A neat defense from Gatlinburg

In the Friday two-session Swiss teams in Gatlinburg last week, Robert Todd and I put together a nice defense. E-W subsided in 2NT after an invitational sequence in which West may or may not have had four spades. I got off to the lead of the two of diamonds. Declarer played low from dummy, and Robert made the very thoughtful play of the seven! Declarer won with the king, cashed the king of clubs (Robert playing the six, his lowest, as a Smith echo - showing that he liked my opening lead), and played a diamond up. Not yet believing that partner had made the good play in diamonds, I split my honors to guarantee me a trick in the suit if RHO had KQx(x). East let me hold the trick. Not really seeing anything else constructive to do, I played another low diamond. Dummy won and declarer pitched a heart. A club was led to the ace, and a spade to the queen. Two more rounds of clubs were played, ending on the table, and I pitched down to AJ of spades, KJ of hearts, and the good jack of diamonds. A heart was led to my jack; I cashed the good diamond and exited the now-stiff king of hearts to the now-stiff ace, and a spade through the queen was our sixth trick for down one. At the other table, our teammates were +400 in 3NT!
