Poker is a game of skill. Reading the board is a skill. We, as TDs, should have no interest in helping players to hone those skills.
Nick, you have a point about chip dumping, but I don't feel that is a true problem here. Either players bet it all and have to flip up their hands, or one player folds to a bet. And technically any time a player bets and another player folds to that bet it could be chip dumping.
