$50 Hand reading ftw? AK in RR pot.

[Chargers In 07]

Villain in this hand is 12/10/4 over just 40 hands though so enough to know he's aggro and not stupid.

wtf just calls this flop? I'm not saying I should fold here at any point but against a competent player what that I beat is calling here given my preflop raise size?
