My left hand opponent dealt and bid one diamond. Partner passed. My right hand opponent bid one spade. I wanted to double one diamond, but not one spade, with the following hand: ♠KQT5 ♡K92 ♢2 ♣ KT653.
So I passed. Left hand opponent rebid two diamonds. Partner and right hand opponent passed. Now I doubled, because the last opposing bid was diamonds.
Partner’s distribution was 4-3-4-2, with xxx in hearts and Qx in clubs. She passed because she had four cards each and her remaining seven honor points in suits bid by the opponents, and she thought she was "playing defense." She didn’t want to bid one of her short "round" suits (clubs or hearts)to take out my double.
I told her, "I had four spades to support a spade bid, and a only a singleton diamond opposite your four diamonds. We were not strong enough to defend, but we were strong enough to play two spades" (RHO opponent had five little ones for his bid).
Partner thought that my double showed shortness in both the opponents suits. I say that my bidding pattern showed shortness only in diamonds and suggested strength in spades. Are either of these interpretations more nearly correct than the other? Or do some world class partnerships use one, and some the other?
