 * Home * Engines * Shy**

a mainframe chess program by Juha Kasanen, Mika Korhonen and Timo Saari, written in Algol. Shy played the WCCC 1983 in [|New York], where it ran on a [|Burroughs B7800/B7900] at computing center, University of Helsinki, a [|mainframe] using [|stack machine] instruction sets with dense instruction syllables and 48-bit data words, optimized for running Algol extremely well, using simple compilers. The program is mentioned in the WCCC booklet with 30 KiB code size using 60 KiB of data, searching about 350 nodes per second. Shy drew from Patsoc, lost versus CHAOS, Bobby and Phoenix, and won from Sfinks. According to postings in rgcc, Shy and the Austrian Merlin were based on the Pascal source of Chess 0.5 by Larry Atkin and Peter W. Frey as published 1978 in Byte Magazine.
