The villain is a 21/17 reg who has spazzed out against me and bluffed with total air against me in random spots. He tends to call 3 bets a little too lightly as well as a side note. Also in 2.7k hands hes down 25 BB not sure if that necessarily indicates he a losing player but take it fwiw. My question is, is there more value in betting or check/calling? Before I bet the river I was struggling to see what hands will call me that I beat besides AT and possibly AK or AQ but I think that is a fold honestly if I shove. Perhaps I could have bet folded like 20 on the river but I would hate to bet fold this hand after there is so much in the pot. Usually top two is a totally standard shove but I was reluctant in this hand for some reason, need some help please.

turn raise is probably bad, im guessing you're bluffing close to 0% of the time and anyone decent knows it.

can you elaborate on why its bad? Not that I don't agree but clarify a little bit more. Are you never raising this turn with any part of your range?

yeah not too much of a turn raise, dont think we are doing it with bluffs all that often, so he folds alot that may fire a 3rd on the river which we can raise as were IP.

not sure what you expect him to call on the river other than maybe AT/A3?

Were not IP

Agree on turn raise being pretty meh.
With your read of villain I would never bet/fold here, your range does not contain many flushes given action and according to you he is somewhat spazzy.
It's an awkward spot, but think c/fold is all you can do here. Don't really see him turning made hands into bluffs too often (even though he probably should) and he doesn't have air almost ever on the river. Top 2 is nice and all but given action ur hand is somewhat overrepped and all replies assume that this line means very few bluffs.

Yea I guess I see why I overplayed my hand a bit. I just felt like the way the game flow was going, he was capable of calling with hands like AQ or AK with which I wanted to get value out of but once I got to the river I was totally stuck. So check call the turn seems to be the general consensus. But what if I check call and the river is a blank. What is my best play and why?

I actually don't mind donking the turn with this hand. You can build a pretty decent range around it, it's slightly less awkward than a c/r, and prevents him from checking back.

i like donking turn also, his calling range is a lot wider than his betting range.
also bet river then
donk/call turn but im not sure about river. if he's somewhat spazzy then call river too

3bet pre if he's calling 3bets too light. Also 3bet pre would be my default if he steals a lot from then CO (maybe he isn't if his overall stats are 21/17).

You can't raise this turn and value-bet a blank river with the reason beeing that you both have all 16 combos of KQ in your ranges. You are basically value-towning yourself with this line.

Well said, it is a much better spot to lead turn then to ch/r if anything.
