Once the diamond is led go up with the Ace and completely rely on clubs to dump a diamond loser the Queen, not a spade as you already have spade shortage in the dummy.

Win the first trick with dummy’s Ace. Now cash one club just in case there is a singleton Queen about. Cash one of dummy’s top trumps and lead a trump to hand and when trumps break 2:2 now take the club finesse. When it works you can dump your Diamond loser on dummy’s 13^th Club. You will now just concede one Spade bringing your contract home by way of 1 Spade, 5 trumps, 1 Diamond 4 clubs and 1 Diamond ruffed in the short hand.

You can also view  watch the following movie to see how the hand pans out. (You need bridgvu.exe programme  or BridgeBase programme on your machine already to view it ) and it is available free from
