Evans Gambit and Giuoco Piano
Chapter Three Evans Gambit and Giuoco Piano d Introduction d Evans Gambit d Giuoco Piano Evans Gambit and Giuoco Piano Introduction These two openings arise after Black develops his bishop to the active-looking c5- square. In both cases White challenges the bishop and aims to gain time to con- struct his centre and prepare an attack. In the Evans Gambit (Games 17-19) White does this directly with 4 b4, already bar- ing his teeth and announcing to his opponent that there won’t be a comfortable ride in the opening. In the Giuoco Piano (Games 20-24) White instead plays c2-c3 and d2-d4, creating tension in the central arena before the players have had time to castle. We will examine Black’s main options in the illustrative games that follow. My impression is that if Black is serious about challenging White’s central aspirations, then he has to be willing to enter complications. The other main option, 4 d3, leading to quieter play, was dealt with separately in Chapter One. Evans Gambit 1 e4 e5 2 Nf3 Nc6 3 Bc4 Bc5 4 b4 (Diagram 1) The Evans used to be considered as a swashbuckling attempt to attack at all costs. Nowadays this view has moderated, but few would argue with the premise that it is still a risky attempt to seize the initiative. Strategy White opens lines while gaining time against the c5-bishop and, as a result, is able to create some early threats with Black’s king still in the centre. Naturally there is a price to pay for all this action: a pawn or two for a start, plus a compromised queenside, so if Black survives the early assault he may obtain the advantage. -
Combinatorics on the Chessboard
Combinatorics on the Chessboard Interactive game: 1. On regular chessboard a rook is placed on a1 (bottom-left corner). Players A and B take alternating turns by moving the rook upwards or to the right by any distance (no left or down movements allowed). Player A makes the rst move, and the winner is whoever rst reaches h8 (top-right corner). Is there a winning strategy for any of the players? Solution: Player B has a winning strategy by keeping the rook on the diagonal. Knight problems based on invariance principle: A knight on a chessboard has a property that it moves by alternating through black and white squares: if it is on a white square, then after 1 move it will land on a black square, and vice versa. Sometimes this is called the chameleon property of the knight. This is related to invariance principle, and can be used in problems, such as: 2. A knight starts randomly moving from a1, and after n moves returns to a1. Prove that n is even. Solution: Note that a1 is a black square. Based on the chameleon property the knight will be on a white square after odd number of moves, and on a black square after even number of moves. Therefore, it can return to a1 only after even number of moves. 3. Is it possible to move a knight from a1 to h8 by visiting each square on the chessboard exactly once? Solution: Since there are 64 squares on the board, a knight would need 63 moves to get from a1 to h8 by visiting each square exactly once. -

Opening Moves - Player Facts
DVD Chess Rules Chess puzzles Classic games Extras - Opening moves - Player facts General Rules The aim in the game of chess is to win by trapping your opponent's king. White always moves first and players take turns moving one game piece at a time. Movement is required every turn. Each type of piece has its own method of movement. A piece may be moved to another position or may capture an opponent's piece. This is done by landing on the appropriate square with the moving piece and removing the defending piece from play. With the exception of the knight, a piece may not move over or through any of the other pieces. When the board is set up it should be positioned so that the letters A-H face both players. When setting up, make sure that the white queen is positioned on a light square and the black queen is situated on a dark square. The two armies should be mirror images of one another. Pawn Movement Each player has eight pawns. They are the least powerful piece on the chess board, but may become equal to the most powerful. Pawns always move straight ahead unless they are capturing another piece. Generally pawns move only one square at a time. The exception is the first time a pawn is moved, it may move forward two squares as long as there are no obstructing pieces. A pawn cannot capture a piece directly in front of him but only one at a forward angle. When a pawn captures another piece the pawn takes that piece’s place on the board, and the captured piece is removed from play If a pawn gets all the way across the board to the opponent’s edge, it is promoted. -
The London System Is a Chess Opening That Usually Arises After 1.D4 and 2.Bf4, Or 2.Nf3 and 3.Bf4
ICC presents: The London System by GM Damian Lemos This is a guide that comes with the video course “The London System”. We highly recommend you first watch the video series before completing these exercises. To watch the videos, click here. The London System is a chess opening that usually arises after 1.d4 and 2.Bf4, or 2.Nf3 and 3.Bf4. It is a "system" opening that can be used against virtually any black defense and thus comprises a smaller body of opening theory than many other openings. The London is a set of solid lines where after 1.d4 White quickly develops his dark- squared bishop to f4 and normally bolsters his center with pawns on c3 and e3 rather than expanding. Although it has the potential for a quick kingside attack, the white forces are generally flexible enough to engage in a battle anywhere on the board. Historically it developed into a system mainly from three variations: 1.d4 d5 2.Nf3 Nf6 3.Bf4 1.d4 Nf6 2.Nf3 e6 3.Bf4 1.d4 Nf6 2.Nf3 g6 3.Bf4 "There is one opening that shines above all others when comparing reward payout to the input effort," says Zhigen Lin. "It is relatively quick to learn and obscure enough that even titled opponents may not have a proper antidote lined up." He is - of course - talking about the London System, popularized by the London BCF Congress Tournament of 1922. ICC presents: The London System by GM Damian Lemos Learning the London system is not hard, and it can be an essential arrow in your quiver! All you need is a set of videos by an experienced GM and, of course, a lot of practice! Damian Lemos became a chess Grandmaster at 18 and won the Gold Medal at the Pan-American Games U-20 in Colombia. -

The Oldest Books on Modern Chess
The Oldest Books on Modern Chess By Jon Crumiller © 2016 Worldchess.com Nobody expects the Spanish Inquisition. But when players respond to 1. e4 with 1. … e5, they can often be subjected to the Spanish Torture. That’s a well-known nickname for the Ruy López, one of the oldest and most commonly used openings in chess. The nickname is possibly not a coincidence; the Inquisition was active in Spain in 1561, the same year that the Spanish priest named Ruy López de Segura published his celebrated work, Libro de la Invencion liberal y Arte del juego del Axedrez. The book contained the analysis from which the chess opening received its eponymous name. Jonathan Crumiller The passage highlighted above can roughly be translated: White king’s pawn goes to the fourth. If black plays the king’s pawn to the fourth: white plays the king’s knight to the king’s bishop third, over the pawn. If black plays the queen’s knight to queen’s bishop third: white plays the king’s bishop to the fourth square of the contrary queen’s knight, opposed to that knight. Or in our modern chess language: 1. e4, e5 2. Nf3, Nc6 3. Bb5. Jonathan Crumiller On the right is how the Ruy López opening would have looked four centuries ago with a standard chess set and board in Spain. This Spanish chess set is one of my oldest complete sets (along with a companion wooden set of the same era). Jonathan Crumiller Here is the Ruy López as seen with that companion set displayed on a Spanish chessboard, also from the 1600’s. -
Multilinear Algebra and Chess Endgames
Games of No Chance MSRI Publications Volume 29, 1996 Multilinear Algebra and Chess Endgames LEWIS STILLER Abstract. This article has three chief aims: (1) To show the wide utility of multilinear algebraic formalism for high-performance computing. (2) To describe an application of this formalism in the analysis of chess endgames, and results obtained thereby that would have been impossible to compute using earlier techniques, including a win requiring a record 243 moves. (3) To contribute to the study of the history of chess endgames, by focusing on the work of Friedrich Amelung (in particular his apparently lost analysis of certain six-piece endgames) and that of Theodor Molien, one of the founders of modern group representation theory and the first person to have systematically numerically analyzed a pawnless endgame. 1. Introduction Parallel and vector architectures can achieve high peak bandwidth, but it can be difficult for the programmer to design algorithms that exploit this bandwidth efficiently. Application performance can depend heavily on unique architecture features that complicate the design of portable code [Szymanski et al. 1994; Stone 1993]. The work reported here is part of a project to explore the extent to which the techniques of multilinear algebra can be used to simplify the design of high- performance parallel and vector algorithms [Johnson et al. 1991]. The approach is this: Define a set of fixed, structured matrices that encode architectural primitives • of the machine, in the sense that left-multiplication of a vector by this matrix is efficient on the target architecture. Formulate the application problem as a matrix multiplication. -
