Computer Analysis of World Chess Champions 65
Computer Analysis of World Chess Champions 65 COMPUTER ANALYSIS OF WORLD CHESS CHAMPIONS1 Matej Guid2 and Ivan Bratko2 Ljubljana, Slovenia ABSTRACT Who is the best chess player of all time? Chess players are often interested in this question that has never been answered authoritatively, because it requires a comparison between chess players of different eras who never met across the board. In this contribution, we attempt to make such a comparison. It is based on the evaluation of the games played by the World Chess Champions in their championship matches. The evaluation is performed by the chess-playing program CRAFTY. For this purpose we slightly adapted CRAFTY. Our analysis takes into account the differences in players' styles to compensate the fact that calm positional players in their typical games have less chance to commit gross tactical errors than aggressive tactical players. Therefore, we designed a method to assess the difculty of positions. Some of the results of this computer analysis might be quite surprising. Overall, the results can be nicely interpreted by a chess expert. 1. INTRODUCTION Who is the best chess player of all time? This is a frequently posed and interesting question, to which there is no well founded, objective answer, because it requires a comparison between chess players of different eras who never met across the board. With the emergence of high-quality chess programs a possibility of such an objective comparison arises. However, so far computers were mostly used as a tool for statistical analysis of the players' results. Such statistical analyses often do neither reect the true strengths of the players, nor do they reect their quality of play. -

The Chairperson (Ms. Polgar) especially praised FIDE for the Women’s World Blitz and Rapid Championships in Saudi Arabia which had a substantially increased prize fund, though it was only one third of the prize in the Open section. The total prize fund in the Women’s championships were $250,000 for each event. Beatriz Marinello reported on her project “Smart Girl” on behalf of the Social Action commission, which included projects in Uganda, Chile, France and the US. This projects seeks to increase participation by girls in chess in those countries. Martha Fierro elaborated on the project about chess in women prisons in Genoa, Italy, which involved the training of refugees in Italy who in turn, train women prisoners. Sophia Rohde from the United States shared some of the work their federation is in doing to promote chess for girls in the USA. They subsequently presented a video showing various interviews with young girls in chess, highlighting the benefits and challenges that they experience in chess. -
1999/6 Layout
Virginia Chess Newsletter 1999 - #6 1 The Chesapeake Challenge Cup is a rotating club team trophy that grew out of an informal rivalry between two Maryland clubs a couple years ago. Since Chesapeake then the competition has opened up and the Arlington Chess Club captured the cup from the Fort Meade Chess Armory on October 15, 1999, defeating the 1 1 Challenge Cup erstwhile cup holders 6 ⁄2-5 ⁄2. The format for the Chesapeake Cup is still evolving but in principle the idea is that a defense should occur about once every six months, and any team from the “Chesapeake Bay drainage basin” is eligible to issue a challenge. “Choosing the challenger is a rather informal process,” explained Kurt Eschbach, one of the Chesapeake Cup's founding fathers. “Whoever speaks up first with a credible bid gets to challenge, except that we will give preference to a club that has never played for the Cup over one that has already played.” To further encourage broad participation, the match format calls for each team to field players of varying strength. The basic formula stipulates a 12-board match between teams composed of two Masters (no limit), two Expert, and two each from classes A, B, C & D. The defending team hosts the match and plays White on odd-numbered boards. It is possible that a particular challenge could include additional type boards (juniors, seniors, women, etc) by mutual agreement between the clubs. Clubs interested in coming to Arlington around April, 2000 to try to wrest away the Chesapeake Cup should call Dan Fuson at (703) 532-0192 or write him at 2834 Rosemary Ln, Falls Church VA 22042. -
