This is a unique training program that aims to help intermediate and advanced players by offering a large number of examples carefullysele cted 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!

4 Introduction
Why is it so much easier to find books that fo cus on tactical exercises rather than positional tests? One reason is that it is easier to locate suitable examples of tactical combinations - at least fo r 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 difficultto 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 introductorychapters of motifs, but you can, of course, start with the exercises as a warm up. If 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 fa r you must calculate to get fu ll scores. Sometimes it is sufficientto findthe first move, at other times you must calculate several moves ahead to ensure that your idea really works. Themes like "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 memoryand to recognize the patternsmore 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 fo r adding many explanations, Susan Polgar fo r her fo reword, Mark C. Donlan, Helene Romakin, Nikolas Lubbe and Steve Goldberg. Special thanks to Jacob Aagaard for testing the exercises.
I wish you plenty of fu n with the puzzles and I hope that your overall perfor mance improves!

5 Motifs
Good and Bad Bishops
The bishop can only move on half the Ho/lis,Adrian Swayne (2606) - squares of the chessboard and this has Hovde,Frank (2534) many positional implications. If one Corr. 1991 (8) 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).
A) Bad Bishop

In our firstexample, White's dark-squared bishop is permanently bad, as the doubled c-pawns and the blocked f4 - pawn fo rm 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.

David,Aiberto (2487) - Plaskett,Jim (2525) B) Attack with Opposite-Colored Mondariz zt 1.1 (I0), 13.09.2000 Bishops Pure opposite-colored bishop endgames have a very drawish nature (see Dvoretskys Endgame Manual or 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 Seidler - Ruiz with the attacking rooks, decides the Buenos Aires, 1974 issue: 26.4)d5! 26.§g3? 28 • .§7e6! Black cannot defend the dark squares around his king. White wants to keep as much attacking poten tial on the board as possible, so he does not exchange pieces. 28..• d5 28 ...�g7 Black's king is fe eling the danger, but 29.§xd6 �g6 30.§eS MS 31.§aS+- . 7 The ChessCafe Puzzle Book 2 29.Jl.xf6 d4 30.§g3+ �h7 30 .. .'it'f8 Black's initiative is very strong, as 3l.Ae5! +- . 31.§g5!? d3 3l...E!.d7 White cannot block the long diagonal: 32.E!.xh5+ 'it>g6 33.g4 'it>f7 34.f5 E!.a a7 30.�g1?! 30.E!.c5 �e7 3l.b4 �e4 35.Axd4 +- Ftacnik in CBM 79. 32.�fl was more tenacious. 30 ... �d5 32.§xh5+ �g6 33.§g5+ �h7 31.§xd4 �f3 32.J}.e1 .§e833.§d2 34.Jl.c3Jl.d1 35 . .§e3 1-0 h5!

Jonathan Rowson describes this in The Seven Deadly Chess Sins (page 130) as fo llows: "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 the other can't in principle ...There may be something 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 24... §x e4! 25 . .§xe4 d5 26.§xd4 than the sum of their parts.

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: 8 Motifs Naiditsch,Arkadij (2524) - 32.cxb5 tzlxe4 33.§.xc8 �xc8 34.�xf4 Lutz,Christopher (2643) Ag5 35.�fl tzld2 36.�f2 tzlc4 37.�c2 GER-ch Altenkirchen (9), 08. 1 2.200 1 axb5 �. 3l ...b)(c4 32.�)(f6+ ...Q.)(f6 33.thd6 �d3 34.�)(b8 Et)(b8 35.Jl)(d335.§. xc4tzlb2 -+ is the tac tical justification. 35 ...c)(d3 Black is winning because of the bishop-pair, combined with the light-squared weak nesses in White's camp, and the passed pawn on d3 . 36.Etc4 Etbc8 37.Jl.c5 Jlc6 38.�b3 ...Q. b5 39.Etc3 Jlg5 40.a4 In this typical Hedgehog structure, Black successfully undermines White's overextended center and ultimately wins the bishop-pair.
