The other day, my partner and I found the only sequence of cards to defeat the opponents' game:
I was fooling around a little bit in third seat, opening my three-card club suit rather than my four-card diamond suit. I figured I could happily pass anything partner bid at the one-level. The opponent climbed up to 4S, and I decided to try a deceptive lead through the strong hand. I knew that West had a quite good hand and that partner had some values, so it wasn't a stretch to find dummy with KJxx of diamonds and partner with the queen. So I tabled a low diamond. When KQTx came down on the table, I no longer liked my lead. But partner was up to the task! The king of diamonds held trick one. When declarer led a low spade from dummy partner hopped up with his king, returned his second diamond, and got his diamond ruff. My ace of trumps was the setting trick. Nice play, pard!
