The spirit of Indian Defenses is based on flexibility and harmony. Most of the lines are positional, not tactical in character. While playing Black, you have to accept that occasionally you will not equalize, or get surprised or out-prepared. Learning the material from this book should sharply limit the extent of such instances, thus improving your overall results. Finally, I have an important piece of advice: remember about color strategy! The Bogo-Indian is mainly based on dark-squared control, while the Nimzo-Indian does so on the light squares. In case you forget what to do, this may prove a very useful guideline when choosing a move.

Het schaken is bijzonder geschikt voor de totale ontwikkeling van elk kind. Omdat jonge kinderen de figuren op een schaakbord intrigerend vinden, bedacht Christel Minne (kleuterjuf en schaakcoach) een leuk en historisch prentenboek in rijmvorm om kleuters vanaf vier jaar mee te nemen in de wereld van het schaken. De tekeningen in het prentenboek zijn grappig en hebben als doel een visuele ondersteuning te bieden om de schaakregels te memoriseren. De bijhorende toolbox biedt bovendien tal van spelletjes en tips voor kinderen, ouders, grootouders, leerkrachten en therapeuten die het schaken willen (aan)leren. Ken je als volwassene niets van het schaken, dan biedt dit boek gezellige en ontspannen momenten om samen met je (klein) kind of een groep kinderen aan de slag te gaan.

This book is an expansion of Pandolfini’s commandments -  The author came up with 200 axioms, one-liners and mantras.  This list of 200 is an amalgamation from various sources including previous coaches. Things I’ve read, things I’ve seen in videos, conversations with other chess players and, of course, brutal losses over the board. I hope this list serves as primer for you before you go into battle, so that you remember key patterns and ideas, and also helps elevate your state of mind to that of a warrior going to war.

·           You may think such checkmates are a piece of cake and too easy. But you’ll see that some are not as simple as you may think.     And always remember: here in the book it’s written in big letters, “Mate in up to two moves”. In the game, though, there’s no such writing on the board and you have to see the mate yourself, preferably a few moves ahead.     Therefore it’s important that you know as many mate patterns as possible. I hope I can show you some that you did not know already or that you would not always recognize in a game.     Please take this training seriously; an important part of the road to playing better chess.

T Sound aggression against the Dutch Defence   Promises good attacking chances and avoids learning reams of theory about the Leningrad Dutch, the Stonewall or the Classical Dutch, opening set-ups our opponent knows everything about?    This book explores such a system for White with a complete repertoire based on the Staunton gambit.    A repertoire for White, with attention for various alternatives White may choose from along the way, and an in-depth analysis of all of Black's responses.

This book is a complete Black repertoire starting 1.e4 e5 2. Nf3 Nc6 3. Bb5 a6, the exchange variation being the first chapter. It provides you with a lot of insights into this remarkable variation, the Ark, and entertains the reader with spectacular, resourceful lines to illustrate the ideas.  This book should also be interesting for those who just enjoy chess in general, not just for the fans of this line seeking new ideas! You don’t need to memorize everything to be able to play the variation successfully. Longer lines merely tend to be examples of how the game might develop, which help to enhance your understanding.

I have aimed to find a good balance of verbalexplanations without ignoring the hardcore variations you have to know. In caseyou find some of the analyses a bit too long, don’t be discouraged! They havebeen included mainly to illustrate the thematic ideas and show in whichdirection the game develops once the theoretical paths have been left. That’swhy I have actually decided to cover 37 games in their entirety, rather thancutting off my analysis with an evaluation. I believe that model games help youto better understand an opening, but certainly also the ensuing middle- andendgames. Just as in the The Modernized Sveshnikov,also in this book I have made frequently use of correspondence and enginegames. With a lack of over the board (elite) tournaments, most elite playersmade their switch to the world of online chess as well. These games with ashorter time control are often full of mistakes, but the opening stage is stillrelevant. Hence, I have decided to include these online games whenever Ithought them to be a useful addition to our repertoire. With the completion of this work and TheModernized Sveshnikov, I think I have succeeded in offering the reader acomplete, ambitious, and sound Black repertoire against 1.e4. I am incrediblysatisfied with the result of this work, as I think the mix of new ideas, beautifulvariations, model games, extensive analyses and explanation of key concepts willinspire many chess fans. I would like to wish you all an enjoyable read andhope that you will be able to apply some of my recommendations in your owngames. You no longer have to fear any Anti-Sicilian!  Robert Ris Amstelveen, The NetherlandsSeptember 2021

In "The Duel", Alessandro Bossi and Claudio Brovelli go deep into the lives ofthese two legendary World Champions, who have left their mark in an unforgettable manner on their epoch (the first forty years of the 20th century) and whoremain – in part, due to their very different personalities and relationship withthe game – inimitable examples for all the chess-playing generations to come.The choice to present in parallel the two biographies (in my opinion quite rightlyso), shows clearly and effectively similarities and differences, not only in the styleof play, but also in the approaches to life of the two protagonists.With very precise historical descriptions and presenting the events in chronological order, the authors accompany us on a journey alongside the lives of thesetwo legends of chess. In this fashion the personalities emerge, in many ways antithetical but equally fascinating: Capablanca, friendly and charming in society,precocious, genial and nearly invincible on the chessboard, and Alekhine, whocombined a wonderful talent with a capacity for work, a competitive attitude andan energy which was truly enviable.

Volume 2 is divided into eight chapters. Unlike Volume 1, it is possibleto mix the order in which you study these chapters , but not to study the gameswithin each chapter out of order, since the examples build upon each other incomplexity. I suggest that the chapter on “Passed Pawns” should be studiedfirst, because many of the various middlegame structures can ultimately giverise to a passed pawn in the endgame. Work carefully through these examples,because masters use pawn structures even in the opening to predict the propertiesof endgames which can potentially arise – this is a widely neglected aspect andcan be a strong weapon for you!

The purpose of this series is to introduce the reader to advanced training concepts, using the same methods of presentation and instruction that were taught to great players by famous trainers that they have worked with. The series will commence with the The Passed Pawn and we will examine how to handle such pawns.Every chess player who wishes to improvehis level in the difficult subject of chess is obliged to study methodicallyand understand the existing principles that govern the theory of the opening,middlegame and endgame. Most chess players focus more on the study of openingtheory than other aspects of the game. The reasons are probably clear: openingtheory is easier to learn and can provide immediate results, although this isbased more on the opponent's ignorance than our own abilities. Even for a chesstrainer, it is easier to teach some variations from this or that opening or aset of simple tactical motifs than to engross himself in the exposition ofmiddlegame and endgame theory. Yes, middlegame and endgame theory does exist.The great difficulty in approaching it lies in the fact that it does not followabsolute and clear-cut paths, but rather involves deep research in the ideasand logic by which specific types of positions are treated. Moreover, unlikeopening theory, the theory of the middlegame and the endgame does not changerapidly based on modern developments; it remains almost intact through theyears. In view of the above, any chess player who wishes to follow a chesscareer or simply become a better player must refrain from the commonplace andassume a different approach. He must develop a good understanding of middlegameand endgame theory, so as to be able in his games to proceed in a proper wayafter his chosen opening has reached its conclusion. The chess player candifferentiate himself only in the opening; there, each one of us brings forthhis own beliefs and convictions, and in general his own experiences andreferences. Objectively, no opening loses ? but also no opening wins. Theopening is just the beginning of the journey and serves to offer us acomfortable start. But to reach the end of this journey successfully we have tocount on our knowledge and experience, as regards middlegame and endgametheory. Endgame theory teaches us two fundamental issues. First, how to extractthe maximum from a basic theoretical position with little material, where theexperts, from practice comprising thousands of games, have reached definiteconclusions. Second, the way in which we can handle an endgame, depending onthe material remaining on the board, and the ideas and plans we should employ.This second issue is significantly more difficult to master because, apart frommaking full use of the first one (we must be aware of the possible outcomes ofthe endgame in question) it is greatly influenced by our experience andunderstanding, which are basically derived from the images and impressions wehave from related positions. A primary role is played here by the effort wehave invested in studying. In middlegame theory, things are even tougher. Weare obliged to study various types of positions with specific strategic andtactical attributes, so as to understand the underlying ideas and be able toemploy them ourselves in similar situations. While many chess players havestudied these topics and acquired knowledge, it is the application of thisknowledge in practice that helps differentiate between them. Chess is not asimple activity, but it becomes so much more attractive when we acquire thisknowledge.

Welcome to Volume 2 of Cheparinov's 1.d4!.In the second part of the series, I amsharing my knowledge about the Slav Defense. I am confident that the bookcontains many new and interesting ideas and I have tried to provide you with thebest practical options. Objectively speaking Black looks good in many lines butin practice things may look different. While I cannot promise you a bigadvantage in each line, I do believe you will have the best practical chancesduring the game. Writing the second volume was verychallenging for me. The Slav encompasses a wide but solid body of theory. Blackhas plenty of options and finding advantages and practical chances was not easyat all. In any case I believe that chess players from amateurs to very strongplayers will appreciate this book. While the Covid pandemic gave me a lot offree time to concentrate on the book, I am very happy to see that manytournaments are back. This means that my book can be useful, and you mayactually be able to apply some of the ideas in your games.  The best way to use this book is to first examinethe lines on an actual board and then check them with an engine. I hope thismethod of study increases your understanding of the positions that arise fromthe Slav. This book can be a very important starting point for building your1.d4 repertoire.Ivan CheparinovMarch 2022

This book takes a closer look at the Classic mistakes by amateur playersinclude: 1. Moving a piece too often in the opening. This is one of themainstays which we think relates at least partly to the desire to createsomething in the opening, when we would be better advised to focus on simpledevelopment. 2. Impatience. Sometimes amateur players are too eager to changesomething when there really is no need. 3. Overgeneralizing. One of the biggestdifferences I’ve noticed when comparing professional play to amateur play is thatthe former is much more about concrete calculation - you go there, we go hereand so on - whereas an amateur player will have a tendency to overgeneralizewhen thinking about a position, perhaps because they are not used to the basicart of calculation. 4. Cutting variations off too quickly. Amateur players donot extend their calculation far enough, and thus superficiality tends to kickin. These and other mistakes are explained in the book. Of course itshould be noted that professional players also make these kinds of mistakes.

This book contains games from every singlefemale World Champion, as well as young up and comers, top seasonedprofessionals, streamers, and even a section at Beth Harmon from the recent famedQueen’s Gambit hit show. This book is not just for girls and women,however. Any chess player can learn from these games and discover female chesshistory, both from the famous players in the past right up to the present day. How have these games been selected?It is at this point I can mention the realreason- my UK Girls chess project called ‘She Plays To Win’ (SPTW). This group has officially been going sinceApril 11th 2020. I had the idea even a few years before, but I wasnot sure how it could be set up. The unfortunate events of worldwide lock-downprovided the answer, as the switch to being online allowed me to offer zoomlessons for UK girls as well as weekly girls tournaments on the Lichess server.I do this for free and parents have never paid anything to get involved. Each week I cover a top female player andwe analyse the game. Over the past year I have built up a large collection ofgames and tactics, which I felt could be published. It is the most up to datecollection about women’s chess covering a variety of ages and levels. After just one year, I have over 360 girlsacross the UK signed up, and a further 150 beginners in our new beginnersprogram. I hope this is just the beginning.

Talloze onderwerpen zijnmooi beschreven en keurig uitgewerkt. Maar bij het bestuderen van partijen vanschaakstudenten, of het nou talentvolle jeugd was, of volwassen clubschakers vandivers niveau, viel me één aspect op dat ik als volgt zal proberen te beschrijven: nadatde klok is aangezet en de partij is begonnen, wordt de opening gespeeld. Veel spelers blijken redelijk goed op de hoogte van de theorie. Onvermijdelijk komt het moment waarop één van beide spelers afwijkt, waardoor beide spelers op zichzelf zijnaangewezen. In de fase daarna moeten de spelers hun weg zien te vinden in eenwirwar van varianten en plannen. Zij mogen de tactiek niet uit het oog verliezen,maar bovenal zullen zij een strategisch plan moeten bepalen. In deze fase viel mij –door de bank genomen – op dat veel clubschakers over het algemeen de momentenwaarop tactiek een rol speelt, goed in de gaten hebben. Laten we zeggen dat ergemiddeld om de vijf zetten tactiek in de stelling zit. Echter… die andere vier zettenmoeten zij toch zelf verzinnen! Maar hoe moeten zij dat doen? Waar moeten ze opletten? Welke principes dienen zij te hanteren. Hoe zien ze of een bepaald strategischkenmerk dominanter is dan een ander?Als ervaren speler en gediplomeerd schaaktrainer kon ik er meestal wel een vingerachter krijgen waar het ergens mis ging. Dat was bij elke speler telkens anders, maartoch slaagde ik er soms in om een “grootste gemene deler” in de partijen van iemandop te sporen. Daarmee was ik er nog niet. Want elke partij was natuurlijk verschillendmet de partijen die nog gingen komen. Hoe kon ik deze speler daadwerkelijk vooruithelpen hiermee? In deel 2 komen de belangrijke Pionnenstructuren aan bod!

The idea behind this book is for you to‘play’ as in a real game, and it is my job to ensure you have a pleasant timewhile training. I suggest you take at least an hour and a half for eachgame and as your coach I will indicate when to guess the moves. Sometimes therewill be suggestions — including tricky ones — to measure your concentrationlevel. The ideas behind the moves are always explained. Points are awarded forthe ‘right answers’ as well as for some other moves, and at the end there is ageneral assessment plus a review of some of the things to be learned from thegame. During my coaching period I was able to witness how motivating it is forkids to receive points for the right answers, their ‘lives are at stake’ whenthey try to find the answers, and it is a challenge much appreciated by them.Later I also noticed a similar effect with adults although, unlike the kids,the older students try to hide it. The final score is not that important; it isnot scientifically based. But of course the more points you get the better you‘would have played’. The effort you put into trying to find the best moveevery time is what matters most. I firmly believe it really helps to learn alittle more about playing chess with every game. The methodology recommendedfor solving the exercises is the ‘old-school’ one of using a piece of paper tocover the text and scrolling down the page as you advance.

The revolutionary Wilhelm Steinitz(1836-1900) considered himself to be in the vanguard of an emerging, late-19thcentury ‘Modern’ school, which embraced a new, essentially scientific vitalityin its methods of research, analysis, evaluation, planning, experiment and evenbelligerent fight.Steinitz, who dominated the chess world inthe shadow of a more directly attacking, openly tactical and combinative,so-called ‘romantic’ age, established a much firmer positional basis to chess.A pivotal change!This book follows that story, both beforeand beyond Steinitz’s early ‘modern’ era, focusing closely on the subtly variedways in which the world’s greatest players in the last two centuries have thoughtabout and played the game, moving it forward. The author reflects on all sixteen ‘classical’world champions and others, notably: C-L. M. de la Bourdonnais, Adolf Anderssen,Paul Morphy, Siegbert Tarrasch, Aron Nimzowitsch, Richard Réti, Judit Polgar andthe contemporary Artificial Intelligence phenomenon, AlphaZero.Be inspired by this exploration of the ‘modern’game’s roots and trajectory!

The book that you are holding in your hands is a continuation of the famous Kuzmin series. The two prior books concerning the chess creativity of Alexander Morozevich and participants in the Candidates tournaments was written for rather experienced players. That last book on the Candidates recently won the FIDE Chess Book Award of the Year 2018.This book is different in that ¿Together With Mamdeyarov¿ has been written primarily for chess players with an Elo ranging 1400¿2100. While working on the book I followed two objectives. First to help the players¿ improvement and secondly to closer acquaint the readers with the creativity of one of the brightest contemporary grandmasters. If I were to characterize Mamedyarov¿s play in one word I would use the adjective ¿powerful¿ and if I were to use two words, then perhaps ¿power chess¿. Namely this energy and power are the dominants of his creativity with his opening preparation being only a supplementing factor.¿Together With Mamedyarov¿ is not a collection of his selected games but it is primarily a study-book. It contains test positions taken from games of the famous Azeri grandmaster with detailed comments on the solutions to the tasks. In this book the solutions have been placed right after a diagram with a test except for the six positions given as a warm-up in the beginning of the chapter one. For those of you who work without the assistance of a coach would recommend that you cover the answer with a sheet of paper to avoid spoiling the benefit of solving the problem. This book is dedicated to all young chess players aspiring to improve but i also hope that it will be interesting for admirers of the Azeri ¿number one¿ chess player¿s creativity and his fans. Further we hope this book will be useful for coaches in their work.

Your opponent plays a gambit against you. How dare they!? But how can you punish them?Spanish Grandmaster Salgado has taken a close look at a wide variety of 'Gambit Lines'. Many gambit lines, where one or more pawns are sacrificed for the initiative, have to be taken seriously, but Ivan has succeeded in finding many new ideas and theoretical improvements. The result is the neutralisation or refutation of most of these common and well known 'Gambits'.This book is simply a must for anyone who wants to be fully prepared to engage in battle against a 'Gambit Player'. If you are a gambit player yourself, you need to read this to prepare yourself for new challenges to your systems.

I would like to thank you for purchasing this book, I really appreciate it. It also means that you found an interest in my work of trying to crack the Ruy Lopez. As I said in the introduction to the first volume, I had no idea what I was signing up for when deciding to write a book on Ruy Lopez. This opening has such a rich history and good reputation that proving advantages in many lines is nearly impossible. Writing the first volume on this opening was a Herculean effort and I thought "it cannot be more difficult". After all, I was covering such solid variations as the Berlin and the Open Spanish. Well, I got surprised again! I am not exaggerating when I say that writing the second volume was at least as hard as writing the first one. This second volume on the Ruy Lopez consists of two parts. In the first part I focus on modern systems with …Bc5, attempting to dissect both the Archangelsk and Moller Variations. These two variations have quite a rich history but in 2020 there have been several developments. If I had to name one person that contributed the most to the developments in those lines it is, without a doubt, Fabiano Caruana. His encounters in the Candidates Tournament in Ekaterinburg, then his theoretical discussion in those lines with Leinier Dominguez, revised my opinion on many of those lines and led to interesting discoveries that I analyze in this bookIn the subsequent part I discuss the Closed Ruy Lopez. It is easily one of the most popular openings throughout the history of chess with many games occuring as early as the 1800s. I suggest going for 9.h3 which usually leads to a positional battle. I present new trends and find new paths and ideas in such evergreen variations as the Zaitsev, Breyer, Chigorin and others. Additionally, I attempt to crack the Marshall Attack by suggesting the Anti-Marshall lines with 8.a4. I must admit that I thought that it would be a pretty easy task to analyze those openings having some prior analysis and experience with both colors. However, time after time I was encountering new challenges and new ideas from both sides that I had to resolve. My conclusions, based on careful analysis with the most powrful engines currently available is presented in this book. This book completes my series on the Ruy Lopez. I would like to take a moment and recall what I said in the introduction to the first volume. When both sides play very good and sound chess, it is normal that games end in a draw. It is especially true for such sound openings as Ruy Lopez. I do not attempt to dismiss one line or another because somewhere with best play Black can make a draw by force on move number 30, playing sometimes ridiculous moves that are only found during the analytical work. Over the board the reality is way different – practical aspect plays an important role in chess. Some positions are easier to play, some harder. Similarly to what I did in the first volume, I try to offer the most playable positions. I do not mind if the positions are equal, provided it is easier to paly with White or the chance of an error by Black is quite large. Sometimes I go into forced variations (e.g. in Moller Defense or Archangelsk Defense), sometimes into more positional battles (like in the Zaitsev) but I truly believe that the positions I aim to reach have potential and are tricky for Black. With proper knowledge I think White can put pressure on Black in the Ruy Lopez. I hope that you will find my approach to tackling the Ruy Lopez interesting. I am aware that there is only so much I can analyze and someone may say that I did not analyze some positions deeply enough but that is the nature of chess – possibilities are pretty much unlimited and there will always be theoretical debate!Finally, I wish you, dear Reader, good luck and I hope you can successfully use the ideas that I present in this book in your games. Dariusz Swiercz February 2021.

This is the final volume in the series 'Opening Weapons'. In this book, Milos covers the Benoni, an opening that had been under a serious cloud. The author found many new and unexplored ideas, convincing us that it will inspire the Benoni player to reload his favourite opening and use it for their own benefit!

Dit is het eerste deel van de nieuwe serie Sleutelconcepten in het Middenspel. Het idee is om middenspelen te behandelen waarin een bepaalde structuur of essentieel thema cen­traal komt te staan. De gedachte om deze serie te beginnen, sluit aan bij de andere serie Begrijp wat je doet omdat het streven is om het inzicht van clubschakers te verbeteren. Het spelen van een opening dient volgens de auteur ‘opgehangen’ te worden aan stereotiepe ideeën en concepten behorende bij die structuur. Het grondige uitdiepen van midden­spel­structuren gaat te ver bij openingsboeken, vandaar dat het logischer is om dat te gaan doen in deze complementaire reeks. In dit boek wordt het Egelsysteem uitgebreid besproken. Behalve dat de speelwijze deel uitmaakt van het repertoire van de auteur, verdient deze zeer typische spelsoort het om ruim onder de aandacht gebracht te worden. Hoewel in het tweede deel van de trilogie over het Siciliaans de egel al zijn intrede heeft gedaan, kan het ogenschijnlijk kwetsbare, maar o zo verraderlijke diertje in dit boek op uitgebreide wijze zijn stekels recht overeind zetten!
