Competition Problem 34
composed by Jeff
South to make six no-trumps. West leads the ♥Q.
Successful solvers: Steve Bloom, Ian Budden, Rajeswar Tewari, each of whom suggested DR6. Nearly all of the remaining submissions omitted either or both of variations B and C and also the "fourth variation".
Annual result, 2007: Steve Bloom is the runaway winner, with 54 Master Points (15 from composing) and 4 Star Points. Wim van der Zijden is the runner-up with 35 (all from solving) and 1. Ian Budden takes third place with 23 (6 from composing) and 2.
North wins and leads the ♣10, covered by East (if not, see the final paragraph) and South. South leads the ♦8, North overtaking even when West plays low. The ♣9 is covered by East and South, who leads the ♦5, North winning as cheaply as possible. North's ♣6 is allowed to hold (best), West discarding a diamond. South comes to hand on the last club, forcing West to discard another diamond, coming down to three of each major suit:
South's diamond lead now subjects West to a seesaw squeeze. Which diamond South leads depends on which one West played on the second round:
A. If it was the ♦4, South leads the ♦8 and North wins with the ♦J or ♦A depending on which major suit West now unguards.
B. If it was the ♦9, South leads the ♦8 and North overtakes or ducks.
C. If it was the ♦K, South leads the ♦Q and North plays the ♦6 or ♦J.
The ace of the unguarded suit is followed by the last diamond to put the lead in the hand that now establishes a winner in that suit with the other ace as entry to it.
A fourth variation arises if East ducks the first two rounds of clubs. In that case South comes to hand on a club, forcing West to discard a diamond. This time South leads the ♦Q, which holds, followed by a diamond to North's ♦J. The last club forces West to discard the ♦K, allowing the seesaw squeeze to follow as before.
