These are DOS programs but run smoothly under Windows too. My strongest chess playing program so far. Here is source code. A program playing chess variant Los Alamos on 6x6 board. A program playing chess variant on 4x8 board.
Pieces change to random type when they move.
Suitable for beginners. Nero doesn't attack all the time like public prosecutor. It has more humanity than ordinary chess programs. Good in finding mates. In this game two players fight by throwing each other with rusty hand grenades.
