  whiteshark: <Chiron> is a chess engine with support of both UCI and Winboard 2 protocols.

Development of <Chiron> started in the fall of 2002 and it has been under continuous development ever since.

When it debuted at the Italian Computer Chess Championship in June 2003, it was a rather weak Winboard engine with a playing strength of about 2100 Elo points.

Its strenght grew over the years, it started to arrive consistently second at the italian tournaments and reached good ratings in the various rating lists.

In 2006 support of UCI protocols was added. At the beginning of 2007, it had a rating of about 2700 and 2650 Elo points respectively on the CCRL and CEGT rating lists.

Starting from february 2009, having lost the source code of the latest development version and wanting to implement bitboards, it underwent a major rewrite. In November of the same year it won, with an old version, its first italian championship and won it again in 2010.

<Chiron> has been commercially released on October 9, 2011.

In these nine years Chiron has improved a lot thanks also to ideas found in strong open source engines, in computer chess forums and websites, etc. In particular I would like to thank Fabien Letouzey, Tord Romstad, Robert Hyatt, the Ippolit guys, Ed Schröder, Bruce Moreland, Ernst Heinz and many others.

Thanks to Miguel Ballicora, Eugene Nalimov and Daniel Shawul for the probing code of their tablebases/bitbases, to Pradu Kannan, Gerd Isenberg and Lasse Hansen for the magic bitboards, to "Sesse" and Stephan Vermeire for the CTG specifications, to Ilari Pihlajisto for cutechess-cli that I've been using since 2009 for testing Chiron with very fast games.

Thanks to all the people that tested Chiron in the past, among them Ciro Vignotto, Leo Dijksman, Olivier Deville, Günther Simon, Lars Hallerström, the testers of CEGT and CCRL and many others.

Thanks to Wilhelm Hudetz for the Chiron logo.

Finally, thanks to Salvo Spitaleri who has been the opening book author of Chiron since 2006.

Aug-04-14  mrandersson: Nice chess engine from what iv seen and heard from a club friend. The engine reaches quite fast depths and often gives nice lines.

Does take a bit longer than the top 3 engines at finding some puzzles thou.
