I would like to thank other computer chess enthusiasts for advices and help: Graham Banks, Ray Banks, Shaun Brewer, Charles Smith, Sarah Bird, Aser Huerga, H.G. Muller, Jim Ablett

Authors of various chess software I used

Odd Gunnar Malin made very useful adapters Wb2Uci and InBetween.

Remi Coulom created a wonderful tool Bayeselo. I use it to compute the rating lists, LOS figures and performances.

David J. Barnes created PGN Extract which I use to perform opening classification of the game database.

Gabriel Guillory created PgnScanner.

Eugene Nalimov and Andrew Kadatch constructed the "Nalimov Tablebases". Daniel Shawul created Scorpio bitbases. I also thank members of EGTB Online project for making those endgame tablebases freely available online.

Norm Pollock made handy tools called "40H PGN Utilities".

Opening books used in this tournament were created by Harry Schnapp and Chesslib.
