With only them vulnerable at matchpoints, RHO dealt and passed as did I. LHO opened one club in third seat. Partner doubled (takeout) with the following: ♠ KJ5 ♡AKQJ ♢KJ2 ♣ T53.
I bid one spade, my longest suit. (With the benefit of hindsight, I should have jumped to two spades given my eight high card point, but that's another story.)
Opener rebid two clubs. Partner doubled again. I bid my second suit, two diamonds. LHO bid three clubs, buying the contract. Partner thought about bidding three hearts but elected to pass.W e got a bottom for "selling out" so low.
I was puzzled by partner's second double. Shouldn't he have raised to two spades with his hand? I would have put him on 16-18 points and raised him to three, which was the lowest level where we belonged. Alternatively, he could have bid two hearts treating his strong four card sequence as "five" (Marty Bergen recommends this.). He might also have raised my diamonds later.
Was any of these actions better than his last "pass?"
