  • A GUIDE to SCHOLASTIC CHESS (11Th Edition Revised June 26, 2021)
    A GUIDE TO SCHOLASTIC CHESS (11th Edition Revised June 26, 2021) PREFACE Dear Administrator, Teacher, or Coach This guide was created to help teachers and scholastic chess organizers who wish to begin, improve, or strengthen their school chess program. It covers how to organize a school chess club, run tournaments, keep interest high, and generate administrative, school district, parental and public support. I would like to thank the United States Chess Federation Club Development Committee, especially former Chairman Randy Siebert, for allowing us to use the framework of The Guide to a Successful Chess Club (1985) as a basis for this book. In addition, I want to thank FIDE Master Tom Brownscombe (NV), National Tournament Director, and the United States Chess Federation (US Chess) for their continuing help in the preparation of this publication. Scholastic chess, under the guidance of US Chess, has greatly expanded and made it possible for the wide distribution of this Guide. I look forward to working with them on many projects in the future. The following scholastic organizers reviewed various editions of this work and made many suggestions, which have been included. Thanks go to Jay Blem (CA), Leo Cotter (CA), Stephan Dann (MA), Bob Fischer (IN), Doug Meux (NM), Andy Nowak (NM), Andrew Smith (CA), Brian Bugbee (NY), WIM Beatriz Marinello (NY), WIM Alexey Root (TX), Ernest Schlich (VA), Tim Just (IL), Karis Bellisario and many others too numerous to mention. Finally, a special thanks to my wife, Susan, who has been patient and understanding. Dewain R.

  • Chess Basics
    NEWSLETTER Library: Jan-2003 Morals of Chess Feb-2003 Humor in Chess Feb 15th SCC Guidelines March 2003 The History of Chess Notation by Robert John McCrary The number of books on chess is greater the number of books on all other games combined. Yet, chess books would be few and far between if there were not an efficient way to record the moves of games. Chess notation is thus the special written" language" of chess players, making it possible for a single book to contain hundreds of games by great players, or thousands of opening variations. Surprisingly, however, chess notation was slow to evolve. As late as the early nineteenth century, many chess books simply wrote out moves in full sentences! As a result, very few of those early games before the 1800's were recorded and preserved in print, and published analysis was correspondingly limited. In Shakespeare's day, for example, the standard English chess book gave the move 2.Qf3 as follows: " Then the black king for his second draught brings forth his queene, and placest her in the third house, in front of his bishop's pawne." Can we imagine recording a full 40-move game with each move written out like that! Nevertheless, the great 18th century player and author Andre Philidor, in his highly influential chess treatise published in 1747, continued to write out moves as full sentences. One move might read, "The bishop takes the bishop, checking." Or the move e5 would appear as "King's pawn to adverse 4th." Occasionally Philidor would abbreviate something, but generally he liked to spell everything out.

  • Algebraic Chess Notation
    Algebraic chess notation Algebraic chess notation is the method used today by all competition chess organizations and most books, magazines, and newspapers to record and describe the play of chess games. It replaced descriptive notation, although the older notation can still be found in older literature. Algebraic chess notation identifies each square of the chessboard with a unique coordinate. The files (the columns of the chessboard) are labelled with lowercase letters a through h, from the left to right (as seen by the white player). So the " a" file is to white's left, and to black's right. The ranks (the rows of the chessboard) are numbered from 1 to 8, starting from white's home rank. Each square of the board is uniquely identified by its letter and number. Each type of piece (other than pawns) is identified by an uppercase letter, usually the first letter in the name of that piece. English-speaking players use K for king, Q for queen, R for rook, B for bishop, and N for knight (since K is already used). Pawns are not indicated by a letter, but by the absence of a letter. Each move of a piece is indicated by the piece's initial, plus the coordinate of the destination square. For example Be5 (move a bishop to e5 ), Nf3 (move a knight to f3 ), c5 (move a pawn to c5 ). When a piece makes a capture, an x is inserted between the initial and the destination square. For example, Bxe5 (bishop captures the piece on e5 ). When a pawn makes a capture, the file from which the pawn departed is used in place of a piece initial.

  • Seven Tips on How to Study for the UIL A+ Academics Chess Puzzles by Al Lawrence Former Director, Texas Tech Chess Program
    Seven Tips on How to Study for the UIL A+ Academics Chess Puzzles by Al Lawrence Former Director, Texas Tech Chess Program The Texas Tech Chess crew enjoys the challenge of putting together the UIL’s A+ Academics Chess Puzzles test. We’ve received a number of inquiries about how students can prepare for the tests. There’s a lot you can do in a relatively short time to improve student scores. First of all, it’s important to keep in mind that, although some of the puzzles ask the student to solve a checkmate problem, there are many other types of chess puzzles on the test. The puzzles test knowledge of all the chess rules. Playing skill is also tested, sometimes challenging the student to choose the best move in a position. Each main test consists of 20 puzzles (chess diagrams). Below each puzzle are four possible multiple-choice answers, a-d, to choose from. Students mark their answers on a separate answer sheet. Let’s go through some tips about what a student needs to know. We’ll give some online resources for study. In early November, we’ll provide some sample questions on these topics to check your progress. In the meantime, you can also see the UIL practice tests and puzzles online at the Texas Tech Chess Program website: http://www.depts.ttu.edu/ttuchess/ 1. Know how to read chess moves! The puzzles are diagrams that look like little chessboards. But to choose the right answer from the multiple choices below the diagrams, you have to be able to read chess moves! Experienced chess players can write down their games.

  • How to Read Chess Notation
    How to Read Chess Notation Here's a very brief explanation of how to read algebraic and descriptive notation. The board must always be set up so a white square is in the right hand corner. This is very important and the game must start over if the board is set up wrong. I knew a master who once walked past a friend's tournament game and noticed that a black square was in the right hand corner. The game was declared invalid and a new game begun. The master came by again during the new game and put his thumbs to his head and wiggled his fingers, making donkey ears at his friend, who had been winning the first game but now was getting whomped. This unfortunate leaped up from the board with a roar, grabbed the master by the throat, and tried to strangle him. The queen starts on a square of its own color. In algebraic notation each square has a name, and that name is used by both White and Black. Diagram 7 8 7 6 5 4 3 2 1 a b c d e f g h 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 Moves The ranks are numbered 1 - 8 and the files are labeled a - h. The square a1 is White's left corner square. The name of the piece moved (except for pawns) is combined with the destination square. If there could be any confusion, add more information like the square, the rank, or the file where the piece came from.
