Abstract: This article suggests a new approach to computer chess. A graph-theoretic representation of chess knowledge, uniformly based on a single mathematical abstraction, DISTANCE, is described. Most of the traditional forms of chess knowledge, it is shown, can be formalized in this new representation. In addition to comparing this approach to others, the article gives some experimental results and suggests how the new representation may be unified with existing approaches.

Abstract: This article describes in detail a selective-search heuristic which uses a null-move approach recursively. A variety of empirical data, ranging from tournament results against strong human players to special test positions, are presented. These results do not falsify the hypothesis that the heuristic should be considered as a serious candidate for controlling the search process in a chess program. Most modern microcomputer chess programs use a mixed search strategy, consisting of a brute-force part to avoid shallow tactical blunders and a selective part designed to increase the efficiency of the search at greater search depths. The second part of …our heuristic amounts to extending the search in forced positions, especially near the horizon. Show more

Abstract: We describe a suite of about 5500 test positions for testing chess-playing programs. The positions are mostly unoriginal and were optically scanned from chess books. The suite is in a number of files, each file being thematic by difficulty, tactical or positional content and others. A procedure for employing the tests is suggested and the authors describe how feedback by testees will allow them to expel the remaining errors. The suite aims at being diverse and of such difficulty that no player, human or machine, will score as much as 80%.
