Fide Online Chess Regulations
Annex 6.4 FIDE ONLINE CHESS REGULATIONS Introduction The FIDE Online Chess Regulations are intended to cover all competitions where players play on the virtual chessboard and transmit moves via the internet. Wherever possible, these Regulations are intended to be identical to the FIDE Laws of Chess and related FIDE competition regulations. They are intended for use by players and arbiters in official FIDE online competitions, and as a technical specification for online chess platforms hosting these competitions. These Regulations cannot cover all possible situations that may arise during a competition, but it should be possible for an arbiter with the necessary competence, sound judgment, and objectivity, to arrive at the correct decision based on his/her understanding of these Regulations. Annex 6.4 Contents Introduction ..................................................................................................................................... 1 Part I: Basic Rules of Play ................................................................................................................. 3 Article 1: Application of the FIDE Laws of Chess .............................................................................. 3 Part II: Online Chess Rules ............................................................................................................... 3 Article 2: Playing Zone ................................................................................................................... 3 Article 3: Moving the Pieces on -
A Combinatorial Game Theoretic Analysis of Chess Endgames
A COMBINATORIAL GAME THEORETIC ANALYSIS OF CHESS ENDGAMES QINGYUN WU, FRANK YU,¨ MICHAEL LANDRY 1. Abstract In this paper, we attempt to analyze Chess endgames using combinatorial game theory. This is a challenge, because much of combinatorial game theory applies only to games under normal play, in which players move according to a set of rules that define the game, and the last player to move wins. A game of Chess ends either in a draw (as in the game above) or when one of the players achieves checkmate. As such, the game of chess does not immediately lend itself to this type of analysis. However, we found that when we redefined certain aspects of chess, there were useful applications of the theory. (Note: We assume the reader has a knowledge of the rules of Chess prior to reading. Also, we will associate Left with white and Right with black). We first look at positions of chess involving only pawns and no kings. We treat these as combinatorial games under normal play, but with the modification that creating a passed pawn is also a win; the assumption is that promoting a pawn will ultimately lead to checkmate. Just using pawns, we have found chess positions that are equal to the games 0, 1, 2, ?, ", #, and Tiny 1. Next, we bring kings onto the chessboard and construct positions that act as game sums of the numbers and infinitesimals we found. The point is that these carefully constructed positions are games of chess played according to the rules of chess that act like sums of combinatorial games under normal play. -
Bishop and Knight Save the Day: a World Champion's Favorite Studies
Bishop and Knight Save the Day: A World Champion’s Favorite Studies Sergei Tkachenko Bishop and Knight Save the Day: A World Champion’s Favorite Studies Author: Sergei Tkachenko Translated from the Russian by Ilan Rubin Chess editor: Anastasia Travkina Typesetting by Andrei Elkov (www.elkov.ru) © LLC Elk and Ruby Publishing House, 2019. All rights reserved Cover page drawing by Anna Fokina Illustration Studio (www.fox-artwork.com) Follow us on Twitter: @ilan_ruby www.elkandruby.com ISBN 978-5-6040710-9-0 2 THE BISHOP AND THE KNIGHT HAND IN HAND… The bishop and knight pair often make chess players shudder. Why? Because of the tricky checkmate! Mating with a bishop and knight is far from simple. Indeed, there have been cases when famous players were unable to mate their opponent in the allocated 50 moves. One example involved the Kievan master Evsey Poliak. The game ended in a draw after he failed to mate his opponent with bishop, knight and king versus a lone king. After the game, somebody asked him why he didn’t chase the enemy king into a corner that was the same color as his bishop. The disappointed Poliak replied: “I kept trying to chase him but for some reason the king refused to move there!” There was even an old painting that captured this balance of forces! Back in 1793, French artist Remi-Fursy Descarsin painted a doctor playing chess against… the Grim Reaper, no less. And the doctor looks dead pleased, because he’s just mated Death himself with a bishop and knight! 3 Here’s that position from Descarsin’s painting (No. -
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. -

FIDE Laws of Chess
FIDE 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’. -
Top 10 Checkmate Pa Erns
GM Miguel Illescas and the Internet Chess Club present: Top 10 Checkmate Pa=erns GM Miguel Illescas doesn't need a presentation, but we're talking about one of the most influential chess players in the last decades, especially in Spain, just to put things in the right perspective. Miguel, so far, has won the Spanish national championship of 1995, 1998, 1999, 2001, 2004, 2005, 2007, and 2010. In team competitions, he has represented his country at many Olympiads, from 1986 onwards, and won an individual bronze medal at Turin in 2006. Miguel won international tournaments too, such as Las Palmas 1987 and 1988, Oviedo 1991, Pamplona 1991/92, 2nd at Leon 1992 (after Boris Gulko), 3rd at Chalkidiki 1992 (after Vladimir Kramnik and Joel Lautier), Lisbon Zonal 1993, and 2nd at Wijk aan Zee 1993 (after Anatoly Karpov). He kept winning during the latter part of the nineties, including Linares (MEX) 1994, Linares (ESP) Zonal 1995, Madrid 1996, and Pamplona 1997/98. Some Palmares! The ultimate goal of a chess player is to checkmate the opponent. We know that – especially at the higher level – it's rare to see someone get checkmated over the board, but when it happens, there is a sense of fulfillment that only a checkmate can give. To learn how to checkmate an opponent is not an easy task, though. Checkmating is probably the only phase of the game that can be associated with mathematics. Maths and checkmating have one crucial thing in common: patterns! GM Miguel is not going to show us a long list of checkmate examples: the series intends to teach patterns. -

More About Checkmate
MORE ABOUT CHECKMATE The Queen is the best piece of all for getting checkmate because it is so powerful and controls so many squares on the board. There are very many ways of getting CHECKMATE with a Queen. Let's have a look at some of them, and also some STALEMATE positions you must learn to avoid. You've already seen how a Rook can get CHECKMATE XABCDEFGHY with the help of a King. Put the Black King on the side of the 8-+k+-wQ-+( 7+-+-+-+-' board, the White King two squares away towards the 6-+K+-+-+& middle, and a Rook or a Queen on any safe square on the 5+-+-+-+-% same side of the board as the King will give CHECKMATE. 4-+-+-+-+$ In the first diagram the White Queen checks the Black King 3+-+-+-+-# while the White King, two squares away, stops the Black 2-+-+-+-+" King from escaping to b7, c7 or d7. If you move the Black 1+-+-+-+-! King to d8 it's still CHECKMATE: the Queen stops the Black xabcdefghy King moving to e7. But if you move the Black King to b8 is CHECKMATE! that CHECKMATE? No: the King can escape to a7. We call this sort of CHECKMATE the GUILLOTINE. The Queen comes down like a knife to chop off the Black King's head. But there's another sort of CHECKMATE that you can ABCDEFGH do with a King and Queen. We call this one the KISS OF 8-+k+-+-+( DEATH. Put the Black King on the side of the board, 7+-wQ-+-+-' the White Queen on the next square towards the middle 6-+K+-+-+& and the White King where it defends the Queen and you 5+-+-+-+-% 4-+-+-+-+$ get something like our next diagram. -

Most chess student, who are deficient in their knowledge on this topic, would find this book's study to be of benefit.
