6 Concerning Chess Improvement, and This Book

It is well-known that the best form of training is practical play, and taking part in tournaments. In order to play better, one must play more, and with strong opponents wherever possible. However, this axiomatic advice requires a little amendment. Every game is an examination in itself.But it is an examination without precise model answers to the questions that are most important. Did we (and our oppo­ nent) handle the changing situation frommove to move correctly? Which moment was the turning point - where was the decisive mistake made, and was it exploited in the best way? 'To know that, we have to analyse the game', - the reader will doubtlessly tell us. Indeed, but it would be very usefulto compare our conclusions with those of a more qualified judge, a player who is significantly stronger than ourselves. Yo ur analysis, no matter how serious it may be, is limited by the level of your chess understanding. Suppose that you have found theplace where, it seems to you, your play departed fromthe best line, where you committed some inaccuracies and mis­ takes, and now you know how you should have played. But have you foundthe best moves forsure ? How accurate is your tactical vision? Can you be sure you have not missed any combinative possibilities for yourself or your opponent? Finally, no matter how well-developed your feeling forposition may be, are your assessments totally objective? In a word, aren't you taking on too much, and setting yourself a task that is unfulfillable? Have you missed a decisive continuation, before yo u are convinced that the position cannot possibly contain anything out of the ordinary? But even if you have an experience?!. helper on hand, you are unlikely to achieve great successes, if you only study your own games. You also have to study others' games, both classical and modern: instructive master games, typical and original combinations and characteristic plans. Added to that is the required basic knowl­ edge of opening and endgame theory. We can findal l of this (or, at least, we should be able to findit) in the traditional chess textbooks. When playing over the games given, one remembers what one has seen, and tries in similar situations to implement the knowledge obtained. How­ ever, it is hard to judge how and to what extent the material is mastered, since there is no direct contact between the book's author and its reader. In general, both methods of self-improvement - analysing one's games (not only won games, but losses as well) and working with textbooks, have their pluses and minuses, and complement each other.

But isn't it important to bring together knowledge and practical play? In your hands, you have a textbook (a schooling in combinations) and a collec­ tion of exercises (practice). In short, a self-tutor and a sparring-partner.

These positions, taken from the games of masters and grandmasters, as well as lesser players, are given immediately before the decisive moment in the game. You have to find the winning line, or, in the case of difficult positions, the saving re­ source. A few of the positions are compositions, or are taken from compositions, close in style to practical play. In the first part of the book, the positions are grouped by theme, which, of course, makes them easier to solve. In the second part, the themes are not indicated, and so the reader has no extra hints in this 'Finishing School'. However, the basic factthat all of the positions require a combinative solution is itself a sufficient hint forthe experienced player to findthe correct path. Try at firstto solve the questions without moving the pieces, and go over to de­ tailed analysis, only when you are convinced that you cannot solve the exercise in your head. The reader will no doubt notice that farfrom all of the famousgrandmasters are represented here. But the book is not intended as an anthology of combinations by the great, and the examples have not been chosen on the principle of being repre­ sentative, but fortheir instructional value. The level of the event in which the game was played has also not been used as a factorin the selection. Alongside fragments fromthe games of the most famous masters, you will meet examples fromsimulta­ neous displays and quite insignificantcompetitions. And so, in conclusion: this book, which is aimed at a wide range of chess ama­ teurs, may also be used by an experienced player, a master, or even a . Even he will find many positions that are unknown to him, and which he can use to show to his own pupils.

The author and the editors have checked all the combinations in this book with the computer. However, the book may still contain flaws. Readers who have found er­ rors are invited to notify us via email: [email protected].

8 The Alpha and Omega of Chess

Strategyand tactics. The definition of a . Classification.

Right from the very first page of most chess books, in almost every comment we encounter special terminology, without thinking much about their derivation and basic meaning. A chess game is an ideal representation of war, in which the sides (as distinct from a real war) followclearly -definedrules. The majority of the terms we use in chess are derived from military lexicon. Tactics and strategy. Attack and defence. Counter-attack. Flanks and the rear. , siege, blockade, breakthrough, pene­ tration, etc. STRATEGY is the most important part of the art of war, devoted to the prepara­ tion and carrying out of military actions, and the planning of operations. TACTICS is the art of conducting a specific battle. Because the specific battle is part of the overall (strategic) operation, tactics serve strategy, and fulfilits tasks. In this sense, should occupy itself with planning, and the selection of the targets at which our play should be directed in the given position. Tactics are the specific concrete actions which we have to carry out to achieve our desired aims. In the words of Max Euwe, the distinction is between 'what to do' and 'how to do it'. In a word, tactics serve strategy and depend on it. Compared with a war situa­ tion, the chess definitionshave a slightly different sense. Ta ctics do not embrace all concrete operations (for example, exchanges) , but only actions of a sharp, combinative character, intended to change significantly the picture on the board, or to decide the game's outcome. In this sense, it does not matter whether the tactical operation is the logical outcome of events (i.e. whether it fitsin with the strategic plan) or whether it is unconnected with the general flow of the game, and arises randomly (forexample, because of a by the oppo­ nent in a position that is better forhim) . In other words, tactics in chess do not always serve strategy - sometimes they exist of their own accord. Separate manoeuvres, aimed at fulfilling the strategic plan, are not usually regarded as part of tactics. In general, the terms 'tactics' and 'strategy', and, correspondingly, 'tactical play' and 'strategic play' are used almost as synonyms. When starting out using chess literature, it is worth remembering this change in military (and even political) terminology.

And now we turn to the play itself

Note: Throughout the book, we will use squares to the left of every diagram to in­ dicate which side is to move.

5 Geller Arguments about formulaehave no real Novotelnov connection with practical play.But these Moscow, I 9 S I definitionsare the basis forthe classifi­ cation of combinations, and, corre­ D spondingly, forthe construction of our account ofthis important theme. So far, we have deliberately chosen combinations in which every move is a . Checks are a powerfulmeans of control, of limiting the opponent's choice of replies. Calculating a combi­ nation in which the enemy king is continually chased around with checks (especially if the main line has few, if 1Jhf8+!

Other means of control are threats and captures (exchanges). De­ cisive threats can also be set up by 'quiet' (i.e. outwardly unremarkable) moves.

Moves (or series of moves) connected by a general idea and logically con­ nected with one another, are called a variation. When one side forces the other's moves , this isa forcin g variation.

Besides mating the enemy king and gaining material, any favourablechange in the position can be the object of a combination (forexample strengthening an attack, improving piece coordination, transposing into a promising endgame, etc.), and in a bad position, a combination may be the basis forsaving the game (e.g. by setting up , , re-establishing material equality, reaching a theoret­ ically drawn ending, etc.), obtaining counterplay and even weakening the enemy attack.

13 Improve Your Chess Tactics

A combination is the strongest means of achieving the aim. It is an extraordinary way of reaching the goal, a breakthrough that clarifies the situation on the board in .i short time-frame,reveals the truth about the position, and exposes falsevalues. Now let us look at combinations through the eyes of the spectator. Sacrificesand the subsequent extreme follow-ups create a strong emotional effect, whether we are watching the game in the tournament hall, or reading a book in which a game from long ago is presented. Original thoughts (not, in the final analysis, the amount sacrificed), accurate calculation, 'quiet' intermediate moves, and the final victory of a relatively small forcehave a striking effecton us. Aesthetic appreciation of a combination depends, of course, on the class of a player. A typical combination, using a hackneyed theme, can be a real revelation to one player, but little more than an element of technique to another. The main point, though, is that the scope for original combinative ideas is almost inexhaustible. This is the nature of chess. Even with respect to typical combinations, all chess po­ sitions are concrete and have their own unique characteristics, and so experience, although it helps, can never insure anyone against mistakes. There are as many combinations as there are chess positions. Afterthe reformof the moves of queen and bishop (in the I 5th- 16th centuries), the role of combina­ tions greatly increased. It is precisely in the existence and extent of combinations that other games invented by the human mind are unable to compare with chess. Thus, a combination is a forcing variation with a sacrifice, in pursuit of a positive aim, andleading to a significantchange in the situation on the board. Combinations can be classifiedby intention, and also by other formalattributes: the material which is sacrificed,the pieces taking part in the combination and play­ ing the major role therein, and the object against which the combination is directed.

However, the most important of all is the classificationof combinations by con­ tent. The MOTIF is the characteristic of the position, on which the player fastens in his search fora combination. This may be the cramped position of the enemy king, or, on the contrary, the distance by which its pieces are cut offfrom the defence, the weakness of the back rank, or of the squares in the immediate vicinity of the king, or the undefended position of a certain piece, or the lack of coordination between the pieces. The motif is nothing other than the initial signpost which directs the player's attention to the right area in his search fora combination. The THEME of a combination (sometimes called the 'idea') is the answer to the question of what the combination consists of For example, the deflection of the queen from thedefence of a (the deflection theme), the breaking of the connection between enemy pieces, the presence of pieces on a single line, etc.

14 Combinative Themes fmprove Your Chess Tactics

Deflection

In combinations on the theme of deflection,an enemy piece or which is per­ formingan important functionis forced (or induced) to leave its position, thereby exposing a key line or square, or leaving another piece undefended. The finalaim of the operation can vary.

Now we will look at some examples where the deflection is followed by a · knight . As in the previous examples, the final aim is to secure a material advantage.

47 Eliminating Defenders

So far we have looked at the idea of taking defenders out by deflecting or luring them away from the defence. In combinations with elimination of defenders, we see the more basic method of the direct capture of the pieces or pawns which fulfil a valuable defensive function. This includes combinations designed to destroy the king's defensive pawn wall.

60 Pinning and Unpinning

When pinned by a queen, rook or bishop, a piece (or pawn) is wholly or partly limited in its mobility, since it has to protect another piece, more valuable than it­ self.or just undefended, along the same line. If it is the king that stands behind the pinned piece, then that piece's mobility is restricted to the maximum extent (it can only move up the same line). If the pinned piece is protecting not the king, but another piece, then the pin may not he total, since the pinned piece may quit its post, 'in pursuit of a higher goal', leaving the more valuable or undefended piece behind it under attack.

It was allegedly Napoleon who said that 'Every soldier carries a marshal's baton in his knapsack'. Even so, neither in the wars of Napoleon's time nor later ones do sol­ diers get to become marshals. But in the army, this fairytale transforma­ tion awaits any humble pawn which manages to reach the other end of the board.

105 Miracle Saves

Imagine we are at the cinema, watching a detective film.The hero is surrounded on all sides by enemies. His situation seems desperate, and a tragic end seems inevita­ ble. But at the very last moment, when no hope seems to remain, our hero makes a miraculous escape and emerges intact from the danger. The author manages to create a scenario in which a most unlikely salvation comes to the hero, so beloved by the viewers, who do not want to believe in his finaldo om. Such miracle escapes are described as 'like in a novel' or 'like in a film'. Chess players say 'like in an ' to describe similar chessboard miracles. Indeed, we will start with a study.

118 Examination

'But almost the whole of this book is an examination in tactics', the reader might object. 'So why is only this section called an examination?' In all sections of the book, when trying to solve the positions presented, you know that there is some extraordinary tactical possibility in the position. But in the earlier sections, you have also had another very helpful clue, inthe title of the sec­ tion concerned. The previous sections arc therefore more in the nature of a rein­ forcement of the topics discussed, rather than an examination. In this examination, you will still have the general hint that the solutions are of a tactical character. The reader is offered the opportunity to judge for himself how well he has passed the test. You have before you 3 5 6 test positions.

38 The knight on d4 is attacked and has no retreat. But if the queen did not control c2, White would be mated. Therefore the queen must somehow be deflected. This is achieved with the move l...�aS!, after which White had to resign (Gliksman-Popovic, Wroclaw 1979).

39 Black, who has an extra bishop, has defended against the mate threatened on h 7, offering the exchange of queens (the c8-square is covered by the knight). White needs to findan extreme tacti­ cal solution, as his rook and knight are attacked. The move 1.nf4!, deflecting the queen from the defence of either the square h7 (in the event of 1...'i'xf4) or the 8th rank (in the event of l.. .°i'xd3), forced Black to resign (Belov­ Ongemakh, Narva 1984). 40 l...�e2!, and White resigned (Panno-Bravo, Brazil 197 5).

382 About the Author

Born in Moscow in 1923 and raised there, Ya kov Isayevich Neishtadt became a living legend in Russian chess. He was already a first-category player at the beginning of Wo rld Wa r II, but then he had to serve his country in battle. After the war he started to play in tournaments again and be­ came a master of sports of the USSR as well as a world-class player and an arbiter. But Neishtadt is best known as an outstanding chess journalist. He has written more than twenty opening books, which have been published in a dozen languages. From 1955 to 1973 he was secretary of the magazine Chess in tile USSR, and from 1977-1979 an editor of the famous Soviet 64. In 1992 Neishtadt moved to Israel with his family. There he is still writing books. Genna Sosonko, in the article 'Yakov Neishtadt at 80' in his book Smart Cliip from St. Petersburg (New In Chess, 2006) , called him 'a living treasure-trove of history, an­ ecdotes, incidents, events, memories of people, sketches.'
