Søren Riis,
a Danish mathematician at School of Electronic Engineering and Computer Science at Queen Mary, University of London, with a Ph.D. from University of Oxford. His research interests include mathematical logic, bounded arithmetic, computational complexity theory, representation theory and algebra, network coding, information theory, and theoretical aspects of computer chess. He used to play competitive chess in the 80s (Elo 2300) and has been briefly involved with chess programming ^[1]. He is moderator of the Rybka Forum ^[2], and critic of the ICGA decision concerning Rybka and Vasik Rajlich in 2011 ^{[3] [4]}, as manifested January 2012 in a ChessBase article with an immediate rebuttal followed by the ICGA ^[5].
