You play in four hearts. Click on next until three rounds of trump are drawn. Here, i went wrong. How would YOU play?
You see, you need to eliminate East's diamond and clubs as he comes under pressure in exiting, you also need west to have the Ace of clubs. However, you need to be surgically precise
If you try CT, West ducks, you win in dummy, EAST will need to UNBLOCK his Jack or Nine. Now when you continue with a small club (My own play of spade was stupid) East will play his preserved small card and west will win club EIGHT. Now there is no endplay, when west exits with the Jack of spades. (On any other exit, say a diamond, East's D exit goes away as you ruff in dummy and you ruff yourself to hand stripping East of clubs, and then lead a spade up, if west plays low, you stick in the nine endplaying east, if west puts in the Jack, you play the Queen and when East wins he has only spades and has to lead away from the spade Ten to the split menace Ax and 9x
The correct play in the EIGHT card ending is a low club, the 7 to the King in dummy. Now they have no answer as you play a club back toward your TEN, EAST has to win Jack, and has to return a diamond (or dummy's CQ sets up), you ruff the diamond, ruff out his club exit and proceed as above.
