I'm folding preflop

1.) T8s plays well multiway, and is often dominated HU/3way.

2.) I'm not sure why you think this guy is stealing. his PFR is highish, but not compared to his VPIP. In fact, the VPIP is high enough that it would take some specific encounters to assume he's sensitive enough to position to be trying to steal.

That being said, I lead out on the flop, and if raised i call and check/fold the turn UI.
