I figure thats a 44:1 shot on the river. I think I played the hand pretty well, and I was obviously miles ahead from the flop. I just can't get the hand out of my mind though. And am thinking about giving poker a break for a while. Any suggestions?

Sorry about the layout, it was in a B&amp;M so had I'm not totally sure on the exact stacks or anything. But I must replayed this hand a thousand times in my mind, so I'm pretty sure of everything else.
