Maverick (TV series 1957-1962)

Bret and Bart Maverick (and in later seasons, their English cousin, Beau) are well dressed gamblers who migrate from town to town always looking for a good game. Poker (5 card draw) is their favorite but they've been known to play such odd card games as Three-toed Sloth on occasion. The show would occasionally feature both or all three Mavericks, but usually would rotate the central character from week to week. - IMDb
