TPGK facing strange river c/r

[shpanko]

Villain is like 23/18/2.5 from mostly data mined hands, though I've played with him a lot. He's a solid tag for sure but knows how to bluff in the right spots. Also I believe he knows I'm a good player (thus he knows I v-bet thin and check behind on turn for pot control with certain hands etc), we don't have a ton of history tangling but we've played a lot of hands at the same table in the past. Anyway what do you think of this river action?
