That AA hand is always gonna be hard to play correctly. The reason being that, you don't have many hands on him (no reads), villian may put you on a wide PF range due to your position, the low flop means he'll still want to play big pairs, he could c/r w/flush draw. But, you know all that.
It's a tough spot any way I think about it. Folding to an unkown c/r might be better than shoving. Seems weak, though. Where are the FTR regs?
