You are in 6 spades. Even though you bid diamonds as your second suit, Lefty opens the 2 of diamonds. You decide it is a singleton diamond. How do you play the hand? God has not blessed you with very good spots in diamonds. But has he given you what you need?

Ummm, another problem. Righty shows out on the first round of trumps.
