tricky 2nd nut flush hand

[WhoIam]

Bodog $.5/1

Bodog doesn't support poker tracker or Bison's converter so I've done it manually. Sorry if it isn't perfect.

This is my 2nd orbit, no reads.

Hero is sb w/ $97 Q [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/heart.gif[/img]
4 limpers, hero complets, bb raises to 3
5 callers, pot is $18
flop 9 [img]/images/graemlins/heart.gif[/img] A [img]/images/graemlins/heart.gif[/img] 2 [img]/images/graemlins/spade.gif[/img]
Hero checks, BB ($138) bets $5.25, CO ($24) calls, Hero calls
pot = $34
*Should I have bet this out? BB looks to be making a weak continuation bet. It seems unlikely someone would have the K [img]/images/graemlins/heart.gif[/img] since I have the Q and J*
Turn 7 [img]/images/graemlins/heart.gif[/img]
*Jackpot. I checked with the intention of raising. I realize now that I was pretty much telegraphing my hand on the flop*
BB bets $7.25, CO goes all in ($16.25), Hero calls, BB calls
Pot = $79.50
*the CO going all-in and the BB calling makes me uneasy. It seems very possible that one of them has a K-high flush. If I had to guess, I would say that BB has a set or two pair. I have about $75 left, so I'm not committed. I probably should have raised here but the all-in threw me off*

Hero?
