NAMES AND NUMBERS

The question how many composersare represented in EG's pages iseasily asked but less easily answered.For example, are Komai and Comaytwo composers or one? Someaccount of EG's spelling of names,possible because one person has beenresponsible for a quarter of a century(a situation which may never recur)may therefore be useful. The princi-ple we consciously tried to follow isto repeat the native spelling wherepossible, and otherwise to approxi-mate in educated English to the pro-nunciation while bearing in mindboth traditional spellings and thepresence of a majority of non-English readers of EG. We have lear-ned 'on the job' and have tried to beconsistent. Of course we failed. Alp-habets, syllable stress patterns(including their absence), pseudo-similarities, strange diacritics, andlinguistic ignorance have all contri-buted to our failure. A challengewhich thankfully I never encounte-red was the spelling of the name of aChinese composer, because up tonow there have been none. My suc-cessors will, I hope, have to sort thatout!

Comay (preferred) = Komai,KomayCosteff (preferred) = KosteffGalushko = Goloshko, etc. (Volgo-grad composer)Garayazli supersedes earlier varia-tions

Janosi (now preferred) = IanosiJoitsa = JoitaKondratev (preferred) = Kondra-tiev, KondratyevOlympiev = OlimpievKozirev = KozyrevPogosyants (preferred) = Pogos-jantsSenkus is correct (Syankus, Sekusoccur in other sources)

MISCELLANY

Genrikh Kasparyan is the father ofSergei Kasparyan. Likewise there arefather and son Manyakhin. Theseveral Kuznetsov's and Ivanov/Iwanow's must be kept apart. Thereis a second contemporary Polishcomposer named Andrzej Lewan-dowski in addition to the well knownmaster from Torun. Gul(y)a(y)evand Grin are one and the same. Afekwas Kopelovich. Carvajal Aliaga(EG36.2040) is the Carvajal ofEG89.6586, while for similar Hispa-nic reasons Javier Rodriguez isJ.R.Ibran. Benko and Benko areinterchangeable, but Benno is not.Belyavsky and Gurgenidze the sovietcomposers are not the soviet otbIGMs. There are (or have been) seve-ral Kovalenko's, two Vlasenko's andNovikov's, while the New ZealanderEmil Melnichenko must not be con-fused with soviet namesakes. Gher-man Umnov is not the late EvgenyUmnov, while EG89.6580 is by athird Umnov.Quite apart from the foregoing are

937

typos, that is, typographical orproof-correcting errors. On balancethe spelling in a solution is morereliable than that above a diagram.For example 'Blinka' (EG96.7279),'Plinka' (EG94 p452) and 'Mlinka'(EG92.6822) are all to be interpretedas Hlinka. These may be 'obvious'corrections, at least to regular rea-ders, but human history and com-mon experience attest that theobvious is often wrong.

Magazines may also confuse. FromSlovakia come PAT A MAT (Brati-slava) and MAT-PAT (Martin), bothof them composition magazines. Itdoes not help that the former's dis-tinguishing motif comprises a 5-let-ter monogram, namely a verticalMAT crossing a horizontal PAT. Ifpossible, one looks to see how amagazine refers to itself.

TWO RUSSIAN ENIGMASWhy did the Russians apparentlynever use their own alphabet todenote the chessboard files? Theirvery first chess books (by Ivan Butri-mov in 1821 and Alexander Petrov in1824) adopted the western a-h sys-tem. This is surely all the odder,given that the Russian alphabet hasno letter 'h' - whence Gitler, Gerb-stman, Giskot for Hitler, Herbstmanand Heathcote. Subsequently theusage was adopted by the first chessmagazine Shakhmatny listok (editedby Viktor Mikhailov from 1859 to1863, and by Mikhail Chigori n from1876 to 1891) and it has never wave-red. The chess historian Dr IsaacLinder of Moscow (in a letter of16iv90) has kindly traced the fore-going basic facts. So we know someof the who, what, where and when.We still want to know why! There iseven the question of the extent towhich the Russian alphabet was ever

used in print or in the hand recordingof positions and game scores. Thepractice is a great convenience forwesterners, but western ease of use isnot likely to have been the reason forits adoption! One reasonable possi-bility is that the impetus was techno-logical rather than caissic, a conse-quence, maybe, of the import ofready-made chess diagram printingtechniques from, say, Germany - onethinks of the very old tradition ofletters along the bottom and top ofthe board and numbers down thesides.Russian took over 'mittelspieF fromGerman, but 'debyut' from French.Now 'etyud' is French, and again wewant to know why - as well as thebasic facts.As one starting-point there is theremarkable fact that the Russian dic-tionary Dal' of the year 1902 includesthe chess meaning of'etyud', while even the largest wes-tern dictionaries we have consultedstill do not today. Dr Linder helpswith facts relating to the first Rus-sians who can be called study com-posers: A.Petrov, Karl A.Jaenischand Ilya Shuwmov. Decouvertes sur lecavalier (Jaenisch) appeared inFrench in St Petersburg in 1837, andthe same author published studies inhis chess column in Sankt Peter-burgskie vedemosti in 1856. Shumovcomposed studies in the 1860's, someof them published in La Strategie inFrance. It has yet to be shown, howe-ver, that the word etyud was appliedunambiguously in any of these ins-tances.Preliminary research has taken usjust this far. Clearly here is just thesubject for a thesis by some diligentresearcher with linguistic skills andthe funds to commute between theDutch Royal Library in the Hagueand the two major libraries of theUSSR (the Lenin Library in Moscowand the Saltykov-Schedrin Libraryin St. Petersburg). We are serious.

EG 102.1 The GBR class 0116 end-game' (pp865-866)

1. The essential indication (of a com-puter source) *C* was omitted.2. Lewis B.Stiller, a 25-year-old gra-duate of Johns Hopkins University,Baltimore, was greatly assisted byNoam Elkies of the Department ofMathematics, Harvard University.Our apologies to both gentlemen forthis omission. The CM-2 Connec-tion Machine was located at LosAlamos and used remotely. Stillerand Elkies have not yet actually metface-to-face! [Thinking MachinesCorporation have recently announ-ced a CM-5!!]3. A short article in the November1991 SCIENTIFIC AMERICAN hasled to spin-off newspaper publicityincluding a front-page item in theLonden TIMES (30x91) headed 'Atlast - white to win in 100 billionmoves'.

EG102.1p859 The Troitzky 3rd Prize diagram(d6/gl) should have wPe5 (notwPe6), and the applicable solutionsays 'second', despite being printedas third on the page.p874 col.l read: The book is inEnglish so the content is more acces-sible than the Russian ' A-Z' reviewedabove, though whether the volume ismore accessible is an interestingquestion: the Russian edition sizecontrasts with the few hundred of theDutch.p935 col.2 (top) read: EG97.9394 ....W also wins if dark wB can be exc-hanged with check, allowing g2-g3,when wK marches to h6 to win easily.

SNIPPETS1. A posthumous paper by Selmanon reciprocal stalemate has been edi-ted by Jan van Reek and published(in English) in the ARVES series.2. A long and wonderful collectionof Jan Marwitz' studies has appea-red in the ARVES series. They aredeeply commented and annotated bythe composer himself. In Dutch.3. Jan van Reek's comprehensiveHistory of Study Composition in theNetherlands has been completed,sponsors have been found, andpublication is imminent. This is inEnglish.

4. The composer of EG 97.7391 is asenior Argentinian otb master.5. *C* Ken Thompson's BELLE (acomplex amalgam of computerhardware and software) succesfullysolved 9 out of 10 studies in the EG 63article (1981).6. For the record. Volume I of EG(EG 1-16) consisted of 524 pages.Volume VI (EG 83-102) has nearly athousand.7. A consolidated index to EG 1-102is not ruled out, but it is not a com-mitment, least of all by AJR.8. For the record, Volume I of EG (ie,EG1-16) consisted of 524 pages.Volume VI (EG83-102.2) has nearly athousand.9. A book 'A to Z of Studies' iscontracted for publication. As thepublisher is Maxwell Macmillan, wemust keep our fingers crossed.Author/compiler: AJR.10. EG 103 and EG 104 should bewith subscribers before EG 102.2.Most awards were prepared by AJR,diagrams prepared by Bas de Heer,and everything else done by Stakha-novite (if one may still use the wordas a comp. lent) stand-in editor Janvan Reek. Full steam ahead!11. Theo van Spijk. EG's printersince EG 3, had af four-fold heartbypass operation in Aug. '91, aftertwo heart attacks while on holidaywith his family in Spain. Aged 58,Theo is recovering well. Our sym-pathy and support reach out to him,to his wife Diny and his son Pascal.12. *C* All of Henri Rinck's claimsto have discovered new draws(not based on the Lolli position) inthe GBR class 1060 are erroneous.(See '1414' passim.)13. Judged by Gh.Umnov, the 10thindividual championship of 'Russia'(ie, the Russian Federation, orRSFSR) was won by A.Maksimovs-kikh with 38 points ahead of V.Kozi-rev, also 38. Next in order: Kopnin,Anufriev, Gromov, Rumyantsev,

Makletsov, Arestov, Osintsev, Rya-binin, Malyshev, Migunov, Seliva-nov and Sidorov. These placings inthe last-ever such soviet champion-ship are 'final'.14. Shakhmatny Bulletin is nowreplaced by Ekspress-Shakhmaty;Ceskoslovensky Sach has breathedits last, no doubt to be replaced.15. Computer specialist AlekseySochniev is now working in SouthAfrica, probably temporarily.16. The British Chess FederationYear Book 1991-92 (in general a uni-que mine of facts about the contem-porary British chess scene) reportson the 1990 Benidorm PCCC andWCSC meeting, but re-locates thewhole event to Basildon (a smalltown in the county of Essex)!!! In1992 Britain is supposed to knowabout Europe!

XXXIV PCCC Meeting (WCSC,etc.) Rotterdam 3-10.8 '91.- studies-related report -1. New holder of title of FIDE judge:Vladimir Kos (Czechoslovakia).2. A new applicant for the title ofFIDE judge must now submit sixawards, two made outside his home-land.3. Studies Sub-Committee3.1 Study EG92.6858 was chosen (by the abovesub-committee using a system of

940

votes) as 'study of the year' for 1986,just as one of its composers, Maksi-movskikh (the other was Dolgov),won the soviet championship - as ithappens, the very last one! At thePCCC banquet the soviet solvingteam expressed shock at this award,alleging the study to be known to beunsound. [Comment: not only hadnobody told us , but the Georgiansclearly were unaware likewise. Typi-cal poor communication, which wemust work in this new world of theCommonwealth of IndependentStates to improve!] The study (1st Pr,Troitzky '120' MT) is not included inthe recent book selecting Maksi-movskikh's best studies.

Among the mini-lectures deliveredto an ARVES get-together held in acaf some distance from the InntelHotel (PCCC venue), and attendedby nearly 50 enthusiasts, IGM John

Nunn demonstrated how he hasextracted studies from 5-man data-bases (using a ChessBase interface).The very interesting questions are:who/what has composed them, howought they to be described, and howshould judges treat them if enteredfor a tourney (this is happening!)?5. The Match: USSR vs. Rot W stillhangs fire. The Moscow and Tbilisijudges have so far failed to submittheir ranking lists while the Londonjudges (Nunn and Roycroft) did so inJune 1991.6. WCSC. After the studies solvinground was complete it was foundthat all three studies were defective.The round was then cancelled andthe championship (convincingly wonby the USSR) decided on problem-solving alone.7. The FIDE Album 1983-85 shouldbe out 'any day now'. Just like EG.8. No one from ARVES was presentat Rotterdam to accept EG subscrip-tions for 1992, etc. We trust that thispublic relations disaster will not berepeated at any future PCCC mee-ting.9. The XXXV PCCC meeting will beheld in Bonn (Germany)22-29VIII92.

The accepted 'conversionmetric' algorithm allocates no prio-rity between a checkmating moveand a winning capture move wheneach is equi-optimal. If there is aforced mate in 3 but a forced win-ning capture in 2, the latter is prefer-red unless the alternative 'metric',the 'checkmate metric', is followed.Computers handle either metric,while human specialists prefer theconversion metric until they sensemate. In (won) endings against thelone king there is by definition no'conversion'. It surprises many peo-ple when they realise the logical con-sequence that chessplayers and com-puter programmers will never agreeon a generally applicable definitionof 'best move'.

Roland LECOMTE's article received31VIII 91The following article (here transla-ted, condensed and edited by AJR)was prepared by the well knownjournalist Monsieur RolandLecomte expressly in connectionwith the Lyon World Championshipstage held in Lyon in 1990. It has notpreviously been published.

HENRI RINCK(1870-1952)

Chemical engineer, prodigious chessartist, record holder, and distinguis-hed son of Lyon

The supreme and inimitable work ofHenri Rinck, born 120 years ago inLyon, occupies an immense space inthe world of chess: no less than half acentury of research into opposingchess force scarcely studied previou-sly, of composition, of verificationwith meticulous care, ever faithful tohis motto 'with willpower, patienceand perseverance'. His 190 tourneyhonours include 60 first prizes car-ried off in 102 international competi-tions. Nicknamed 'the Victor Hugoof chess' for the fecundity and qua-lity of his artistic endgame studies,his life and work are hardly separa-ble.

The man. Henri Rinck was born inLyon 10il871 at the erstwhile Rinckbreweries located at the Cours duMidi (later Cours Verdun) of Frenchparents and a grandfather fromAlsace. Educated first as a pupil atthe Lyon lyce, and then at the Techni-sche Hochschule ('cole Polytechni-que') of Munich in Bavaria where heleft with a diploma in chemistry, heentered the Lyon Faculty of Sciencewhere he spent two years as assistantto Professor Philippe Barbier in thechemistry laboratory. Thereafter hecontributed much to the prestige andimage of the tablissements Rinck inthe heart and capital of the departe-mentoi Rohne.

In 1897 in the course of specialistwork on chlorophyll Rinck inventeda process for the purification ofgreen vegetable oil. He introducedthe process first into several plants inMarseille, and subsequently into alarge number of refineries for grig-non

945

and olive oil in Barcelona (Spain),where he moved in 1900, and wherehe stayed for the rest of his life.

Rinck's physiognomy expressedcalm energy and goodwill. His gazewas both frank and distant, that of aman of action who is at the sametime thinker and sensitive poet.From this presence (in both literaland figurative senses) a feeling emer-ged which compelled sympathy andrespect. He died at Badalona (Spain)on 1811 1952, aged 82, after a shortbut painful illness.

The passion. From the age of 16Rinck experienced an irresistible lea-ning towards chess, an inclinationand a passion which he was fortu-nate to be able to combine with hisprofessional career.

Already champion of the town ofLyon he played, and won prizes, incorrespondence tourneys organisedby the monthly chess magazine 'LaStratgie'. He also won a two-gamematch against the Algiers chess club,the players of the latter combining inconsultation. At 20 his analyses ofthe Muzio and Kieseritzky Gambits,and the French Defence, were publis-hed in 'La Stratgie'. Games played atthis time show Rinck's mastery.

Only later, in Spain, through contactwith his 'brother in arms' Jos Tolosay Carrera and with the great problemcomposer Valentin Marin (theybecame inseparable friends) didRinck enter the realm of chess com-position - with two-move problems.

The records. Rinck carried 190major honours in 102 competitions.Rinck was always a striver, nevercontent. He swept the board at Malm(Sweden) 1924 with the first threeprizes and first three honourablementions. And he did exactly the

same the following year, despite allopposition. At Florence in 1925Rinck took six prizes in another tour-ney. Enough to put the fear of Godinto other competitors!

The artist. Rinck's first studies datefrom 1902. In 1907 his '150 Fins dePartie' was published (there werethree editions). In 1919 '300 Fins dePartie', and in 1927 '700 Fins de Par-tie'.

In the space of 20 years Rinck hadscaled the peaks of his chosen art.His style was unmatched, characteri-sed above all by its form, which dis-plays absolute beauty and purity. Bythis time his name is celebrated in allthe countries of the world. 'Les sur-prises de la thorie' appeared in 1947in Madrid (in French and Spanish),bringing together 111 endings (and afurther dozen) dedicated to his nep-hew Jacques Rinck, printed in redand black.

The ultimate demanding task, one atwhich he laboured to his last breath,resulted in final victory (among somany others) over death, when hehad the joy, six days before his depar-ture from this world, to hold in hishands the first copy of '1414 Fins dePartie'. In accordance with hiswishes the volume accompanied himto his grave. The original edition,published at its author's expense,was made in an edition of 500 copieson 10U952 by the 'Tipografia LaAcadmica' at Barcelona for the aut-hor's 82nd birthday. It is a master-piece, from the standpoint of bothform and content. The type was enti-rely set by hand, the labour of aBenedictine monk, simply not possi-ble today due to the exorbitant cost.Monsieur J.Guisle, the former spe-cialist bookseller of 13 rue Saint-Jacques (Paris 5e) took charge ofhalf this edition, which was sold out

946

on the spot. The volume is 15cm x27cm, has 760 pages, 238 of themwith diagrams six to a page (at leastone masterpiece per page), and 530for the solutions. The work 'of awhole lifetime is dedicated to thehouse of Rinck and, in the firstplace, to its primary representative,Monsieur Jacques Rinck of Lyon'.1414 Fins de Partie (together with anappendix of a further 26) are asmany pearls of which each, polishedto the last degree, has the purity andsprakle of a diamond.An imperishable jewel - and magic,because what strikes us when we exa-mine a study by the Lyonnais masteris the improbability of the outcome.

The verdict of his contemporaries.Osip S.Bernstein (an internationalgrandmaster of practical play): 'theartistic study shows that the value ofa position, viewed under the lamp ofgenius, differs from its apparentvalue. No one has systematised stu-dies as Henri Rinck has. What anenormous task it is to systematise

exceptions to rules, some of whichare by their nature intangible! Spirittriumphs over matter, will over fate.'Vitaly Halberstadt (artist, masterand eclectic connoisseur of studycomposition): 'A unique model inthe history of the artistic endgame,Henri Rinck possessed in the highestdegree qualities which it is rare tomeet in one man: genial constructor,penetrating visual acuity, great tena-city, and a remarkable capacity forhard work. His clear methodicalmind gave him the tranquil assu-rance that he had worked well. Rus-sian folk-lore has it that the universeis borne on the backs of three greatwhales. We might say that the trio ofwhales supporting our little universeof the endgame are in chronologicalorder the Germans Kling & Horwitz,the Russian Troitzky, and theFrenchman Henri Rinck'.

REVIEWS

REVIEW 'The Comprehension ofBeauty', by A.K. Kalinin, 160 pages,Moscow 1990, in Russian. Chess com-positions by the armed forces, and abook on it, would be unthinkable inany other country, let alone in an editi-on of 50.000. The study composers in-clude Kalinin himself (represented by33 studies and very unlucky in EG'sBent JT), Bondarenko (61, ma-ny jointly composed studies), Evreinov(30), (Kanonik, a problemist, but con-ductor of the newspaper ChervonyGirnik's tourneys for 30 years), (Fokin, also a problemist but also an influen-tial columnist, this time of Vecherny

Leningrad) Ulanov (5), Razumenko(19), Tolstoy (6), Asaba (32), NikolayFilippovich Vlasenko (2), Mazur (8).The figures are numbers, not ages!

REVIEW el arte del ESTUDIO de aje-drez, by Zoilo R. Caputto, Vol. 1, Bu-enos Aires, 1990. In Spanish, 318 pa-ges, with many diagrams and copiousillustrations. The is no price. The copyunder review is one of an edition of 50,numbered and signed. We trust that alarger edition will follow for wideravailability. For a private publicationthis work is of exceptionally high qua-lity, due to intensive and extensive re-

947

search over at least five years by Pro-fessor Caputto who has correspondedfar and wide. Academic thoroughnessis repeatedly in evidence, especially inthe footnotes. There are names andsources which are to be found neitherin Bondarenko's Stanovleniye nor inRoycroft's The Chess Endgame Study.Starting with the origins of chess itselfwe are taken in this first volumethrough the mansuba period, themiddle ages, the Spanish and Portugu-ese contribution, the Italian, then thegreat Italian School, the French andEnglish influence, with 1851 as theKling & Horwitz watershed. The selectionsfrom Stamma (18), del Rio (21), Pon-ziani (9 del Rio's), and Lolli (9) are ad-mirable. The numerous drawings andreproductions bringing together themajor nineteenth century personalitiesenable us to observe that the portraitsmight have be made expressly to inti-midate children! A knowledge of Spa-nish (which we do not have) is needed tofollow the text, but there is much plea-sure and gain even without. An appen-dix displays analyses and studies by aselection of 'the modern champions'.A fascinating inclusion here is a pieceof the score, not of a game, but of asoprano duet, from the opera Tom Jo-

nes by Philidor. The author finally gi-ves a tantalising foretaste of the con-tent of Vols 2 and 3, which will respec-tively cover modern composers andcomposing itself.

REVIEW 'The output of a genius', byV. Kirillov, Riga, 1990, in Russian.The introductory matter, including theP-ending win against Capablanca in asimul in Riga in 1913, is the only signi-ficant addition to what has alreadybeen published in Whitworth's book.The subject is German Mattison. True,Whitworth will envy the edition size of20,000. There are 53 studies, 5 supple-mentary positions, a game, 9 pro-blems, an article by Koblents and Mat-tion's tournament record.

REVIEW 'The Truth-seekers', 128 pa-ges, Kurgan 1991, in Russian, soft co-ver. Half of this book covers IGM Yu.Balashov's career, while the other halfdeals with A. Maksimovskikh. Bothare local heroes and each seems to ha-ve authored his part of the book - asi-de from the inevitable introductions byotb IGMs! The 64 Maksimovskikh stu-dies range from 1963 to 1987, of whichsome 15 won high prizes. There arealso a few problems and photos.

GBR class 0312

1.1 0312 occurred in Karpov vs. Kas-parov at Interpolis, x91, with Karpovhaving the upper hand. The gamewas drawn under the 50-move rule,but Karpov found an effective wayto drive Kasparov's king to the edge -and came close to winning. Kaspa-rov's defensive strategy of keepinghis rook out of harm's way andretreating his king towards the cor-ner not controlled by the bishop is

certainly correct, though his play hasa passive flavour. In fact, we learnfrom Stiller/Elkies, at no point in theplay did Karpov have a win.

1.2 There are 52 studies starting withthis material in Rinck's '1414'. Nosolution exceeds 7 moves in length.Mostly they are domination studies.All are meticulously analysed. Thefollowing two show the defendingking in the good defensive corner(which Rinck states to be a generaldraw, as opposed to the other corner,which he deems lost).

1.5 The only argument for a general

win (we know now that there is nogeneral win) would be if the defen-der's king in the good corner cannevertheless be driven out and forcedinto a bad corner - a process thatmight take 150 moves. There is a pre-cedent with the 5-man endgame twobishops against knight, where theone consensus draw turned out notto be a draw. With six men we are innew territory as regards computerinvestigations.

All due to the Stiller/Elkies duo exer-cising their powerful algorithm onThe Connection Machine in LosAlamos. We learn that all Zugwangsand WTM/BTM statistics have beenextracted, but details are still lac-king. What interesting times we livein and lie ahead!

Except that it makes noattempt to win any drawn position itperforms beautifully. The depths of

all moves (1-ply) from the displayedposition can be displayed or concea-led.1.2 Further data bases are promisedfrom ChessBase, but there are severedifficulties preventing the compres-sion of data bases (such as 1033 10601006 0023) where draws are theexception. This is because every wonposition has to have an associateddepth. However, we look forward to0014 and 1600/3200.1.3 Ken Thompson has privatelyindicated his interest in generating6-man pawnless databases 'to con-version' (good!), since he has accessto new hardware.AJR has proposed 0321 and 0332,but Ken always makes up his ownmind.1.4 Any 6-man data base needs to bedistributed using CD-ROM techno-logy. To attach CD-ROM to a PCcosts about £ 500 - at present.In 91 Ken Thompson distributedtwenty-two 5-man endgame databasesto friends, using CD-ROM and a Huff-man coding compression technique.The CD-ROM itself weighs just half anounce!

6. The 10 study positions of the com-puter micro test reported in EG63(ii81) were also solved, later, and withgreat success, by Ken Thompson'sBELLE - only one move gave trou-ble!7. The sixth conference in the seriesAdvances in Computer Chess tookplace in London in viii90. The papersare now published. They include Tomake dumb skill endgame data basesspeak', jointly authored by Don Bealand AJR.8. Lewis Stiller (see EG98) discardedhis 5-man data bases. And why?Well, why retain what can be regene-rated within a minute or two?! Whata world we live in, when all that weneed is for everyone to have access tothe Connection Machine and to bean ace programmer! In addition topawnless endings Stiller also genera-ted many data bases with a pawn.Bare statistics are in the ICCA Jour-nal.

My personal opi-nion is that composition prizesshould not be awarded for difficultyof solution, but there is no doubtthat if such a prize were to be awar-ded it would go to No.8196. ... Theingenious introduction is a solutionon its own, but artistically it is notrelated to the quite incredible mainline contortions.

Judges have long recognisedthis fact, and have developed the cus-tom of awarding 'Special' prizes,'Special' honourable mentions, and'Special' commendations - and evenplacing together special sectionsaltogether, for instance of 'minia-tures' (maximum of 7 men on theboard), although the tourneyannouncement may have made nomention of such separation.

A differentway to resolve this ethical dilemma isfor a second judge to be responsiblefor judging a judge's entry. An alter-native alternative is for the study notto compete in any tourney. To mymind the 'second judge' solution isthe best as being fairest to all concer-ned - and the tidiest, for it causes-least confusion in the long run, sinceonly one question has to be answe-red, namely: how did a judge judgehis own entry?
