I would too put his range at TT+ (higher pairs more likely obviously) Possibly A9, a set or a flushdraw. I'm never folding in this situation. I don't think you need any pot odds, and the point where I'm folding this would be unrealistically deep stacked.

I think the problem with getting the exact equity is that you can't just put this hand through pokerstove. Some hands are more or less likely according to the action.
Tons of villains limp with quality hands at these limits because they fear just picking up the blinds more than they fear death.
