Hustling is the deceptive act of disguising one's skill in a sport or game with the intent of luring someone of probably lesser skill into gambling with the hustler, as a form of both a confidence trick and match fixing. It is most commonly associated with, and originated in pocket billiards , but also can be performed with regard to other sports and gambling activities. Hustlers may also engage in "sharking"—distracting, disheartening, enraging, or even threatening their opponents—to throw them off. Hustlers are thus often called "pool sharks". Professional and semi-pro hustlers sometimes work with a "stakehorse"—a person who provides the money for the hustler to bet with —in exchange for a substantial portion of all winnings. Another form of hustling is challenging "marks" to bet on trick shots that seem nearly impossible but at which the hustler is exceptionally skilled.
Chess hustlers are quite common in urban areas in the United States and elsewhere, often offering speed chess against any takers. Unlike most hustlers, chess hustlers are often assumed to be skilled and are seen as a challenge.
