Villain is 15/12/2.5 over ~200 hands (all from earlier sessions and I didnt have notes or didnt remember anything on him). I'd played like 10 hands and raised half of them at the table (might be a factor for his pf range?).

Hero? Any merit to a thin v-bet in this spot? Can't see any hands that have us beat that he wont bet either on the turn or river, and I'm almost 100% sure I wont get c/r like ever. Is these two factors enough to make a small river bet of ~1/2? Can we get a call from TT or even an unlikely 9, (AK)?
Cheers

You have the best hand like always unless he freaked out on the turn with AQ or KK+. I think he has exactly AK or TT here 80%+ of the time. Uh... yeah why not bet $14 or something.

I would check because it's hard to give an accurate range for him. But there are never more hands in his range that you beat and there might be more hands than you would think in his range that beat you. This guy looks pretty weak tight an can e.g. use AQ as bluffcatcher. So if you assign a very tight range it may be slightly +EV, but when you are wrong it's never gonna get better than that, but only worse.

Indeed it sounds a lot like AK/TT except if he's a tricky opponent. We may got some value from TT (I doubt from AK), and I'm enclined to VB around 8-9.

I'd say this is AK/TT maybe JJ or his light 3bet stuff.

I prefer checking than bettign cuz there's not rly obvious hands we can vbet. Say turn and river were reversed and queen came off on the turn then I'll prefer it but it is 3bet pot and I'd hate to get c/r river though unlikely.

If we check river though we gain important 3bet information.

+1 Ditto

I vb this all day, but I'm also prone to c/r this river (as villain) with a 7 or JT because I see a Q betting here often and I think I can get value from it or a slowplayed set.

Thanks for replies!
In retrospect I think this bet was too thin (also been talking to someone with way more knowledge).
Firstly, it's a rr pot and people (especially this type of villain) will tend to play way more carefully.
Secondly, there's one legitimate hand that we might get a call out of, and certainly not everytime (maybe in the 60% range?). AK pretty much never calls. In addition to the fact that we're beat here some amount of the time, it's just not +EV in my opinion.
Just posting results for a laugh, doesn't relly matter for the decisions (just shows that I gave him a way to narrow range); I bet 17, and he called with Q3cc. Funny how nits just turns totally spewy in some spots..
