get it in on the flop

If he only raises AAxx shouldn't we be able to get away from this? I'm sure the games Ribbo plays in some guys might play it cautiously postflop, but in my limited experience at low-limits if someone only raises AAxx preflop, they try to jam it all-in on the flop regardless of what comes.
