Bottom two, facing action line check (50NL)

[Kraada]

Villian here is running at 15/5/1.3 over ~300 hands. I'm running at around 26/12 at this point.

I was confused here because I'm not sure what he limps PF that calls a big raise that I beat (weirdly played AK, KQ?). With that AF I doubt he's raising a draw, and I need a commitment plan now . . .

Thoughts?

my first thought is that Villian is fos, i call here and check the turn most likely he will shut down, if he bets like 7 or 8 i fold. try to get a cheap showdown, no reason to go broke with bottom two
