iso his limps relentlessly when you're otb. - almost atc will do - depending on the blinds.
The fold-to-3b looks like a sample error, unless he's really only calling with AA.
You really want to be two seats to his left or right because he will let you have your blinds and not defend steals.
I wouldn't mess with such tight ranges too much. It looks like he's folding the nuts to any sort of agression, but it's a small sample.
