Live 2/5 NL--Pocket 10s as an overpair

[VegasRunner]

It's my first hand at the table at the Ventian where they never make you post. I sit down with $200 and the villians have me covered.

I'm in middle position and see pocket tens. I raise to $20, the cutoff and the button call. After the rake, the pot is about $60.

The flop: 2 5 6 (rainbow)

I bet $60, cutoff folds, button raises me another $100. I have $120 behind.

Shove or fold?

I didn't like the situation, but considering how much was in there and the fact that it was my first hand at the table, I felt like I had to shove.
