The biggest names in the online poker world are pledging their efforts to aid quake-riven Haiti.

Tonight’s “Play for Haiti” Tournament comes courtesy of Full Tilt, Pokerstars, Absolute Poker and Ultimate Bet (all of which are familiar, or should be, to online poker fans). These sites have committed to matching all player donations, offering a $5 buy-in and a $10,000 pool as incentive.

Absolute Poker andUltimate Bet are hosting the tournament, and CEO Paul Leggett sums up the aspirations: “Along with the rest of the world, we’ve watched the headlines and news unfold with growing horror as the magnitude of the devastation in Haiti has been revealed. We believe we have a duty to do what we can to help raise funds and awareness for the plight of the people of Haiti, and our ‘Play for Haiti’ tournament is one small way we can work with our players to contribute.”

“Play for Haiti” starts at 8:30pm EST tonight (Wednesday, January 20th). The $10,000 prize pool offers coveted entries to the $4 Million Ulitimate Bet Online Poker Championship tournament, with a $2,600 entry for first place, and a $1,050 entry for 2nd place. Everyone who places between third and ninth place gets a $215 buy-in for a 25 seat satellite, and 10th through 15th gets a $109 entry into a 100 seat Satellite.

All donations go to the Red Cross Haiti Disaster Relief Fund.
