I like raising on the turn because many times the opponent has already ruled out the possibility of you having an ace... the check-check on the flop makes it seem like both of you are wary of the Ace-high flop.

Then you get played back at by weak aces, KK, etc.

And if you don't raise the turn, then I feel that there is no way you can fold to any river card. There can be no second-guessing, because you asked for the push.

I play it both ways, and I think both lines are fine--- as long as you are committed to calling a river push if you chose to flat call the turn.
