A friend sent me a problem that hits an area of great interest. When does one make a negative double? When does one stretch to show a particular suit? What is needed to reopen? When does the responder, having passed after an overcall, show strength?

Our methods are influenced by Phil’s thinking — the negative double promises the higher rankiing off-suit and EITHER the opening suit or the second suit. My corollary is that the bid of the LOWER off-suit can be a stretch. This means that a 2/1 in the lower off-suit might be 8 HCP with shape, a one-round force.

Anyway, here is the hand, neither vulnerable at IMP’s.

Spade Graphic Q J 9 8 6, Heart Graphic A K 8 7 5, Diamond Graphic K 6, Club Graphic Q.

Your RHO passes, you bid 1Spade Graphic, and LHO bids 2Club Graphic. It goes two passes to you. What is your action?
