Value bet river here?

[Yoshi63]

My read on SB was that he was blatently loose. I figured he couldn't have even J-rag, because he would have been raising that earlier. Once again, I didn't bet river because I wasn't prepared to do a bet-fold against such a loose-cannon player, but also didn't want to get check-raised out of $20.

Thoughts? (last hand I post today, I swear [img]/images/graemlins/wink.gif[/img])
