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. -

Chess Rules Ages 10 & up • for 2 Players
Front (Head to Head) Prints Pantone 541 Blue Chess Rules Ages 10 & Up • For 2 Players Contents: Game Board, 16 ivory and 16 black Play Pieces Object: To threaten your opponent’s King so it cannot escape. Play Pieces: Set Up: Ivory Play Pieces: Black Play Pieces: Pawn Knight Bishop Rook Queen King Terms: Ranks are the rows of squares that run horizontally on the Game Board and Files are the columns that run vertically. Diagonals run diagonally. Position the Game Board so that the red square is at the bottom right corner for each player. Place the Ivory Play Pieces on the first rank from left to right in order: Rook, Knight, Bishop, Queen, King, Bishop, Knight and Rook. Place all of the Pawns on the second rank. Then place the Black Play Pieces on the board as shown in the diagram. Note: the Ivory Queen will be on a red square and the black Queen will be on a black space. Play: Ivory always plays first. Players alternate turns. Only one Play Piece may be moved on a turn, except when castling (see description on back). All Play Pieces must move in a straight path, except for the Knight. Also, the Knight is the only Play Piece that is allowed to jump over another Play Piece. Play Piece Moves: A Pawn moves forward one square at a time. There are two exceptions to this rule: 1. On a Pawn’s first move, it can move forward one or two squares. 2. When capturing a piece (see description on back), a Pawn moves one square diagonally ahead. -
Extended Null-Move Reductions
Extended Null-Move Reductions Omid David-Tabibi1 and Nathan S. Netanyahu1,2 1 Department of Computer Science, Bar-Ilan University, Ramat-Gan 52900, Israel [email protected], [email protected] 2 Center for Automation Research, University of Maryland, College Park, MD 20742, USA [email protected] Abstract. In this paper we review the conventional versions of null- move pruning, and present our enhancements which allow for a deeper search with greater accuracy. While the conventional versions of null- move pruning use reduction values of R ≤ 3, we use an aggressive re- duction value of R = 4 within a verified adaptive configuration which maximizes the benefit from the more aggressive pruning, while limiting its tactical liabilities. Our experimental results using our grandmaster- level chess program, Falcon, show that our null-move reductions (NMR) outperform the conventional methods, with the tactical benefits of the deeper search dominating the deficiencies. Moreover, unlike standard null-move pruning, which fails badly in zugzwang positions, NMR is impervious to zugzwangs. Finally, the implementation of NMR in any program already using null-move pruning requires a modification of only a few lines of code. 1 Introduction Chess programs trying to search the same way humans think by generating “plausible” moves dominated until the mid-1970s. By using extensive chess knowledge at each node, these programs selected a few moves which they consid- ered plausible, and thus pruned large parts of the search tree. However, plausible- move generating programs had serious tactical shortcomings, and as soon as brute-force search programs such as Tech [17] and Chess 4.x [29] managed to reach depths of 5 plies and more, plausible-move generating programs fre- quently lost to brute-force searchers due to their tactical weaknesses. -

KASPAROV VERSUS DEEP BLUE : COMPUTER CHESS COMES OF AGE PDF, EPUB, EBOOK Monty Newborn | 322 pages | 31 Jul 2012 | Springer-Verlag New York Inc. | 9781461274773 | English | New York, NY, United States Kasparov versus Deep Blue : Computer Chess Comes of Age PDF Book In terms of human comparison, the already existing hierarchy of rated chess players throughout the world gave engineers a scale with which to easily and accurately measure the success of their machine. This was the position on the board after 35 moves. Nxh5 Nd2 Kg4 Bc7 Famously, the mechanical Turk developed in thrilled and confounded luminaries as notable as Napoleon Bonaparte and Benjamin Franklin. Kf1 Bc3 Deep Blue. The only reason Deep Blue played in that way, as was later revealed, was because that very same day of the game the creators of Deep Blue had inputted the variation into the opening database. KevinC The allegation was that a grandmaster, presumably a top rival, had been behind the move. When it's in the open, anyone could respond to them, including people who do understand them. Qe2 Qd8 Bf3 Nd3 IBM Research. Nearly two decades later, the match still fascinates This week Time Magazine ran a story on the famous series of matches between IBM's supercomputer and Garry Kasparov. Because once you have an agenda, where does indifference fit into the picture? Raa6 Ba7 Black would have acquired strong counterplay. In fact, the first move I looked at was the immediate 36 Be4, but in a game, for the same safety-first reasons the black counterplay with a5 I might well have opted for 36 axb5.
