LIMIT JUMP RAISE IN A MAJOR
The jump raise of a major suit is not forcing, whether made in
competition or not. Requirements are:
-- Four-card trump support, headed by queen or better, or any five
-- About 11 points counting distribution, a game-try hand
-- A balanced hand with generally scattered strength
The limit jump raise implies that it is not important where
opener's strength lies; any high cards in his hand will be useful.
This in turn implies a balanced hand for the raise, with no good
side suit. When the degree of fit may be important, as when
responder has a short suit or a good side suit, it is usually
better to make a temporizing bid in a new suit before inviting
game. This action will help opener in judging whether to bid game
or not when he has a close decision.
Partner opens 1S and you have S-Q1042 H-K3 D-AJ42 C-976. This is
a good raise to 3S. But with S-Q1042 H-J86 D-AQ943 C-8 respond 2D
and bid 3S on the next round. The bidding might go:
Opener Responder
1S 2D
2S 3S
or: Opener Responder
1S 2D
2H 3S - not forcing
Note that responder must go to the three level to raise spades. A
2S rebid over 2H would be a preference, not a raise, showing
something like S-J3 H-4 D-AJ8763 C-J764.
In competition one must usually forget about bidding a side suit,
both for preemptive reasons and because the overcall often takes
away bidding space. If you have S-KJ54 H-63 D-AQ763 C-95 and
partner opens 1S, then next hand bids 2H, you cannot bid 3D--you
won't know what to do if partner bids 3S--so you jump to 3S over
2H.
If RHO had passed, you would have bid 2D before raising spades. If
RHO had bid 2C instead of 2H, you could bid 2D, but even then 3S
is better. An immediate jump might shut out a club raise by LHO,
and partner does not need much guidance as to fit. With an opponent
bidding clubs, he will know that a singleton or xxx in diamonds is
a poor holding.
The trump support is sometimes not up to par in competition.
Suppose partner opens 1S, RHO bids 2H, and you have S-KQ8 H-7
D-A10874 C-J953. This hand is too good for a 2S raise, but 3D over
2H is out of the question; the hand is not good enough. In a case
like this you must bid 3S with three-card support.
When in doubt whether to give a single or double raise, look at
the trumps. With good four-card support, lean toward the jump
raise. A jump with three trumps should only be made when a single
raise is completely ruled out.
As with the preceding hand, a jump raise in competition will often
be made with an unbalanced hand.
A passed hand jump raise may also have an unbalanced hand and/or
trumps weaker than Qxxx, perhaps only three-card support. See
chapter RESPONSES BY A PASSED HAND.
A limit raiser cannot use Blackwood, so his 4NT bids are natural:
Opener Responder
1H 3H
4C 4D
4S 4NT - natural, club king
A jump raise over an opposing takeout double is a weak preemptive
bid. A limit raise is shown by an artificial jump to 2NT when the
hand lacks sufficient HCP for a redouble. See chapter BIDDING OVER
A DOUBLE.
Asking for Shortness
Opener's cheapest rebid asks responder if she has a short suit:
Opener Responder
1 3
3? 4/4 - singleton or void
3NT - short spades
4 - no short suit
Opener Responder
1 3
3NT? 4/4/4 - short suit
4 - no short suit
Any other new suit bid by opener is a cue bid, or possibly a second
suit, inviting slam and seeking more information from responder.
