Context: Samuel "Sam" Stein (born January 11, 1988) is an American professional poker player from Los Angeles who lives in Henderson, Nevada.  He won his first World Series of Poker bracelet at the 2011 World Series of Poker where he made two final tables and three in the money finishes.  In both the 2010 and 2011 World Series of Poker, he finished in the money in two $10,000 Championship events, with one of them being the Pot Limit Texas hold 'em championship event each year.  Of his nine World Series of Poker (WSOP) cashes, his last five are in pot limit events. The World Poker Tour bracelet is the World Poker Tour's (WPT) answer to the World Series of Poker (WSOP) bracelet.  Beginning in 1976, the WSOP started awarding bracelets to winners of WSOP events.  The WSOP bracelet has become synonymous with greatness.  "It's impossible to overstate the value of a World Series of Poker gold bracelet to anyone who takes the game seriously," stated World Series of Poker Commissioner Jeffrey Pollack during the 2006 bracelet unveiling.  "It is the equivalent of winning the Stanley Cup in hockey or the Lombardi Trophy in football."  Since their introduction, a poker player's success has been measured by the number of bracelets they had won.  With introduction of the WPT bracelet, the WPT hopes to capitalize on the prestige of winning poker bracelets.  WPT Founder, President and CEO, Steve Lipscomb said, "The championship bracelet has become synonymous with poker as a symbol of achievement and respect, and we are honored to continue the tradition that Benny Binion [the founder of the WSOP] began over 30 years ago."
