composed by Hugh Darwen
presented for solving in July, 2008
South to make six clubs against any lead and defence.
Successful solvers: Vincent Labbé, Rajeswar Tewari, Daniel de Lind van Wijngaarden, Dick Yuen, Wim van der Zijden.
First, I am indebted to Barry Rigal, who showed me the unusual repeated squeeze on which this problem is based. Has anybody seen its like before?
If West leads from a major suit declarer can easily aim to give up a heart to East, ruff the third rounds of both spades and diamonds and run the trumps to squeeze West in the red suits.
If West leads a minor suit, a low diamond is best. South wins with the ♦K and plays four rounds of trumps, finessing against East's ♣10. West safely discards two hearts on the second and third but is squeezed by the fourth:
A. If West discards a spade, North wins a spade finesse and gives up a heart to East. North wins the return and cashes the other pointed suit ace. South ruffs a diamond and scores the ♠Q to squeeze West again, in the red suits. (Alternatively, North can cash the ♦A and ♠A and ruff a diamond. A heart is ducked to East, whose spade return yields the same red suit squeeze.)
B. If West discards a third heart, declarer gives up a heart (immediately or by playing the ♥A first). North wins the return and now the third round of hearts, won by South's ♥J, brings about a ruffing squeeze against West in spades and diamonds.
C. If West discards a diamond, the ♦10 goes to ♦J, ♦A, and ♦9 (best). South ruffs a diamond to set up North's fourth and plays a spade to the ♠J. North advances the ♦4. West will discard a spade because a heart discard simply allows a heart winner to be established. If East discards
1. the ♥Q, South discards a spade. North cashes the ♠A and exits with a low heart to endplay West.
2. a spade, South discards a heart. North cashes the ♠A and leads a low heart. If East wins, the ♠Q and ♥A take the last two tricks; if West wins, the ♥J and ♠Q take them.
