Hi guys!

Pretty common spot I suppose, so even more reason to talk about it. Villain is unkown (only 4 hands).

I asked pokerjuice: I gave villain FI25%!2% preflop (after not 4betting) and for calling on the flop any A,oesd, wrap, gutter+pair and 2pair.
-> A+,T9+,QT,J:(T7+),(KK,QQ):(T7+),79T+

WIth that range he has a straight 28% of the time OTT and we have 23% against that, so no odds to call if we were sure he has it. I don't really see him betting 2pair or a set here too often or turning it into a bluff. Additionally, most oof the hands with a T he raises preflop prolly have a Q or 7 in it as well.

All things considered I would prolly fold here since he has very little bluffing hands in his range. Is this too nitty?
If villain was a standard straightforward player I'd be happier with the fold, but against unkowns there can always be spazz or some AJT, TJ9 or sth. In that case x/shoving would prolly be better to get AI vs those, since x/c turn, x/f river is super exploitable.
