Villain has only been here for 3 laps so read isn't that good. He has played 19% and seems pretty aggro postflop.

What the f-ck is going on here?!

Time to slow down on the turn - when he leads out after calling a cap on the flop odds are your 2 pair probably isn't good.

Well he had for no low and a J-high flush draw. I don't get it.

Considering it was HU on the turn, did I overplay it?

I feel like you did but if he's that bad, who can say. I suggest you mark this guy down as a major loose cannon....
