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. -

— I Believe Hostage the Most Interesting, Exciting Variant That Can Be Played with a Standard Chess Set. Mating Attacks Are the Norm
— I believe Hostage the most interesting, exciting variant that can be played with a standard chess set. Mating attacks are the norm. Anyone can hope to discover new principles and opening lines. Grandmaster Larry Kaufman 2008 World Senior Chess Champion — Fascinating, exciting, extremely entertaining—–what a wonder- ful new game! Grandmaster Kevin Spraggett Chess World Championship Candidate — Probably the most remarkable chess variant of the last fi ft y years. Captured men are hostages that can be exchanged. Play is rarely less than exciting, sometimes with several reversals of fortune. Dramatic mates are the rule, not the exception. D.B.Pritchard author of “Th e Encyclopedia of Chess Variants” — Chess is not yet played out, but it is no longer possible to perform at a high level without a detailed knowledge of openings. In Hostage Chess creativity and imagination fl ourish, and fun returns. Peter Coast Scottish Chess Champion — With only a few rule changes, Hostage Chess creates a marvelously exciting variant on the classical game. Lawrence Day International Chess Master — Every bit as intriguing as standard chess. Beautiful roads keep branching off in all directions, and sharp eyed beginners sometimes roll right over the experts.

Monarch Assurance International Open Chess
Isle of Man (IoM) Open The event of 2016 definitely got the Isle of Man back on the international chess map! Isle of Man (IoM) Open has been played under three different labels: Monarch Assurance International Open Chess Tournament at the Cherry Orchard Hotel (1st-10th), later Ocean Castle Hotel (11th-16th), always in Port Erin (1993 – 2007, in total 16 annual editions) PokerStars Isle of Man International (2014 & 15) in the Royal Hall at the Villa Marina in Douglas Chess.com Isle of Man International (since 2016) in the Royal Hall at the Villa Marina in Douglas The Isle of Man is a self-governing Crown dependency in the Irish Sea between England and Northern Ireland. The island has been inhabited since before 6500 BC. In the 9th century, Norsemen established the Kingdom of the Isles. Magnus III, King of Norway, was also known as King of Mann and the Isles between 1099 and 1103. In 1266, the island became part of Scotland and came under the feudal lordship of the English Crown in 1399. It never became part of the Kingdom of Great Britain or its successor the United Kingdom, retaining its status as an internally self-governing Crown dependency. http://iominternationalchess.com/ For a small country, sport in the Isle of Man plays an important part in making the island known to the wider world.

Yanofsky, Daniel Abraham (”Abe”) (26.03.1925 - 05.03.2000)
Yanofsky, Daniel Abraham (”Abe”) (26.03.1925 - 05.03.2000) First Canadian Grandmaster ever. Born in 1925 in Brody, then Poland, he arrived the same year in Canada, as an eight months young baby. A child prodigy. Brilliant technical play, especially in the endgame. Prominent Winnipeg lawyer and city councillor, Winnipeg, Manitoba, and Mayor of West Kildonan, Manitoba. Awarded the IM title in 1950 (the inaugural year), the GM title in 1964 and the International Arbiter title in 1977. The first chess player in the British Commonwealth to be awarded the Grandmaster title (Apart from German-born chess player Jacques Mieses who moved to England in the 1930s to escape Nazi persecution as a Jew. Mieses became a British citizen late in life, then received the title when FIDE first awarded the grandmaster title in 1950, Mieses was one of the 27 original recipients, and the oldest of them) Yanofsky was British Champion in 1953 and Canadian Champion on eight occasions: 1941 in 1943, 1945, 1947, 1953, 1959, 1963, 1965; his eight titles is a Canadian record (tied in closed tournaments with Maurice Fox). “Little Abie” or “Abe”, as the local newspapers called him soon, was a Child Prodigy. At age of 12, Yanofsky won the championship of Manitoba. He repeated every year through 1942, when nobody else even bothered to show up. Thereafter, Yanofsky was banned from further participation in the Manitoba provincial championship to encourage others to play in it :) At 14, was picked to play at board 2 for the Canadian Team in the Olympiad in Buenos Aires 1939. -

All rights reserved ISBN 978-5-9500433-0-7 Foreword to the English edition by Alexei Shirov, publisher of the Russian original Carpe diem Valentin...Valentin Fedorovich...when we started translating your work into English you were still alive. I thought you would see it come out but...we are all mortals...and now I can only express my belated gratitude for sharing your memories with us. I first met Valentin Kirillov shortly after I began playing chess. His job was titled “state coach”, making him responsible for selecting players for the Latvian national teams, and he was acutely aware of all chess activities in the country. He quickly noticed me, partly because he knew my father from junior competitions. In January 1984, at the tender age of eleven years old, I joined Alexander Shabalov and Vidvuds Ozolins in the Soviet Under 18 Championship held in distant Kirovabad (now Ganja) in Azerbaijan. Kirillov was the head of the Latvian delegation, and I had no personal coach at the time. My openings were awful, my opponents were much older and far more experienced, and so no wonder I started out with 0.5 out of 5.
