SELECTIONS

In each of 12 issues I have tried to give someguidance to solvers. This time I would just like tocomment on one of my fiavourite problems. lt is a mutateby Tony Lewis with I changed mates, the set and actualmates totalling 13. On both counts it seems to go beyondpast achievements, even from the heyday of the (nowunfashionable) mutate over 50 years ago.

A task problem usually contains some unavoidablycumbersome or contrived features. A pendular structure,for example, can be employed to achieve severalchanged mates. The only feature here is the wRhS whichturns out to be a camouflage piece, completing the initialblock but having no post-key function. However, such adevice has long been accepted, especially in a complete

block problem, even where there is much less variety ofplay. Indeed, Tony's problem is hardly recognisable as atask. He even has the free setting he so often achieves(i.e. the absence of pawn plugs which are so hard toavoid in any waiting problem - try it yourself!). Thehighest art is the concealment of one's art.

ORIGINALS

The #2 under PS226 to PS23{ means 'Vvhite to playand mate in two moves against any defence.' PS232 toPS234 are also directmateq but longer.

Vvith the very formal PS227 we welcome our firstWelsh contributor. This is the first of several problemsthat he has sent me. In PS230, the team of Lewis andMcDowell continue with their search for originality withmodel mates combined with strategy in the #2.

Our longer directmates are all light positions that I

hope will give pleasure to solvers.PS235 to PS240 are helpmates in which Black,

playing first, co-operates with Vvhite so that \Mite canmate Black in the number of moves specified. In PS237as well as the two solutions there is a set play solution inwhich \/write plays first and mates Black on his secondmove. PS239 is a H#4 but without Black's initial move.

PS241 to PS243 are selfmates in which White playsfirst and forces Black to mate him. The twinning in PS241is progressivq that is, each change from (c) onwards ismade from the previous twin position, rather than fromthe diagram position.

The lmitator in PS244 is a colourless, non-checking,non-capturable, non-capturing piece that exactly imitateseach move as it is played. A move is illegal if thecorresponding lmitator move is blocked by another unit orby the board edge.

PS245 is a serieshelpmate in 10 moves, in whichBlack plays 10. consecutive moves (without White playingat all) to reach a position where White can mate in one.

The grasshopper in PS246 (abbreviation 'G') movesand captures on Queen lines by hopping over the firstman of either colour standing on one of those lines to thesquare beyond that man as long as that square is eitherempty or occupied by an enemy piece. In PS246 the bGcan go to bl or d5, and if there were white pieces onthose squares, it would capture them.

PS247 is a selfstalemate in 3 in which Vvhite playsfirst and forces Black to stalemate him. There is a trick tothis problem, and perhaps familiarity with the rules ofchess as they used to be years ago, would be useful!

PS2/18, PS249, PS250 and PS252 feature the Circecondition. When captured, a piece (not a K) is immedi-ately replaced on its square of origin (game array square)if that square is empty; in the case of R, B or S on thesquare of the same colour as that on which it wascaptured. Thus a wR captured on h8 (a black square)would be replaced on a1, provided that a1 was empty; ifal was occupied the R would be removed from the boardas in a normal capture. Pawns go to the initial square ofthe file they were captured on. A replaced R is deemednot to have moved for castling purposes.

With PS25l, Ronald Turnbull presents more 'buriedtreasure' (see PS135 in issue 7) with Gheckless chess.\Mth this condition, neither side is allowed to check the

other unless it is mate. For instance, in PS251, \Mitecannot play 1.Rxg8+ because, although it is check, it isnot mate.

Composers will note from the ratio of problemspresented that I am short of three and more movers andselftnates, but that other genres are well stocked for therest of the year!

KOOCING THE B-B-BRISTOLI

Space for another instalment from my lecture. The titlethis time is a bit of a cheat, as although the reconstructedproblem illustrates the Bristol theme, it wasn't cooked,and all that I have done is improved the construction.

Some time ago (A)came to my attention.The solution is 1.Kf4l(2.Ba3+ Rxa3 3.Rd7#) with the thematicvariation 1...fxeS+2.Ks5 (3.6 #) Bxfs3.Kh6&4.895#andthe supporting line1...8xf5 2.Kxf5 (3.ex6#) Sg3+ 3.hxg3 (4.ex6#) fxe5/Ra5,Rd74.895/R(x)d7 #. Thewhite king walks upthe diagonal from e3to h6 in order to clearthe way for the bishopto mate on 95. A clearexample of the Bristoltheme, even if the

clearance is made in three moves rather than in the morenormal one.

I set out to curethis oroblem of twofaults. Firstly, there isa short threat and, in-evitably, a longer one.Secondly, it sufferedfrom what I consideredto be a somewhatheavy construction.After considerable ef-forts I came up with(B) which I was prettyhappy with. The threatis now full length and4 fewer units havebeen used. lt solvesby 1.Ke4! (2.dxe6+Kxe6 3.8a2+ Kd7 4.e6#); 'l...exds+ 2.Kfs

TURNING AN ANDERSSEN INTO ANINDIAN

byColin Russ

The chess development of Adolf Anderssen, the greatnineteenth century German Master, was unusual. He firstbecame known as a composer, and emerged onlysubsequently as one of the finest players of his age. Heis still remembered for two games in particular: theimmoftal (v. KieseriEky, 1851) and the evergreen (v.

Dufresne, 1852).

Anderssen's bestknown composition is(A). lt appeared in hiscollection of his ownprobfems, Aufgabenf irr Schachspieler(1842), the title (=Problems for Chess-p/ayers) reflecting hisown double interests.The solution runs:1.8h5 KxhS 2.K97 h63.K6 Kh4 4.K96 #.The white king inter-feres with the bishopon the third move, pre-venting stalemate, andthen discovers mate.Thanks to this orob-

lem, the manoeuvre is termed an AndeFsen mate. lthas ofien been pointed out that, if only Anderssen hadincorporated a preliminary move by the dark-squaredbishop northwestwards across 6, with the interferenceon that square to follow, he would have anticipatedLoveday's pioneering use of the Indian mechanism justthree years later. Such a move is termed critical and thesquare which the piece in question traverses, only to finditself cut off on the other side (for good AI ill), is thecritical square. In brief, the Indian enriches the Anders-sen process.of stalemate avoidance and discoveredmate with a preliminary critical move.

ln his Beispiele zurldeengeschichte desSchachproblems(1892), Josef Breuersuggested amending(A) to anive at (B),with the key 1.Bd8(1...Kxhs 2.K97, etc.,as in (A)). Now, thecritical move is there(as key), and we havean Indian. Breuer mustsurely have realisedthat 1.8e7 also solves.His proposal, (B), is ina note to the solutionof (A), and is not dia-grammed, so it is per-haps most fairly re-garded as "just athought", to be elabo-rated.

I decided to see whether Anderssen's idea couldindeed be put to Indian use, but without Indian cooking,and came up with (C) (1.8e4 Kh2 2.K94 h3 3.Kf3 Khl

103c) cAHRUSSOriginal - aflerA Anderssen

4.K93 #). I waspleased, but also sur-prised, to leam fromDr Speckmann that nosimilar reworking of(A) seemed to exist, atleast in miniature. Hewas kind enough toregard my renderingas being afterAnders-sen. rather than a ver-sion of his (A) (theformer term concedesmore originality to thelater comooser thandoes the latter). How-ever, Dr Speckmann'sletter was accompa-

nied by his suggested (D) (play as in (C)). This eliminatesa superflous element contained in the key of (C), viz., theimmobilisation of the black pawn on e5, both in the short

term and in the matealong the diagonal.The attention paid tothat pawn would leadGerman theoreticiansto describe my key asrevealing impurity ofaim, in that it is notmotivated exclusivelvby the preparation ofthe interference on thecritical square, E. Thesame school would at-tiach cardinal value tothe try 1.BB? in (D),as it is truly thematic:it fails only because itis not critical, whereasthe same move in (G)fails also becauseBlack retains the re-

source e4! For my part, I take the latter point entirely. Onthe other question, I was rather happy to think that mysolver had the admittedly easy task of finding the rightcritical move, dealing with the black pawn (so not1.8d5?...1.8d8?). I was pleased too, that the white forcein (G) undercut Anderssen's by two pawns. \Mth suchmatters are problemists' friendly debates concerned.

A NANNING #3 SAVED!

In the May issue, I presented a #3 by Nanning thathad no solution and appealed for somebody to correct it.lwas surprised and delighted when I got a response fromtwo leading problemists very quickly indeed. lt isextremely good to know that lhe Problemist Supplementis read by such people! lt was also very interesting to seehow two experts dealt with the same problem!

First through my letterbox was Jean Morice who senttwo versions. (A) (on the next page), in which the onlychange has been the removal of the wPc2 from theoriginal position, gets round the difficulty neatly byarranging a mate on c2 after the king flight. The solutionis 1.Ba3! (2.Qc2+ Kds 3.d # or 2.Sxe6+ KdS 3.Sxc7,Sf4#) 1...Re5+ 2.Sb5+ Qc4/Kds 3.Qxc4/Sxc7 #: 1...Qhs+2.Sf5+ Kds 3.Sxe3 #; 1...Sxc6+ 2.Qxc6+ Kes 3.SR #;1...Kd5 2.4+ Ke4 3.Qc2 #. The only bad point is thedouble threat, and this led Jean to have another go.

This setting makesme wonder whetherthe composer origi-nally had a wP at c2?Did he then notice thedouble threat and getrid of the pawn with-out noticing the refuta-tion 1...Kds?

Wth (B), at the ex-oense of a less eco-nomical sefting, Jeangets rid of the doublethreat. The solution isas before except thatonly the 2.Sxe6+threat works and thesubsidiary lines areslightly different:-1...Sxc6+ 2.Qxc6+Kes 3.f4 #; 1...KdS2.cA+ Ke4 3.Re3 #.

No sooner had I

studied Jean's effortswhen Bengt lngre's(C) arrived. Here, bygetting rid of the'1 ...Sxc6+ variation,Bengt has provided forthe flight and improvedthe economy of theoriginal. The threatand the thematic vari-ations are as givenbefore, but this timethe flight gives rise to'1...Kds 2.Qb5+ Ke43.Qf5 #.

It is good to see an old problem corrected, especiallyone this good. Many thanks to both Jean and Bengt. Ofcourse, these things must always be a matter of taste,but I prefer (C).

As I wrote above, response to this article has beenencouraging. Perhaps, when space permits in futureissues, I may present more old, unsound problems forcorrection.

Solvers and synthesisers should be advised. I shan'tbe caught nanning again! Well, not for a while anyway...

A STUDY AND A SERENADE

\Nhile at the Bratislava PCCC last year, I bought acopy of Eesf Sfudies by David Gurgenidze, a book that I

can heartily recommend to any study enthusiast who isnot familiar with that compose/s work, and even to thosewho are! In it there is one study that brought back a floodof memories as soon as I set eyes upon it. lt took meback to a day in 1978.

ln those days I was in the habit, as I am now, ofaftending the quarterly Friday night meetings of JohnRoycroft's Chess Endgame Study Circle (CESC) inLondon. Then, I was living in the West Country andwould spend the weekends after the meeting withRichard Harman and his wife Olive in Stroud Green. I

look back upon these weekends as oases of tranquility ina very busy life, but the real reason for them was for meto gain familiarity with the famous Harman classifiedindex of chess endgame studies that Richard had beendeveloping for many years, and that I had agreed to takeover responsibility for as soon as was necessary.

During this time, Richard was acting as director of theRoycroft Jubilee study tourney, and we decided to usethe entries as my practice in looking for anticipations inthe index. First thing'on Saturday morning I opened anenvelope ftom Georgia, and out came a study by acomposer that I then hadn't heard of, and that was

D GURGENIDZE2nd Ptize, Roycroft Jub., 1 979

destined to beawarded 2nd Prize bythe tourney judgeJohn Roycroft. A dia-gram of it is alongside.The solution runsl.Rgl f2 (i) 2.Rf161=Q+ (ii) 3.Rxdl e24.Rf3+ Kg7 5.R93+KfG 6.Rggl with theechoed lines 6...KeS7.Rgel (iii) 1-0 and6...Kf5 7.Rdfl 1-0. (D

1...e2 2.Rxf3+ Ke73.Re3+ & 4.Rxe2 1-0;(ii) 2...e2 3.Rx2+ Kg74.R93+ & 5.Rh2 #; (iii)7 .Kb2? exd 1 =Q8.Rxd1 Ke4 9.Kc2 Ke3= or 7.Rdf1? (say)fxgl=Q 8.Rxgl Kf4 =.

This simple but elegant echo had me asking Richard fordetails of other work by the same composer. The judge'senthusiastic comment on it was 'A miniature whosecharm grows, and grows!' and, sixteen years later, I stillagree with him.

Being introduced to the work of David Gurgenidzemight be considered enough luck for one day, but morewas to follow! Evenings at Stroud Green were spent inlistening to records, and this particular evening Richardasked me if there was anything that I wanted to listen to.As I had recently discovered the work of the Englishcomposer Ralph Vaughan-Wlliams, I suggested thatanything by him would be of interest. ln response,Richard played the Serenade To Music. This was my firsthearing of that work, and I sat entranced from the time itstarted till the time it ended. At that time I thought that itwas the most beautiful piece of music that I had everheard, and, sixteen years later, I still think so.
