Aron Nimzowitsch


‘The most remarkable winning move on record’ was Reuben Fine’s description of 25...h6 in the ‘Immortal Zugzwang Game’ (page 130 of his 1951 book The World’s Great Chess Games). On page 32 of Fifty Great Games of Modern Chess, Harry Golombek called it the ‘finest possible example of Zugzwang’. Fred Reinfeld considered it Nimzowitsch’s ‘most famous game’ (Great Moments in Chess, page 107). As will be seen below, all that may or may not be true, but initially the game was virtually ignored by the chess world.

First, for ease of reference, the moves:

Friedrich Sämisch

It is tempting to imagine the game being instantly flashed around the planet as a unique specimen of hypermodern technique resulting in a hapless opponent being tied up, or down, hand-and-foot. In truth, the score is absent from almost all the major chess magazines of 1923 (e.g. Deutsche Schachzeitung, Wiener Schachzeitung, BCM, American Chess Bulletin and Tijdschrift van den Nederlandschen Schaakbond).

Nor did it appear in the 25-page ‘Games of 1923’ section in Chess of To-day by Alfred Emery (London, 1924) or, even, in Ludwig Bachmann’s Schachjahrbuch 1923 (published in Ansbach the following year), which had nearly 180 games. The year Nimzowitsch died, 1935, Reinfeld brought out a monograph entitled Thirty-five Nimzowitsch Games, 1904-1927, but there was still no ‘Immortal Zugzwang Game’. Some subsequent ‘standard sources’ also ignored it, an example being 500 Master Games of Chess by Tartakower and du Mont (London, 1952).

zugwzang

It was, at least, included in the Copenhagen, 1923 tournament book (page 23), albeit with a mere seven brief notes in Richard Teichmann’s characteristically desiccated style. Black’s 15th and 16th moves were allotted one exclamation mark apiece, but Teichmann showed little enthusiasm for the finale. The tournament book also came out as a supplement to the periodical Kagans Neueste Schachnachrichten, between the April 1923 and June 1923 issues, and Teichmann’s comments were used on page 106 of the July 1923 Časopis Československých Šachistů. It was hardly an auspicious start for the ‘most famous game’.

Eventually, Nimzowitsch went on a propaganda blitz. He burst into annotational song on pages 17-18 of the 2/1925 Wiener Schachzeitung under the heading ‘Zugzwang on a full board!’ Double exclamation marks accompanied Black’s 10th, 20th and 25th moves, and the high-spirited victor described 25...h6 as follows:

‘An exceptionally beautiful problem move! This puts White in nothing less than a tragic Zugzwang position (I won’t say tragicomic, since the sheer force of Black’s play rules out any thought of humour).

... In the opinion of the well-known Danish amateur master, the writer/editor Hemmer Hansen, this game would be worthy of being placed alongside the “Immortal Game”. While Anderssen was able to deploy the “sacrifice” as such to maximum benefit, I, Hansen said, achieved a similar effect with the Zugzwang. In Danish chess circles, this game is therefore described as the Immortal Zugzwang Game!’

Later that year, he continued in the same vein in his first book, Die Blockade (page 52), writing of 25...h6:

‘A brilliant move which announces the Zugzwang. ... This unusually brilliant Zugzwang mechanism makes this game, which Dr Lasker in a Dutch publication called a magnificent achievement, a counterpart to the “Immortal Game”. There the maximum effect of the “sacrifice”, here that of the “Zugzwang”.’

The Lasker article (in a Dutch newspaper?) has yet to be located.

Die Blockade was followed, also in 1925, by the first edition of Mein System, in which (page 55) Nimzowitsch had fresh words of acclaim for his performance:

‘... a short game, which is known far and wide as the “Immortal Zugzwang Game”. It is of interest to us because the outpost is used here merely as a threat or even just as a ghost. And yet its effect is enormous.’

It had been a quick transition from commendations in Danish and Dutch sources to recognition ‘far and wide’. Meeker sentiments by Nimzowitsch appeared in the English edition, My System, published in 1929, although that version did have his closing remark, ‘a brilliant move which announces the Zugzwang’.

The English translator of My System was Philip Hereford (i.e. Arthur Hereford Wykeham George, who died in 1937). His introduction, dated 29 August 1929, referred to Zugzwang as the only word left untranslated in the book, ‘partly since it is [sic] become familiar in English chess circles, partly, in fact mainly, because the single word conveys an idea, or complex of ideas, which can only be expressed in English by a circumlocution’.

In reality, the term Zugzwang was not commonly found in English-language chess literature prior to the publication of My System. In German, though, it had been in regular use in the nineteenth century. Pages 353-358 of the September 1858 Deutsche Schachzeitung had an unsigned article ‘Zugzwang, Zugwahl und Privilegien’. F. Amelung employed the terms Zugzwang, Tempozwang and Tempozugzwang on pages 257-259 of the September 1896 issue of the same magazine. When a perceived example of Zugzwang occurred in the third game of the 1896-97 world championship match between Steinitz and Lasker, after 34...Rg8, the Deutsche Schachzeitung (December 1896, page 368) reported that ‘White has died of Zugzwang’. As is shown, inter alia, by the appearance of that game in the Fine/Reinfeld collection of Lasker’s masterpieces, published in 1935, Zugzwang established itself in English-language chess sources in the 1930s.

Then came the quest for a satisfactory translation or circumlocution. The most frequent rendering nowadays is compulsion to move, but many fanciful proposals had to be endured first. Discussing the position reached after 40...Qe2 in Bogoljubow v Alekhine, Hastings, 1922, Brian Harley offered straight-waistcoat on page 27 of his 1936 book Chess and its Stars. That, in turn, was converted into US parlance as straightjacket by the American Chess Bulletin (July-August 1936 issue, page 120). On page 266 of the 14 March 1939 CHESS, H.G. Hart suggested move-bound. The same magazine (20 August 1939, page 438) recorded R.E. Kemp’s offering of squeezed, ‘in use in his club 45 years ago, long before Bridge-players took up the term for the exact parallel of this operation in their game’.

After the Second World War, Assiac (the pseudonym of Heinrich Fraenkel) organized a New Statesman competition to find a suitable translation of Zugzwang. As reported on page 54 of his book The Pleasures of Chess, the entries included plank-walk, movicide, goose-gang, gadarene-pull and dreadmill. Both squeeze and movebound were submitted, and the latter actually won first prize for Gerald Abrahams. H.G. Hart’s CHESS precedent had evidently been forgotten. Walter Korn went further in his book The Brilliant Touch in Chess (page 72), offering movebound, movestruck, movetight, off tempo, in a jam, in a squeeze and duress. At least part of the intention of all this was to elude a purportedly ugly-sounding German word.

Equivalents were sought in other languages too. In an article on page 173 of the September 1942 issue of the Argentinian magazine Caissa, Carlos Skalicka proposed semi-ahogado (Spanish for semi-stalemate). The same item maintained, on undisclosed grounds, that the term Zugzwang had been invented over 50 years previously by Hermann Zwanzig (1837-1894), and that Dufresne’s opinion was that it had ‘truly enriched the German language’.

A word is normally defined, or at least clearly understood, before it is translated, but with Zugzwang the contrary occurred. In an heretical article ‘That Zugzwang Nonsense!’ on pages 26-27 of the January 1972 BCM Wolfgang Heidenfeld (1911-1980) threw a weighty spanner in the works:

‘The opponent’s Zugzwang – the compulsion (as opposed to the right) to make a move – enables a player to win – or draw, as the case may be – a position which he could not otherwise win or draw. If the opponent had the choice of moving or “passing” at his discretion, there would be no win or draw. Once this criterion is lacking there is no Zugzwang. There may be a complete blockade, with one side powerless to make any useful move – but this is no real Zugzwang.’

On this basis Heidenfeld denied that the Sämisch v Nimzowitsch game featured Zugzwang at all. Observing that in the final position it would be more advantageous for White to move (e.g. 26 Bc1 Bxb1 27 Rgf1) than to pass, he suggested that the ‘Immortal Zugzwang Game nonsense’ had resulted from ‘the vanity of Nimzowitsch’. He also disallowed Alekhine v Nimzowitsch, San Remo, 1930 as an example of Zugzwang, notwithstanding Alekhine’s claim in his second Best Games collection. Similar arguments were outlined by Andy Soltis on page 55 of Chess to Enjoy (New York, 1978), and the current hesitancy over the exact meaning of Zugzwang is highlighted by the contrasting entries for the word in the 1984 and 1992 editions of The Oxford Companion to Chess.

The debate is far from over, but in the meantime some further oddities about the Sämisch v Nimzowitsch game may be recorded here. Although it apparently won no brilliancy prize, Ludwig Steinkohl put it in his 1995 book 99 Schönheitspreise aus 150 Schachjahren, calling the opening the Catalan, rather than the Queen’s Indian Defence. Al Horowitz’s book All About Chess gave it twice, with two different introductions. In presenting the closing position, Chess Techniques by A.R.B. Thomas reversed the colours, stating that Nimzowitsch, as White, won with the concluding move h3. (It is true, however, that in an earlier round the two masters had played the same opening against each other, with opposite colours and a minor transposition, up to White’s eighth move.) Aaron Nimzowitsch Ein Leben für das Schach by Gero H. Marten (page 147) asserted that Sämisch thought for an hour before resigning, whereas on page 443 of Die Hypermoderne Schachpartie Tartakower, a participant in the Copenhagen, 1923 tournament, wrote that Sämisch overstepped the time-limit. Although Tartakower concluded that page with the words ‘The Immortal Zugzwang Game’, they were indented and in quotation marks, not necessarily suggesting that Tartakower himself had originated the epitaph as is sometimes believed.

Just as sacrifices are attractive because possession of material is usually an advantage, the appeal of Zugzwang is that possession of the move is almost invariably desirable. Difficult to define and translate, Zugzwang is, in all its possible forms, easy to enjoy. As the prize-winning Gerald Abrahams suggested on page 38 of Brilliance in Chess (London, 1977), ‘of all chess situations, Zugzwang is the one most likely to stimulate mirth’.




Afterword (C.N. 2929, in May 2003):

Per Skjoldager (Fredericia, Denmark) writes to us as follows:

‘You list many major chess periodicals from which the “Immortal Zugzwang Game” was absent. I think it is even more remarkable that it was also absent from the Scandinavian chess magazines Skakbladet, Norsk Schakblad and Tidskrift för Schack.

You mention Hemmer Hansen, and I can confirm that he did indeed write something similar to the words attributed to him by Nimzowitsch. In an article on the Copenhagen tournament in Jyllands-posten, 12 April 1923 he gave the following account of Nimzowitsch’s win in the game in question:

“His game in Copenhagen against Sämisch is actually of the same rank as Anderssen’s famous Immortal Game. The difference, however, is that while Anderssen was trying to mate his opponent with his combinations, Nimzowitsch tries to paralyse his opponent’s forces. In the game mentioned he sacrifices a piece and with his own five pieces he puts six enemy pieces into such deep disarray that Sämisch resigned the game long before mate was in sight.”

Yet we still lack proof that “Danish chess circles” recognized the game as the “Immortal Zugzwang Game”.

I can also report that Emanuel Lasker annotated the game in De Telegraaf, 2 June 1923. The item was found by Piet Zwetsloot and Wim Nijenhuis. After 25...h6 Lasker wrote:

“In this remarkable position all White’s pieces are stalemated. For example: 26 g4 R5f3! or 26 Kh2 R5f3! So White can only make a few pawn moves. Therefore White resigned here.”

It will be noted that Lasker referred only to a “remarkable position”, whereas Nimzowitsch quoted him as calling the game a “magnificent achievement”. But, of course, this article may not be the only place where Lasker wrote about the game.

The exact date of the game can be mentioned here, i.e. 10 March 1923 according to Jyllands-posten of the following day.

You discussed the varying accounts of how the game ended. This is what appeared in an article in the newspaper Politiken on 11 March 1923:

“Sämisch ponders for so long that he falls into time-trouble. However, his efforts cannot save him from the fateful dilemma and since the loss of the queen is inevitable in only two more moves [sic], he resigns the game, which has lasted for 26 moves in total.”’

We would add that one of the very few chess magazines to publish the score in 1923 was The Chess Amateur. Some eight months after the game had been played the November 1923 issue (page 37) gave the ‘score and notes from an excellent column which seems to be edited by the Hastings Chess Association’. The latter publication was quoted as saying that the game contained ‘a most subtle sacrifice leading to a curious finish’, and the move 25…h6 was given two exclamation marks with the following note: ‘White must either give up the queen (…Rf3 is threatened) or else give up a piece to allow the queen to retreat!’



C.N. 6756 quoted a comment by C.J.S. Purdy on page 34 of the February 1960 Chess World:

Zugzwang just doesn’t happen in a middle-game. There is a win by Nimzowitsch against Sämisch in the middle-game which one annotator has called a “Zugzwang” finish. It is true that any move by Sämisch loses, but he would lose just as surely if his opponent had to move. It is not the compulsion to move that hurts him; his position is lost anyway. So it is no more Zugzwang than any other resignable position.’



From page 67 of Duels of the Mind by Raymond Keene (London, 1991):

‘This incredible game has been hailed as the “Immortal Zugzwang Game”. Chess is a game symbolic of warfare. Once this is accepted, is it too fanciful to imagine that Nimzowitsch’s conduct of this wonderful game was influenced by the trench warfare, the blockades which characterized World War I?’

Yes.



Page 111 of The Mammoth Book of The World’s Greatest Chess Games by G. Burgess, J. Nunn and J. Emms (London, 1998, 2004 and 2010) states:

‘Emanuel Lasker hailed this as the “Immortal Zugzwang Game”.’

As shown in the present article, we are aware of no instance of Lasker’s having used that exact phrase.

(6768)



Addition on 22 July 2011 (two C.N. items published in 1985):

The Oxford Companion to Chess (Oxford, 1984) describes Zugzwang as ‘a position in which each player would obtain a worse result if it were his turn to move than if it were not’. Later, it is remarked that ‘Zugzwangs occur only in the endgame, most frequently in pawn endings, occasionally in endings with knights, and rarely in endgames with line-pieces’.

The Sämisch-Nimzowitsch classic (Copenhagen, 1923) is given with this commentary: ‘White is at a loss for a good move in the final position, but it is not a Zugzwang. Black could lose the move in many ways; he can also make threats, and the position is not even a squeeze’. A squeeze (not a term we knew) is defined on page 321 as ‘a position in which one player must give ground only because he is obliged to move, as distinct from a Zugzwang when whoever has the move would be at a disadvantage. The position White Kd6 and Pc7, Black Kc8 is a Zugzwang: White to play would only draw, Black to play would lose, i.e. having the move would be disadvantageous for both Black and White. On the other hand the position White Kc7, Pb6 and Be2, Black Kc5 and Bc8 would be a squeeze: if Black were to move the pawn could be promoted and if White were to move he could make a waiting move (e.g. Bd3) with the same result; i.e. only Black is at a disadvantage because he has to move’.

In reply to a query as to whether Zugzwang really only occurred in the endgame, David Hooper challenged us to quote a middlegame example. We offered the following, from page 67 of Hugh Myers’ Exploring the Chess Openings (Davenport, 1978):

zugzwang

Myers-Lim, New York 1971

White has just played 36 b3 and gives the following annotation:

‘Black overstepped the time limit. It’s a case of absolute Zugzwang; White wouldn’t be able to win anything with the move, but he wins at least another pawn after any of Black’s 23 legal moves.’

Mr Hooper replied:

‘Your example, Myers-Lim, is certainly not a Zugzwang, for White can win if it is his turn to play (1 Khl). Nor is it a squeeze, for White can build up threats, apart from the fact that being a pawn up one might regard his position as won anyway. After Khl and Rh4 Black might answer 1...Kg8, when White wins by 2 Rxh6 Qxd4 3 Qh7+ Kf8 4 Nxe6+, for example.’

We passed these comments to Hugh Myers, who responded as follows:

‘I strongly disagree with Mr Hooper’s understanding of Zugzwang. It means “compulsion to move”, and common usage has given it a sense of negative consequences as a result of that compulsion. Nimzowitsch, in My System, talks about the position of the pieces of the player who must move, saying that Zugzwang is “when any change in their configuration can only be detrimental. In such a position his condition will get worse step by step until he is forced, by the necessity of making a move, to relax his hold on, or weaken, some key point, and his game collapses”. That means that Zugzwang can be a term applied to more than one particular position; it’s a downhill process in which the obligation to move, as compared to being given a right to pass, results in gradual deterioration of one’s game. However, pure Zugzwang is the unfortunate obligation to move in the culminating position: the player who must move will lose material or be mated (on the move or by the starting of a combination) by his opponent’s next move, even though the opponent would not be able to do either if it were his move in that position.

Mr Hooper’s statement that the final position of Myers-Lim “is certainly not a Zugzwang” is simply incorrect. It is a pure (or absolute) Zugzwang. Mr Hooper introduces two irrelevant factors:

1) “Being a pawn up one might regard his position as won anyway.” Might regard? So what? After going two pawns up, it would be clearly won. That is the result of the Zugzwang: making Black’s position clearly lost (Nimzo: “his game collapses”).

2) If it were White’s move, he could secure a won position by playing Khl (creating the same Zugzwang situation). This doesn’t make the particular position any less a Zugzwang situation. That definition is met by simply this: if it were White’s move, he would win nothing with that move; Black’s move must permit White to win material.

Mr Hooper has nothing to substantiate his very unclear definition of Zugzwang. At least it’s more understandable than “squeeze”, an apparently invented term.’

(923)

From David Hooper:

‘A chess position, examined as if it were White’s turn to play and also as if it were Blacks turn to play, falls into one of three categories according to its time characteristics:

(1) The obligation to make a move does not change the result of the game unfavourably.

(2) The side that has to move, be it Black or be it White, suffers decisive disadvantage because and only because it is his turn to play.

(3) The player to move will on this account alone suffer decisive disadvantage; the opponent to move will suffer no disadvantage thereby.

Category (1) positions occur throughout most of the game; having the move is usually desirable.

In the Companion category (2) positions are called Zugzwangs, and of these we can say, “whoever plays loses”, or “White plays and draws, Black to play loses”, or, “White plays and loses, Black plays and draws”. Neither player can change the result of the game by making threats.

Category (3) positions might well be sub-divided: (3a) those in which there is no other way to win, and (3b) those, such as that given by Mr Myers, in which a win might also be achieved by other means. In the Companion a position of type (3a) is called a squeeze. (3a) is so different from (2) that a separate name seems desirable. For a proper understanding of the endgame it is important to define both these types and to understand the difference between them.

The first use of the word Zugzwang, allegedly originated by Max Lange, needs to be determined – a fitting task for readers of Chess Notes, perhaps. Nimzowitsch, writing in the 1920s, is no doubt correctly quoted by Mr Myers. Later, Rinck attempted a more precise definition, but he used the word “blocus”, not Zugzwang. In 1954 Halberstadt labelled category (3a) Zugzwang and category (2) reciprocal Zugzwang. In 1972 I published an article (EG No. 29) using the words squeeze and Zugzwang. EG is the world’s leading periodical on the subject of basic endgame research and studies, and no reader denied the reality of the different categories. The Companion’s choice of terms, an attempt at standardization, may not meet with universal approval; but it is to be hoped that suitable terms will be established in due course.

Until consensus is reached, and perhaps a name (if required) is found for category (3b), Mr Myers is, of course, entitled to call his position a Zugzwang or any other word he chooses.’

(988)

As noted above, in the 1992 edition of The Oxford Companion to Chess the entries on Zugzwang and squeeze were revised.



See also the article ‘Drohung und Zugzwang’ by H. Keidanz (Keidanski) on pages 248-264 of the July-August 1911 Wiener Schachzeitung, as well as pages 387-388 of the November-December 1911 issue.

Black resigned.

‘One of the most elaborate blockades and Zugzwangs ever’ and ‘altogether a most wonderful conception’. So wrote Bruce Hayden about a game on pages 58-61 of Cabbage Heads and Chess Kings (London, 1960):

1 e4 e5 2 Nc3 Nc6 3 f4 exf4 4 Nf3 g5 5 h4 g4 6 Ng5 h6 7 Nxf7 Kxf7 8 d4 d5 9 Bxf4 dxe4 10 Bc4+ Kg6 11 O-O Bg7 12 h5+ Kh7 13 Be5 Bxe5

The book merely stated that ‘Herr Hartewige’ won the game in Chemnitz in 1901. When Hayden originally published the item (Chess Review, March 1953, pages 76-77), the loser was mysteriously named as ‘Herr Neinzwanger’.

White was Emil Johann Hartewig (1861-1932), and when he annotated the game on pages 174-175 of the June 1902 Deutsche Schachzeitung he identified his opponent as ‘R. F....i’:

A note to 33 b3 in a Morphy v Löwenthal game on page 127 of 500 Master Games of Chess by S. Tartakower and J. du Mont (London, 1952):

‘Reaching a curious case of Zugzwang on an open board.’



In the entry on Zugzwang on page 223 of Dictionary of Modern Chess by Byrne J. Horton (New York, 1959) the word was misspelt four times:

This ‘Jung v Szabados’ position from the 1950s (White to move) has been discussed in a number of C.N. items (see pages 77-78 of Chess Facts and Fables and C.N. 4555).

Publications gave the venue as Hungary, Venice and Dessau, and now Riccardo Del Dotto (Picciorana-Lucca, Italy) adds that August Livshitz offered a fourth version: Reggio Emilia. See, for instance, the second volume of Test Your Chess IQ (Oxford, 1981, page 32 and Oxford, 1989, page 26). Our correspondent also notes that the Zugzwang position had been the subject of compositions by Rinck and Troitzky, and he believes that the ‘Jung v Szabados’ ascription is false.

For further details see his article ‘Smascherato un falso storico?’.

(8403)



Old attempts to explain Zugzwang are always welcome. The following reply to a correspondent comes from page 154 of the September 1902 Schweizerische Schachzeitung:

‘E.H., Lausanne. La signification de Zugzwang est littéralement “contrainte de jouer”. Cela veut dire que les Noirs répondant au 1er coup des Blancs, sont obligés de se mettre sous un mat dont ils ne seraient même menacés s’ils pouvaient déranger aucune pièce.’
