Try to stick to your path

Holly Lisle, a wide-ranging author best known for science fiction and fantasy, wrote, "If you don't accept responsibility for your own actions, then you are forever chained to a position of defense."

Partner opens one no-trump, and the next player overcalls two clubs, Cappelletti, showing a one-suiter somewhere. If responder passes, he will probably end on defense. But if he has some useful cards, he must take responsibility and get into the auction. The simplest agreement is to treat double as Stayman and every other bid as per the partnership's methods over one no-trump.

In this deal, after North doubles, East advances with two diamonds, which here is natural because he could pass. South passes to deny a four-card major. West rebids two hearts because he is so short in diamonds. What should North do now?
