Bluff (poker)
In the card game of poker, a bluff is a bet or raise made with a hand which is not thought to be the best hand. ''To bluff'' is to make such a bet. The objective of a bluff is to induce a fold by at least one opponent who holds a better hand. The size and frequency of a bluff determines its profitability to the ''bluffer''. By extension, the phrase "calling somebody's bluff" is often used outside the context of poker to describe situations where one person demands that another proves a claim, or proves that they are not being deceptive. Pure bluff A pure bluff, or stone-cold bluff, is a bet or raise with an inferior hand that has little or no chance of improving. A player making a pure bluff believes they can win the pot only if all opponents fold. The pot odds for a bluff are the ratio of the size of the bluff to the pot. A pure bluff has a positive expectation (will be profitable in the long run) when the probability of being called by an opponent is lower than the pot o ...

Hypothetical
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research in a process beginning with an educated guess or thought. A different meaning of the term ''hypothesis'' is used in formal logic, to denote the antecedent of a proposition; thus in the proposition "If ''P'', then ''Q''", ''P'' denotes the hypothesis (or antecedent); ''Q'' can be called a consequent. ''P'' is the assumption in a (possibly counterfactual) ''What If'' question. The adjective ''hypothetical'', meaning "havin ...

Information Asymmetry
In contract theory and economics, information asymmetry deals with the study of decisions in transactions where one party has more or better information than the other. Information asymmetry creates an imbalance of power in transactions, which can sometimes cause the transactions to be inefficient, causing market failure in the worst case. Examples of this problem are adverse selection, moral hazard, and monopolies of knowledge. A common way to visualise information asymmetry is with a scale with one side being the seller and the other the buyer. When the seller has more or better information the transaction will more likely occur in the seller's favour ("the balance of power has shifted to the seller"). An example of this could be when a used car is sold, the seller is likely to have a much better understanding of the car's condition and hence its market value than the buyer, who can only estimate the market value based on the information provided by the seller and their own a ...

Spades (card Game)
Spades is a trick-taking card game devised in the United States in the 1930s. It can be played as either a partnership or solo/"cutthroat" game. The object is to take the number of tricks (also known as "books") that were bid before play of the hand began. Spades is a descendant of the Whist family of card games, which also includes Bridge, Hearts, and Oh Hell. Its major difference as compared to other Whist variants is that, instead of trump being decided by the highest bidder or at random, the Spade suit always trumps, hence the name. History Spades was devised in the Mid-West of the United States in the late 1930s. at pagat.com. Retrieved 11 September 2018.

Psychic Bid
Psychic bid (also psych, pronounced to rhyme with ''like'') is a bid in contract bridge that grossly misstates the power and/or suit lengths of one's hand. It is used deliberately to deceive the opponents. Normally, the psychic bid is made with a weak hand, overstating its overall strength, the length and strength in a particular suit, or both. (The noun is occasionally misspelled as ''psyche'', through confusion with Psyche, a character in a myth concerning Venus and Cupid.) Origins As an early frequent user of the technique, Dorothy Rice Sims is often thought to be the originator of the psychic bid; however, according to bridge player and writer, Albert Morehead, "She did not actually invent the psychic bid, though it is generally credited to her, but she did give it its name and she wrote the first and only book about it." and is regarded as having coined the term "psychic". Examples After two successive passes, this hand might be opened with 1 as a psych, trying to stop oppone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
