East has shown a weak hand, but West may have a powerhouse, so that any action you take can be expensive. The double gets a few points because it can lead to the best result—either by a pass or a bid from partner.
4 SPADES—3 PTS.
It is poor policy to forgo certain profit in hopes of making game. I recommend that doubles of preemptive openings at the four level be allowed to stand unless doubler's partner has a highly distributional hand. Perhaps we can make game here, but the penalty should be comforting. This applies to hands where we cannot make game as well as to those where we can.
5 SPADES—5 PTS.
4 NO TRUMP—4 PTS.
6 HEARTS—2 PTS.
Partner has announced his interest in slam by first rebidding spades and then raising the heart suit; he should be assured that your three-heart bid also showed an interest in bigger things. Bidding the slam directly is not recommended, but four no trump (not Blackwood, of course) is also an acceptable move toward slam.
3 SPADES—5 PTS.
4 HEARTS—3 PTS.
4 CLUBS—1 PT.
Partner has announced a good hand with at most one spade. Your hand is worth the equivalent of an opening bid in support of clubs or hearts; a cue bid will alert partner to this fact. Four hearts bypasses a possible game in clubs. Four clubs, on the other hand, may dismiss a heart contract.
