B 3 N.T.—5 2 N.T. 3 2 [Spade]/3 [Club]—1
Partner's double must include hearts, and you have everything else, plus enough values to insist on a game contract. Two no trump is an underbid. Two spades or three clubs—well, I guess I can think of worse.
A REDBL.—5 PASS—3 2 N.T.—2
A redouble does not promise support for partner's suit but asks him to let you have a whack at the opponents' takeout—which should prove profitable if they bid hearts or clubs. Pass is rated over two no trump, for it enhances your chance of collecting a penalty that may be worth more than the game you might make.
B REDBL.—5 4 [Heart]—3 3 [Club]—2
Since the opponents probably have a safe resting spot in spades, this redouble is not intended to score a penalty but to give a picture of your high-card strength. Three clubs (if played as forcing) and four hearts are superior to three hearts—a weak bid.
A 1 [Spade]—5 1 N.T.—1 PASS 1
You have no long suit other than hearts, so you must make your cheapest bid, though it be in a three-card suit. You do not have the top-card strength promised by a one-no-trump response, and your trumps are not strong enough to pass.
No other bid warrants any credit, and a craven runout to hearts should score a minus. Your diamond support is far better than partner can expect. If unhappy, he can redouble to ask you to find a better spot.
A PASS—5 1 N.T.—2
This time your trump suit is so strong that if partner leads it—as requested by your pass—the opponents may be in for a resounding penalty. Besides, your hand may be of little value if partner plays in a suit. One no trump promises general strength.
B 2 [Heart]—5 3 [Heart]—2
You are close to making an encouraging response, but if partner can cover enough of your losers to make game, he will probably bid again. The opponents may rebid in spades. Then a three-heart bid will give a clearer picture than an immediate jump.
