Pronunciation: [dˈʌbə͡l dˈʌmi] (IPA) 
The term "double dummy" is commonly used in the context of bridge card games. The correct spelling of this term is /ˈdʌbəl ˈdʌmi/, with the stress on the first and third syllables. In phonetic transcription, it is written as "DUB-uhl DUH-mee". The term refers to a scenario in which both players in a partnership hold their cards facing upwards on the table, allowing them to see and plan each other's moves.
Double dummy refers to a technique or method used in card games, particularly in the game of contract bridge. It involves analyzing and playing a hand of cards by assuming complete knowledge of both your own hand and your partner's hand, as well as all the cards held by the opponents. In other words, it is the art of playing as if you and your partner can see each other's cards and can make optimal decisions based on this knowledge.
The term "double dummy" derives from the fact that two players are essentially playing the hand "dummy" or "blind," with full knowledge of all cards held by both sides. This allows players to plan their moves and anticipate possible outcomes more accurately. It is considered a highly advanced and strategic approach, as it requires the ability to evaluate various possible scenarios based on limited information.
Double dummy analysis helps players refine their bidding, declarer play, and defense techniques, and is often used in advanced training or competitive settings. It enables players to find optimal lines of play based on the best possible distribution of cards amongst opponents, regardless of the actual distribution in the real game. Double dummy analysis also facilitates studying and solving specific card combinations or problems.
Overall, double dummy is a method that allows players to exercise their judgment and decision-making skills by assuming they have perfect knowledge of all the cards involved in a particular hand of a game like bridge.
The term "double dummy" originates from the game of bridge, specifically bridge analysis and problem-solving. In bridge, "dummy" refers to one of the two non-playing hands, which is placed face-up on the table. This is done in order to facilitate the opponent's understanding of the bidding and play.
The term "double dummy" is used to describe a type of bridge problem or analysis where both declarer (the player who won the contract) and dummy hands are viewable to the player trying to solve the problem. This means that the positions and values of all the cards in both hands are known, unlike in regular play where only one hand is visible to a player.
So, "double dummy" refers to the situation where a player has complete knowledge of both the declarer's hand and dummy's hand in a bridge problem or analysis.
