Competition Problem 11
by J-M. Maréchal
South to make five diamonds. West leads the ♣6.
Successful solvers: Robin Adey, Bob Bignall, Jean-Marc Bihl, Steve Bloom, Ian Budden, Simon Cheung, Helge Leonhardsen, Derek Lu, Bircan Öztürk, Andrew Prothero, Wim van der Zijden
North wins and leads a spade to South's ♠A. Diamonds are led from the top until West covers, when North wins and leads a spade for South to ruff. Any remaining trumps are drawn and then South leads a low heart.
A. If West ducks, North's ♥10 forces the ♥K. North wins the club return and South ruffs a spade before exiting to West on a heart. North ruffs the next heart, which squeezes East in the black suits.
B. If West wins with the ♥J, North plays low. South ruffs the spade continuation and leads a club to North, whose last trump triple-squeezes East before South. A black suit discard is immediately fatal, so East discards the ♥K. South throws a club and now North's ♥10 is good enough to knock out the ♥A and set up South's ♥Q.
