In contract bridge and similar games, a finesse is a type of card play technique which will enable a player to win an additional trick or tricks should there be a favorable position of one or more cards in the hands of the opponents.
Safety play in contract bridge is a generic name for plays in which declarer maximizes the chances for fulfilling the contract by ignoring a chance for a higher score. Declarer uses safety plays to cope with potentially unfavorable layouts of the opponent's cards. In so doing, declarer attempts to ensure the contract even in worst-case scenarios, by giving up the possibility of overtricks.
In trick-taking games, to ruff means to play a trump card to a trick. According to the rules of most games, a player must have no cards left in the suit led in order to ruff. Since the other players are constrained to follow suit if they can, even a low trump can win a trick. In some games, like Pinochle and Preferans, the player who cannot follow suit is required to ruff. In others, like Bridge and Whist, he may instead discard. Normally, ruffing will win a trick. But it is also possible that a subsequent player will overruff. Historically, ruff meant to "rob" i.e. exchange a card with the stock.
In contract bridge, coup is a generic name for various techniques in play, denoting a specific pattern in the lie and the play of cards; it is a special play maneuver by declarer.
An endplay, in bridge and similar games, is a tactical play where a defender is put on lead at a strategic moment, and then has to make a play that loses one or more tricks. Most commonly the losing play either constitutes a free finesse, or else it gives declarer a ruff and discard. In a case where declarer has no entries to dummy, the defender may also be endplayed into leading a suit which can be won in that hand.
In contract bridge, the trump squeeze is a variant of the simple squeeze in which one threat is a suit that if unguarded can be established by ruffing.
The Devil's Coup is a declarer play in contract bridge that prevents the defense from taking an apparently natural trump trick – often called "the disappearing trump trick".
Morton's fork is a coup in contract bridge that forces an opponent to choose between
- letting declarer establish extra tricks in the suit led; or
- losing the opportunity to win any trick in the suit led.
Smother play in contract bridge is a type of endplay where an opponent's apparent trump trick goes away.
Scissors coup is a type of coup in bridge, so named because it cuts communications between defenders. By discarding a card or cards either from declarer's hand or from dummy or both, declarer can stop them from transferring the lead between each other, usually to prevent a defensive ruff.
A winkle squeeze is a rare squeeze/endplay in contract bridge in which a trick is offered to the defenders but whichever wins the trick is then endplayed. Often one defender would be forced to offer a finesse or ruff and discard while the other could overtake and thereby promote a trick in that suit for declarer. The winkle squeeze was named and analyzed by Terence Reese in Master Play in Contract Bridge.
The trump coup is a contract bridge coup used when the hand on lead has no trumps remaining, while the next hand in rotation has only trumps, including a high one that would have been onside for a direct finesse if a trump could have been led. The play involves forcing that hand to ruff, only to be overruffed. A similar motive is met in coup en passant, where indirect finesse is used instead of direct.
These terms are used in contract bridge, using duplicate or rubber scoring. Some of them are also used in whist, bid whist, the obsolete game auction bridge, and other trick-taking games. This glossary supplements the Glossary of card game terms.
Trump promotion is a technique in contract bridge where the defenders create an otherwise non-existing trump trick for themselves. The most common type of trump promotion occurs when one defender plays a side suit through, in which both the declarer's hand and the other defender are void:
Loser on loser play is a type of declarer's play in contract bridge, usually in trump contracts, where the declarer discards a loser card on an opponent's winner, instead of ruffing.
In trick-taking card games such as bridge, the beer card is a name informally given to the seven of diamonds. Players may agree that if a player wins the last trick of a hand with the 7♦, their partner must buy them a beer. This is not considered as part of the rules of these games, but is an optional and informal side-bet between players. This practice likely originates from Danish Tarok or Skat in the middle of the 20th century.
Backwash squeeze is a rare squeeze which involves squeezing an opponent which lies behind declarer's menace. A variation of this, known as the "Sydney Squeeze" or "Seres Squeeze", was discovered in play at a rubber bridge game in Sydney, Australia in 1965, by the Australian great Tim Seres; it was later attested by famous bridge theorist Géza Ottlik in an article in The Bridge World in 1974, as well as in his famous book Adventures in Card Play, co-authored with Hugh Kelsey.
In the card game of bridge, tempo is the timing advantage of being on lead, thus being first to initiate one's play strategy to develop tricks for one's side. Tempo also refers to the speed of play and more generally the rhythm of play over several tricks.
A forcing defense in contract bridge aims to force declarer to repeatedly ruff the defenders' leads. If this can be done often enough, declarer eventually runs out of trumps and may lose control of the hand. A forcing defense is therefore applicable only to contracts played in a trump suit.
In bridge, a knockout squeeze is a squeeze in three suits, one of which is the trump suit. The defender's trump holding is needed to prevent declarer from making a successful play involving trumps, including one as prosaic as ruffing a loser. Because the knockout squeeze does not threaten to promote declarer's trumps to winners it is termed a non-material squeeze. Other non-material squeezes include entry squeezes, single-suit squeezes and winkles.
