This is the most lost situation I've been in. Villian is a 20/18 TAG. We had history some history in 50NL. I think he's a tagfish. I have nitty stats but he likes to play back agaisnt me.

when he moves in, what's your stack? if its &gt;70 or so insta-fold.

[Colombo]

impossible to answer w/o stack sizes.

sorry, hero covers.

What is a better line here since turn is a fold?

[EddieRooo]

This is pretty standard, I wouldn't feel too bad about it. Plus you might just be paranoid that he's playing back at you.

I'd fire a 2nd barrel with the nut FD and two overs.
