From the TDA rules 40: Action Out of Turn (OOT) A: Any action out of turn (check, call, or raise) is subject to penalty and is binding if action to the OOT player does not change. In no-limit and pot-limit games, there is a minimum amount that is required to be bet in order to open the action. In games with blinds, this amount is usually the amount of the big blind. Standard poker rules require that raises must be at least equal to the amount of the previous bet or raise.
