A 4 [Heart]—5 3 [Heart]—2 2 [Club]—minus 1
You must shut out the spade suit, and three hearts is unlikely to do it. Besides, there is a chance you can make four hearts. Two clubs is so inadequate that it draws my first minus award.
B PASS—5 2 [Club]—2 3 [Club]—1
You are not strong enough to redouble, far too strong to bid only two clubs and too weak to bid three clubs, if you play that as strength-showing. The pass gives you a better chance to judge the winning action later.
A 1 N. T.—5 PASS—3 DBL.—1
The no-trump bid gives your side the best chance. A pass may work well if partner is busted, or if opener's partner responds one no trump and your partner can leave in your subsequent penalty double. A takeout double will leave you floundering, but it is better than a two-club overcall.
B DBL.—5 1 N. T.—2 1 [Heart]—1
You would prefer four cards in each major but partner will probably be able to struggle along with three-card support in spades. One no trump may uncover the best spot if partner takes out. One heart gets a point because it is slightly better than a pass.
SOLUTIONS TO PLAYING PROBLEMS
[King of Hearts]—5 [5 of Diamonds]—3 [Jack of Diamonds]—2
Your partner's double and subsequent heart raise suggest that one opponent will have no more than one heart. You should make every effort to hold the lead so that after a look at dummy you can decide what shift is most promising. A low diamond lead may succeed because it gives your partner a chance to win the trick and put you back in by underleading the ace of hearts. The jack of diamonds gives partner the idea that you hold the 10 or a doubleton.
[King of Hearts], then low heart for a finesse against East's queen—5. Low heart for an immediate finesse with the [9 of Hearts]—2. Cash two top hearts in any order—minus 2.
