That is definitely too tight against a standard open, but this guy opens 4x. I'd like to have some info on this player to make a better decision. If he's a loose-spewy player who opens big very often then I'm just gonna jam here.

If I have a read that this guy is a nit who always opens big with 1010-QQ for example then I might be able to find a fold here.

I don't think flatting is ever an option. So many bad flops we are check folding since we're OOP. Against a standard 2x open I wouldn't be against flatting, but would probably be jamming here more than anything.

Did he opened 4x before ? If yes shove, if not muck :)

Mehh, kinda close.

More often then not 4x from weak tight fun player are hands they don`t want to see the flops with or let others suck out on them for cheap i.e 66-KK, AT-AK.

Considering this guy has been so passive its fine to fold, but dont make a habit of interpreting this sizing as top of their range exclusively.They`re still weaker players and will occasionally show up with some completely random stuff.

I guess you can find a fold here.
