AKo BB - all-in guy messing things up

[Fiddler]

Hadn't played a lot of hands with these guys before this one came up. I'm pretty sure SB had been close to all-in a bit earlier and just bet/raised until everything was gone without much of a hand. The only read on the other villains, is that they are loose and will call-down with very little hoping to hit something. They also had no problem with betting into pf-raisers without much, stuff like MPNK on ace high boards. So loose when calling and over-aggressive when betting.

Preflop: Hero is BB with K[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/diamond.gif[/img].
UTG calls, MP calls, <font color="#666666">1 fold</font>, Button calls, <font color="#CC3333">SB raises</font>, <font color="#CC3333">Hero 3-bets</font>, UTG folds, MP calls, Button calls, <font color="#CC3333">SB caps</font>, Hero calls, MP calls, Button calls.

MP and Button calling here doesn't mean much from what I had seen.

Flop: (17 SB) 9[img]/images/graemlins/spade.gif[/img], 4[img]/images/graemlins/diamond.gif[/img], 6[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">SB bets $2 (All-In)</font>, <font color="#CC3333">Hero raises</font>, MP calls, Button calls.

Tried to get rid of them.

Turn: (12 BB) 6[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(4 players, 1 all-in)</font>
Hero checks, MP checks, Button checks.

All-in guy could be ahead of me and I just wasn't sure if I should continue here after both of the others called the flop raise. Didn't expect them to check it through.

River: (12 BB) 2[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(4 players, 1 all-in)</font>
<font color="#CC3333">Hero bets</font>, ...

Ideas or opinions on turn/river?

Why bet the river? A better hand never folds...

[Fiddler]

You sure they never fold? I thought I'd try to pick up the miniscule side-pot, maybe they would be worried enough about the all-in guy that they didn't think it would be worth putting in 1BB with T4s or something like that. Nah... you are right, they would call with any part. Bleh.

Do I want to show this hand down for 1BB if one of them bets? The board doesn't look very scary but I could be playing for only the side-pot.

Betting the river looks bad here. Like the above poster says a better hand won't fold and a worse hand will most likely fold.
