Courage or folly?

[AtticusFinch]

This hand is actually from a multi, but it was the first hand, so there are no significant strategy differences from a SNG. Blinds 15/30, 1500 chips total. I'm UTG with TT. I decide to limp and go for set/overpair value. 4 others limp ahead of me, then the CO raises to 200. My thought: "Overbet. A clear steal. He doesn't want callers."

The BB thinks for a LONG time, then calls. My thought: "Good hand, but not a big pair or he'd have reraised."

I push.
