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?
