Lucky

A speculative double. In fact, E/W can make the contract, but did not. His best guess after the spade attack is to put the ♣K to North and establish an access to the table to finesse for the king of diamonds. Instead, Lia played the ♦A, hoping for the ♦K to drop or be with North.

In fact, Lia played that way on some tables for down two, and made two overtricks on other tables. My result was a lonely, very lucky top.
