NL200 - QQ multiway on connected board

[Burdzthewurd]

NL200 6-max

Stacks:

Hero (UTG): $450
Button : $51
SB: $275
BB: $149

BB had been steaming since he busto'd twice and rebought for a weird amount. Button is a shortstacker who has rebought once for $50, and is a little loose preflop, but only has put in money with good hands postflop. No read on SB.

Hero raises to $8 with Q[img]/images/graemlins/heart.gif[/img]Q[img]/images/graemlins/club.gif[/img], 2 folds, Button calls, SB calls, BB calls. Pot is $32

SB checks, BB bets $15, Hero raises to $42, Button goes all-in for $43, SB calls, BB calls, Hero calls. Pot is $204.

SB goes all-in, BB folds, Hero?

Obviously really sucks that I can't shove the flop due to the $1 raise. I was pretty alarmed by the SB cold-calling a bet and two raises though. Is this standard shove on turn? As played, hero fold on river? I can't imagine he just bluff-shoves or has some wacky hand like A8, right?
