Solution

South captures Eastís Q (best) with the A and leads the J, North overtaking with the Q if West ducks, otherwise winning with the A.  North leads the Q, which is allowed to hold, followed by the 5, which East must duck.  Winning with the 10, South cashes the A and enters North on a heart.  East can discard a spade.  North now runs the clubs to squeeze both opponents.  East and South both discard a spade and a diamond on the first two and West discards a heart, leaving this:

♠ J

 432

 none

♣ 8

♠ Q43

 97

 none

♣ none

♠ 1098

 none

 K9

♣ none

♠ AK5

 none

 J3

♣ none

On the last club, if East discards

A.      a diamond, South and West both discard spades.  South comes to hand on a spade to give up a diamond and win the last two tricks.

B.      a spade, South discards a diamond and West is squeezed out of a heart.  Southís last diamond goes on a heart lost to West, who either lets North in on the J to make the established heart winners or leads the Q to let South score the K, A, and 5.
