Meckwell reached the same 3NT as in the other room, after a Big club auction with artificial responses. Platnick won the first heart, which declarer has to duck, and found a spade shift, after which declarer can prevail double dummy, but is the only one to give him some trouble.
Please use next button to advance to the play where rodwell advances the 8 of clubs. This was, at double-dummy, a mistake. The correct play was the Ten of clubs, preserving the 8 for a possible later finesse against the J to bring in the suit if N rose Ace. A very difficult defence that beats the contract now is to rise CA because the clubs are blocked (That is, on the next round of clubs, declarer will be allowed to run the Ten, but the Queen in dummy is marooned.) When the C8 to the C9 finessing against the AJ worked, declarer needed to play a second heart, stripping North, and then play a club up, when North can be strip-endplayed to play Diamonds into the tenace. He instead chose to take a diamond finesse, playing South for some outside values. when this lost, Diamond defended most accurately, locking declarer in his hand where there is a loser by finding the only sequence of plays, Club Ace, then a red card (here, a heart). Declarer cashes his diamonds but has to concede a H at the finish for down one, and 12 IMPS to DIAMOND for a tied match.
