Chessnut,
a microcomputer chess program by Geoffrey Bulmer which participated at the European MCC 1981, the European MCC 1983 running on a modified Acorn Computer with a 6502 processor ^[1], and the WMCCC 1984 running on a Commodore 64, where it won the title of Amateur World Microcomputer Chess Champion by default ^[2]. An improved version of Chessnut was also commercially released in 1981 by Acornsoft as Atom Chess for the Acorn Atom ^[3].

Quotes

by Tony Harrington ^[4]:

There was the solitary amateur entry, Geoff Bulmer's 'Chessnut', a plucky little program running on a Commodore 64 and guaranteed of the best amateur trophy even of it didn't won a game (it didn't).
