NL25 Playing AA OOP against a tight player

[duke186]

Villain was running about 18/7/2.6

I assumed his limp range was pretty wide including both 33 and 55 as well as a bunch of 10x's. I feel like reraising the flop gives my hand away too much, and the min raise is sort of scary. What kind of line do people take here, bet the turn and call a shove?

Duke, as previously stated raise more preflop. 4x +1 for every limper. I know its Aces and you don't want to scare anyone away :P
