76o, bet this river?

[CostaRicaBill]

Only have a few hands with villian, but hasn't seemed to get out of line so far. I think this is a river bet/fold to raise, but just want to make sure. Comments on the rest of the hand appreciated as well.

Fold preflop -- I don't know what you're thinking defending with 76o.

Scariest board ever -- fold the flop.

You shouldn't have gotten to the river in the first place.

EDIT: You are playing 5/10?

[CostaRicaBill]

Yes, 5/10, and I'm well aware that I suck. I guess I'm going a little overboard defending my BB.
