Villain in this hand is on 3 or 4 of my tables, and during the first 20 or so minutes we were both being quite aggro, pretty much only preflop though. He's three bet me a bunch, to which I've mostly folded except for 1 successful 4-bet, but also one unsuccessful 4-bet where he shoved and I folded. I've also been active in squeezing and 3-betting vs him. We haven't seen a flop heads up though, only multiway in which he has played straight forward. Over the last 20 or 30 minutes though he's calmed down a lot and is hardly 3-betting, and is playing a lot more straight forward. This seemed like a spot where he was going to show up with a weak range, and I wanted to hear what you guys thought would maximize fold equity. Also, what do you make of the minraise.
