One excerpt from the Kick Ass story I found interesting was the reasoning behind the initial decision not allowing him to play:
It seems to be not the presence of the second person / helper itself that's the
problem, even though that technically would violate the "one player to a hand"
rule, not to mention take up precious space in what already must be cramped
walkways between the tables. Instead, it may well be the communication of
information between the helper and Holbrook that has caused the WSOP to draw the line.
That was my initial thought when reading the story, was the "one player to a hand" rule and how it would be handled. I then began to wonder what douchebag would throw a shitfit and invoke the rule when he got busted by Jason. Guess we won't find out as Holbrook was eliminated in day 1. But to qualify for the tournament itself is an amazing feat.
