Chessmaster - Chess Engine

Chess Engine

The Chessmaster chess engine is called The King, written by Johan de Koning of the Netherlands. It was introduced in Chessmaster 4000; earlier releases featured a chess engine written by David Kittinger.

According to the September 2009 Swedish Chess Computer Association (SSDF) rating list, Chessmaster 9000 has an estimated Elo rating of 2718 on an Athlon-1200 PC. If multiple versions of other engines are stripped out of their list, Chessmaster 9000 ranks 14th among all engines tested. As of May 2008, Chessmaster 9000 remains the most recent version rated by the SSDF. Another rating list, CCRL, places Chessmaster 11th Edition in 24th place on its December 2009 list.

The King engine allows users to create new playing styles, also called "personalities", by manipulating several dozen different settings, such as King Safety, Pawn Weakness, Randomness, Mobility and others. Individual piece values can also be adjusted. Chessmaster 9000, for example, features over 150 different personalities ranging from International Grandmaster strength down to Stanley, who is described as a monkey and plays what are essentially random moves.

The personality feature has inspired many amateur computer chess enthusiasts to attempt to find more optimum personalities. In Chessmaster 10th Edition, the creation of new personalities has been made easier than before.

Famous quotes containing the words chess and/or engine:

    Work, as we usually think of it, is energy expended for a further end in view; play is energy expended for its own sake, as with children’s play, or as manifestation of the end or goal of work, as in “playing” chess or the piano. Play in this sense, then, is the fulfillment of work, the exhibition of what the work has been done for.
    Northrop Frye (1912–1991)

    There is a small steam engine in his brain which not only sets the cerebral mass in motion, but keeps the owner in hot water.
    —Unknown. New York Weekly Mirror (July 5, 1845)
