This Chess game was written by Leonid Liberman in 100% assembly over several years, is still in it's beta stages. Does have some minor bugs in it, but overall, very nicely written. Compared to all other chess games I've seen, this game is one of the fastest. (& hardest)

Documentation!

Leonid has also recently started to write his "chess game theory". The doc is not yet finished, but if you'd like to see what he has already, click here. This doc is mostly technical stuff, so, if you're not a programmer, you're not going to understand most of it. It describes the basics of chess game programming, the logic used in this game, and even has bits of source code for better understanding.

There are a few documents written by Leonid about the game.

Inevitable Mate Positions!

These are designed solely for the really dedicated ones... (or chess game programmers) These are basically the positions, from which, there WILL be a mate within several moves, so, if a chess game does not detect a mate, it's a bad game! Fortunately, this game detects them all! You can read more about these positions.

Illustration for logic...

This is a small program & source that displays a chess board on the screen and goes through every move for the white pieces... It's pretty cool to actually see how a chess game checks every possible move... read more about it here.
