an extra element: enviro nment. Talent may be found in any town or school, but it is not going to flourish without the right environment. In particular, a talented player may rise to the top, or nearly so, of the group of players in which she or he regular ly competes. If that group already includes very strong players, the talented player can rise higher before having to find a new group. The present series of books provides an advanced environment for the am bitious and talented player. The notes were written by International Masters as if for each other, not talk ing down to the reader. If the talented player can think in this plane, it will be a long time b e fore he or she has to find a stronger group. The material for the books in this series is the Chess Academy Tutorial computer software. The differences between book and computer deserve some examination. First, a book is better because you don't need the darned computer; a book is portable and flexible. A book is also easier on the eyes. On the other hand, a com puter can show the position at every move, and it can achieve interactivity with the reader. Both the book and the computer have their place. The material in this book is chal lenging. An ordinary presentation w o u l d h ave m aybe o n e or two diagrams for each example, say 300 diagrams in all. Th follow such a story line, most of us, even the Experts and Masters, would have to sit at a table, moving the wooden pieces while trying not to lose place on the page, but that takes away the portability of the book. Except for less eyestrain,
the player might as well be at a com puter. In this series, we include more than twice as many diagrams as is cus tomary. The reader is invited to use the diagrams instead of a board, and to fill in the gaps mentally. This is a book that can be exploited just as readily on the subway, or in a quiet corner of the garden, as in the study. Each diagram represents a point of departure. At each diagram, the reader should pause and consider the future. In general, the result with be a striking move, sometimes even bril liant, or an important strategical mo ment. The letter W or B next to the opening diagram of each example in dicates who has the move. I do not claim any order in the presentation of the material. On the contrary, order has been spurned. The material could have been or ganized into topical chapters with tit les such as "Endgame: Inducing Weaknesses". But I noticed that in the computer tutorial, my eye would flick up to the heading, and I would have a big hint as to the solution. But that is not what happens at the chess b o ard or i n r e a l l i fe. N o b o dy whispers in our ear "you should in d u c e w e a k n e s s e s b e fo r e y o u simplify" or, o n the contrary, "you don't have time to induce weak nesses, he will attack, so simplify right now". So the examples are in a moderately random order. For the benefit of those who like the hints (either before or after), the book begins with a graphical index of themes. In summary, this book is intended for ambitious players who want to learn. The way to do it is to work

through the examples, considering the course of action implicit in each d i a g r a m before c o n s i d e r i n g t h e material which follows it.

The strength of the bishop pair often lies in the possibility of exchanging one of them at any appropriate mo ment. In this case White accepts the position with oppos ite-coloured b i s h o p s because the threats to Black's king will be irresistible ( Flohr S.).

White has two bishops, but the light square one is restricted by his own pawns. If Black manages to exchange the dark-square bishops, he will have a strong knight against a weak b i s h o p .

It is far from easy for White to realize his advantage of two bishops, be cause Black's knight at d5 is strong and well entrenched. Making the most of the tactical peculiarities of the position ( undeveloped black pieces and a weak eighth rank), White seizes space on the queenside.

The exchange of heavy pieces is, as a rule, favorable for the player with the bishops. But sometimes it is expedient to preserve a rook to incubate weaknesses in the opponent's camp.

The mobility of White's bishops is limited and his pawn structure on the queenside is not resilient enough - so Black has the positional advantage. Black employs a typical plan against the two bishops - he starts by restrict ing one of them and then he exchan ges the other, after which he strives to exploit the weaknesses in his opponent's camp.

White's plan is standard for such situations: to excha nge major pieces, seize space (f3, e4), transfer the king to the center and induce weaknesses on the kingside. The advanced bS-ft facilitates the plan's last stage. So it is better to avoid pawn weaknesses in a fight against the two bishops.

This hastens defeat. Against passive defense, the winning plan is to put the king at c4 and exchange dark square bishops. As a result the light square bishop would be far superior to the black knight, especially con sidering the weakness of the a6 pawn and the placement of B lack's kingside pawns o n light squares. This puts in relief the main advantage of the bishop pair: at a critical moment one of them may be exchanged, leav ing only the more useful one (Flohr)

Despite the reduced n umber of pawns, Black's position is not safe. White has an interesting plan: to weaken f5 with the pawn sacrifice h4h5, then tie down Black's pieces to the defense of the pawn and transfer the king to c6 ( weak square d6). Black's only defense was to trans fer the knight to the support point c5: l...�t7-d8, b. �d8-b7-c5, whence the knight can control important central points and play an active part in the defense.

9 White's bishops exert strong pres sure on Black's queenside. White plans to induce then attack weaknesses on the queenside. Black lacks an active plan of counterplay (playing on the kingside can only produce new weaknesses i n his camp). Black's only stronghold is the d4 point. If White drives the knight out of there (e2-e3), Black will get counterplay against the weakened pawn on d3.

Black breaks the rule that an ex change of bishops does not favor the p layer with the pair. But every rule has its exceptions! After the trade, White's problem is how difficult it is to resist the advance of Black's pawns in the center.

White has the positional advantage due to his two active bishops which can shoot through the center and the enemy queenside. Black's knight is misplaced at d6, so he is unable to mount pressure with his rooks along the d-file and attack the weak d3 pawn. Moreover, the knight has no good protected square to operate from.
