basic wrestling style in which nearly all holds and tactics are permitted in both upright and ground wrestling. Rules usually forbid only actions that may injure an opponent, such as strangling, kicking, gouging, and hitting with a closed fist. The object is to force the opponent into a position in which both shoulders touch the ground at the same time. Formerly known as the Lancashire style in England, catch-as-catch-can became the most popular form of wrestling in Great Britain and the United States and, with slight modifications, was introduced into Olympic and international competition as freestyle wrestling (q.v.).
