Not sure about this line. Is this a check on the flop? It seems like I turned my hand into a bluff when I have some showdown value.

Then as soon as V calls my thought is he has an Ax hand, maybe KQ plays this way. But when V bets for what appears to be value on the river. I think I have to fold.

I would probably check the flop and bet the turn.

What if I check and he bets the turn?

You call and eval river.

You can also x back A3-A5s OTF that will protect your KK.

Are we really 3-banging A3s preflop? (I can see checking back with our weakest aces, just not sure about having them that weak.)

Depends on your strategy. Otb against a CO open I don't see anything wrong with it.

Flop bet is too big. I would check the flop back as the others have said.

Hand isn't strong enough to get value from other hands on the flop as your opponent will have a TON of aces. Plus you're IP so when you check flop it allows your opponent to bluff the turn and you have a great hand to call down with. If he checks then you can 100% go for value with KK on the turn and probably the river depending on the runout.
