Left hand opponent opened 1 heart. Partner doubled for takeout. Right hand opponent passed. I "had to" bid 2 clubs with something like (S) xxx (H) xx (D) Jxxx (C) Jxxx.
We were doubled for penalties, and went down five, (vulnerable) after partner partner laid down:
(s) Axxx (H) Kxx (D) Kxx (C) Qxx
In defending the takeout double, partner said, "I had 12 points and four spades. That's a standard takeout double."
I said, "I need 14 points for a vulnerable takeout. I don't even consider your hand worth 12 points (even though technically that's the case), because of the 4-3-3-3 distribution." What bothered me most about the double was not the minimum point count, but the "stranded" king, and three cards in the opponents' suit.
Give partner a better distribution by changing her hand to something like: (s) Axxxx (h)--- (d) KQxx (c) Kxxx, and I wouldn't have complained. Because all her "values" would have been OUTSIDE the opponents' suit, for offense, not defense.
Was partner right to make the double? Or was I right to protest it? Is vulnerability the deciding factor? In either case, why?
