Thanks for your replies. I'm looking through my histories, and can see pretty easily where I went wrong on lots of individual hands. It's easy to do in reverse (knowing what the other guy had). Here's another one, which I just think is a bad beat. I definitely didn't have this guy on those rags. Maybe I wasn't aggressive enough. Let him draw out.
