Man, that reeks of a bluff. No other postflop reads? Any showdowns by villain?

Other than thinking that maybe he got there with 77, 99 or K9, or snuck in with KK, it just looks like a bluff. All he'd have to reasonably fear is a set or AK, because anything less probably couldn't call that shove.

I dunno, it's possible he has a draw like 8-10. He could also have 2 pair here, K9, 97. I'm thinking more like K10.
I probably call TBH.

I think here i would fold to early in a tourny to make this call.
