Well, if there"s no behind-the-scenes collusion going on, I"d be mighty surprised. When those people then do the moves that increase their chances of taking chips, that will be more readily seen by someone that can see the cards face up, than it can by the players. It"s not even like people living in the same town coincidentally. You can see instantly who has an interest in each other, especially with only 4 teams. Yes, it"s a team game, but telling each other your cards is not "just part of it". Of course, some might disagree, and have arguments for it. I doubt anyone will present them here though, will they?
