Interesting 1000 PL Turn decision.....what is your play?

[ShortySaurus]

Hero is BB with K [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/spade.gif[/img] and $2141

Folded to loose button who limps ($801.25), SB completes ($1234), Hero raises 30, Button calls, SB calls.

3 to flop
Q [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/club.gif[/img]

SB checks, Hero bets pot of 117, button calls, SB calls.

SB checks, Hero .....?????

Is checking way too weak tight? If bet, how much? Theres no way you are folding to raise in this spot...who bets pot? who bets half the pot?
