"Good Raise" or "Raise"
The dealer claims to have heard "Raise" while he argues that he said "Good raise" to the button (indicating that he was folding).
The floor is called over and after talking with the dealer and two other people at the table that heard just plain "raise", he is forced to raise the minimum.
The button then makes a big move, shoving all in for 4,000.
The big blind then went into the tank for several minutes. It is unclear if he had a hand that warranted the tank, or was simply trying to punish the table for making him raise.
Eventually, he let go of his hand.
