The following links are all somehow related to Draughts or the Deep Brew project:

• Basic Checkers: The First 20 Moves Intro to openings by Richard L Fortman
• Bob Newell's Site, lots of draughts info, including reviews of many Draughts programs and online play sites
• Checkers and Draughts Programs, Jean-Bernard Alemanni's index of draughts-playing software
• Chinook, the first World Man-Machine Champion (but note that programs like Kings Row and Cake++ are probably now stronger than Chinook was)
• Diagram Generator, the utility I've been using to generate diagrams for Move Over - one day this will for the basis of a web-based play vs. Deep Brew site
• English Draughts Association, the Official Website of the EDA; including news, events and some openings analysis.
• h4ns - information about learning and playing checkers
• Jim Loy's Checkers Pages, with lots of great information about the game, as well as interesting (and funny) detours.
• KCheckers, draughts-playing application for KDE.
• Martin Fierz's checkers pages , home to CheckerBoard, an interface with an open API for Windows, and Cake, Martin's very strong draughts engine.
• Open Checkers Archive, a large (and free) collection of draughts games.
• PDN Specification, A. Millet's checkers-oriented adaptation of PGN
• xcheckers, draughts-playing interface for X Window systems.

These links are very sparse. Email me with any links that you think would be useful to have here.
