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:
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.
