Chess Software

There are many sorts of software developed for chess, which can be grouped into several categories.

Chess Databases

ChessDB is a free open-source chess database. ChessDB runs on Windows, Mac, Linux and UNIX systems. It is no longer developed, but is very functional. Here are notes on using chessdb.
Chessbase is a chess database for Microsoft windows. Unlike ChessDB, this is not free and is in fact quite expensive.

Chess Engines

Crafty developed by Professor Robert Hyatt is a free open-source chess engine. It has a very rudimentary text-based interface, but uses the so-called Winboard protocol. Hence you can use it with any interface which supports this protocol. Crafty is a strong chess engine, which can run on machines with multiple processors.

Chess Software for Pocket PC and Palm handheld device

There are numerous chess programs for Small handheld computers such as the HP iPAQ, Dell Axiom and Palm. There is a review of 63 such programs performed by Dr. Axel Schumacher. A summary of the results is available, or the full review which is just over 3 MB in size. First place was won by Pocket Grandmaster which is a commercial program. This is an excellent program. Second place was won by CE Board and third was given to Pocket Fritz 2. These are all for Pocket PC. The highest ranked device for Palm was Chessmaster

There are to my knowledge only two programs that allow you to connect to internet chess servers from a PDA. These are Intellichess and Thinkerboard. The web site for Intellichess looks very attractive, but the software is just about unusable. Thinkerboard is a little better, but is only alpha software, so it clearly not fully debugged. But Thinkerboard is the better of the two and has the advantage of being free.
