Solution

On the 10, North plays low.

A.      If East plays low, so does South.  West continues with a trump (best), on which North plays the ♣8, East the ♣9, and South the ♣Q.  South cashes the ace of diamonds and leads a low club to the ♣K and ♣A.  East plays: 

1.       his last diamond:  South ruffs and continues with the Q to the K and A, J (discarding a spade from hand), re-enters hand by leading the ♣6 to the ♣7 and runs the rest of the trumps, throwing hearts from North.  The last trump squeezes East out of a spade, and South leads the ♠Q to set up three tricks in the suit.

2.       a heart:  this is covered by South and West and won by North.  After a diamond ruff, South leads the ♠Q to the ♠K and ♠A, cashes the J, and then runs the trumps for a simple major suit squeeze on East.

3.       the ♠10:  this is covered by South and West and won by North.  After a diamond ruff, South leads the Q to the K and A, cashes the J, and then runs the trumps as in (ii).

B.      If East plays high, South wins and leads another diamond.  North covers West’s card and East wins.  East returns a heart, won by North’s A.  South then throws his losing heart on the master diamond and forces out the ♣A (the play is not precise).  East leads the ♠10, on which South must pay low, and the ♠J wins.  The run of the trumps then squeezes West in spades and diamonds.
