Competition Problem 101b
South to make five no-trumps against any defence.
Successful solvers: Steve Bloom, Ian Budden, Leigh Matheson, Sebastian Nowacki, Radu Mihai, Daniel de Lind van Wijngaarden, Dick Yuen, Wim van der Zijden
West's best lead (by far) is the ♦K, which North must duck. West continues with the ♦10, taken by North, South discarding a spade. The ♥4 to South's ♥A is followed by a club finesse, a second club, and the ♥5 to South's ♥K. The ♥J now subjects West to a seesaw squeeze. If West discards:
A. a spade, declarer gives up a spade and makes the rest.
B. a club, North plays low. South cashes the ♣K, North discarding a diamond, and plays a heart to North. As a spade discard still allows the suit to be set up, West is squeezed again and has to part with a diamond; but this allows North to cash the ♦A and run the ♠J to West, who has to lead into the split tenace at trick 12.
C. a diamond, North overtakes, cashes the ♦A and leads the ♥2 to South's ♥3 to squeeze West again. When West discards a club, South cashes the ♣K and endplays West by leading a low spade.
