### Problem 1

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.

### Problem 2

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.

### Problem 3

You have eight top tricks. If you win the Q and lead the A and Q, whoever has the king may hold up; then you cannot set up the suit. If you then go after clubs, you may lose to the Q and K.

The key play is to lead the Q without cashing the ace. If it wins you have nine tricks and you can switch to clubs for three more.

What if someone takes the K and returns a spade? No problem! Cash the third spade and discard the A — a jettison play — then run the diamonds.
