8/16 live AA multiway facing heavy flop action

[nepenthe]

Some reads first:

MP has a spaztastic tendency to bluff, and is also particularly aggressive on the flop. I've seen her bet a flop like 8 [img]/images/graemlins/heart.gif[/img]T [img]/images/graemlins/club.gif[/img]J [img]/images/graemlins/club.gif[/img] with Q [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img] after limping with it in LMP against 4 other opponents, and bluff a blank turn and river against a caller who showed a T. Basically, she bluffs a lot in seemingly hopeless situations. She is also very aggressive with TPNK type of hands esp. on the flop, but will slow down on later streets if raised.

Button isn't quite as bluffy as MP here, but is still quite lag pre and postflop, and I've noticed that he doesn't know or care to read hands and only plays his own. It's the kind of guy who says, "I have 2 pair, I raise!" even when an obvious flush and straight draw came in on the river and a passive tight straightforward guy donks into a multiway field. Very aggressive with draws as well.

No particular reads on UTG and BB, except they're loose, fairly passive, and overall good for the game.

I'm in EMP with A [img]/images/graemlins/diamond.gif[/img]A [img]/images/graemlins/heart.gif[/img]

UTG limps, I raise, MP coldcalls, Button calls, BB comes along.

Flop: 5 [img]/images/graemlins/club.gif[/img]T [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/heart.gif[/img]

UTG donks, I go ahead and raise, MP 3-bets, Button cold-caps, BB folds, UTG calls, I call two, MP calls.

At this point I'm concerned most with Button's coldcap. Although he's aggressive and plays only his own hands, he's not crazy enough to do this with middle pair. His range is 2 pair, set, TP, and maybe flush/straight/pair or combo thereof. UTG's call of the cap is slightly worrisome. I'm concerned least by MP's 3-bet, because she could easily do this with something like TP, middle pair or worse. I don't put her on TPTK because I've seen her raise and cap A9o preflop.

UTG checks. My play and plan for the rest of the hand? Bet-call (up to how many bets) or check (with the intention of calling/folding/raising - depending on what type of action?)
