Scary (or stupid) set of 6's hand.

[hfrog355]

We're about 4 handed at a 1/2 game and I'm sitting on about $80 when this hand comes up.

I find 6-6 in the SB.

Folds around to me and I raise to $10. BB calls.

Flop: K-J-6 with 2 clubs.

I bet $15. Call.

Turn: 8x

I bet $20. Call.

River: 10x

I check (is this a mistake?). BB bets $30

I think it over for a while, but finally call. I'll post results later, but what do y'all (yes, I'm from Texas) think?
