Solution

South wins with the K and cashes one heart trick on which North discards the 10!  North wins two diamonds and then advances the K. 

A.      If East wins two spade tricks, North’s discards on South’s three major suit winners include the two remaining diamonds so that South can then cash the 9 and 5 to squeeze West in clubs and hearts.

B.      If East wins the first spade and then underleads the J, South wins with the 9 and plays a club (optionally cashing one top heart first).  If West plays low, North wins cheaply and leads the 9 to West’s 10.  Now North’s remaining low clubs will either win tricks (when West leads one into the tenace) or be discarded on South’s remaining top hearts.

C.      If East wins the first spade and leads a heart, the play is similar to B. except that North is entered on a diamond to lead a spade towards the ♠9.

D.      If East lets the ♠K win, North wins one more diamond and leads a middle club, which West must take.  If West exits with a heart, three rounds of hearts put West on play again and North’s club tenace and top diamond take the last three tricks.  If West instead exits with a club, North finesses and plays three rounds of the suit so that South’s heart winners will score.
