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. -
Parallel Chess Searching and Bitboards
Parallel Chess Searching and Bitboards David Ravn Rasmussen August 2004 Abstract In order to make chess programs faster and thus stronger, the two approaches of parallelizing the search and of using clever data structures have been suc- cessful in the past. In this project it is examined how the use of a specific data structure called a bitboard affects the performance of parallel search. For this, a realistic bitboard chess program with important modern enhance- ments is implemented, and several experiments are done to evaluate the performance of the implementation. A maximum speedup of 9.2 on 22 pro- cessors is achieved in one experiment and a maximum speedup of 9.4 on 12 processors is achieved in another experiment. These results indicate that bitboards are a realistic choice of data structure in a parallel chess program, although the considerable difference in the two results suggests that more research could be done to clarify what factors affect such an implementation, and how.

1 Najdorf Sicilian Focus on the Critical D5 Squar One the Most Common Openings in the Past 50 Years Is the Najdorf Variation Of
1 Najdorf Sicilian will try to keep full control over the d5 Focus on the Critical d5 Squar square, and try to maintain the possibility of placing and keeping a piece One the most common openings in the on d5. Fully controlling the d5 square past 50 years is the Najdorf variation of allows white to affect both sides of the the Sicilian Defense. The Najdorf offers board. In order to assure that control, many different possibilities, starting from white wants to trade off black pieces extremely sharp, poison pawn variation that can control d5. For example, he (1. e4, c5 2. nf3 d6 3. d4 cxd4 4. Nxd4 wants to play with Bg5, in order to trade Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Qb6 8. off the Knight on f6. He also will Qd2 Qxb2! ) to extremely positional lines increase the number of his own pieces (1. e4, c5 2. nf3 d6 3. d4 cxd4 4. Nxd4 that can control d5, with maneuvers like Nf6 5. Nc3 a6 6. Be2 e5 7. Nb3 ... ) bishop to c4, then b3, and the knight on Somewhere between those two lines is f3 going to d2-c4-e3. It seems that white the following position, which I will try to has full control of the situation. So why explain. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 does black choose to create this pawn 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nf3 structure?

Grandmaster Opening Preparation Jaan Ehlvest
Grandmaster Opening Preparation By Jaan Ehlvest Quality Chess www.qualitychess.co.uk Preface This book is about my thoughts concerning opening preparation. It is not a strict manual; instead it follows my personal experience on the subject of openings. There are many opening theory manuals available in the market with deep computer analysis – but the human part of the process is missing. This book aims to fill this gap. I tried to present the material which influenced me the most in my chess career. This is why a large chapter on the Isolated Queen’s Pawn is present. These types of opening positions boosted my chess understanding and helped me advance to the top. My method of explaining the evolution in thinking about the IQP is to trace the history of games with the Tarrasch Defence, from Siegbert Tarrasch himself to Garry Kasparov. The recommended theory moves may have changed in the 21st century, but there are many positional ideas that can best be understood by studying “ancient” games. Some readers may find this book answers their questions about which openings to play, how to properly use computer evaluations, and so on. However, the aim of this book is not to give readymade answers – I will not ask you to memorize that on move 23 of a certain line you must play ¤d5. In chess, the ability to analyse and arrive at the right conclusions yourself is the most valuable skill. I hope that every chess player and coach who reads this book will develop his or her understanding of opening preparation. -

Course Notes and Summary
FM Morefield’s Chess Curriculum: Course Review This PDF is intended to be used as a place to review the topics covered in the course and should not be used as a replacement. Feel free to save, print, or distribute this PDF as needed. Section 1: Background Information History ● Chess is widely assumed to have originated in India around the seventh century. ● Until the mid-1400s in Europe, chess was known as shatranj, which had different rules than modern chess. ● Some well-known authors and chess players from that time period are Greco, Lucena, and Ruy Lopez. ● The Romantic Era lasted from the late 18th century until the middle of the 19th century, and was characterized by sacrifices and aggressive play. ● Chess has widely been considered a sport since the late 1800s, when the World Chess Championship was organized for the first time. Other ● Chess is considered a game of planning and strategy because it is a game with no hidden information, where you and your opponent have the same pieces, so there is no luck. ● Studying chess seriously can bring you many benefits, but simply playing it won’t make you smarter. Section 2: Rules of the Game Setting Up the Board ● There are sixty-four squares on the board, and thirty-two pieces (sixteen per player). ● Each player’s pieces are made up of eight pawns, two knights, two bishops, two rooks, a queen, and a king. ● There are two players, Black and White. White moves first. ● If you’re using a physical board, rotate the board until there is a light square on the bottom right for each player. -
