My (former) bot;
I'm a bad programmer and was an even worse poker player at the time. It took me an awfully long time to make it profitable though, and if I went back to it I'm sure I might be able to make it smart enough to play .5/1 or 1/2. Not worth my time though, I decided to actually learn the game and find playing easier than programming AI.
This bot had no opponent modeling and played an ABC super tight full ring style. It's scary to think what a minimalist opponent modeling style could do.
