Clone Engine List

This is a partial list of Winboard/UCI chess engines that were proven to be unauthorized copies of legitimate engines. I may remove some clones that did not get distributed widely. I am not going to list fake “upgrade versions” of legitimate engines. There are too many clones to list them all, so I want to list those that fooled us long enough to play in a major tournament, or authors who released clones more than once. Many of the programmer names shown under 'Cloner' are not real, but some of them are. This list is intended to be an “avoid list”. I feel strongly that Winboard people should not play clone engines in any tournament! The only exception being the engines marked with an asterisk (*) indicating that the engine is no longer a clone.
