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. -
Social Conflict and Sacrificial Rhetoric
CHRISTOPHER ROBERTS Social Conflict and Sacrificial Rhetoric Luther’s Discursive Intervention and the Religious Division of Labor Introduction ‘Sacrifice’ is a religious term whose use extends far beyond the church door. People from all walks of life speak of ‘sacrifice’ when they want to evoke an irreducible conflict in the relations between self, family, and soci- ety. In America, hardly a speech goes by without political leaders insisting upon the necessity and virtue of sacrifice, but rarely will they clarify who is sacrificing what, and to whom. Indeed, this is not only an American phenomenon, as a number of recent texts examining ‘sacrifice’ as a term in various national discourses have shown.1 Such a political and economic deployment of a religious figure demands interpretation, for not only does the rhetoric of sacrifice span the globe,2 it constitutes a problem with a long genealogy. As a key moment in the Western segment of this genealogy, this article will examine the way that Luther’s exegetical work rhetoricalized sacrifice, and, in doing so, constructed a new discursive position, the pas- tor as anti-sophist, or parrhesiast, in the religious division of labor. The overarching question for this inquiry is how did a particular re- ligious ritual like sacrifice come to serve as such a widespread rhetorical figure? When faced with the immense historical distance between, first, the public destruction of wealth or butchering of an animal, and, last, a speech act describing non-ritual phenomena as a sacrifice, one measures the distance not only in years but also in religious and cultural transform- ation. -

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. -
A Semiotic Analysis on Signs of the English Chess Game
1 A Semiotic Analysis on Signs of the English Chess Game M. I. Andi Purnomo, Drs. Wisasongko, M.A., Hat Pujiati, S.S., M.A. English Department, Faculty of Letter, Jember University Jln. Kalimantan 37, Jember 68121 E-mail: [email protected] Abstract This thesis discusses about English Chess Game through Roland Barthes's Myth. In this thesis, I use documentary technique as method of analysis. The analysis is done by the observation of the rules, colors, and images of the English chess game. In addition, chessman and chess formation are analyzed using syntagmatic and paradigmatic relation theory to explore the correlation between symbols of the English chess game with the existence of Christian in the middle age of England. The result of this thesis shows the relation of English chess game with the history of England in the middle age where Christian ideology influences the social, military, and government political life of the English empire. Keywords: chessman, chess piece, bishops, king, knights, pawns, queen, rooks. Introduction Then, the game spread into Europe. Around 1200, the game was established in Britain and the name of “Chess” begins Game is an activity that is done by people for some (Shenk, 2006:51). It means chess spread to English during purposes. Some people use the game as a medium of the Middle Ages. The Middle Age of English begins around interaction with other people. Others use the game as the 1066 – 1485 (www.middle-ages.org.uk). At that time, the activity of spending leisure time. Others use the game as the Christian dominated the whole empire and automatically the major activity for professional. -

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. -

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.
