Konstantin Puchkov: Konstantin Puchkov (born 1952) is a Russian poker player, horse trainer and horse breeder from Moscow.  He was the fourth Russian-born player to earn a World Series of Poker bracelet.  He is best known for having earned a World Series of Poker bracelet in his first World Series of Poker in the money finish (2010 World Series of Poker Event #31: H.O.R.S.E., $1,500 buy-in) and setting the record for most in the money finishes at one series during the 2012 World Series of Poker (11).

World Poker Tour bracelet: 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."

WSOP.com lists him as a resident of Boynton Beach, Florida, while Hendon mob claims he is from Orlando, Florida.  Wade made his first trip to Europe at the age of 26 in 2011 because of Black Friday, which had limited his options for play in the United States.

Poker Hall of Fame: The Poker Hall of Fame is the hall of fame of professional poker in the United States.  Founded in Las Vegas, it was created in 1979 by Benny Binion, the owner of the Horseshoe Casino, to preserve the names and legacies of the world's greatest poker players and to serve as a tourist attraction to his casino.  Binion was known for the creative ways in which he marketed his casino.  In 1949, he convinced Johnny Moss and Nick "The Greek" Dandolos to play high-stakes poker heads up where the public could watch them.  In 1970, he invited a group of poker players to compete in what would be the first World Series of Poker (WSOP).  When Harrah's Entertainment, now known as Caesars Entertainment, acquired the rights to the WSOP in 2004, it also assumed ownership of the Poker Hall of Fame.  Currently, membership in the Poker Hall of Fame is handled directly by the WSOP.

David Lukaszewski: David Lukaszewski (born 1970) is an American poker player.  He was a Poker Room Shift Manager at the Desert Diamond Casino who won a bracelet in the 2003 Casino Employees Championship event at the World Series of Poker.  The Casino Employees Championship event was the first time that Lukaszewski had played in a tournament with a buy-in greater than $50.  At the start of 2003, Lukaszewski set the modest goal of competing in a major poker tournament and at the last minute, he and several friends decided to drive to Las Vegas to play in the WSOP.  Lukaszewski won the entry to the event by winning a $65 single-table satellite at Binion's Horseshoe.  When the tournament reached the final three players, they started shooting Kamikaze's.  "We were all having such a great time, sitting around playing poker that I think we may have forgotten about the prize money and the bracelet."

Omaha hold 'em: Omaha hold 'em (also known as Omaha holdem or simply Omaha) is a community card poker game similar to Texas hold 'em, where each player is dealt four cards and must make his or her best hand using exactly two of them, plus exactly three of the five community cards.  The exact origin of the game is unknown, but casino executive Robert Turner first brought Omaha into a casino setting when he introduced the game to Bill Boyd, who offered it as a game at the Las Vegas Golden Nugget Casino (calling it "Nugget Hold'em").  Omaha uses a 52-card French deck.  Limit Omaha hold 'em 8-or-better is the "O" game featured in H.O.R.S.E.  Both limit Omaha/8 and pot limit Omaha high are featured in the 8-Game.

He has also had success at the 2008 World Series of Poker, where he has earned over $230,000 from four cashes.
