10.... P-Q5!
Black reduces the central tension with an advance rather than
a capture, but the effect is similar. Prompted by the threat of a
White attack on his king, Black establishes a solid center that
will benefit his white-squared bishop. He can assume White will
trade off Black’s bad KB. Then if Black survives the kingside
attack, he will have a good game positionally.
11. BxB KxB
12. N-K2 P-K4
13. P-KB4
White needs an open line for Ills attack and so creates a new
point of pawn tension. The advance of his KBP gives him two
middlegame options— opening up the KB-file, presumably after
R -B 2 and QR-KB1 with BPxKP, and staging an overall pawn
march with P-B5. In the current position he may be intending
an immediate 14. P—B5 so that on 14. . . . P-B3 (14. . . . B—N2??

1 3 .... P-B3
14. PxP??
But this is very bad. White gives up the option of P-KB5 and
makes an attack along the KB-file doubtful because of Black’s
140 Catalog of Chess Mistakes
ability now to cover every key square (KB3 and KB2 chiefly) that
may be attacked. The reduction in tension is mysterious. White
had no reason to fear an exchange by Black (. . . KPxBP) because
White would then recapture with his KNP and have all sorts

1 4 . .. . NxP
Black gets an excellent square for his knight and prepares to
find another with 15. . . . N—N5 and 16. . , . N-K6. This threat
gives Black time to keep White from playing N-KB4 and thereby
reduces White to his only remaining middlegame plan— opening
up the queenside with P-QN4. That this is insufficient is demon

Stifling Counterplay
This leads to the problems of counterplay. When your oppo
nent has the initiative, you must find counterplay or doom your
self to passivity and waiting tactics. While passivity is not always
an error, it deprives you of the activity you need to worry an
opponent. Eventually he will find a winning plan and a crucial
breakthrough— if you don’t distract him with counteiplay.
The key errors involving counteiplay are (1) shutting off your
own, (2) failing to stop the enemy’s, and (3) trying to contain
counteiplay that can’t be contained. Here is a characteristic exam
ple of a misplayed middlegame featuring counterplay errors.
Black correctly sees his best chance for piece activity on the
kingside. But since White hasn't castled yet there is nothing to
attack. So it is time to take stock of the various paths. One is to
press on with kingside play, 10. . . . P-B5, and this is what Black
selected. A better idea is to preserve the kingside options with
10. . . . N(2)-B3, possibly followed by . . . N-R4^B5. The third
option is restraint on the queenside, the area White is most likely
to attack. 10. . . . P -B 4 is a good idea since it makes P-QN4 more
difficult for White to achieve, stops P-QB5 permanently, and
gives Black his own queenside chances with . . . P-QR3 and . . .
P-QN4. Finally, there is the trick of 10. . . . B-R3, a positional
move (intending to trade off the bad bishop) based on tactics (11.
BxB Q-R5ch and 12.. . . QxB).
1 0 . .. . P-B5?
Black commits himself to one specific kingside plan, the ad
vance of his kingside pawns with . . . P-KN4-5, possibly sup
ported by . . . P-KR4. Here it is too slow because there is nothing
yet to attack, Had he preserved his options— and counteiplay—
with 10. . . . QN-B3 he could meet 11. 0-0 with a now appro
priate 11___ P-B5 (12. B -B 2 P-KN4 13. R -B l R -B2 14. P-QN4
B - B l 15. P-B5 R-N2 16. N-B4 P-N5!).
11. B -B 2 P-QR4
Black suddenly turns to the queenside to stop White’s coun
terplay. He has probably realized by now that his kingside assault
was premature; e.g., 11. . . . P-KN4 12. P-KN4 P-KR4 13. PxP
N(2)-B3 14. P-KR4 or 12. . . . PxP e.p. 13. PxP N(2)~B3 14.
P-KN4 followed by N-KB1-N3-B51.
12. P-QR3 N (l)-B 3
13. P-QN4 P-N3?
Here’s another error involving counterplay. Black wants to stop
P-QB5, the pawn break critical to White’s queenside strategy.
But it is easy to see that White will be able to outgun Black for
control of the key square since White can prepare P-B5 with
N-N3 and R-QB1 whereas Black can only direct one more piece
(. . . Q-K2) against it.
144 Catalog of Chess Mistakes
But 13. . . . P-QN3 is worse than futile. It ensures that the in
evitable P—B5 will open two queenside files rather than just one
because of the added pawn tension.

Poor Timing
Chess is as much a matter of timing as it is of logic, calcula
tion, or imagination. You might conclude that N-B5 is a winning
idea in a position. But that judgment may apply only to that
position now. A minute ago the position was slightly different,
and then N-B5 could have been a losing move. And it may be a
losing move again at a later point in the game.
Haste is as much a crime as slowness, especially when mak
ing a substantial change in the status of the game. When you are
about to win material or exchange queens or make a dynamic
pawn break, it’s worth a minute’s thought to determine whether
there is any rush. If your opponent can’t do anything but shift a
knight back and forth "on the other side of the board, your game
could afford an extra tempo of preparation. Your threat (or cap
ture or pawn-break or material gain) won’t run away.

The key element is the immediacy of threats. If you have time
to take precautions, by all means take them. If the position is
relatively quiet, if it is more “positional” than “tactical,” if there
are no tactical flashpoints between the players’, you can afford
to be cautious. But if the position is on the verge of becoming
sharp, each tempo takes on extra value.
Position a fte r 9 . . . . B - K 2
You couldn't say the game has been sharply played or tactical
so far. It’s still very early in the game. But both sides are begin
ning to create threats. Black, for example, has the idea of . . .
P-N 4-5 to win the White KP or push enemy pieces backward in
defense of the pawn. He also has prospects of playing . . . P-R3!
so that the bishop cannot retreat to KR4 (. . . NxKPl) or KB4
(. . . P-K4) and must go to K3 where it will be exchanged off by
. . . N-N5.

his queen White also prepares to answer 10. . . . 0-0 with 11.
N-Q5! (11. . . . QxQ 12. NxBch and 13. RxQ). White might also
select 11. Q R -K l or 11. KR-K1 with tactical play in mind.
10. P-QR3?
Although this meets the threat of . . . P-N4r-N5, it wasn’t im
mediately necessary (10. Q R -Q l P-N4 11. N-B6!). The move
misuses the natural initiative White gets by making the first
move of the game.
1 0 . .. . P-R3!
Now, since White cannot retreat to KR4 (11. B—R4 NxP 12.

P-QN4.
Having made one slightly wasteful and overcautious move in
the opening, White now obtains a clearly inferior position by
making a hasty move. Here he sees that Black cannot play 12. . . .
N-B5 because of 13. QNxP! PxN 14. NxNP Q-B3 15. BxN. There
fore, White decides to take advantage of the placement of Black’s
centralized knight with 14. P-B4? instead of preparing it with 15.
P-R3. The difference is 14. . . . N(4)-N5, a dangerous move be
cause it forces the exchange of the bishop that now protects
White on the weakened black squares. (White can’t preserve the
bishop: 15. B-Q 2 Q-R2 16. Q-Q3 P-K4!).
The absence of protection on the black squares ultimately costs
White the game (15 P-R3 NxB 16. QxN 0-0 17. Q R -K l P-K4!

that brought him most of the way to defeat.
Passivity
Passivity, the practice of sitting on a position and waiting for
something to happen, is justified only when you are content to
draw and are worried about losing if you try to play forcefully.
148 Catalog of Chess Mistakes
Let’s use this rule on the position above. White has a clear
advantage in operating space but no obvious weaknesses to ex
ploit. Given enough time White can prepare for a breakthrough
in the center (doubling rooks on the Q-file and P-Q5) or on the
queenside (doubling rooks on the QN-file followed by N -Q 2-
K4—B3 in preparation for P-QR4 and P-N5).
Black can choose between a waiting game, mixed with minor
harassment of White’s pieces, or some sort of countereffort. While
a waiting game isn’t necessarily fatal, here it is inferior since
Black can get a good game with . . . P-QR4. For example, 1. . . .
P-QR4 immediately would either force White into a premature
advance—2. PxP QxP(4) 3. KR-N1 P-N3 or 2. P~N5? QxBP—
or a loss of the initiative— 2. KR-N1 R -R l threatening 3. . . .

the answer will probably be something like: “Well, because after

While each game is different in a tactical sense, some players

are addicted to a damaging state of mind when they get to a

You could say simply that Black lost because he failed to make
the required number of moves in his alloted time. Or you could
point out strategic errors (failing to restrain White with 6. . . .
P-QR4 or 11. . . . P-KR4) or tactical mistakes (walking into a
pin after 18. . . . B-Q2, failing to liquidate die tension with 20.
. . . NxP). But one can’t avoid the feeling that Black lost because
he never took the game seriously.
How can you worry about a game in which your opponent’s
first moves are 1. P-KB3, 2. K-B2, 3. P~~K3, and 4. P-KR4? One
can readily imagine Black’s self-assurance and his confidence that
his position would win by itself. Yet White’s moves, while weak
ening, are very difficult to exploit when the center remains closed.
(The first pawn to leave the board is the QP Black lost at move
21!) Of course, White never stood well in the opening stages of
the game. But Black never appreciated that his opponent still
had to be beaten.
This fatal sense of security is one of several dangerous errors
of attitude. Few players are objective enough to realize that the

Change of Fortunes
Chessplayers like to think their better games have a consistent
or singleminded “flow”: there are no sharp changes in the initia
tive. The player on the attack tends to remain that way for most
of the struggle.
But most games don’t have this “flow.” The advantage or
initiative changes hands once, twice, or more. When the status
quo is upset like this, both players must reevaluate their prospects
and alter their attitudes to keep in tune with the position.

danger he is in.

Letting Down
A similar change in attitude often occurs during a hard-fought
skirmish. After several moves requiring exact calculation, bold
ness, and imagination, the tension is eased. The new position
may require a different style of play— defensive rather than ag
gressive, or technical rather than speculative.
The drama is temporarily over at this point, but difficult moves
remain to be found. The cardinal error is to relax. Relaxing is
fine if your opponent is reduced to total passivity. But such posi
tions rarely occur. You must remain alert.

“Believing Him.”
A virtual prerequisite to effective calculation is a degree of
confidence in your own ability. Say you count out a sequence
and come to the conclusion that the final position is in your favor.
You can still undo all this mental effort by second-guessing your
self and playing a different line because you don’t trust your own
mind. Even the most hard-headed of players are guilty of this
fault from time to time.
But there is something worse than excessively questioning your
own play— not questioning your opponent’s. “Nobody bluffs in
chess,” you might assume. “Therefore, there must be a reason for
that last move of his. It looks bad, but he mast have something
there.” So you end up believing him and disdaining the effort to
refute his last move. (Usually you find out painfully in the post
mortem analysis how wrong you were. “What would you have
done if I had played . . . ?” you ask, only to discover that his own
analysis was all wrong and that your line of play would have put
the game out of reach.)

Dogmatism
Most of the common errors played today can be described as
violations of basic principles. These principles, discovered by
trial and error and then formulated by the great masters at the
end of the last century, separate the haphazard chess of the 1870s
from the more purposeful plan of the 1970s. At least the players

Drawmindedness
To most beginning chessplayers, a draw is a relatively rare
result. Their games are usually decided by bad moves— often
very bad moves— which make losing inevitable for the guilty
party. But the improving player learns to reduce the frequency
of his outright blunders and discovers that sometimes, despite all
his ingenuity, good moves alone cannot force a victoiy. The
result is a draw. All winning chances are exhausted.
At the higher ranks of chess, the most common result of a game
is, in fact, a draw. The masters have a better idea of what it takes
to lose a game, and their avoidance of the losing errors keeps the
position within the “draw radius.”
But the player who is eager to draw is frequently surprised
at how difficult a split point is to achieve. This is because there
are few automatic methods of forcing a draw. One is to reduce
the board’s material to nothingness. Another is to check the
enemy king perpetually. But otheiwise you have to work hard to
draw.

With this cementing of the queenside, White has nearly com
pleted his pawn fortress. But as long as there is one possible
point of breakthrough, he is in trouble. That breakthrough will
come along the KR-file, and it is impossible for White to stop it.
For this reason, White should have retained the glimmer of
queenside counterplay contained in P-QR3 and P-N4.
This didn’t necessarily doom White— it only made his defensive
task unrelievedly tedious. The game proceeded with great ma
neuvering and preparation.

“Hallucination”
The most bizarre form of visual error occurs when you seem
ingly forget how the pieces move. This isn’t supposed to happen
to experienced players, you say? Only to beginners?
179
180 Catalog of Chess Mistakes
Such mistakes are relatively rare. But even the best players
occasionally make comparable errors in their mind when looking
a few moves ahead. Consider the misfortune of young Mikhail
Tal, several years before he became world champion.
Tal was already a strong player at the time and was playing
his first match against a master. He fended off a brutal attack in
one critical game and was ready to consolidate a material advan
tage into victory. But suddenly he calculated a beautiful winning
idea. Both kings came under attack and eveiy tempo was vital.
Then, Tal recalled, “I discovered that the whole point of my com
bination lay in the move Bishop (from KB8) to KN5.”
The move was, of course, impossible, and Tal lost. Somewhere
in his calculations he had “moved” the bishop mentally to KR6
or K7, permitting it to land on KN5 at the decisive moment.
These errors are the easiest to explain and hardest to anticipate
of all the blunders you can make. When you begin to play chess
you are concerned about the capabilities of the pieces, e.g., “Can
he take me if I play Q-B4?” But as you progress in playing abil

Pretty Moves
One of the great joys of chess is playing beautiful moves, moves
that put material en prise, defy general principles and logic, or
simply create remarkable positions. But there is a greater joy
formany players: winning.
You don’t have to forsake pretty moves to win, as many of
these games show. But the highest priority in choosing a move
must be its usefulness to you. Art in a museum doesn’t have to do
anything. But artistic chess'moves must pass a test of utility.

But most of the time we must blame ourselves for simply not

doesn’t expect to find more no matter how long he looks.
This is amply demonstrated by the following position from a

Here the game was agreed drawn. Black was happy until some
one pointed out 8. K—N4 Q-R7!, a move that wins immediately.
Black had calculated everything out with his grandmaster

What they didn’t see was the correct evaluation of the position.

Black had gone through with the formality of sealing his last

by 4. , . . B-N5 or 4. . . . R -N l) with 2. BxB RxQ 3. PxR in order
to win.
Black assumed that such a position would have been just as
hopeless as the one he resigned in. Black must lose his knight for
a pawn after 3. . . . N~B3 4. B~R7! (4. . . . NxB 5. P -N 8 -Q )
and play the rest of the game a piece behind. Yet the game is

But White never needed to work for the win. Black’s pre
mature surrender with 1. . . . N-B3, made the task academic.

There is no real reason for this. Of all the pawns to win, this
is the most dangerous because it opens up another attacking file

But one pawn is enough to play for a win.

sacrificing the positional soundness of your game to win ma
terial. Often this means grabbing a pawn unwisely. It is not
greed per se, since greed is usually a lust for material when you
don’t need any more than you already have. This error is rather
a matter of strategic desperation, as in the following:
1 .... P-N5?
2. N-Q5!
Errors with Material 207
L... R-K2?
True, this defends KB2 against 2. Q—R5 and saves the attacked
rook as well, but a deeper look into the position would have
convinced Black of the seriousness of his plight. He could have
squelched all immediate attacking threats against him with 1.
. . . RxN! 2. RxR NxP and retained good winning chances with
two pawns for the exchange.
2. Q-R5 P-R3
3. N-B5! RxRch
4. RxR PxN
5. R-K3
5.... B -B l
6. BxP! BxB
7. R-K8eh Resigns
1. R-K6?!
l . ... PxR
2. QxPch B-N2
3. N-K4 R-KB1
Black easily covers the threatened 4. NxNch which would be
met by 4. . . . RxN 5. BxR QxB keeping an extra piece. White can
now try to open more lines with 4. PxP, but after 4. . . . BxP 5.
NxNch RxN 8. Q-~K8ch Black defends easily with 8. . . . B -B l.
There is one other try, but Black’s extra material and natural
positional edge permit him to refute it with elegance:
4. P-N3 QxN!
And White resigned shortly after noticing that his queen would
be trapped with 5. . .. B -K l.
1.... NxB
2. N-R5ch K-R3
3. R-R3
3. QxR!
KxN
But Black has more than ample compensation if you remember
the original piece he captured (1. . . . NxB). Now, with two minor
pieces and a rook facing a disrupted White kingside, it turns out
that the White king is the most vulnerable. A queen counter
sacrifice ended the game abruptly.
5. QxP R-B6!
6. N-Q4 RxKRP
7. N-K2 N-B5
8. NxN BxN
9. K-N2 R-QB1!
White resigned since Black will mate with 10. . . . R -N lch 11.
KxR B - B l once the White queen leaves QB5.
