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. -
Parallel Chess Searching and Bitboards
Parallel Chess Searching and Bitboards David Ravn Rasmussen August 2004 Abstract In order to make chess programs faster and thus stronger, the two approaches of parallelizing the search and of using clever data structures have been suc- cessful in the past. In this project it is examined how the use of a specific data structure called a bitboard affects the performance of parallel search. For this, a realistic bitboard chess program with important modern enhance- ments is implemented, and several experiments are done to evaluate the performance of the implementation. A maximum speedup of 9.2 on 22 pro- cessors is achieved in one experiment and a maximum speedup of 9.4 on 12 processors is achieved in another experiment. These results indicate that bitboards are a realistic choice of data structure in a parallel chess program, although the considerable difference in the two results suggests that more research could be done to clarify what factors affect such an implementation, and how.

1 Najdorf Sicilian will try to keep full control over the d5 Focus on the Critical d5 Squar square, and try to maintain the possibility of placing and keeping a piece One the most common openings in the on d5. Fully controlling the d5 square past 50 years is the Najdorf variation of allows white to affect both sides of the the Sicilian Defense. The Najdorf offers board. In order to assure that control, many different possibilities, starting from white wants to trade off black pieces extremely sharp, poison pawn variation that can control d5. For example, he (1. e4, c5 2. nf3 d6 3. d4 cxd4 4. Nxd4 wants to play with Bg5, in order to trade Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Qb6 8. off the Knight on f6. He also will Qd2 Qxb2! ) to extremely positional lines increase the number of his own pieces (1. e4, c5 2. nf3 d6 3. d4 cxd4 4. Nxd4 that can control d5, with maneuvers like Nf6 5. Nc3 a6 6.

Feel free to save, print, or distribute this PDF as needed. Section 1: Background Information History ● Chess is widely assumed to have originated in India around the seventh century. ● Until the mid-1400s in Europe, chess was known as shatranj, which had different rules than modern chess. ● Some well-known authors and chess players from that time period are Greco, Lucena, and Ruy Lopez. ● The Romantic Era lasted from the late 18th century until the middle of the 19th century, and was characterized by sacrifices and aggressive play. ● Chess has widely been considered a sport since the late 1800s, when the World Chess Championship was organized for the first time. Other ● Chess is considered a game of planning and strategy because it is a game with no hidden information, where you and your opponent have the same pieces, so there is no luck. ● Studying chess seriously can bring you many benefits, but simply playing it won’t make you smarter. Section 2: Rules of the Game Setting Up the Board ● There are sixty-four squares on the board, and thirty-two pieces (sixteen per player). ● Each player’s pieces are made up of eight pawns, two knights, two bishops, two rooks, a queen, and a king. ● There are two players, Black and White. White moves first. ● If you’re using a physical board, rotate the board until there is a light square on the bottom right for each player. -
