West’s opens the K, East plays the 4 and South the 8. The hold up in this situation has the added advantage that it leaves declarer with a major tenace, the A-J against Q-10, so that West cannot continue the suit without giving up an extra trick.

Outside the heart suit declarer has five top tricks and little chance of making any more than that. His problem is therefore clear cut: how to make four tricks from the hearts.

South gives up a trick to the Jack and makes the last two hearts when he enters dumy with the A
