The World Computer Chess Championship (WCCC) is an annual event organized by the ICGA, where computer chess engines compete against each other.

=History= The World Computer Chess Championship was created and organized by David Levy, Ben Mittman and Monroe Newborn in 1974, as suggested by the Soviet programmers of Kaissa :

Since 1972 (1970 Editor) in the USA and Canada were hold the yearly championships of North America among the chess programs, organized by the ACM. The team of Kaissa directed the organizers of these tournaments to the thought to conduct a world championship, whose organization within the framework its regular congress took upon itself.

=ICCA= Since 1977 the WCCC was organized by the ICCA, which was founded 1977 in Toronto.

=Shannon Trophy= The Champion is awarded by the Shannon Trophy.

= Hardware Limit= In 2009, ICGA president David Levy surprised potential participants of the WCCC 2009 with an disputed short term decision, an 8-cores hardware limit, a topic heavily discussed in various CC forums. As a consequence, the ICGA initiated an opinion formation related to that issue with respect to future World Computer Chess Championships.

= World Chess Software Championship= In September 2009, the ICGA announced following decision : As a result of this input from the participants the ICGA has decided upon the following for the 2010 WCCC and subsequent years:
 * 1) The World Computer Chess Championship for the Shannon Trophy will be contested by teams who have no Restriction placed on them as to their choice of hardware.
 * 2) A new tournament will be introduced called the "World Chess Software Championship" to be held at the same location and during the same period as the WCCC. This will be a uniform platform event using computers loaned by the host organisation. In each game played in this tournament the two computers will be, so far as is possible, identical with respect to their hardware capabilities: number of cores, processor speed, memory size.
 * 3) Participants may compete in either or both of these tournaments for a single entry fee.
 * 4) The time control for the WCCC will be such as to aim for a 4-hour playing session, namely all moves in 1 hour 45 minutes plus an increment of 15 seconds per move.
 * 5) The time limit for the WCSC will be such as to aim for a 2-hour playing session, namely all moves in 45 minutes plus an increment of 15 seconds per move.
 * 6) The WCCC will be an 11-round Swiss System event if there are more than 12 entries, otherwise an all-play-all event.
 * 7) The number of rounds for the WCSC will be decided according to the number of entries in both events but there will be at least 9 rounds in the WCSC.
 * 8) There will as usual be a rest day for an excursion and time set aside for the speed championship.

= Rybka Disqualification 2011= In June 2011, the ICGA has disqualified and banned Rybka and its programmer Vasik Rajlich from previous and future World Computer Chess Championships. The ICGA accuses Rajlich of plagiarizing two other programs, Crafty and Fruit, and demands that he returns the trophies and prize money of the World Computer Chess Championships in 2007, 2008, 2009 and 2010, see ICGA Investigations.

= A New Format 2017= On June 07, 2017, a few weeks before the upcoming WCCC 2017 in Leiden, ICGA president David Levy announced a new format (excerpt)  : Starting in 2018 the World Computer Chess Championship will be played as a match, between the reigning World Champion and a challenger chosen by a process which will be discussed amongst the ICGA Board and participants from recent years’ championships. That discussion will commence very soon after this year’s World Championship, which is taking place in Leiden from July 3rd-7th. This new format is akin to the FIDE World Championship (for human Chess players).

For the 2017 World Computer Chess Championship we are changing the format, removing the entry fee, and offering an expenses budget to each of the contestants. Our aim for 2017 will be to attract the strongest participants. There will be only 4 contestants, each of whom will receive 1,000 Euro for their expenses from the ICGA. The Komodo team have already indicated their acceptance, and we very much hope that some of the former World Champions and other leading programs will now find the event attractive and apply to participate.
