This gets more interesting after watching the video again. I have a Question regarding the BB. When he said " you're going to limp, I'm going to raise, and you're going to call." Would you have held the BB to his out of turn verbal declaration, (as stated in rule #29 Verbal Declarations/Acting in turn) if he checked after the SB called? I think this is a perfect example of why this ruling was created, to stop this type of table chatter.
Here is the TDA ruling #29 Verbal Declarations/Acting in Turn
Verbal declarations in turn are binding. Players are required to act in turn. Action out of turn will be binding if the action to that player has not changed. A check, call or fold is not considered action changing.
The way I understand this rule, the only action that was not defined that would have changed the action , would have been a raise by the SB. In that case, the out of turn verbal declaration by the BB could be retracted and not enforced.
Both players were guilty of violations of rules. That's what makes all of this interesting and worthy of debate.
