As South, how do you play each of the following hands to guarantee making your contract.

## Problem 1

 3 NT SouthNone Vul K Q 4 3 K 7 2 A 9 6 2 K 4 WestPassPass North2 3 NT EastPassAll Pass SOUTH1 NT2 Lead: 3 East plays 10 5 2 A Q 4 K J 4 3 A J 7 2 You play low from dummy and captureEast’s 10 with the ace. What next?

 A. Lead 2 to king B. Win A; finesse J C. Win K; finesse 9 D. Win K; finesse J

### Solution

You have seven top tricks and can guarantee one extra trick in diamonds with proper technique and another later in spades.

The key play is to cash the K then lead the 3 toward dummy. If West follows low both times, finesse the nine (if this loses to the 10, the Q must fall later). If West shows out on the second diamond lead, win the ace then lead toward your jack. This is called a “safety play” as it will succeed against any distribution, though it sometimes may cost an overtrick.

### Solution

You have nine top tricks and need one more in clubs or spades. Rather than rely on a finesse, there is a surefire endplay.

Draw trumps and cash all of the remaining diamond winners. Next win the A (key play) and exit with a club. Whoever wins must break the spade suit (else give you a ruff and a discard) and you are sure to win a 10th trick.

Note that if you finessed the Q and it lost, East would return a club; then you would have to lead spades yourself and probably fail.
