Editor's Note A s PEIUI tramer from lhe Soviet Cbes$ School. Au3ust Livslutz has produced a classic handbook to help the aspiring player develop his or her combinational kills. The different tacucal lhemes have been co.refully selected and arranged to buj)d and consolidate themes learnt, and will prove e~cclJem sntdy material either for home study or a aroup m a o;chool or chess club. For the scriou~ ~tudent it 1s imptrarlvc to pay careful autntion to the following introduction by lhe author, as thh holds c.he key to approach.ing the tests in a systemacic way and achieving lhe maximum J>O$Sible itnprovemetu from the coorse. When studying che diagrams, please note that ·w· (' B') be.s1ck: a diagram number indicatc-o; lhat it is White {Black) to move. while • ' indicates that the player to move is aimin,g for a draw rather than a win. This book is the first of a three-volume graduated series. and cbe oompaaion 'lolumes, Test Your Chest IQ: Master ChaJ.lt"n:g.e aod Test Your Chess IQ: Grandmaster CbaJJenee. are al11o available from Cadosan.

Introduction ·~eombi nanon

is the s.ool o f cbess. •• Altunder Aktbi:ne

beginning a systematjc study of chess is invariably faced by the quescion: with what should I start? One of the greatest of chess teachers, the Cz~.h grandmasler Richard Reti , wrote: 'First you should learn to mate oombinadons, before attemptmg to play positionally.' This principle has been confirmed throughout the history of chess ~ and we seriously advise ever}' chess player to firmly adopt it. The combinations given in this boot are the fruits of the efforl$ not only of outstanding masters~ but also of littJe-lcnown players, and even of players who are qujte unknown. It cannot be disputed ,that systematic work on the solving of the given combinatjons will rais~ your chess strength significantly, and allow you to determine for yourself the class of piayer co whlcb you belong. One of the greatest players of alJ time, the former World Champion Jose Raul Capablanca, defined the importance of an acquaintance with combinations as follows: 'The majority o( chess players are interested primarily an combinations and direct attacks on the king; &uch an interest is to be whole-heartedly encouraged, smce at develops the imagination, whjcb is so necessary for a chess player. And only later. when a player achieves considerable strength, do que&tio1lS associated with the positional as.pect of play begin ·to intere~ him. • ANYONE

Combln•tlon•l themes In o.rder to consolidate the acquisition of skin. the tests m this book have been arranged according to definite combinational themes. Most of these themes are self..explanatory ('double attack' •discovered checlc', 'utilization of open file&', etc .)~ but others may be unfamiliar (e.g. 'diversion', 'decoy', 'interference') . Attempts at solving these tes-ts will soon familiarize cbe reader with the meaning of these various themes, but for anyone who require$ prior knowledae on the subject of oombinational themes, we can recommend pp. 10-SO of Nebhtadt's CattUtroplie in tht Optning (Pergamon Pr,ess, 1'980). lt may sometimes seem that the motif or theme of the combination is not exactly tho one indicated. Don't be in a hurry to follow your fust inclination, and as~gn the combination to a different theme. h should be pointed out that one frequently comes across combinations in which various ideas are combined. These are closely reJated one to another and the theme is defined depending on the final goal. To explain this , let us take the followi ng 1

I

~"Xample :

Introduction

This position is taken hom the pme Bakulin-8romtetn, played at Kiev in 1965. It &s. Black to move. The unfortunate position of the white king (the motif ofthe combination) allows the following combination to be carried out: 1 ... BdJU The very first move pursues two aims; the vacating of the 'g' file, and the diverting of the white queen. l Q xdJ The only reply, otherwise the knight is lost. l ... Jtal + !! The king is decoyed to gl. 3 Kx al ~ + Discovered check. 4 NeJ 4 Khl is met by 4 ... Qf2. when mate is inevitable. 4 . .. Rx eJ 5 QfS + Re6+ l Again discovered check. 6 Kill Qrl! White resigned, since on 7 Qg4 there follows 7 ... QxeJ + 8 Ogl Ox gl + 9 Kxgl el = 0 mate. ·One combination, but bow many combinational themes!

Typlal mi•t•k• •nd how to •void th•m In order to relate a ptayer's success •n solving these tests to his 'cbess IQ', some sample tests wer-e se.nt to a number of players. co'•ering a wide range of abltity. The solutions submitted also revealed various errors of a generaJ nature:

1. The correct idea is found , but an incorrect order of moves employed, making the combination le effective, or even rotaRy unsound. 2. The solution found ls insufficiently incisive. If one side has a m.~shing position. you can normally expect there to be a ,crushing solution1 3. Occasionally, moves are uggested which are physically impossible! This normally oocurs due to difficulty in envisaging the position several moves ahead, a skiH which. can only come with practi~ . 4. The most common error is an underestimation of the opponent's resoutces. Try to take account of aU the opponent•s possibte defences!

Gettlnf1 the mNt out of thll book

By solving a series of position' all displaying the same theme, a player will gradually acquire a •feel' for wben sucb a combmatjon is po$SibJe. Until such a sk.iJI is acquired, it is advisable to make an evaluation of eacb position, before endeavouring to find the combination. In the sohi ng of each position . we therefore recommend that, lnstead of rushing in and examining the firs.t sacrifice which comes to mind. you should ask your5elf the followiJla questions, which should enable maximum benefit to be gained from the book:

Introduction

he

1. What is the materia] situation? (If 1 am a rook down , l will have to find something pretty drastic, such as mate or the win of the opposing queen!) 2. Are there any (permanent) strategic factors in my fa.vour? Do I control the centre. do 1 have a superiority of forces around the opponent's king, is his king exposed, does he bave any weak pawns or squares. etc. 3. Are there any (temporary) tactica• faetors that I can eKploit? ls the opponent's back rank weak, are any of his pieces undefended, are there any geometrical relationships between tbe pieces. etc. 4. Having determined the advantageous featlrtes of my po$ition, can I find a sequence of moves which will eqlloit them , using the stated theme as a guide?

TKIIJing tiNI tests All the examples in this book are given in the form or tests, io. each of which: there: are eight positions to be solved. A correct solution to a position scores 5 pomts, so m each test there are 40 points to be gained. The solver should remember that a game of·chess does not continue indefinitely, and that the solving of each test must be limited by time. In each spedflc test we indicate approximately the time which is allowed. If you confine yourself to

this time, well and good. If on the solution of the test you spend more than the indicated time, then from tbe total sum of points gained you should s.ubtract penalty points at the rate of 1 point for e~ery extraS minutes. If, on the other hand, you soh·e the test more quickly, tben for each S minutes aved add I point to your score. If you are unable to solve all the posltions 1 then subtract 5 points from your total for each unsolved example . The tests are in tended ror players ofclub strength, corresponding approximaaely to thard to fourth categories in the USSR (about l00--120 on the BCF scale, o r 1900-1550 on the ELO scale). How should you set about solving the tests on your own? Apart from. a ch~s set, you will need pen and paper to write with. Set up the first position. and wrrnOUT MOVINO THE PIECES , attempt to solve it using the procedure outlined above. On finding the solution to the first position ~ write it out in fuU . On no account should you check your an~wers .after each individual position. If you have solved aU the positions correclly. and within the allotted time, you score the indicated number of points. his not a tragedy if the number of points you score at firs& is low. You will see for yourself that, after you ha\•e tackled four or fh•e tests , the number of points you score will constantly increase Your solu.tions to a test shouJd be checked only when you have finished solving all the positions in the given test. We deLLberately repeat and draw your attention to this pt>int. The time spent checking should not be included in the time allotted to the solving of the test. Uyou experience difficulty in trying to solve a position, do not be in a burry to look up the answer. Remember that , by solving a position yourself. you have already made a step forward.

YourcheuiQ The que!$lion a.s to ho~· often you shouJd do these tests will no doubt have oocurred to you. It is desirable that you should solve one or two rests a week . The total number of

points that you can score is 2240. plu~ the bonus points for usmg less tame. As was mentioned earlier , a set of sample tesu was sem out 10 a wide range of \'olunreet1, and on the ba i of their solutions we can ugge t the following table for asseuing }'Our 'Chess 10', whlch we give in term.s of a BCf or ELO rating:

It is no tragedy if you score less than 1100 points, so don't be discouraged. Oearly, you still l\ave to work at at. You will discover your deficiencies, and it follows that you will have the opportunity to eradicate them . And lt is onJy by trying that you achieve anything .

The progre•• ch•rt At the back of the book we give a chart on which you can record your scores. To give an example of &be scoring procedwe in a particular test. suppose that in one position you fail completely to find the solut.ion-dedoct 5 points. In another position you find the correct initial move, but fail to consider the best defence-deduct 3 points. (Tbe maner of ex.actly how many points to deduct for an incomplete solution we lea\•e up to your judgement and honesty.) You solve all the other six positions correctly. but ta~e a total time o( 53 minutes, compared with the .recommended time of 45 minutes. Your bask score is therefore 40- 8;:!!32, the excess time islO minutes (to the nearest5 minutes) t which means a penalty of 2 pointst leaving a net score of 30 points. There is also a space in which to record your comments on a particular lest . (Perhaps on the degree of difficulty of the test or a particular positiont o.r- heaven forbidr- a mistake in the author's solution.) Good luck!
