I'm my own worst enemy!? I think?

Villian checks, Hero bets 3000, Villian calls.

Turn: 6 [img]/images/graemlins/club.gif[/img]

To me, this play seemed fairly standard given the circumstances. Granted, the flop could hit a lot of hands, but I felt like I needed to bet there.

I haven't been playing much tourney poker lately, and just wanted a check-up on this hand. Thanks for the help.
