Interference After Major Opening (803766)
What happens when the Opponents interfere after our side has opened 1♥ or 1♠.
They Overcall
1♥(1♠)2♥
1♥(2♠)3♥
3♥ = just a raise (but probably not a 6-count on the 3-level, maybe 7+ - 10). A cue-bid
of 3♠ would show a much better raise (in this case, enough for game).
1♥(1♠)2♣
2♣ = natural, forcing (but not to game—even if you play 2/1 game forcing).
What about a jump raise in competition?
1♥(1♠)3♥
In "Standard" this would be a limit raise. The modern (better) treatment is to use this
jump as weak (4 trumps and at most 7 points in support). I'd make this bid with
something like:
What do you do if you really have a limit raise (♠A 2♥K J 6 5♦9 8♣Q 6 5 3 2)?
1♥(1♠)2♠
Cue-bidding the opponent's suit should show a limit-raise (or better) in support. It shows
at least 3 trumps and 10 in support. Opener can attempt to sign off in 3 of the major with
a minimum. Of course, this cue-bid says nothing about spades—it is just a coincidence
that you have the ace in this example. If the cue-bidder has the "or better" he bids again
after opener tries to sign off.
They Double
1♥ (X) 3♥
The jump raise should again be played as preemptive, something like 0-7 points and 4-
card support (I wouldn't have "0" if vulnerable!). What if you really have a limit raise?
1♥ (X)2NT
This conventional raise (called "Jordan") is the modern (recommended) way to show a
limit (or better) raise after the opponents double. A redouble also shows a good hand
(10 ), but denies 3-card support. For a summary of all major-suit raises in and out of
competition.
What about bids that are not raises? A new suit should be natural, and most players use
it as forcing if it is on the one-level, non-forcing otherwise. So:
1♥ (X) 1♠
1♥ (X) 2♦
2♦= Natural, 5 (usually 6) or more diamonds, Not forcing (you would redouble with 10,
so this is usually less than 10)
