The following hand was published by Krysztof Martens in Przeglad
Brydzowy, 1/92. Since it took me some time and has a neat
solution, I thought I would pass it on:

S: K 8 7 2	S: A Q T 9
H: A 4		H: K J 8 2
D: Q 6 4	D: A K T 9
C: A K Q J	C: 6

Give a line guaranteed to make 7NT by West on the club 10 lead.

Answer follows. If you haven't solved it yet you can save it
for later or give up now.

Answer: Play AKQJ of clubs throwing hearts! King of hearts, A,K,Q
of diamonds.The position is now:
S: K 8 7 2	S: A Q T 9
H: A		H: -
D: _		D: T
If the diamond ten is high, claim, otherwise play the heart ace
throwing the diamond 10. If the diamond jack is still out, play
the other hand for 4 spades. If someone shows out on the heart
ace, you have a complete count.
