Ace-hi in blindwar

Villain is 23/19/3. Haven't seen him at 2/4 before but I've beat up on him at .5/1 HU once or twice.

It was a float but I felt I was ahead of his range on the turn. I bet that small planning to call a c/r. If he c/c turn I planned on betting big on any low river to drive out another ace.

As played, I think river is a call since my line looks so much like ace-hi. I don't like a push because I don't think he bets ace-hi that big here.

its way to reasonable that he plays 8x or quads this way that i cant call here. You're hand can very well be 5x (less likely) or (more likely) 8x that there is no way opp is going to get to fold that, although you could show up with 66-77 but would never consider folding the river if u called the turn.

This is actually pretty clear ISF theorem. You can show up with a 5 and an 8 much more than your opponent so its really stupid for him to bluff a lot here.

the only way u can call here is if u have a read that opp rarely makes this turn raise size unless he is bluffing.
