I've got everyone's favourite position here, out of position against a mildly aggressive and somewhat tight opponent, but probably aggressive enough to raise some draws and smaller made hands (AJ at least), with top pair aces with second kicker in a single raised pot as preflop aggressor. Supposedly basic, very common and very tricky in most people's opinions.
The turn is obviously either a check/fold or bet/fold (anyone want to argue for bet/fold?), so the flop play's the thing. We expect to be ahead when we reach the flop and probably still are slightly ahead of the raiser's range, but position works against us and further action is going to cut out all of his holdings we want to play against. Folding on the flop seems too weak, but is our positional and information disadvantage with multiple draws possible enough of a handicap to justify it?
EDIT: forgot the actual hand:
