SSHE Hand Quiz - Flop Play Q#10

[Fantell]

I had a question about one of the hand quizzes and I was wondering if I could get some help.

For Question #10 on the flop play section in SSHE. Here's the question:

"Three players limp to you, one off the button, with Q [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/club.gif[/img]. You raise. Both blinds and the three limpers call (12 small bets). The flop is J [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/diamond.gif[/img], giving you an overpair. Your opponents check to you and you .....

In the question they have you betting, at which point all hell breaks loose with a checkraise and a couple cold callers. My question is, why would you bet in the first place? I know you likely have the best hand currently, but you're incredibly vulnerable. You have one good out to a strong hand since the Q [img]/images/graemlins/diamond.gif[/img] puts a four-flush on the board. You also have two overcards that could fall on the board, not to mention any diamond. There's a small chance but someone could be playing a gutshot or an OESD as well.

Given all of this, why don't you wait for the turn? If you bet now, there's a decent chance you get checkraised by someone sandbaggin the PFR (granted this is less likely on such a scary board as many passive players might just check behind). Also, in a 6 way pot raised preflop I don't think you're getting a single person to fold either. Getting better than 12 to 1 just about everyone can call profitably against you. Plus, since you're on the button there's a good chance you'll just get checked to again on the turn robbing you of another opportunity to protect your hand.

If you think that your probability of getting bet into on the turn goes up at all, it seems like you make the bizarre check behind and then get aggressive if a blank rolls off on 4th street.

Am I just insane?
