Villain is 45/19 over a small sample, no real reads, but he looks generally fishy. This is the first time he's been oop without initiative on the flop vs me, so no idea what his donking range is here. I'd imagine most people check here with a good jack or better by default so I think raising folds out a lot of air, gets me a free river and also Ks and Qs will usually give me the best hand and A's can be barelled pretty effectively.

I think I can bet the turn harder here for sure.

My question concerns the river and how much to be if there's any value here at all. I don't like shoving because he has no worse Qs here and mainly Jx which will fold to a shove or QJ, random overpairs that are taking a passive fish line.

Thoughts on bet/folding river for 17ish?
