If you're ever invited to join the Procrastinator's Club, accept: You
won't have to attend meetings since they'll never get around to having
one, but you may learn to postpone imprudent plays at bridge.
South put up dummy's queen of clubs, and when East played the king,
South won, took the A-K of spades to discard his last club, led a diamond
to his ace and lost a diamond. West led another spade, and East pitched
his last diamond as South ruffed.
South then took the A-K of trumps. (He feared that if he ruffed a
diamond instead, East might overruff with J-x or Q-x, and West would also
get a trump trick.) When West discarded, South ruffed a diamond with
dummy's last trump. East overruffed and cashed a trump, but South ruffed
the club return with his last trump and won the last two tricks with good
diamonds, making his game.
Both East and South needed to be procrastinators. East beats the
contract if he doesn't overruff the third diamond. South must ruff a spade
or club in his hand next, and when he leads a good diamond at Trick 11,
East ruffs, draws South's last trump and wins the setting trick with a
club.
But South is safe if he takes only one high trump before ruffing a
diamond in dummy. If East doesn't overruff, South returns to his hand with
the other high trump and leads good diamonds, and the defense gets only
two trumps and a diamond.
South may lose an overtrick if trumps break 3-2, but he protects his
contract against a 4-1 trump break.
