For Android users:
If you have an Android smart phone or tablet, please try my app
It is based on Queen, an older chess program of mine for Windows, see below.
Here is a video to clarify two new important commands that I recently added.
For Windows users:
If you like 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 Queen 4.05c, of 25 March 2021. This has an improved GUI, with a chessboard similar to that of my Android app Senior Chess.
It also has built-in test positions, to be used as instructive exercises.
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.
