23rd World Computer Chess Championship 2017, from July 03 to 07, 2017, Snellius Building [2] [3], Leiden University, Leiden, The Netherlands, in conjunction with the WCSC 2017, the Advances in Computer Games 15 conference [4], and the 20th Computer Olympiad [5].
Four participants played a triple round robin, time control 105 minutes per side plus 15 seconds increment per move (105+15). After nine rounds and two decisive games, first and third place required a play-off. First place and winner of the Shannon Trophy was again decided between Komodo and Jonny, third place between Shredder and Chiron. After two games with 2 x 45+15 and two further games with 2 x 20 + 10 time controls, all drawn Komodo won the last play-off of two games with 2 x 10 + 10 with White. Shredder became third after winning the second play-off pair.

A New Format
On June 07, 2017, a few weeks before the upcoming WCCC 2017, ICGA president David Levy announced a new format (excerpt) [8] [9] :
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. ...
