												  Combinatorics on the ChessboardCombinatorics 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.

												  FIDE Laws of ChessFIDE Laws of Chess FIDE Laws of Chess cover over-the-board play. The Laws of Chess have two parts: 1. Basic Rules of Play and 2. Competition Rules. The English text is the authentic version of the Laws of Chess (which was adopted at the 84th FIDE Congress at Tallinn (Estonia) coming into force on 1 July 2014. In these Laws the words ‘he’, ‘him’, and ‘his’ shall be considered to include ‘she’ and ‘her’. PREFACE The Laws of Chess cannot cover all possible situations that may arise during a game, nor can they regulate all administrative questions. Where cases are not precisely regulated by an Article of the Laws, it should be possible to reach a correct decision by studying analogous situations which are discussed in the Laws. The Laws assume that arbiters have the necessary competence, sound judgement and absolute objectivity. Too detailed a rule might deprive the arbiter of his freedom of judgement and thus prevent him from finding a solution to a problem dictated by fairness, logic and special factors. FIDE appeals to all chess players and federations to accept this view. A necessary condition for a game to be rated by FIDE is that it shall be played according to the FIDE Laws of Chess. It is recommended that competitive games not rated by FIDE be played according to the FIDE Laws of Chess. Member federations may ask FIDE to give a ruling on matters relating to the Laws of Chess. BASIC RULES OF PLAY Article 1: The nature and objectives of the game of chess 1.1 The game of chess is played between two opponents who move their pieces on a square board called a ‘chessboard’.

												  PGN/AN Verification for Legal Chess GameplayPGN/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.

												  Rules of Chess960Rules of Chess960 A little known and long-discarded offshoot of Classical Chess is the realm of so-called "Randomized Chess" in its various forms. Chess960 stands for Bobby Fischer's new and improved version of "Randomized Chess". Chess960 uses algebraic notation exclusively At the start of every game of a Chess960 game, both players Pawns are set up exactly as they are at the start of every game of Classical Chess. In Chess960, just before the start of every game, both players pieces on their respective back rows receive an identical random shuffle using the Chess960 Computerized Shuffler, which is programmed to set up the pieces in any combination, with the provisos that one Rook has to be to the left and one Rook has to be to the right of the King, and one Bishop has to be on a light- colored square and one Bishop has to be on a dark-colored square. White and Black have identical positions. From behind their respective Pawns the opponents pieces are facing each other directly, symmetrically. Thus for example, if the shuffler places White's back row pieces in the following position: Ra1, Bb1, Kc1, Nd1, Be1, Nf1, Rg1, Qh1, it will place Black's back row Pieces in the following position, Ra8, Bb8, Kc8, Nd8, Be8, Nf8, Rg8, Qh8, etc. (See diagram) In Chess960 there are 960 possible starting positions, the Classical Chess starting position and 959 other starting positions. Of necessity, In Chess960 the castling rule is somewhat modified and broadened to allow for the possibility of each player castling either on or into his or her left side or on or into his or her right side of the board from all of these 960 starting positions.
