MARK RUBERY CHESS

A draw in chess is a result, which may come about by:

An agreement between the players; by stalemate (a position in which a player whose turn it is to move is neither in check nor able to make a move). By repetition of position (when a position has occurred for the third time with the same player on the move)

Under the 50 move rule (If both players have made 50 moves without capturing a man or moving a pawn then a draw may be claimedat one stage FIDE made a special provision for certain endings and extended the rule to 75 moves, eg. K + 2N v K + P). The fact that a game is drawn does not necessarily indicate that the result was reached peacefully.

In the following game White gives up a rook, four pawns, a queen and then promotes his pawn to achieve a thrilling draw.

‘Under the delusion that skill at chess is evidence of high intelligence; the public has long been fascinated by the idea of chess playing machines. In 1864 Charles Babbage considered the use of a computer for this purpose, but suitable equipment was not available before the electronic age. Konrad Zuse developed the first computer aimed at playing chess in 1944 in Germany, but it was theoretical rather than practical. Zuse’s purpose being to create a symbolic language suitable for logical rather than mathematic tasks. Around 1947 the English mathematician Alan Turing specified a chess program but was unable to use a computer to run it, and instead simulated the operation by hand. In 1949 Claude Shannon of the USA presented a paper which became the basis for most subsequent research on the subject.’ (Oxford Companion to Chess)
