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.

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. -
Algorithmic Combinatorial Game Theory∗
Playing Games with Algorithms: Algorithmic Combinatorial Game Theory∗ Erik D. Demaine† Robert A. Hearn‡ Abstract Combinatorial games lead to several interesting, clean problems in algorithms and complexity theory, many of which remain open. The purpose of this paper is to provide an overview of the area to encourage further research. In particular, we begin with general background in Combinatorial Game Theory, which analyzes ideal play in perfect-information games, and Constraint Logic, which provides a framework for showing hardness. Then we survey results about the complexity of determining ideal play in these games, and the related problems of solving puzzles, in terms of both polynomial-time algorithms and computational intractability results. Our review of background and survey of algorithmic results are by no means complete, but should serve as a useful primer. 1 Introduction Many classic games are known to be computationally intractable (assuming P 6= NP): one-player puzzles are often NP-complete (as in Minesweeper) or PSPACE-complete (as in Rush Hour), and two-player games are often PSPACE-complete (as in Othello) or EXPTIME-complete (as in Check- ers, Chess, and Go). Surprisingly, many seemingly simple puzzles and games are also hard. Other results are positive, proving that some games can be played optimally in polynomial time. In some cases, particularly with one-player puzzles, the computationally tractable games are still interesting for humans to play. We begin by reviewing some basics of Combinatorial Game Theory in Section 2, which gives tools for designing algorithms, followed by reviewing the relatively new theory of Constraint Logic in Section 3, which gives tools for proving hardness. -
Klondike (Sam Loyd)
Back From The Klondike by Sam Loyd The original puzzle was in black and white and had 1 challange: Start from that heart in the center and go three steps in a straight line in any one of the eight directions, north, south, east or west, or northeast, northwest, southeast or southwest. When you have gone three steps in a straight line, you will reach a square with a number on it, which indicates the second day's journey, as many steps as it tells, in a straight line in any of the eight directions. From this new point when reached, march on again according to the number indicated, and continue on, following the requirements of the numbers reached, until you come upon a square with a number which will carry you just one step beyond the border, when you are supposed to be out of the woods and can holler all you want, as you will have solved the puzzle. Joseph Eitel!Page 1 of 6!amagicclassroom.com Back From the Klondike Version 2 This maze was among the many puzzles Loyd created for newspapers beginning in 1890. In this version some squares are yellow or green. This allowed better explanations how the puzzle worked. The numbers in each square in the grid indicate how many squares you can travel in a straight line horizontally, vertically, or diagonally from that square. For example, if you start in the red square in the center, your first move can take you to any one of the three yellow squares. The green squares are some of the possible squares you could land on for the second move. -

At the age of three, his family moved in 1841 (O to New York where he attended public school (Carter). Sam Loyd got his start in the puzzle business with chess. At 14 years of age, Loyd started attending chess club with two of his older “New brothers. On April 14th, that same year, Loyd had his first chess problem published in the ” In 1856, the “New York Clipper” published another of his chess York Saturday Courier. ’Conner). At first, all of Loyd’s puzzles were hobbies. problems for which he won a prize (O After school he studied engineering and earned a license in steam and mechanical engineering (Loyd). For a time, Loyd supported himself as a plumbing contractor and the owner of a chain of ’Conner). Plus, music stores. He was also a skilled cartoonist and a self taught wood engraver (O he was skilled in conjuring, mimicry, ventriloquism and silhouette cutting (Gardner). Eventually, Loyd left plumbing behind and focused on mathematical puzzles. He attended chess tournaments, wrote and edited mechanical journals along with his magazine “Sam Loyd’s Puzzle Magazine” (O’Conner). For a while, he also edited the magazine entitled “Chess Monthly” and the chess page of “Scientific American” (Gardner). P. T. Barnum’s Trick ’Conner).

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.

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.
