benny,

As standard I fold this. But with your read on button, a c/r AI on the turn might not be bad, since he will have a tendency to call with weaker T's and maybe even a lesser PPs. I'm not sure about this line though, because your read on previous hands said he was CALLING big bets with trash - here's he's being aggro himself. I know that if he's a big donk it might not be a huge difference, but it should be something you should factor in when deciding to push/fold turn.
Btw, I like a turn lead in this spot.
