Go up one level in this thread


Hello Christophe, thanks for your message !
I know pretty well Lang’s Genius 3 and Genius 4, they are quite strong chess
programs...
The ZX  chess programs that seem to have implemented that ‘PV- trick’ are:

Colossus 4.0     author    Martin Bryant  1986 (shows nodes, depth, best line,
current line)
Superchess 3.0  author    Chris Whittington  1983 (shows nodes, best move)
Superchess 3.5  author    Chris  Whittington  1985 (shows plymax, best line)
Cyrus 48k          author     Richard Lang  1983 (shows nothing)

PS: Last year I saw two games between Superchess 3.0 (maximum level, about 15
minutes/move on ZX machine) and Rebel Decade (2 seconds/move on P120Mz machine).
Superchess lost both...

Thanks again,
Cristian
