The long-time feuding poker pros will play as many as 25,000 hands of $200/$400 No-Limit Hold’em. They’re playing all but the first 200 hands on the WSOP.com poker site in Nevada.

On Friday, they began the online portion of the challenge, and played for almost exactly two hours. Playing two tables at a time, the poker pros completed 424 hands during the session for a total of 624 hands overall. Negreanu opened the match with a $116,500 victory Wednesday at the PokerGo Studio in Las Vegas.
