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 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.
