The winner of the Main Event has traditionally been given the unofficial title of World Champion. However, some believe that no-limit hold 'em is not the optimal structure for determining a champion poker player. In 2002, Daniel Negreanu argued that the Main Event should switch to pot-limit hold 'em, believing that pot-limit required a more complete set of poker skills than no-limit, although he admitted that such a change would likely never be made. However, after the $50,000 H.O.R.S.E./Poker Players Championship event was added, many of the game's top professionals, including Negreanu, have since stated that this tournament ultimately decides the world's best player. The $50,000 buy-in, being five times larger than the buy-in for the Main Event, has thus far tended to deter amateurs from playing in this event, and the variety of games played require a broader knowledge of poker. The first $50,000 event, conducted as a H.O.R.S.E. tournament, was won by Chip Reese in 2006. In 2010, the $50,000 event changed from H.O.R.S.E. to an "8-game" format, adding no-limit hold 'em, pot-limit Omaha, and 2–7 triple draw to the mix, and was rechristened The Poker Players Championship, with Michael Mizrachi winning the first edition of the revamped event. Since Reese's death in December 2007, the winner of this event receives the David 'Chip' Reese Memorial Trophy in addition to the bracelet and the prize money.
