Ok, so have some history with the bb, he begun by letting me take his blind every round from button, but he has been taking offence to it of late reshipping his 20 bb stack a few times... Now he just had a double up a few hands ago and I have a feeling he wants to play back at me this time around....
Is this ok to 4bet call or too spewy and I should just fold?
