Chess,
a chess program by John Krause, written in 6502 machine language with versions for Commodore VIC-20 (with at least 8 KiB expansion), Commodore 64, Atari 8-bit and Apple II,
published and described in the Compute! December 1984 issue. The program was printed in Basic syntax with machine code in Data statements,
along with a leading read and poke loop, to read the data and store it as executable code in memory.
The program applies alpha-beta with a depth from two to six plies depending on level 1-5, and a material only evaluation
with {1,3,3,5,9} point values. An improved 8086 version of the program for the IBM PC was published a few months later [2].
