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. -
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. -
Of Kings and Pawns
OF KINGS AND PAWNS CHESS STRATEGY IN THE ENDGAME ERIC SCHILLER Universal Publishers Boca Raton • 2006 Of Kings and Pawns: Chess Strategy in the Endgame Copyright © 2006 Eric Schiller All rights reserved. Universal Publishers Boca Raton , Florida USA • 2006 ISBN: 1-58112-909-2 (paperback) ISBN: 1-58112-910-6 (ebook) Universal-Publishers.com Preface Endgames with just kings and pawns look simple but they are actually among the most complicated endgames to learn. This book contains 26 endgame positions in a unique format that gives you not only the starting position, but also a critical position you should use as a target. Your workout consists of looking at the starting position and seeing if you can figure out how you can reach the indicated target position. Although this hint makes solving the problems easier, there is still plenty of work for you to do. The positions have been chosen for their instructional value, and often combined many different themes. You’ll find examples of the horse race, the opposition, zugzwang, stalemate and the importance of escorting the pawn with the king marching in front, among others. When you start out in chess, king and pawn endings are not very important because usually there is a great material imbalance at the end of the game so one side is winning easily. However, as you advance through chess you’ll find that these endgame positions play a great role in determining the outcome of the game. It is critically important that you understand when a single pawn advantage or positional advantage will lead to a win and when it will merely wind up drawn with best play. -
Solved Openings in Losing Chess
1 Solved Openings in Losing Chess Mark Watkins, School of Mathematics and Statistics, University of Sydney 1. INTRODUCTION Losing Chess is a chess variant where each player tries to lose all one’s pieces. As the naming of “Giveaway” variants has multiple schools of terminology, we state for definiteness that captures are compulsory (a player with multiple captures chooses which to make), a King can be captured like any other piece, Pawns can promote to Kings, and castling is not legal. There are competing rulesets for stalemate: International Rules give the win to the player on move, while FICS (Free Internet Chess Server) Rules gives the win to the player with fewer pieces (and a draw if equal). Gameplay under these rulesets is typically quite similar.1 Unless otherwise stated, we consider the “joint” FICS/International Rules, where a stalemate is a draw unless it is won under both rulesets. There does not seem to be a canonical place for information about Losing Chess. The ICGA webpage [H] has a number of references (notably [Li]) and is a reasonable historical source, though the page is quite old and some of the links are broken. Similarly, there exist a number of piecemeal Internet sites (I found the most useful ones to be [F1], [An], and [La]), but again some of these have not been touched in 5-10 years. Much of the information was either outdated or tangential to our aim of solving openings (in particular responses to 1. e3), We started our work in late 2011. The long-term goal was to weakly solve the game, presumably by showing that 1. -
1 Domination and the Five Queens Problem
Ordog, SWiM Graph Theory Project: Domination and The Five Queens Problem 1 Domination and The Five Queens Problem What is the smallest number of queens that we can place on a chessboard so that every space on the board is either occupied by a queen or being attacked by at least one queen? How can you use graph theory to find a suitable arrangement of queens on an n × n chessboard? To find a solution to this problem, you will learn about the dominating set of a graph. 1.1 Domination • A dominating set of a graph G is a set of vertices S such that each vertex of G is either in S or adjacent to a vertex in S. • What is the biggest dominating set of the graph below? • What is the biggest dominating set for any graph G? • Can you find a dominating set with three vertices? Two vertices? One? Give an example, or explain why not. 1.2 The domination number • The dominating number of a graph, denoted γ(G), is the smallest number of vertices in any dominating set of a graph G. • What is γ(G) for the above graph? Page 1 Ordog, SWiM Graph Theory Project: Domination and The Five Queens Problem • Recall that the complete graph on n vertices, Kn, is the graph with n vertices such that each vertex is adjacent to every other vertex (they are all connected by an edge). What is γ(Kn)? • Exercise: Find γ(G) for the following graphs ([Smi88]). Look for and discuss patterns that might help come up with algorithms for finding dominating sets. -
