For Windows users:
If you lime to play chess against the computer or if you are interested in matches between chess programs (with a WinBoard or UCI interface),
you can download the following executable program:
Download Queen 4.03a.
Queen will play much better in openings if you also use the separate (binary)
opening book (about 2 MB, zipped), based on files supplied by Carlos Pesce.
Special engine version (WinBoard/UCI)
If you want to use Queen only for machine-machine games (using the WinBoard or UCI protocol)
and you encounter any problems with the above general version due to Queen's
graphical user interface, please use Queen402Eng, which is merely a chess engine, without a GUI.
For more information, download the files readme.txt and queen.txt.
For Android users:
If you have an Android smart phone or tablet, you may try my app Senior Chess, based on Queen.
To show Senior Chess in action, I made an animation video.
