With his puppy-dog eyes and trademark cowboy hat, 75-year-old Doyle Brunson is one of the most recognizable players on the professional poker circuit. This summer marks the 40th annual World Series of Poker (WSOP), and the Texas native has competed in all but two of them – more than anyone else in the event’s history – and racked up 10 championship bracelets, tied for second all-time.

Who else could describe who it was back in the days than Doyle.
