Competition Problem 27
by Hugh Darwen
What lead by West defeats four hearts? How does South make four hearts against any other lead?
Successful solvers: Steve Bloom, Ian Budden, Jesper Dall, Serhat Erden, Mauro Fiorentini, Mike Hou, Daniël de Lind van Wijngaarden, Pengcheng Wu, Dick Yuen, Wim van der Zijden
Promotion: Steve Bloom is promoted to Expert Problemist, with 103 master points.
To defeat the contract, West must lead the ♠5!
If West instead leads the ♠K, South ducks, wins the spade continuation, plays a heart to North, a club back to hand, and the ♥A-K, North discarding clubs. The ♦K-Q must be allowed to hold, as must the third diamond, taken by North, whereupon South ruffs a spade and exits with the ♣Q. South's last trump wins a trick en passant.
If West leads a heart, North wins and leads a spade. To prevent the above line, East must rise with the ♠10, forcing South's ♠A. South plays as above anyway
