KK on low flop OOP vs. LAG

[DMoogle]

Villain appears to be a very solid LAG, although this is the first session I've played with him. His name is ship_the_donuts. He's 24%/19%/2.6/30% over 1.2k datamined hands. I saw him coldcall an TAG's UTG raise in MP w/ 64s earlier. In this hand, he tanked a while before checking the turn, and he insta-bet the river. I really think MHING. Thoughts?

you don't call this a "low flop," you call this a "[censored] this game i run so bad" flop

this is fine

Wow, you have to call this riverbet. You are folding a HUGE part of your range here if you fold this.

Good river fold, seems solid all around.

lol, well I wasn't really sure what to call it. It is a lot different from a flop like 2-3-7 or 8-8-2.

Yes, I am. But I think a huge part of my range is beaten here. The only thing I could see him having that I beat is a bluff with JT or some kind of 9, and maybe a JJ or TT that he decided to not reraise preflop (i.e. he switched gears), but even those he'd probably check behind on the river. This looks like it's a value bet from a strong hand far more often than it is a bluff or a value bet from a hand that I beat. My hand practically only beats a bluff.
