Belladonna coup
Encyclopedia
The Belladonna coup is the play of a low card away from an accompanying high card, giving the opponents the impossible choice between setting up a winner for declarer and abandoning an attack on another suit.

The provenance of the following spectacular hand, which illustrates the Belladonna coup, is uncertain. A similar layout, with the same key play, is discussed by Victor Mollo

, the game's pre-eminent composer of single-dummy problems, composed it away from the table.

Against South's 4, West leads a small trump to East's 10 and South's J. South has several ways to play for ten tricks, which include finding the A onside (50% probability of success), or finding the diamonds 3-3 (36%). The best prospect is to ruff a heart in dummy, but the attack on trumps jeopardizes that plan. If South mis-times the play, the defense can manage to lead three rounds of trumps and win the K, before declarer can ruff the third heart.

Instead of relying on the position of the heart ace or a favorable diamond split, South played for the nearly sure thing by taking a safety play

 in hearts.

South led to dummy's K and played the 6 away from the K! This gave the E-W an impossible choice:
  • If East takes the trick with either the A or (if he has it) the Q, South eventually takes a heart trick by force of cards. East can continue trumps safely from his side, but South would no longer need to ruff a heart to reach ten tricks.
  • If West takes the trick – say, by capturing the J with the Q – then South might never take a heart trick. But West could not lead another spade without sacrificing his trump trick. South can't be stopped from either ruffing a heart in dummy, or (if West leads another trump) from taking five spades in his own hand.

Notice that South gives up the best chance of making a heart trick (leading toward the K). By giving up the chance for one trick in hearts, South virtually guarantees ten tricks (now only a very unlikely defensive minor suit ruff can defeat the contract).

Notice the presence of the avoidance play
Avoidance play
In contract bridge, avoidance play is a play technique whereby declarer prevents a particular defender from winning the trick, so as to eschew a dangerous lead from that hand. The dangerous hand is usually the one who is able to finesse through declarer's honors, to give a ruff to the partner or to...
