Oh dear. He has an overpair. Does he have TT/JJ or KK/AA? I think you probably have neutral EV here - this is usually such a straightforward play that you want to think about how he's played premium hands before, has he done any flop bluffing - oh! Stop! Hammerzeit! He has a 5.5 post-flop aggression factor? I am pushing this motherfucker (sorry, I read his PFAF as 1.5 initially) - I think he has AQ, AK often enough and feels, as PF 3-bettor, that he needs to take the pot down whatever happens.

Either 3-bet or call and push any turn <Q.

Are many 25NLers 3-betting lighter than QQ+/AK? This line looks like AA/KK to me. But a 5.5 pfa is really high. How many hands? If it's over 200+, this guy must be bluffing a ton, so I'm calling and hoping he fires again on a non-A/K turn. If the sample size is small I prob call and re-evaluate turn, folding to a strong lead.

This may be nitty but I say just fold.
I'm not just going to go this guy has TT+, it's pretty obvious his range is heavily weighted towards AA.
I'll take a 4 to 1 bet right now that he has AA. That's right, if he doesn't have AA i'll give u $4 to your $1. Any takers?

This is just too smelly of AA. I don't mind calling here and seeing if he'll give u a lot of cheapness, which kinda seems like he wants to do.
