Partner opened with 3 spades (pre-empt). I passed with (s) xx (h) KQx (d) KQxx (c) AJxx.
That's because I was expecting something like the following (with or without the side jacks):
(s) KQxxxxx (h) Jxx (d) Jx (c) x.
Partner's spade suit was actually AKQxxxx, with the other suits as listed above. So we missed a cold game in spades or possibly no trump.
I said, "You had eleven high card points. That, together with your distributional strength was an opening hand. Opposite my (better than) opening hand, that meant game."
She said, "I bid three to show you may seven card suit."
I said, "That's not nearly as important as your high card strength. Your length will become clear when you rebid."
Was I right to pass, in expectation of the weaker version of her hand, given that three spades is quite high? Should partner have bid one spade if she didn't want me to pass her out with my 15 points?
