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) then, for a 64 bit computer,
you can download Queen 4.05x64, of 19 August 2022. It has built-in test positions, to be used as instructive exercises.
If you have a 32 bit computer, please download Queen 4.05c of 25 March 2021, instead of the above version.
Queen may play better in openings if you also use the separate (binary)
opening book (about 2 MB, zipped), based on files supplied by Carlos Pesce.
