Did I play this bad?

Villain is likely calling JJ and Tx hands with spade, so I think we can value bet this river.

I agree mostly with imthenewfish's range of 66+,AJs+,KJs+,AJo+,KJo+ except that villain is under the gun, so I'd remove KJ, KQo and probably AJo, and replace them with small pairs, since I run at around 15/11 and I usually fold these hands utg. I'm much more likely to raise 22-55 utg than these broadway hands. Sometimes I think villain can have JTs too, and very rarely he has junk, again that's based on my game.

Flop is ok, I'd probably c/r hard but I don't mind donking pot size.

Turn c/c fine.

River I think there's value there, hands that crush us are betting the turn. We should know we're good, so why should we fear being raised? b/c river.
