given his VPIP, im really not sure what his hand could be? him c/c flop and turn makes me think he doesnt have a 3... maybe a 2?so A2 maybe?
Im such a donk, would appreciate some insight.

Given his VP$IP, you have to give him credit for a 2 or a 3, especially the way he's played the hand. Unless you've watched him play this way before and didn't have it, or he does it often, I'd say it's a pretty easy fold.

And I disagree with you. Him check/call the flop is exactly why I think he has a 3. If he has a 2, he's more likely to bet, but if he has a 3, he's more likely to let you bet as you're not likely to call with a 2 if he raises you.

Considering his VP$IP you putting him on A2 is way too tight.

He could have anything. Hands like 24 93 53 T3 J3 K3 Q3 23 etc. All which beat you.

58% of his hands means he plays more than 1 in 2 hands. Why would you put him on A2?

Against a player like this, you want a flop like J48 and you want him to be holding J2 or J6 where you're holding AJ. You don't really want a confrontation with him on a board like this.
