Uppercut (bridge)

Last updated

In contract bridge, an uppercut is a defensive play that involves one of the defenders ruffing high in the knowledge that an overruff by the declarer will result in the promotion of a trump card in their partner's hand into a winner. Thus, the technique presents a type of trump promotion.

It is best illustrated with an example:

Here declarer is South, spades are trump and the declarer can cash his two top spades, drawing all the defender's trumps, and claim the rest of the tricks. But if West, on the lead, plays a heart, covered by dummy's ace, East should ruff high with his jack of spades. Now, if South overruffs with the ace or king, West's queen will be promoted into a winner and the defense is assured of an otherwise unavailable trick.

Contract bridge Card game

Contract bridge, or simply bridge, is a trick-taking card game using a standard 52-card deck. In its basic format, it is played by four players in two competing partnerships, with partners sitting opposite each other around a table. Millions of people play bridge worldwide in clubs, tournaments, online and with friends at home, making it one of the world's most popular card games, particularly among seniors. The World Bridge Federation (WBF) is the governing body for international competitive bridge, with numerous other bodies governing bridge at the regional level.

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.

In the card game of contract bridge, to hold up means to play low to a trick led by the opponents, losing it intentionally in order to sever their communication. The primary purpose is to give as many tricks to opponents as needed to exhaust all the cards in the suit from one of their hands. If that hand regains the lead, it will not be able to put the partner on lead to cash its tricks. Hold up is one of basic techniques in play.

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. This is not always a bad thing—see uppercut below.

An entry, in trick-taking card games such as bridge, is a means of gaining the lead in a particular hand, i.e. winning the trick in that hand. Gaining the lead when some other player led to the previous trick is referred to as entering one's hand; a card that wins a trick to which another player made the lead is therefore known as an entry card.

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".

Smother play in contract bridge is a type of endplay where an opponent's apparent trump trick goes away.

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.

Coup en passant is a type of coup in contract bridge where trump trick(s) are "stolen" by trying to ruff a card after the player who has the master trump(s).

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.

Beer card

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.

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 cash one or more established winners. Avoidance play can be regarded as one type of safety play.

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.

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.

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.
