Comments on this middle pair hand requested

[valejo]

This is fairly early in a large tournament.

I'm just now learning tournament play, so comments on all streets will be helpful. This isn't a hand I wanted to be involved in, but nobody was showing any strength so I thought I might nab it. I think I should have checked the river and folded to any bet.
