It wouldn't suprise me if Doyle, Amirillo, and Sailor were colluding somewhat. In those games there was always the threat of getting cheated, robbed, or worse so I am sure in some games they wanted to maximize whatever win they could get out of the room with. Probably nothing too blatent but I would guess there was some unsavoryness going on as some point.

As far as the big game I wouldn't think there would be much collusion. If you want some decent insight to the "big game" I would recommend reading "The Professor, The Banker, and The Suicide King". While that game is mostly about the games and matches with Andy Beal it does get into the "big game" and some of the stories behind it.
