Diamond Dilemma

by Richard Pavlicek

Coping with preempts can be difficult, and you have your work cut out on this one. After East opens 3 , you double for takeout, West raises to game, and partner bids 4 NT. This is not Blackwood but asks you to choose a minor, and you happily oblige with 5 .

5 South None Vul	A 5 4 10 A 9 7 6 2 6 5 4 3			West 4 Pass	North 4 NT Pass	EAST 3 Pass Pass	South Dbl 5
Q J 10 9 8 A J 2 K J 10 9 8			7 6 K 9 8 7 6 5 4 3 5 4 7
Lead: Q	K 3 2 Q Q J 10 8 3 A K Q 2

You have 10 easy tricks with the favorable trump lie, but the mirror distribution leaves no obvious way to develop an 11th. With West protecting both black suits, a squeeze may be in the offing; but how can you rectify the count without giving up one of your threats? Any ideas?

Make 5 against any defense.

Solution

Your first thoughts might be to draw trumps and exit with a heart, but this won’t work because West can win and exit safely, no matter how many black winners you cash early. If only you could arrange a throw-in against East.

Therein lies the solution, but it requires a devious scheme.

5 South	A 5 4		Trick	Lead	2nd	3rd	4th
	10		1 W	Q	A	6	2
	A 9 7 6 2		2 N	10	3	Q	A
	6 5 4 3		3 W	J	4	7	K
Q J 10 9 8		7 6	4 S	Q	K	A	4
A J 2		K 9 8 7 6 5 4 3	5 N	3	7	A	8
K		5 4	continued below…
J 10 9 8		7
	K 3 2
	Q
	Q J 10 8 3
Lead: Q	A K Q 2

Win the A (or the king) and give up a heart. Assume a spade return (no defense matters) to the king, then lead the Q; king, ace. Do not draw the outstanding trump. Return to hand with the A to reach this position:

win 7	5		Trick	Lead	2nd	3rd	4th
	—		6 S	K	9	4	4!
	9 7 6 2		7 S	3	8	2!	5
	6 5 4		8 E	K	10	J	5
10 9 8		—	9 S	J	9	6	5
J 2		K 9 8 7 6 5 4	10 S	8	2	9	6
—		5	11 N	7	7	3	?
J 10 9		—	West is squeezed
	3
	—
	J 10 8 3
South leads	K Q 2

Next cash the K, which East smartly refuses to ruff; else he must concede a ruff-sluff, resulting in West being squeezed. Well, if East wants to play that way, you must make him an offer he can’t refuse. Lead the 3, and when West shows out, duck in dummy to force East to win the 5. Ruff the heart return with the 10, throwing a club from dummy. Win the J, overtake the 8 with the nine, then lead dummy’s last diamond, throwing your spade. West is squeezed in the black suits.

The forced ruff-sluff from East only broke even for the trick you gave away in diamonds, but it rectified the count for a squeeze without wasting a black-suit threat.
