Ruffing an opponent's loser
Brad Coles

Everyone knows that when your opponent leads towards an ace in dummy, and you are void in the suit, it is usually wrong to ruff in front of the ace. You’d be ruffing a loser, leaving you with one fewer trump while your opponent still has the ace to cash later.
On this deal from the Mutton Cup, a popular Individual tournament in Madrid, Ramon Gomez of Spain faced an unusual variation of that principle:
 Dealer South, neither side vulnerable

North leads the singleton club, won by declarer’s ace, and declarer plays two rounds of trumps. In with the ]K, South switches to a spade.
If declarer ruffs this trick, North will follow low, and the defenders will still have the three top spades. Instead, Gomez discarded a diamond on this trick, letting North win with the queen. North continued with a low spade, and Gomez inserted dummy’s nine, forcing South’s king and promoting dummy’s jack as a stopper.
Declarer ruffed this trick, and now was on track to make an overtrick, with just the ]J and {K to lose. However, not believing that South’s ]K was a doubleton, declarer made his only two errors of the deal on the next trick: he cashed the queen of trumps, discarding a low diamond from dummy. Now North was threatening to get on lead with the {K, cash the top trump, and cash the [A for a fifth trick (crucial at Matchpoint scoring).
Declarer recovered the position by giving North a chance to go wrong. He cashed out the clubs, and the fourth round was ruffed and overruffed with the last two trumps, leaving North on lead in this ending:

With a full count on the deal, what would you lead from the North hand now? At the table, North cashed the [A, which was his last trick. If he next continued with the {K, the West hand would be high, while a low diamond exit would be won with the queen, at which point the East hand is high. Either way, nine tricks.
A better defence from North would have been a low diamond immediately, breaking declarer’s communications. Dummy can take the {Q and long club, but then has to concede two spade tricks into North’s ace-ten, for just eight tricks.
Note that declarer could have put North under more pressure by discarding the {Q, and keeping a low one. Then he could have won a low diamond exit in hand, and the diamonds would have been high for ten tricks. In that scenario, North would have to cash the [A to hold the contract to nine.
North could still have had the last word, though: if he refuses to overruff the club, instead discarding his spade loser, he will be left with one fewer spade and one extra trump in the four-card ending. Now, all declarer can do is cash the {A for eight tricks.
As it turns out, making nine tricks was only an average board, while eight tricks would have been just 27%. South’s spade switch at trick four ensured a good score for NS; most declarers made ten tricks when the spade switch was not found.
