KK deep, 3b pot

First, I recommend remove the outcome of the hand next time or put them in to a spoiler.
The river seems like an easy check/fold spot. I’m not sure you will let an unknown fold a decent flush I and I wouldn’t be surprised he would only bet with better hands as well.

I understand you try to let him fold a better hand. However, most people will call off with a third card flush IMO. I think we just had to call that one.

His river sizing is indeed small. I missed that first, but even then, it’s tough to set him on a worse hand.

Pre I think you could squeeze bigger. You are OOP vs both villains. I think about 1.40$ would be better?
The flop is quite dry so I don't think you have to bet that big.

What he calls the turn with? QQ, KK (split), AJ, flush and FD+pair? It means that pretty much all of his hands just improved OTR. When you check the river, I think it very much looks like you don't have a strong hand -> therefore he is making a very very small bet to squeeze max value out of you. I don't see any reason to shove there.

If I was villain I would think that your river check showed weakness, you could be induced by the very small bet size and you probably wouldn't raise shove any weaker value hands than nuts. And what K♥: hands you will sqz and then dbl barrel when AhKh is blocked? KhQh is imo only reasonable hand you have there and I'm not sure villain is gonna fold his third nuts because you have 1 possible combo that beats him.

River is definitely a xf. Look at the board. If villain is ready to fold something he will not bet.
