This hand is from the QF of the Mind Games in Lille where USA lost narrowly to Sweden despite this board. North (Rodwell) opened a precision 2D, South (meckstroth) bid 3S (invitational, actually preemptive invitational at this vul), shutting EW completely out of the auction. Since EW are cold for a VUL game, this rates to win IMPs, but the icing on the cake is when Meckstroth makes his contract.
Visualize the play after the play of the first few tricks. Trump lead to E's Ace, HK, H continued and ruffed. Club to the Ace, and diamond to the Ace. How do you proceed for nine tricks? there is no complete cross ruff, because if you play, d ruff, H ruff, d ruff, how do you come off dummy to ruff your last diamond? West can ruff the first club and play his remaining trump taking out your last dummy entry while dummy's clubs contain a loser.
Meckstroth accurately played to set up clubs and combine the chance of a cross ruff. It went club to East, Diamond tap, H ruff to hand, and a club from hand, and defence is now helpless with the fifth club coming into its own if they ruff in and play their last trump. Well played.
