Solution

North wins with the K and leads the J to the Q and K.  South leads the K, on which North unblocks the 7.  East does best to let this win.  North is entered on a spade to lead the 2, South finessing the 6 as East plays low again.  Diamonds are continued until East plays the A, North discarding low clubs.  East does best now to return a spade, which South must win in hand with the Q.  Assuming East took the third round of diamonds, this is the position when South plays the penultimate diamond:

♠ A

♣ 43

♠ 54

 A4

 J10

♣ none

West can discard a heart but the last diamond completes the squeeze, of the kind that is called a guard squeeze.  A black suit discard gives declarer an extra winner in that suit, whereas discarding another heart gives South a tenace with the A4 over Eastís 102.  After Northís black suit aces the heart finesse brings home the contract.
