Fair to assume villain isn't likely to be a lag with this sample size, but he could still be tag. I've ran 9/6 after 100+ hands at some tables before but I'm quite loose on average. He has also 3bet once, so we can strip out KK+ from his range and at least a couple of combos of AK.

My first thought was that we should be piling money in to get all in on the river and I think that's fine. Villain can have:

3 combos TT that crush us
4 combos KT that crush us
16 combos KQ and KJ that will probably stack off
0-8 combos AK
Bunch of draws that will call a turn raise and may stack off on river

So we're way ahead of the majority of his stacking off range. He'll fold JJ/QQ to a raise probably.

If river is a brick or low club we can stack off comfortably. A non club Q or J should probably be a check back and 10x is a check back too.
