I think the problem is that you're crediting villain with doing this with mostly strong value hands. This is rarely the case in my experience and you've also noted that villain slow plays post-flop, which will almost always extend to pre-flop. Therefore I should think his range isn't particularly strong, but table dynamic will be most important here if you've not seen villain do this before.

My best guess against this guy and randoms would be {JJ-22, AJ-A7} and we can get it in pretty wide versus this range profitably with {22+,A9s+,ATo+}, which isn't far off our range for getting it in versus a short-stacker.

That said, against a random doing this after just joining a session, I'll only get it in with {99+, AQ+} the first time and widen to {22+, A9s+, ATo+} if he does it 2+ times quickly.
