Cash game, 4 players on the turn. First to act shoves, second to act folds, third to act calls, last guy folds. The guy who shoved gets mad because he says he thought that the caller had folded on the previous street. He said that because of where the cards were he thought it was a folded hand. The cards were in front of the player out on the betting line or maybe a little past it (I wasnt at the table) with no card protector. Does the betting line have anything to do with your cards?
