Crocodiles"
A three-card ending in a no-trump contract at matchpoints, South to play:
North
♠ -
♥
♦ J 6
♣ 2
West East
♠ - ♠ -
♥ - ♥ -
♦ 5 ♦ A 10
♣ Q 9 ♣ 10
South

♦ 8
♣ 7 6
South leads a club. If West plays the nine, East must win the ten and concede a trick to the diamond jack. As you can see, West must "swallow" partner's ten with the queen for E-W to score all three tricks.
This maneuver is aptly named a "crocodile coup". Not so easy when you don't see all the cards. But using clues from the auction and earlier play, the real-life West read the situation and did play the queen. Well done!
In a recent club game, an opportunity for this coup came up. This was the scenario:
East deals, neither side vul. Put yourself in West's seat, holding
♠ 7 3
♥ K J 10 6 3
♦ 10 8 4 3
♣ 9 8

Your aggressive negative double was motivated by the good hearts and fit for partner's diamonds--and being non-vulnerable! You lead the club nine:
North
♠ K J 8
♥ 8 7 2
♦ K 9 6
♣ Q J 5 2
West
♠ 7 3
♥ K J 10 6 3
♦ 10 8 4 3
♣ 9 8
Partner cashes the king-ace of clubs and leads the three to give you a ruff, South following with the four, six, and ten. Reading the three as suit-preference, you shift to a diamond. Partner wins the queen, South following with the jack, and plays his last club. Declarer ruffs with the spade ten, cashes the king-ace of spades, lays down the heart ace, and continues with the nine in this position:
North
♠ 9
♥ 8 7
♦ K 9
♣ -
West
♠ -
♥ K J 10
♦ 10 8
♣ -
It seems obvious to play the ten or jack, but stop and do some counting. Partner's hand counts out as 2=2=5=4, declarer's as 6=3=1=3. If declarer's hearts were ace-queen-third, why no finesse? Looks as if partner's remaining heart is the queen, especially as his three-club rebid would be a bit skinny without it. If you play the jack or ten, partner will be forced to overtake and concede a sluff-and-ruff, allowing declarer to escape for down one. So you rise with the king, and when partner drops the queen you cash the jack for down two. A "Crocodile Coup"!
The complete deal:
North
♠ K J 8

♣ Q J 5 2
West East
♠ 7 3 ♠ 5 2
♥ K J 10 6 3 ♥ Q 5
♦ 10 8 4 3 ♦ A Q 7 5 2
♣ 9 8 ♣ A K 7 3
South
♠ A Q 10 9 6 4
♥ A 9 4
♦ J
♣ 10 6 4
East did well to lead the fourth club to kill the queen, but should have made it easier for you by unblocking the heart queen on the ace. A wily South holding ace-queen-third of hearts would have been counting your high cards. With nothing in spades, diamonds, or clubs, you must hold the king-jack of hearts to justify your negative double--so declarer would spurn the finesse and tempt you to be a crocodile. If you "brilliantly" rise with the king, South scores the queen and sheds a few "crocodile tears" at your dismay!
