V is a 6max reg who occasionally plays HU mostly to start tables. He gii to wide sometimes and can be really spewy/ overbluffing a lot. He likes to bluff catch as well.

It's a ante table so defending this hand in bb is ok-isch I guess. His cbet otf is 74, which I think is a bit to high. I think my hand is a little to weak to flat so I decided to x/r. Turn is std. River is where it gets interesting. I think it's a clear vbet since I have the nut kicker and he is calling with any 3, maybe looking me up with AA or K, even though I am blocking one of the aces. I think bet folding hurts but is the right play. 

What do you think guys?
