As played, I agree with this completely, just fast play multiway.

Now, if he'd three bet (correctly in my opinion) then there is sometimes merit to play a flop like this as normally we're WA/WB and we can represent 88, 99, 10-10, JJ or A-K and get more big bets in on the turn.

In a forum I can never justify cold calling a raise with A-A in limit hold em to a raise in early position. Situations arise very rarely that it might be correct but, it's SO opponent dependent AND takes a high level of experience to know when the play is correct that generally speaking it's bad advice. Especially if they're tilting! This makes them more likely to cold call three to the face. For balance? Just three bet occasionally with 8-9suited and that solves that problem.

I personally like to balance using aggression occasionally with mediocre hands than to use "trapping" with big ones in limit. In other words, I always raise with AA(full ring game) but, my opponents know(if they've been paying attention) that I'm also capable of doing it with 8-9s. In the long run I feel the advertising costs are close to the same and I feel like a raise is harder to "read by feel" than a cold call because games have gotten so aggressive these days. I do admit that I've never done any mathematical analysis on this and would love to hear the input/feedback from others about this approach.
