A couple more chess programs:
Chess C.4 by Michael Rakaska, TRS-80 Basic.
Published in the Dec. 1981 issue of Creative Computing magazine.
I have the source, but it makes heavy use of TRS-80 graphics and would take some work to port to anything else.
Modern Basic lovers might not like the many pages of very densely packed code - dense enough to give @bplus fits.
It was ported to other machines, although a quick search has not turned up the source for any of those ports.
Early in the PC era it was compiled and released for DOS as an .EXE file.
Rosetta Code lists a QBasic chess program by Dean Menezes (https://rosettacode.org/wiki/Chess_player) which compiles and runs under QB64PE. I've only done some quick testing, so I don't know how WELL it runs.
