A raise from the cut off to 8,000 was met with a 32,000 three-bet from the button. David Chicotsky then got involved by asking the button player how much he had left behind. When he found out it was 85,000 he four-bet to 65,000. It was enough to show he was committed and enough to get the button to fold pocket jacks face-up instantly after the cut off player had folded.
