Bleicher Reading, U.K., Deventer, the Netherlands and Berlin, Germany ABSTRACT Van der Heijden’s ENDGAME STUDY DATABASE IV, HHDBIV, is the definitive collection of 76,132 chess studies. The zugzwang position or zug, one in which the side to move would prefer not to, is a frequent theme in the literature of chess studies. In this third data-mining of HHDBIV, we report on the occurrence of sub-7-man zugs there as discovered by the use of CQL and Nalimov endgame tables (EGTs). We also mine those Zugzwang Studies in which a zug more significantly appears in both its White-to-move (wtm) and Black-to-move (btm) forms. We provide some illustrative and extreme examples of zugzwangs in studies. -
Combinatorics on the Chessboard
Combinatorics on the Chessboard Interactive game: 1. On regular chessboard a rook is placed on a1 (bottom-left corner). Players A and B take alternating turns by moving the rook upwards or to the right by any distance (no left or down movements allowed). Player A makes the rst move, and the winner is whoever rst reaches h8 (top-right corner). Is there a winning strategy for any of the players? Solution: Player B has a winning strategy by keeping the rook on the diagonal. Knight problems based on invariance principle: A knight on a chessboard has a property that it moves by alternating through black and white squares: if it is on a white square, then after 1 move it will land on a black square, and vice versa. Sometimes this is called the chameleon property of the knight. This is related to invariance principle, and can be used in problems, such as: 2. A knight starts randomly moving from a1, and after n moves returns to a1. Prove that n is even. Solution: Note that a1 is a black square. Based on the chameleon property the knight will be on a white square after odd number of moves, and on a black square after even number of moves. Therefore, it can return to a1 only after even number of moves. 3. Is it possible to move a knight from a1 to h8 by visiting each square on the chessboard exactly once? Solution: Since there are 64 squares on the board, a knight would need 63 moves to get from a1 to h8 by visiting each square exactly once. -

PGN/AN Verification for Legal Chess Gameplay
PGN/AN Verification for Legal Chess Gameplay Neil Shah Guru Prashanth [email protected] [email protected] May 10, 2015 Abstract Chess has been widely regarded as one of the world's most popular games through the past several centuries. One of the modern ways in which chess games are recorded for analysis is through the PGN/AN (Portable Game Notation/Algebraic Notation) standard, which enforces a strict set of rules for denoting moves made by each player. In this work, we examine the use of PGN/AN to record and describe moves with the intent of building a system to verify PGN/AN in order to check for validity and legality of chess games. To do so, we formally outline the abstract syntax of PGN/AN movetext and subsequently define denotational state-transition and associated termination semantics of this notation. 1 Introduction Chess is a two-player strategy board game which is played on an eight-by-eight checkered board with 64 squares. There are two players (playing with white and black pieces, respectively), which move in alternating fashion. Each player starts the game with a total of 16 pieces: one king, one queen, two rooks, two knights, two bishops and eight pawns. Each of the pieces moves in a different fashion. The game ends when one player checkmates the opponents' king by placing it under threat of capture, with no defensive moves left playable by the losing player. Games can also end with a player's resignation or mutual stalemate/draw. We examine the particulars of piece movements later in this paper. -

ANALYSIS AND IMPLEMENTATION OF THE GAME ARIMAA Christ-Jan Cox Master Thesis MICC-IKAT 06-05 THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE OF KNOWLEDGE ENGINEERING IN THE FACULTY OF GENERAL SCIENCES OF THE UNIVERSITEIT MAASTRICHT Thesis committee: prof. dr. H.J. van den Herik dr. ir. J.W.H.M. Uiterwijk dr. ir. P.H.M. Spronck dr. ir. H.H.L.M. Donkers Universiteit Maastricht Maastricht ICT Competence Centre Institute for Knowledge and Agent Technology Maastricht, The Netherlands March 2006 II Preface The title of my M.Sc. thesis is Analysis and Implementation of the Game Arimaa. The research was performed at the research institute IKAT (Institute for Knowledge and Agent Technology). The subject of research is the implementation of AI techniques for the rising game Arimaa, a two-player zero-sum board game with perfect information. Arimaa is a challenging game, too complex to be solved with present means. It was developed with the aim of creating a game in which humans can excel, but which is too difficult for computers. I wish to thank various people for helping me to bring this thesis to a good end and to support me during the actual research. First of all, I want to thank my supervisors, Prof. dr. H.J. van den Herik for reading my thesis and commenting on its readability, and my daily advisor dr. ir. J.W.H.M. Uiterwijk, without whom this thesis would not have been reached the current level and the “accompanying” depth. The other committee members are also recognised for their time and effort in reading this thesis. -
