Solution

South cashes the A and watches Westís discard, which obviously canít be a spade.

A.      If West discards a diamond, North throws the 8 and is entered on the A.  If West plays low, then that player is thrown in on a heart after the A and A have been cashed.  If West instead drops the K on this trick, then A and Q subject East to a squeeze in three suits.

B.      If West discards a heart, North must also discard a heart!  Now the A, A and Q are cashed, South discarding diamonds.  East discards a diamond on the Q, coming down to three singletons, the Q, K and K, while West has the master spade and J4.  West is thrown on the spade as South watches East discard.  If it is a heart or a club, South discards a club or heart, respectively, and takes the last two tricks with the A and the established heart or club winner.  If instead East discards the K, then South discards the A and North takes the last two tricks with the Q and 10.

Trap: If North discards a spade in line B, then the given ending will fail when East discards the K, and if line A is followed instead, then West can drop the J so that East takes the last three tricks with the Q, K, and 6.
