Not much on villain, 26/21 after 19 hands. Pre and flop are fairly standard I think, turn I decide to continue as I have little SD, block two offsuit Kx villain can have, and can bluff on a river. And, other than FD, I don't have any obvious bluffs. River I feel like it isn't perfect for a bluff, as I have the Q, but I do still have blockers to villain's Kx, and I feel like villain will have folded most (if not all) Ax after the turn. How do you feel about a ~3/4 pot bet otr, trying to fold out flush draws and pp? Or an overbet?

If I'm bluffing this river, then I'm going with a larger polar sizing.

Not sure if an ob folds put any more than a 3/4 bet. I do like a third barrel. River couldn't be a better card to fire a third barrel.

Edit: not sure if I bet ott. Unsure what hands are folding outside of A highs. I think both are +ev, unsure which is higher tho.

I'm gonna say no. Ace is bad card for us. We have less AK combination now, block one club.
He can have A6 or A5 and more ace floats. Board is so dry I don't think we get lot of credit here considering even if we hit Ace on the river it would be more a x/c than a bet.

Think no clubs broadway hands should bluff rest give up.

ip should be flatting turn with a lot of A highs
if you bet river it's going to be an ob and you will rep trips+
since you're repping trips, he would need to fold a good amount of Ax at equilibrium, which is prob unlikely
that being said, as a pure exploit, you can bet small with prob all your whiffs and your better Ax and he's going to have a hard time defending enough mid/low pairs, Q highs
