So I'm anxious to work on my O/8 game, hence posting in HJ. Anyway, my question is on the turn, but comments up to there are also welcome:

Preflop (9 handed)
Hero has A [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/club.gif[/img] Q [img]/images/graemlins/club.gif[/img] T [img]/images/graemlins/diamond.gif[/img]

UTG calls, UTG+1 calls, MP1 calls, MP2 folds, Hero checks, CO calls, Button folds, SB folds, BB checks

Flop (6 players, 6.25 SB): T [img]/images/graemlins/club.gif[/img] 2 [img]/images/graemlins/diamond.gif[/img] A [img]/images/graemlins/spade.gif[/img]
BB checks, UTG checks, UTG+1 checks, MP1 bets, Hero calls, CO folds, BB calls, UTG calls, UTG+1 calls

Turn (5 players, 5.5ish BB): T [img]/images/graemlins/spade.gif[/img]
BB checks, UTG checks, UTG+1 checks, MP1 bets, Hero ???

So here's why I'm confused:
* If I call, I'll probably get a couple of callers. So the river will be 4-way for ~10BB; if a low card falls, though, it seems like I'm almost certainly chopping the pot (why else would people call the turn bet?) However, if a high card falls, I'm scooping, so the extra bets are good.
* If I raise, I'll probably chase out everyone but MP1, who may (a) be betting A2 or something, or (b) might have a low draw without counterfeit protection (so even if a low card comes, if it pairs his hand I'll still scoop). So if a low card comes, there's still a chance that I scoop; if a high card comes then I definitely scoop but it's a smaller pot.

So which is better? Sorry if this is a very basic question, but I'm still very new to this game.

[and a thread hi-jack in the OP!]
I have AAAQ in the SB, and there are 4 limpers. Do I complete? (Yes, the Q is sooted w/ one of my Aces)
