Tablebases

t. In 1977, Thompson showed up at the World Computer Chess Championship th a new creation, a database that played the king and queen versus king and rook endgame perfectly. (KQKR is the abbreviation.) It wasn'1 an engine; there was no thinking required. Thompson had generated a database that essentially solved chess backwards, what we call retrograde analysis. It started from checkmate and worked its way back until it contained every single possible position with that material balance. Then i...

 How Computational Review of Chess Games Revealed Narrativ...

Paradoxically, when other top players wrote about games in magazines and newspaper columns they often made more mistakes in their commentary than the players had made at the board. Even when the players themselves published analyses of their own games they were often less accurate than when they were playing the game. Strong moves were called errors, weak moves were praised. It was not only a few cases of journalists who were lousy players failing to comprehend the genius of the champions, or...

 Processing Power to Chess Rating Ratio

50 here is what the Deep Thought team wrote about the relationship between search depth and chess strength in a 1989 article: The ascent of the brute-force chess machines back in the late 1970s made one thing crystal clear: there is a strong causal relationship between the search speed of a chess machine and its playing strength. In fact, it appeared from machine self-test games that every time a machine searches one extra ply, its rating increases by about 200-250 rating points. Since each...

 The Chess Stress Response

Another aspect of chess as a sport is the intense psychological and physiological exertion involved in a competitive chess game, and the crisis after the game. What sports science calls the "stress response process" is at least as powerful in chess as it is in more physical sports. When I say exertion, I am not referring only to the mental gymnastics of moving the pieces in our minds, but also the huge nervous tension that fills you before and during the game, tension that rises and falls wit...

 Chess is the Drosophila of Reasoning

Much as the Drosophila melanogaster fruit fly became a model organism for geneticists, chess became a Drosophila of reasoning. In the late 19th century, Alfred Binet hoped that understanding why certain people excelled at chess would unlock secrets of human thought. Sixty years later, Alan Turing wondered if a chess-playing machine might illuminate, in the words of Norbert Wiener, “whether this sort of ability represents an essential difference between the potentialities of the machine and ...

 Defining Play and Transformative Play

Transformative play is a special case of play that occurs when the free movement of play alters the more rigid structure in which it takes shape. The play doesn't just occupy and oppose the interstices of the system, but actually transforms the space as a whole. A cyberfeminist game patch that creates transsexual versions of Lara Croft is an example of transformative play, as is the use of the Quake game engine as a movie-making tool. Although every instance of play involves free movement wi...

 Types of Information in Games

In The Interactive Book, designer and scholar Celia Pearce presents a different typology for understanding the ways games manifest information. She proposes four scenarios: · Information known to all players: In Chess, this would consist of the rules of the game, board layout, and piece movement parameters. · Information known to only one player: In Gin, this would be the cards in your hand. · Information known to the game only: In Gin, this would be unused cards in deck. In Space Invad...

 Games Exist in Symbols and Syntax

Consider the game of Chess. Typically it's played with a collection of Chess pieces on a chessboard consisting of black and white squares. We can all agree, I think, that these are indeed real-world objects. Moreover, the game involves a set of rules specifying how the pieces can move, what constitutes a legal position on the board, how one piece captures another and so forth. This is the real-world version of the game of Chess. But there is another version, one existing purely in the world o...

 The Universe as a Game Where the Rules are Hidden

‘I talked to a woman of the Kaminari once,’ he says, ‘before the Spike. Don’t give me such a look, it wasn’t like that, we were just friends. But one night on Ganymede, we got philosophical. The Universe is a game, she said. It makes us into players. We can’t see the moves that are not allowed. Like in chess. There is perfect freedom in the black and white, except that the rules make invisible walls. Two squares forward, one left. One left, whole row forward and backward, one righ...

 Understanding Physics is Like Learning Chess

The physicist is like someone who's watching people playing chess and, after watching a few games, he may have worked out what the moves in the game are. But understanding the rules is just a trivial preliminary on the long route from being a novice to being a grand master. So even if we understand all the laws of physics, then exploring their consequences in the everyday world where complex structures can exist is a far more daunting task, and that's an inexhaustible one I'm sure.
