Foreword This is a unique training program that aims to help intermediate and advanced players by offering a large number of examples carefully selected by the author, German grandmaster Karsten Muller. While there are many books and software programs available to assist chess players in improving their tactical ability, there are relatively few that focus on strategic and positional considerations. Working through these positions and exercises is a great way to improve your positional understanding. I recommend it! Susan Polgar New York, May 2008

Introduction Why is it so much easier to find books that focus on tactical exercises rather than positional tests? One reason is that it is easier to locate suitable examples of tactical combinations - at least for me. Moreover, the computer can be used to check the accuracy and uniqueness of the solution. With positional exercises, different computer programs may favor different moves and completely disagree about the evaluation of a given position. This is, of course, never the case when a clear-cut tactical solution exists. In a way, this problem is similar for humans, making it difficult to find examples with unique positional solutions. Therefore, in the tests offered in this book, when I think that different moves also deserve points, I have mentioned these as well . I suggest that you begin with the introductory chapters o f motifs, but you can, of course, start with the exercises as a warm up. I f you are able to solve them quite quickly, then you should tum to the tests. You cannot expect to solve the puzzles on positional grounds alone. Positional motifs do not exist in a vacuum and con crete calculation almost always plays a role. So use your intuition to judge how far you must calculate to get ful l scores. Sometimes it is sufficient to find the first move, at other times you must calculate several moves ahead to ensure that your idea really works. Themes l ike "counterplay" or "opening the position" tend to be more tactical of course, but do not make your decisions on these grounds alone. Always let your intuition be your guide in any given position. You should repeat the tests after some time to train your memory and to recognize the patterns more readily. I hope that after studying this book, you will look at positional matters afresh, e.g. evaluate each exchange of a piece carefully (this problem is extremely important, believe me), look at the plans and ideas of your opponent and add the positionally desirable move to your list of candidates before you start calculating variations. Many thanks to Hanon W. Russell for adding many explanations, Susan Polgar for her foreword, Mark C. Donlan, Helene Romakin, N ikolas Lubbe and Steve Goldberg. Special thanks to Jacob Aagaard for testing the exercises. I wish you plenty of fun with the puzzles and I hope that your overall perfor mance improves! Karsten Miiller Hamburg, May 2008

Motifs Good and Bad Bishops
The bishop can only move on half the squares of the chessboard and this has many positional impl ications. I f one bishop is exchanged, the other is also weakened, as the enemy pieces can find a safe haven on opposite color squares of the remaining bishop. So the bishop pair is an important weapon and you should not give your opponent a strong unopposed bishop. This is especially true when an attack with opposite-col ored bishops is possible (see Part B).
Ho/lis,Adrian Swayne (2606) Hovde,Frank (2534) Corr. 1 99 1 (8)
A) Bad Bishop
Trying to restrict and finally dominate minor pieces is an important part of chess strategy. Pawns are usually used to make the bishops "bite on granite." [n Hollis- Hovde, the d3-bishop bites on the f5-h7 pawn chain, while the e3bishop is restricted by the d6- and c5pawns. Conversely, Black's a6-bishop cannot be simi larly restricted. These pawn chains are the active strategy to restrict an enemy bishop. Of course, especially long pawn chains in the cen ter can restrict the bishop. One famous example is the c8-bishop in the French Defense after l .e4 e6 2.d4 dS 3.e5. In our first example, White's dark-squared bi shop i s permanently bad, as the doubled c-pawns and the blocked f4pawn form a cage. The light-squared bishop is only on a bad square, but it will get stuck protecting c4 if White does not play actively. So 16.j},xf5!? is White's best bet.

B) Attack with Opposite-Colored Bishops
Pure opposite-colored bishop endgames have a very d ra w i s h n ature ( s e e Dvoretsky s Endgame Manual o r Fun damental Chess Endings). However, when more pieces come into play, then the rule is that the side with the attack (resp. initiative) is favored by the pres ence of opposite-colored bishops, as the defending bishop cannot contribute to the defense: White's powerhouse on d4, combined with the attacking rooks, decides the issue: 26 4)d5! 26.§g3?

C) The Bishop-Pair
-
Two bishops are usually very strong. Jonathan Rowson describes this in The Seven Deadly Chess Sins (page 1 30) as fol lows: "Although the pair of knights can be very effective, we don't see them as 'a pair' because there is nothing one knight can do that t h e other can ' t i n principle . . . There may b e someth ing good about 'the two knights' in a par ticular position, but this is purely acci dental, for there is no reason in prin ciple why a pair of them should be more than the sum of their parts. On the other hand, one bi shop makes up for the shortcomings of the other, and takes care of its own shortcomings in the pro cess. So what happens when you cap ture the opponent's bishop is not only that you remove one piece of value, but that you 'weaken' the other bishop too."

A single bishop can operate on both wings simultaneously, so it is easy to understand that the bishop-pair are a tactical powerhouse (especially in open positions) and are a strong endgame weapon. Therefore, it is no wonder that many positional operations aim to ob tain the bishop-pair:

Restricting the scope of the enemy pieces is a very important positional strategy. Studying the games of players like Karpov and Kramnik will allow you to see this concept in action and give you a better understanding of it. There are different degrees of domination: zugzwang is when all the enemy pieces are restricted, but just one dominated piece can spell trouble, as we will see in Topalov-Leko. However, let's first look at the general strategy:

Motifs Outpost
An outpost is a weak square that can not be controlled by an enemy pawn, but which can be occupied by a piece supported by its own pawn. Especially the knight needs strong anchor squares: Gurevich,Mikhai/ (2694) lvanov,Mikhail (2454) France chT ( 5 .2), 30.03 .200 1

White's knight is the key to the posi tion. When it manages to land on c4, then converting White's material advan tage will be j ust a matter of technique: 24.�gll �a6 2S.�f3 Jlg7 26.�e2 �b7 27.§d3 Ah61 28.�d2

The ChessCafe Puzzle Book 2 Opening the Position
The most important way to exploit a dynamic advantage is to open the posi tion, either by exchanging pawns, open ing files or using pawn levers. Finding the right moment and means is often crucial, as opening the position is not an end in itself and you must ascertain that you profit from it rather than your opponent.

Black to move! (Two points) Improving Piece Placement
You can use different methods for find ing candidate moves. You can ask your self questions such as: what was the point of your opponent's last move? What is your plan? Do you have any pawn breaks? etc. This chapter deals with improving the placement of your pieces, and one way of doing this is by talking to them: Tisdall,Jonathan (2500) Lechtynsky,Jiri (2435) Osterskars op (9), 1 995
Imagine you are White. B lack has no threats, and it is a relatively quiet ma neuvering position, so it makes sense to open a dialogue with the white pieces. The white king will tell you that it wants to be more central ized. The rook is al ready very happy on c2, as it can use its power on the second rank for defense and the c-fi le to restrict B lack. The knight will say that it is already on a decent square, but that there are even greener pastures on c5. And, voila, you have unearthed the solution: 31 .4)d2J Now B lack l oses a pawn by force. 31 . . . E! b 5 3 1 . . . f! b6 3 2 .lL\e4 4Ja6 3 3 . 4Jc3 +- . 3 2.4)e4 �e7 33.4)c5 4)d5 34.4) xa4 �d6 35.�e2 b6?J 36.b4J and White went on to win. The next i m portant method 1s M a k o go n o v ' s r u l e , a s quoted in Dvoretsky's Positional Play: "In posi tions of strategic maneuvering (where time is not significant) seek the worst placed piece. Activating it is often the
31
The ChessCafe Puzzle Book 2 most reliable way of improving your position." In a way, this is a special case of talking to your pieces:
Hector,Jonny (2562) Aagaard,Jacob (2359) 24th Politiken Cup, Copenhagen (3), 1 7 .07.2002

White's d2-knight is not contributing much to the game at the moment. So let's consider where it wants to be. What is the k n i g h t ' s "dream s q u are?" Khalifman concluded that b5 would be strong and regrouped accord i n g l y : 24. labcl h 5 ? 1 2 5 . 4) b t l 4) e8 26.4)c3 "I#Je7 27.4)b5 The knight has arrived and B lack's position collapses: 27 . . . a6?1 27 . . . .£lg6 2 8 . a x b 6 a x b6 29.§al ± . 28.4)c3 bxa5 29.�xa51 The c4-c5 break will open the position for W h i t e ' s b i s h o p s . 29 . . .

Motifs key to this position is whether any p i e c e s s h o u l d be e x c h anged. You should first try to make progress with the full army and only then try to de cide if any exchanges are favorable. Here the rooks can be exchanged, as the queen and knight form a powerful tan dem, which is often stronger than queen and bishop according to Capablanca's theorem. It is important to make sure that B lack's queen will be restricted and unable to launch a counterattack against White's monarch. ( 5 5 . . . 'it'h6 56 . .§ c8

Motifs Counterplay
Playing too passively is one of the sur est ways to lose at chess. If your oppo nent has the initiative, you should try to take the sting out of it. One impor tant principle is that an attack on the flank should be countered in the cen ter, as in the following typical Hedge hog example:

The ChessCafe Puzzle Book 2 Positional Exchange Sacrifice
In order for a positional exchange sac rifice to be successful, you should have one or more of the following fonns of compensation: one or two pawns, an attack against the king (preferably with an unopposed oppos i te - c o l ored bishop), the bishop-pair, a strong un opposed bishop, strong anchor squares (especially for the knights), a strong passed pawn, a mobile pawn majority, a strong blockade, many weaknesses i n the enemy camp that must be protected by the rooks, and last but not least no Iong-tenn prospects for the rooks. The latter is quite important, as the rooks tend to become stronger in the endgame, when there are fewer pawns and more open l ines. Also, you do not want to exchange too many pieces and pawns. Let's start with two typical cases:

U nd ersta n d i n g w h e n to e x c h a nge pieces (and which pieces to exchange) is very important. Do not underestimate this! Some guidelines are: I ) What remains on the board is more important than what is exchanged. 2) Do not exchange pieces if you have more space, but instead try to further restrict the enemy pieces. 3) Exchange pieces when ahead ma terial and exchange pawns when be hind in material. 4) Exchanging queens usually dra matically changes the nature of the position, as endgame themes begin to dominate, and these are quite dif ferent from the usual middlegames.

The key to the position is Black's bad bishop on e7 and White's initiative on the l ight square s : 16.Jlxf61 ± This weakens B lack's kingside pawn struc ture and purifies the favorable imbal ance, which is often good. This is also a good example for rule # I : what re mains on the board is more important than what is exchanged. White's dark squared bishop might look strong, but B l ack's f6-knight is also useful. So White correctly decided to exchange on f6. 16...gxf6 17.Eldl Elb8 18.Etd3 Etb4?1 This plays into White's hands, as his knight wants to go to c4 anyway.

Here Philidor's famous aphorism: "The pawns are the soul of chess" comes into play. If the pawn structure has holes or is broken, this has significant implica tions on the play. The pawns themselves can be weak, as well as the squares that cannot be defended by the pawns. These two concepts are surprisingly similar, and the section "Outpost" has already emphasized that knights usually prefer positions with many weak pawns that provide squares to settle on. So weak pawns and weak squares go hand i n hand. Important rules are: I ) A weakness that cannot be ex ploited is no weakness. This can hap pen when a weakness is a static fea ture of the position, and if one side has a strong long-term initiative, it may be impossible for the opponent to take advantage of the weakness, because h i s forces m u st defe n d against the enemy activity. 2) Most of the time one weakness does not exist in isolation, but is con-
nected with a whole weak color com plex - see "Weak Color Complex." 3) U su a l l y one weakness is not enough to win. Here the principle of two weaknesses comes into play, see "A Second Front." The fol lowing game shows how even one static weakness can affect the play: Handke,F/orian (2384) Miiller,Karsten (2503) G ER-ch Altenkirchen (9), 08. 1 2 .200 I [C09]

The ChessCafe Puzzle Book 2 Weak Color Complex
This chapter is strongly related to the chapters on "Weaknesses" and "Domi nation." As I said, usually one weak ness does not exist in isolation, but is connected with a whole weak color complex:
pieces are on light squares. 23 ... §.c7 24 . §. x a4 �c5 2 5 . §.c4 � x c4 2 6 . 4) b6+
Pavlovic,Milo.'i (2548) Jan.'isen,Ruud (2489) Corus-C Wij k aan Zee (8), 1 9. 0 1 .2004
The next two examples deal with the creation of a weak color complex: Kochyev,Alexander (2430) Shaposhnikov,Evgeny (241 5) St. Petersburg-ch ( 1 2), 1 9.04. 1 998 [A08]

To fight against a bind, you should try and sense the danger early in order to take prophylactic measures. It is also important to exchange the proper pieces by keeping important defenders on the board - usually the bishop that defends the weak color complex:

Tests
You have two hours for each of the twenty tests. Solve them from the diagrams and write your solutions on a sheet of paper. I advise you to take one test per day and then use your average score over all twenty tests. Of course, your score (or "Positional Elo") must be taken with a very large grain of salt, as tactics play an extremely important role in chess.

A stunner. This type of exchange sacri fice has been seen before, but it is more common when the destination square for the rook is covered by two pawns ( i .e., there would be another pawn on c4 ).

Although White's bishop is not exactly dominating the board, it is better than its black coun-
terpart. These kinds of endings, with one side having a clearly worse minor piece, are not that uncommon and the s t u d e n t s h o u l d note h o w w e l l Khalifman handles it. The winning plan for White is as fol lows: The first phase is to exchange the heavy pieces - the rooks will come off. Then, making sure as many black pawns as possible remain on white squares, thereby continuing to limit the scope of the bishop, White will exc hange h i s b i shop for the b l ac k knight. Final ly, alternating the threat of winning material with an invasion of the b lack position with the king, B l ack eventually is in zugzwang. Watch how "Alexander the First" carefully imple ments this plan.

All other things being equal, in a position with �+� vs. �+A, the �+� combination will usually be bet ter, again because the knight is able as sist the queen attacking any square or complex of squares. These factors are all present in this position. Kupreichik, however, realizes that he must create add itional weaknesses in the white camp - white square weakness, along which Black 's only bi shop does not travel. Watch as these elements blend into a deadly mixture for Black. 56.h51 g>g7 doesn't h e l p : '5 7 . h xg6 fxg6 5 8 . �<.14 'l;'te8
