"Frank" = Chip Leader
Cries of "Yeeaahhh!", "That's how we do it!" and "Ship it! quickly attracted the attention of the tournament directors looking to enforce the new extended celebration rule (aka the "Hevad Khan rule"), which prevents players from going too "over the top" when they win a pot.
On this occasion, the player was given only a warning as one of his opponent's was overheard to comment "That's the worst call I've seen in poker."
The player is now up to around 80,000 in chips - so who is he? Well we asked for his name, and he told us he simply wanted to be known as "Frank."
