'''Guy McCrossan Haworth''',<br/>
a British computer scientist and lecturer at , now retired from the School of Systems Engineering <ref>[http://www.reading.ac.uk/sse/ School of Systems Engineering]</ref> , [https://en.wikipedia.org/wiki/University_of_Reading University of Reading]. Guy Haworth's research interests include the use of chess as a demonstration domain, and the [[Retrograde Analysis]] creation of [[Endgame Tablebases]]. He collaborated with [[Eugene Nalimov]], [[Christoph Wirth]], [[Peter Karrer]], [[John Tamplin]], [[Marc Bourzutschky]] and [[Eiko Bleicher]] on Investigations of [[Endgame Tablebases]] with Depth to Mate (DTM), Depth to Conversion (DTC), DTZ and DTZ50 metrics.Data on percentage-wins, maximal-DTx figures and positions, and [[Zugzwang|mutual zugzwangs]] have been filed and made available on the web, as have the DTM EGTs <ref>[http://chess.jaet.org/endings/ Chess Archives - Endgames (DTC, DTM, DTZ, DTZ-50)] hosted by [[John Tamplin]]</ref> . Since 2002, Guy has been demonstrating demonstrated 'Skilloscopy', i.e. methods of measuring the Skill of Fallible Decision Makers, by ranking chess players according to the quality of their moves in the full move-context of the positions in which those moves were played.Guy Haworth served as Vice-President of the [[ICGA]] from 2002 until 2005.
