Day 35: Open Diagonals and Fianchetto
100% Positional Training Completed
Previously we have discussed the importance of possession of an open file, fighting for the file and penetrating it
with rooks or a queen. The diagonal is no different from the file, you also need to fight for it and control it with a
bishop or a queen. In this lesson we will learn about the importance of efficiently using diagonals to win games.
Open diagonals are a very important positional element of chess that should always be taken into account
when analyzing a position and coming up with a plan. Possession of an open diagonals gives a serious
positional edge that can be used to launch an attack on the king or maneuver the pieces on opposite side of
the board.
The strongest of the diagonals is typically considered to be the long diagonal, because it connects two sides
of the board and can be used to threaten the opponent’s castled king.
Let’s take a look at the position below. White controls the long a1-h8 diagonal. Taking into account that
black does not have a dark squared bishop to counter the treats he is vulnerable via the dark squares.

These two factors give white a stable positional edge. You should always remember to keep the bishop that
matches the color of your pieces. That means if you play white, the light squared bishop is more valuable for
you, assuming you plan to castle short. If you play black – it is the dark squared bishop that you should keep.
I want to mention a couple of important points about fianchetto pawn structure and bishops. Many players
nowadays choose to play dynamic openings involving fianchetto of one or even both bishops: King’s Indian
Defence, Catalan, Sicilian Dragon, and other so-called hyper-modern openings.
What is an advantage of having a fianchettoed bishops? The main idea behind most fienchettoes is to
activate the bishop at the flank by occupying the long diagonals, where the bishops are the strongest. The
hyper-modern opening approach favors delay in occupying the center with a plan of undermining and
destroying the opponent’s central pawns.

Take a look at the following diagram. White have fianchettoed both bishops. The important point to keep in
mind that if you fianchetto your bishops, especially the bishop next to your castled king, you don’t want to
exchange this bishop because it will seriously weaken your defensive ability and will create many
unprotected squares.
Let’s take a look at the real game in which white skillfully exploits open diagonal and is able to obtain a
decisive advantage, ultimately winning the game.

Congratulations, you have successfully completed the 14-days positional course! At this point you should
have a pretty good understanding of all most important positional elements of chess and should be able to
apply this knowledge in your own games.
Next, we will proceed with our training and focus on the endgames, which is another very important element
of the game. Ability to strategically think in the ending and be able to flawlessly play technical positions is
something that separates an amateur player from the master. For example, the World Chess Champion
Magnus Carlsen is able to win many equal position games because of his superior ability to play simple
endgames extremely well.
We will also learn in greater detail about the importance of opening preparation, and how that can be done
individually without hiring an expensive instructor.
