11 Triple Loyd
TTHHEE PPUUZZZZLLIINNGG SSIIDDEE OOFF CCHHEESSSS Jeff Coakley TRIPLE LOYDS: BLACK PIECES number 11 September 22, 2012 The “triple loyd” is a puzzle that appears every few weeks on The Puzzling Side of Chess. It is named after Sam Loyd, the American chess composer who published the prototype in 1866. In this column, we feature positions that include black pieces. A triple loyd is three puzzles in one. In each part, your task is to place the black king on the board.to achieve a certain goal. Triple Loyd 07 w________w áKdwdwdwd] àdwdwdwdw] ßwdwdw$wd] ÞdwdRdwdw] Ýwdwdwdwd] Üdwdwdwdw] Ûwdwdpdwd] Údwdwdwdw] wÁÂÃÄÅÆÇÈw Place the black king on the board so that: A. Black is in checkmate. B. Black is in stalemate. C. White has a mate in 1. For triple loyds 1-6 and additional information on Sam Loyd, see columns 1 and 5 in the archives. As you probably noticed from the first puzzle, finding the stalemate (part B) can be easy if Black has any mobile pieces. The black king must be placed to take away their moves.

Proposal to Encode Heterodox Chess Symbols in the UCS Source: Garth Wallace Status: Individual Contribution Date: 2016-10-25
Title: Proposal to Encode Heterodox Chess Symbols in the UCS Source: Garth Wallace Status: Individual Contribution Date: 2016-10-25 Introduction The UCS contains symbols for the game of chess in the Miscellaneous Symbols block. These are used in figurine notation, a common variation on algebraic notation in which pieces are represented in running text using the same symbols as are found in diagrams. While the symbols already encoded in Unicode are sufficient for use in the orthodox game, they are insufficient for many chess problems and variant games, which make use of extended sets. 1. Fairy chess problems The presentation of chess positions as puzzles to be solved predates the existence of the modern game, dating back to the mansūbāt composed for shatranj, the Muslim predecessor of chess. In modern chess problems, a position is provided along with a stipulation such as “white to move and mate in two”, and the solver is tasked with finding a move (called a “key”) that satisfies the stipulation regardless of a hypothetical opposing player’s moves in response. These solutions are given in the same notation as lines of play in over-the-board games: typically algebraic notation, using abbreviations for the names of pieces, or figurine algebraic notation. Problem composers have not limited themselves to the materials of the conventional game, but have experimented with different board sizes and geometries, altered rules, goals other than checkmate, and different pieces. Problems that diverge from the standard game comprise a genre called “fairy chess”. Thomas Rayner Dawson, known as the “father of fairy chess”, pop- ularized the genre in the early 20th century. -
A GUIDE to SCHOLASTIC CHESS (11Th Edition Revised June 26, 2021)
A GUIDE TO SCHOLASTIC CHESS (11th Edition Revised June 26, 2021) PREFACE Dear Administrator, Teacher, or Coach This guide was created to help teachers and scholastic chess organizers who wish to begin, improve, or strengthen their school chess program. It covers how to organize a school chess club, run tournaments, keep interest high, and generate administrative, school district, parental and public support. I would like to thank the United States Chess Federation Club Development Committee, especially former Chairman Randy Siebert, for allowing us to use the framework of The Guide to a Successful Chess Club (1985) as a basis for this book. In addition, I want to thank FIDE Master Tom Brownscombe (NV), National Tournament Director, and the United States Chess Federation (US Chess) for their continuing help in the preparation of this publication. Scholastic chess, under the guidance of US Chess, has greatly expanded and made it possible for the wide distribution of this Guide. I look forward to working with them on many projects in the future. The following scholastic organizers reviewed various editions of this work and made many suggestions, which have been included. Thanks go to Jay Blem (CA), Leo Cotter (CA), Stephan Dann (MA), Bob Fischer (IN), Doug Meux (NM), Andy Nowak (NM), Andrew Smith (CA), Brian Bugbee (NY), WIM Beatriz Marinello (NY), WIM Alexey Root (TX), Ernest Schlich (VA), Tim Just (IL), Karis Bellisario and many others too numerous to mention. Finally, a special thanks to my wife, Susan, who has been patient and understanding. Dewain R. Barber Technical Editor: Tim Just (Author of My Opponent is Eating a Doughnut and Just Law; Editor 5th, 6th and 7th editions of the Official Rules of Chess). -

The process of composing a chess endgame study using computer analysis tools, including endgame tablebases, is cited as an example of the partnership between an AI device and a human creator. I conclude with a suggestion to distinguish creative value from financial profit in evaluating IP issues in AI inventions, based on the fact that most chess puzzle composers follow IP conventions despite lacking any expectation of financial profit.

New Directions in Enumerative Chess Problems to Richard Stanley on the Occasion of His 60Th Birthday
New directions in enumerative chess problems to Richard Stanley on the occasion of his 60th birthday Noam D. Elkies Department of Mathematics Harvard University Cambridge, MA 02138 [email protected] Submitted: Jun 30, 2005; Accepted: Aug 1, 2005; Published: Aug 24, 2005 Mathematics Subject Classifications: 05A10, 05A15, 05E10, 97A20 Abstract Normally a chess problem must have a unique solution, and is deemed unsound even if there are alternatives that differ only in the order in which the same moves are played. In an enumerative chess problem, the set of moves in the solution is (usually) unique but the order is not, and the task is to count the feasible permutations via an isomorphic problem in enumerative combinatorics. Almost all enumerative chess problems have been \series-movers", in which one side plays an uninterrupted series of moves, unanswered except possibly for one move by the opponent at the end. This can be convenient for setting up enumeration problems, but we show that other problem genres also lend themselves to composing enumerative problems. Some of the resulting enumerations cannot be shown (or have not yet been shown) in series-movers. This article is based on a presentation given at the banquet in honor of Richard Stanley's 60th birthday, and is dedicated to Stanley on this occasion. 1 Motivation and overview Normally a chess problem must have a unique solution, and is deemed unsound even if there are alternatives that differ only in the order in which the same moves are played. In an enumerative chess problem, the set of moves in the solution is (usually) unique but the order is not, and the task is to count the feasible permutations via an isomorphic problem in enumerative combinatorics. -

Solving a Hypothetical Chess Problem: a Comparative Analysis of Computational Methods and Human Reasoning
Revista Brasileira de Computação Aplicada, Abril, 2019 DOI: 10.5335/rbca.v11i1.9111 Vol. 11, No 1, pp. 96–103 Homepage: seer.upf.br/index.php/rbca/index ORIGINALPAPER Solving a hypothetical chess problem: a comparative analysis of computational methods and human reasoning Léo Pasqualini de Andrade1, Augusto Cláudio Santa Brígida Tirado1, Valério Brusamolin1 and Mateus das Neves Gomes1 1Instituto Federal do Paraná, campus Paranaguá *[email protected]; [email protected]; [email protected]; [email protected] Received: 2019-02-15. Revised: 2019-02-27. Accepted: 2019-03-15. Abstract Computational modeling has enabled researchers to simulate tasks which are very often impossible in practice, such as deciphering the working of the human mind, and chess is used by many cognitive scientists as an investigative tool in studies on intelligence, behavioral patterns and cognitive development and rehabilitation. Computer analysis of databases with millions of chess games allows players’ cognitive development to be predicted and their behavioral patterns to be investigated. However, computers are not yet able to solve chess problems in which human intelligence analyzes and evaluates abstractly without the need for many concrete calculations. The aim of this article is to describe and simulate a chess problem situation proposed by the British mathematician Sir Roger Penrose and thus provide an opportunity for a comparative discussion by society of human and articial intelligence. To this end, a specialist chess computer program, Fritz 12, was used to simulate possible moves for the proposed problem. The program calculated the variations and reached a dierent result from that an amateur chess player would reach after analyzing the problem for only a short time. -

48 Helpmates: Black to Play and Lose
TTHHEE PPUUZZZZLLIINNGG SSIIDDEE OOFF CCHHEESSSS Jeff Coakley HELPMATES: BLACK TO PLAY AND LOSE number 48 September 28, 2013 In the world of chess composition, only direct mates and endgame studies can rival the popularity of helpmates. There are more than 100,000 known problems. If you solve ten everyday, it will only take you thirty years to do them all! Let’s get started. In a helpmate, Black cooperates with White to checkmate the black king. In other words, Black plays the worst moves possible. White has an ally, not an opponent. Otherwise the normal rules of chess are followed. Unless stated differently, Black always moves first. The first three puzzles are helpmates in one. Find the black move that allows an immediate checkmate. Black moves, White mates. Easy! Helpmate 01 w________w áRdwdw4kd] àdQdwdwdp] ßwdpdwdpd] Þdwgw1ndN] Ýwdwdwdwd] Üdw)wdwdw] Ûw)wdw4w)] ÚdwIwdw$w] wÁÂÃÄÅÆÇÈw Helpmate in 1 Black plays first. Find the move that lets White play mate in one. A Note on Notation One unusual thing about helpmates is the notation used for solutions. The convention is to write Black’s move first, right after the move number, followed by White’s move. The opposite of standard notation. For example, in helpmate notation, 1.f5 e4 2.g5 Qh5# means that Black plays pawn to f5 and White answers with pawn to e4. Black then pushes pawn to g5 and White mates with queen to h5.

Chess Problem Composing Steps
Appendix A Chess Problem Composing Steps Chess problems for this research were composed automatically using CHESTHETICA (see Fig. A.1) following the essential steps below. It is a modi- fication of the approach used in (Iqbal 2011). The problems composed are limited to orthodox mate-in-3 problems in standard international chess. 1. Obtain the two new DSNS strings produced from the DSNS process (see Sect. 3.1). 2. Set the total number of white pieces and black pieces that can be used in the composition. There are two attribute values pertaining to these features in each DSNS string. (a) For example, if in string 1 the white piece count is 5 and in string 2 the white piece count is 10, the range possible for this computer composition is between 5 and 10. The same for the black pieces. 3. Calculate the total Shannon value of the white pieces and then the black pieces in both strings and get the average of each. Use these average values to determine the number of piece permutations (i.e. combinations of different pieces) that satisfy them. (a) For example, an average value of 10 for white could mean having a bishop, two knights and a pawn whereas an average value of 9 for black could mean having just a queen. The total number of piece permutations possible for both the white and black pieces here is totaled. (b) This total will equal the number of times the same pair of DSNS strings is used in attempting to generate a composition. So, in principle, every legal piece combination can be tested. -
