Easy fold of AA here, right?

[rikz]

Villain is 15% V$PIP, 7.2% PFR, 1.2 Total post flop aggression over 66 hands.

The best I can read this, his check raise is most likely a set of tens given his min-raise/call preflop, a big Ac-Kc/Qc/Jc flush draw, or an overpair like JJ or QQ? I suspect AA or KK would have either limp/reraised preflop or led out for more than a .5 raise, so they are unlikely hole cards for villain.

All this being said, easy fold here, right?

Hero has an easy fold here, right?

Was hero's preflop reraise big enough?

Was hero's flop bet too small at about 3/4 pot?

Thanks.
