And what if five players in a tournament were to see a flop, the first player folds, the second player folds, the third player folds, the fourth player folds, and the fifth player takes the pot.
If it's okay for one player to fold with no action to him, shouldn't it be okay for everyone to fold with no action to them?
If you warn or penalize any of the four players who folded in this hypothetical, shouldn't they all be warned or penalized?
