 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...

 Asymmetrical Psychology: Computers Use Knights Better Tha...

e. Chess players have the most trouble visualizing the moves of knights because their move is unlike anything else in the game, an L-shaped hop instead of a predictable straight line like the other pieces. Computers, of course, don't visualize anything at all, and so manage every piece with equal skill. I believe it was Bent Larsen, the first GM victim of a computer in tournament play, who stated that computers dropped a few hundred rating points if you eliminated their knights. This is an ex...

 Null Move

Called the "null move" technique, it tells the engine to "pass" for one side. That is, to evaluate a position as if one player could make two moves in a row. If the position has not improved even after moving twice, then it can be assumed that the first move is a dud and can be quickly discarded from the search tree, reducing its size and making the search more efficient. Null moves were used in some of the earliest chess programs, including the Soviet Kaissa. It's elegant and a little ironic...

 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...

 Kasparov was the John Henry of Chess

HE NINETEENTH-CENTURY African American folk legend of John Henry I pits the "steel-driving man" in a race against a new invention, a steam-powered hammer, bashing a tunnel through a mountain of rock. It was my blessing and my curse to be the John Henry of chess and artificial intelligence, as chess computers went from laughably weak to nearly unbeatable during my twenty years as the world's top chess player. As we will see, this is a pattern that has repeated over and over for centuries. Pe...

 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...

 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...

 Gamification Pickup and Deliver Mechanic

Dr. Boxer decides to create a game board that depicts a cell and pieces for 12 different materials that might be transported into or out of the cell. Students are assigned to teams and given the opportunity to place certain materials either in the cell or in the bloodstream (which surrounds the cell and through which these materials move around the board). He then adds a small role-playing element to the game by giving each team an identity (such as a moving company) and an objective separate...
