Early day 1 blinds are 100-200, I started the hand with around 25k. 

Villain is young black kid. So far looks like a solid tag.

UTG limps,3 folds, Villain (HJ) limps, Hero (CO) limps with 22, BTN limps, SB completes, BB checks.

Flop: (1200)

Ax 2d 6d

Checks to me and I bet 800. BTN, SB, BB & UTG all call, HJ raises to 5k. He's got me covered. 

I'm not sure if he could ever limp aces there, but let's just consider it highly unlikely. 

What do?
