Competition Problem 36
composed by Hugh Darwen
presented for solving in February, 2008
South to make four spades against any black suit lead by West.
Successful solvers: Steve Bloom, Ian Budden, Vincent Labbé, Rajeswar Tewari, Daniel de Lind van Wijngaarden, Dick Yuen, Wim van der Zijden.
A. If West leads a spade, East covers and South wins. South must lead a diamond, allowing West's ♦K (best) to hold! Whatever West now returns, North-South make, in some appropriate order a diamond, two more spades, possibly a heart, and three clubs. Now the fourth club is led, forcing West to ruff and play hearts. East cannot make more than one heart trick.
B. If West leads a club, North plays high. East covers (best) and South wins. North is entered on a second club to lead a heart. East plays low (best) and South wins. South advances the ♣10.
1. If East discards a diamond, North is entered on a diamond and the contract can now easily be made by leading a heart. (It can also be made by leading a spade.)
2. If East ruffs, declarer can contrive to win, in some appropriate order, two hearts, two spades, and two diamonds. East makes the ♥A at some stage in the process. East is put on play at trick 10 with a third diamond so that North and South make their remaining trumps separately while West underruffs. If West tries to spoil this by ruffing the third diamond and leading a trump, the last trick is won in clubs.
