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.)
