词条 | Belladonna coup |
释义 |
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,[1] which illustrates the Belladonna coup, is uncertain. A similar layout, with the same key play, is discussed by Victor Mollo.[2] Both sources attribute the coup to Giorgio Belladonna, for many years a cornerstone of the Italian Blue Team. (Belladonna later said that he could not recall having made the key play.) It is said that Belladonna played it as described in a European Community championship in Belgium during the 1980s. But it is also said that Paul Lukacs, the game's pre-eminent composer of single-dummy problems, composed it away from the table. {{BridgeHandNWES|Label = South in 4{{spades}} |Lead = Lead: {{spades}}2 |8 6 3|K 6|A K 5 3 2|K 6 4 |K 7 2|Q 10 5 3|10 6|9 8 3 2 |10 4|A 9 7 4|Q J 8 7|J 10 5 |A Q J 9 5|J 8 2|9 4|A Q 7}} Against South's 4{{Spades}}, West leads a small trump to East's {{Spades}}10 and South's {{Spades}}J. South has several ways to play for ten tricks, which include finding the {{Hearts}}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 {{Spades}}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 {{Diams}}K and played the {{Hearts}}6 away from the {{Hearts}}K! This gave the E-W an impossible choice: Notice that South gives up the best chance of making a heart trick (leading toward the {{Hearts}}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 theme in this deal. See also
