That was a horrible horrible river. On the turn I put my opponent on a weaker straight, but I put him exactly on a lone ten. I have no idea why I pushed that river -- I guess I was worried that he would check behind. I mean I thought it was possible he was on a redraw, and there's the sick possibility he misplayed a set and filled up, but I was getting tired of a bad session and just bet out.

God I suck.
