DEFENSE VS UNDISCIPLINED WEAK TWO BIDS
An "undisciplined" weak two bid is defined as one that is quite
likely to based on a trashy suit, maybe only five long.
This defense, aimed at penalizing the opponents, applies only when
the vulnerability is favorable or equal, and only against weak two
bids in a major suit. When the vulnerability is unfavorable, or
when the opening is 2D, use standard defensive bidding as described
in DEFENSE VS STANDARD WEAK TWO BIDS. When vulnerable vs non-
vulnerable, a profitable penalty is unlikely if you have game your
way; over 2D, the takeout double is too valuable to give up.
While this defense is primarily for match point contests (doubling
the opponents into game is not uncommon, and slam is sometimes
missed), it can also be used for short IMP matches, such as Swiss
teams. For long IMP matches, it should be used only if the
opponents are particularly wild bidders.
Here's the special defense, which applies to the direct (i.e., not
reopening) position by an unpassed hand only:
-- A double is optional, showing 14 HCP or more and at least three
defensive tricks in a balanced hand. With a big hand a singleton
in an unbid minor is all right, but you must have a place to go if
partner bids that minor. With a marginal double it is good to have
a fair holding in the opposing suit, and outside aces/kings rather
than queens/jacks. You want to be ready with some good defense if
partner takes the likely option of passing the double.
-- A 2NT overcall is for takeout, showing a three-suited hand with
at least four cards in the unbid major and shortness in the
opposing suit. It is not forcing, since a really big hand can cue
bid. Partner can pass with the opposing suit stopped, 7 HCP or
less, and no better call. He should not jump to the four level in
a suit without 8 HCP or so, since the 2NT bid is limited. A jump
to 4C is natural, not Gerber, since the 2NT bid is artificial. A
jump to 4NT is regular Blackwood, as it is after a takeout double.
-- A cue bid is usually based on a good two-suited hand but (since
a 2NT bid is not forcing) sometimes a big three-suiter. A correc-
tion bid shows the two-suiter when partner perversely bids the
fourth suit:
South West North East
2S 3S Pass 4D
Pass 4H - hearts and clubs
-- Other actions are the same as when defending against standard
weak two bids.
