Chess Engine v2
My old chess engine is a failure at chess so I decided to start over from scratch, this time using what I learned from my previous attempts.
Disclaimer: I do not use this or any other engine to cheat on chess.com. I'm a programmer, and I'm writing a chess engine.
The new engine now understands ALL chess rules (the old one didn't know about 3-fold repetition and had trouble with capture promotions). I switched from using square arrays to bit-boards and put some effort in to generating large, pre-calculated tables to speed up evaluation and move generation.
I had my new engine play my old engine in a 20 game match (each looking only 2 moves deep), and it got quite crazy. The new engine won 17-1-2. Here are a few of my favorites...

OK, that's enough of the tournament games. Here's a game I played against it (set to depth 2).
