East opened two spades, a weak two-bid, with two first-round controls, which is not textbook. However, these days players are much more flexible, especially when void in the other major. North’s four diamonds was Leaping Michaels, showing a strong hand with at least 5-5 in hearts and diamonds.When you advanced with four hearts, North jumped to slam, assuming that you would have six useful points. If you didn’t, the bad result would be your fault!Assume that West has the heart king. But it is easy to get careless. Watch what happens if you ruff with dummy’s heart three at trick two. You cross to your hand with a club and run the heart jack, but the 4-0 break defeats you because you can take only one more finesse. Yes, you will try to return to your hand by ruffing the third diamond, but West will overruff for down one.Try ruffing at trick two with dummy’s nine. Play a club to your king, run the heart eight, run the heart jack, play a heart to dummy’s queen, and cash the heart ace.
