Solution:
North wins the first trick, South discarding a diamond. North leads the other top club.
If East trumps, South overruffs and cashes the ♠A, North ruffs out West’s best spade, and one trump finesse captures East’s queen.
If East sheds a spade, South ruffs and cashes the ♠A, North ruffs out West’s best spade, and South wins the trump finesse and his remaining spades. North wins a top diamond and South ruffs a club. North wins another diamond and coups East’s trumps.
If East sheds a diamond, South sheds a spade and finesses trumps. North wins a top diamond and South finesses and runs all his trumps to triple squeeze West.
