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. -

Little Chess Evaluation Compendium by Lyudmil Tsvetkov, Sofia, Bulgaria
Little Chess Evaluation Compendium By Lyudmil Tsvetkov, Sofia, Bulgaria Version from 2012, an update to an original version first released in 2010 The purpose will be to give a fairly precise evaluation for all the most important terms. Some authors might find some interesting ideas. For abbreviations, p will mean pawns, cp – centipawns, if the number is not indicated it will be centipawns, mps - millipawns; b – bishop, n – knight, k- king, q – queen and r –rook. Also b will mean black and w – white. We will assume that the bishop value is 3ps, knight value – 3ps, rook value – 4.5 ps and queen value – 9ps. In brackets I will be giving purely speculative numbers for possible Elo increase if a specific function is implemented (only for the functions that might not be generally implemented). The exposition will be split in 3 parts, reflecting that opening, middlegame and endgame are very different from one another. The essence of chess in two words Chess is a game of capturing. This is the single most important thing worth considering. But in order to be able to capture well, you should consider a variety of other specific rules. The more rules you consider, the better you will be able to capture. If you consider 10 rules, you will be able to capture. If you consider 100 rules, you will be able to capture in a sufficiently good way. If you consider 1000 rules, you will be able to capture in an excellent way. The philosophy of chess Chess is a game of correlation, and not a game of fixed values. -

The Wangling Wizards the Chess Problems of the Warton Brothers
The Wangling Wizards The chess problems of the Warton brothers Compiled by Michael McDowell ½ û White to play and mate in 3 British Chess Problem Society 2005 The Wangling Wizards Introduction Tom and Joe Warton were two of the most popular British chess problem composers of the twentieth century. They were often compared to the American "Puzzle King" Sam Loyd because they rarely composed problems illustrating formal themes, instead directing their energies towards hoodwinking the solver. Piquant keys and well-concealed manoeuvres formed the basis of a style that became known as "Wartonesque" and earned the brothers the nickname "the Wangling Wizards". Thomas Joseph Warton was born on 18 th July 1885 at South Mimms, Hertfordshire, and Joseph John Warton on 22 nd September 1900 at Notting Hill, London. Another brother, Edwin, also composed problems, and there may have been a fourth composing Warton, as a two-mover appeared in the August 1916 issue of the Chess Amateur under the name G. F. Warton. After a brief flourish Edwin abandoned composition, although as late as 1946 he published a problem in Chess . Tom and Joe began composing around 1913. After Tom’s early retirement from the Metropolitan Police Force they churned out problems by the hundred, both individually and as a duo, their total output having been estimated at over 2600 problems. Tom died on 23rd May 1955. Joe continued to compose, and in the 1960s published a number of joints with Jim Cresswell, problem editor of the Busmen's Chess Review , who shared his liking for mutates. Many pleasing works appeared in the BCR under their amusing pseudonym "Wartocress". -
Touring Problems – a Mathematical Approach
TOURING PROBLEMS – A MATHEMATICAL APPROACH VIPUL NAIK Abstract. The article surveys “touring”, a problem of “fun” math, and employs serious techniques to attack it. The text is suitable for high school students interested in Olympiad mathematics, as well as undergraduate students studying combinatorics and discrete math- ematics. It can be used to introduce the concept of a graph. A sequel to this article, on a similar analysis for “tiling” problems, shall also appear soon. 1. Prebeginnings 1.1. The knight’s tour. Chess pieces, with their variously defined moves, are a rich source of puzzles in recreational mathematics. Chess puzzles include the following types : • Nonattacking pieces puzzle : Given a piece with some moves defined, place as many copies of this piece as possible so that no two can kill each other. The proto- typical example of this is the eight queens problem – placing eight queens on the chessboard so that no two can kill each other. • Board domination puzzle : Given a piece with some moves defined, place as few copies of the piece as possible so that every square is either covered by some copy or is under direct attack by a copy of the piece. • Touring puzzle : Given a piece with some moves defined, construct a tour of the entire chessboard with that piece. The only nontrivial case of this for a standard chess piece is the knight’s tour. Each of these problems revolves around a piece, with certain moves defined for that piece. Instead of standard chess pieces, we may sometimes be interested in defining chess pieces with somewhat different moves. -

ENDING the ENERGY STALEMATE a Bipartisan Strategy to Meet America’S Energy Challenges
ENDING THE ENERGY STALEMATE A Bipartisan Strategy to Meet America’s Energy Challenges THE NATIONAL COMMISSION ON ENERGY POLICY December 2004 Cover: U.S. Government Satellite Images: Western Hemisphere at Night ENDING THE ENERGY STALEMATE A Bipartisan Strategy to Meet America’s Energy Challenges THE NATIONAL COMMISSION ON ENERGY POLICY December 2004 www.energycommission.org PREAMBLE This report is a product of a bipartisan Commission of 16 members of diverse expertise and affiliations, addressing many complex and contentious topics. It is inevitable that arriving at a consensus document in these circumstances entailed innumerable compromises. Accordingly, it should not be assumed that every member is entirely satisfied with every formulation in the report, or even that all of us would agree with any given recommendation if it were taken in isolation. Rather, we have reached consensus on the report and its recommendations as a package, which taken as a whole offers a balanced and comprehensive approach to the economic, national security, and environmental challenges that the energy issue presents to our nation. ACKNOWLEDGEMENTS The National Commission on Energy Policy was founded in 2002 by the William and Flora Hewlett Foundation and its partners: The Pew Charitable Trusts, the John D. and Catherine T. MacArthur Foundation, the David and Lucile Packard Foundation, and the Energy Foundation. The Commission would like to express its sincere appreciation for the Hewlett Foundation’s vision and the strong support of its partners. The Commission would also like to thank the following Commissioner representatives for their many contributions to the Commission’s ongoing work and to this report: Gordon Binder, Principal, Aqua International Partners; Kelly Sims Gallagher, Director, Energy Technology Innovation Project, Belfer Center for Science & International Affairs, Harvard University; Marianne S. -
