From page 105 of La Stratégie, March 1913:

underpromotion



On page 176 of Chess Curiosities (London, 1985) Tim Krabbé quoted a position from a USSR correspondence game (Babushkin v Postnikov, 1969-70) featuring what was claimed to be ‘the only knighting on record that was not a check’. We note that the game between Xiu Jun and Vassily Ivanchuk in the 1993 World Team Championship in Lucerne (won by Black in 62 moves) began: 1 d4 d5 2 c4 e6 3 Nf3 dxc4 4 Qa4+ Nd7 5 e4 Nf6 6 Nc3 a6 7 Bxc4 Rb8 8 Qc2 b5 9 Be2 Bb7 10 O-O b4 11 e5 bxc3 12 exf6 cxb2 13 fxg7

13… bxal(N).

Antonio Gude (Madrid) sends this position from a game between Michael Adams and Tony Miles at Tilburg on 17 November 1993:

dia

White played 90 b8(N), and according to the tournament bulletin the game was drawn at move 122. However, Tony Miles (Birmingham, England) informs us:

‘It was actually drawn around move 135, but neither the players nor the computer monitor could keep track during the final time scramble.’

(2031)

Alain Pallier (Avignon, France) offers a further example. The position below occurred at the end of the game between Najdorf and Schweber at Buenos Aires, 1968:

dia

Black having just moved 63...Na6-c5, White played 64 b8(N), and the game was declared drawn.

Two further specimens have come from Alain Pallier:

Vujic v Petrovic, Yugoslav Ladies’ Championship, Kula, 1985

White played 74 f8(N) and won at move 87.

Source: New in Chess, November 1985, page 57.

I. Leventić v J.P. Boudre, European Cup, Luxemburg, 1993

62 b8(N). The game was won by Black at move 81.

(2061)

Regarding the first position in C.N. 2061 above (Vujić v Petrović, Yugoslav Ladies’ Championship, 1985), Emil Smilovici (Nepean, Ontario, Canada) asks whether the full game-score is available.

We can offer only the remaining moves, as published by Tim Krabbé in the source indicated in the earlier C.N. item (New in Chess, November 1985, page 57):

‘and Black resigned; the next move would be mate’.

A large number of specimens of knight promotion without check were given by René Olthof in an article entitled ‘Silicon Curiosities’ on pages 80-83 of the 4/1994 New in Chess.

Julián Alonso Martín (Seville, Spain) forwards us the following position from a 1985 correspondence game between Palevich and Lebelt:

dia

Play went: 1 Nxc4+ dxc4 2 Rd1 exd1(N) 3 Be4 Nxc3 4 Bxa8 Nxa2 5 Bd5 c3 6 Bxa2 c2 7 Bbl Drawn.

The above was published on page 29 of issue 1 of the ‘Especial’ edition of Ocho x Ocho. We should like further details.

(2068)

Jerky Konikowski (Dortmund, Germany) proposes an alternative way for White to draw in the above Palevich v Lebelt position: 1 Rxc4 e1(Q) (1...dxc4 2 Nxc4+ Ka4 3 Nb2+, followed by 4 Nd3.) 2 Rc5 Qe2 (against the threat of 3 Nc4+ and 4 Ra5 mate) 3 Nc4+ Qxc4 4 Ra5+ Qa4 5 Rxa4+ Kxa4 6 Kb2 Kb5.

He also reports that the Palevich v Lebelt position inspired him to compose the following ending, which was published in the 12/1986 issue of Schach-Echo, as well as on page 260 of Schachspiegel 2/1992:

dia

White to move and win

Solution: 1 e7 a1(Q) 2 Bxa1 Rd8 3 exd8(N) Be5 4 Nxc6 Bxa1 5 Nxa7 Bd4 6 Nc8 Bxc5 7 Nb6+ Bxb6 8 axb6 Kb8 9 b7 Kc7 10 Ka7 and wins.

N.N. v F. Präger, (Venue?), February, 1924

There followed 1…Qh8+ 2 e8(Q) Qf6+ Drawn. White could have won with 2 e8(N).

How does White mate in four moves from the position below?

dia

Solution: 1 c8(B) b3 2 Bg4 b2 3 Bd1 Kxb1 4 Bb3 mate.

Source: CHESS, January 1953, page 65, which merely intimated that the problem had been published in Munich circa 1908 and did not identify the composer.

(2811)

The problem was by Oswald von Krobshofer (1883-1960) and, according to secondary sources, was published in the Münchener Neueste Nachrichten in 1908. Our thanks to Ivo Fasiori (Prato, Italy), Michael McDowell (Westcliff-on-sea, England) and Graeme Oswald (Chester-le-Street, England) for this information.

The above comes from page 186 of Chess Curiosities by Tim Krabbé, and Claus van de Vlierd (Oldenburg, Germany) asks whether the full game-score is available.

We note that various databases break off the Kholmov v Ehlvest game in this position, after 40...b5:

See also pages 916-917 of the October 1996 issue of EG, which states that the score only as far as move 42 was given in the 1/1984 issue of Shakhmatny byulleten.

This position (White to move) was given on pages 262-263 of Combination in Chess by G. Négyesy and J. Hegyi (Budapest, 1965). It is described as ‘a possible subvariation’ from the game Haág v L. Szabó, Budapest, 1958, and the moves indicated are 1 Bg1 f1(B), and Black wins.

See also page 193 of Chess Curiosities by T. Krabbé:

In databases the score of the Haág v Szabó game can be found as far ‘63 Ke3 Nxf6 0-1’:

1 e4 e5 2 Nf3 Nc6 3 d4 exd4 4 Nxd4 Bc5 5 Nb3 Bb4+ 6 c3 Be7 7 c4 Nf6 8 Nc3 Bb4 9 Bd3 a5 10 O-O a4 11 e5 Nxe5 12 Nd4 O-O 13 Bg5 Bxc3 14 bxc3 h6 15 Bh4 Ng6 16 Bg3 d6 17 Re1 Re8 18 Rxe8+ Nxe8 19 Rb1 Nf6 20 Bc2 a3 21 c5 dxc5 22 Nb5 Qxd1+ 23 Rxd1 Bd7 24 Nxc7 Rc8 25 c4 Nf8 26 Be5 Be6 27 Nxe6 Nxe6 28 Bf5 Ra8 29 Bc2 Rd8 30 Rxd8+ Nxd8 31 Bf4 Nc6 32 Bc1 Na5 33 Bxa3 b6 34 Bd3 Ne8 35 Bc1 Nd6 36 Kf1 Kf8 37 Ke2 Naxc4 38 Bxc4 Nxc4 39 Kd3 Nd6 40 a4 Ke7 41 Ba3 Kd7 42 f3 Kc6 43 g4 Kd5 44 Bb2 g6 45 Bg7 h5 46 h3 Nc4 47 Bf6 Ne5+ 48 Ke3 Nd7 49 Bd8 c4 50 a5 bxa5 51 Bxa5 Nc5 52 gxh5 gxh5 53 Bc3 Ne6 54 Bf6 Kc5 55 f4 Kd5 56 f5 Nc5 57 Ba1 Ne4 58 f6 c3 59 Kd3 Ke5 60 Ke3 Kf5 61 Kd3 Kf4 62 h4 Kf5 63 Ke3 Nxf6

Is anything more known about the game’s conclusion?

(6514)

Michael McDowell points out that a miniature study by S.G.Belokon quoted on page 310 of Test Tube Chess by A.J. Roycroft (London, 1972) shows promotion to both knight and bishop and the same finish as in the Szabó position.

A five-star book just published is The Art of the Endgame by Jan Timman (Alkmaar, 2011). Chapter five is entitled ‘Knight Promotions’, and we became particularly interested in the pair of compositions on pages 82-83:

dia

‘Herland, Deutsches Wochenschach, 1913. White to play and win’

1 a6 Bg1 2 a7 h2 3 a8(N) h3 4 Nb6 cxb6 5 c7 b5 6 c8(N) b4 7 Nd6 exd6 8 e7 d5 9 e8(Q) and wins.

dia

‘F. Fritz. White to play and win’

1 h4 Ka5 2 h5 Ka4 3 h6 b4 4 h7 b5 5 h8(N) a5 6 Ng6 fxg6 7 f7 g5 8 f8(N) g4 9 Ne6 dxe6 10 d7 e5 11 d8(N) and wins.

Regarding the latter composition, Timman commented:

‘It is unclear when this study was made. In the database it has been adorned with the label “source unknown”.

Who was F. Fritz? He should certainly not be mixed up with Jindřich Fritz ...’

The main historical issue raised by Timman is whether Sigmund Herland was the first to compose such a study, in 1913, or whether the Fritz position antedated it. We offer some jottings.

The Herland study was published on page 128 of the 6 April 1913 Deutsches Wochenschach, with the solution on page 247 of the 13 July 1913 issue.

We note furthermore that the endgame database of Harold van der Heijden has the following study by Hugo Geiger of Munich from page 38 of the February 1920 Deutsche Schachzeitung:

geiger

When the solution was given on page 139 of the June 1920 issue it was remarked that the third promotion to a knight was not necessary, because 11 d8(Q) would win too:

geiger

The Geiger position was also discussed, without identification of him, in T.R. Dawson’s ‘Endings’ column on page 218 of the May 1938 BCM:

dawson

From page 262 of the June 1938 issue:

dawson

Dawson returned to the study on page 310 of the July 1938 BCM:

dawson

As regards the ‘fatal flaw’, the key point is whether the white king is on b1 or c1. The van der Heijden database has both versions, but who first proposed the improvement of placing the king on b1?

The position by L.A. Hulf which was mentioned by Dawson in the June 1938 BCM had appeared on page 299 of the 14 April 1938 CHESS, in Hulf’s ‘End Games’ column:

hulf

The solution was given on page 369 of the 14 June 1938 issue:

Steven B. Dowd (Birmingham, AL, USA) notes that the knight promotion motif was used in a composition by Donald H. Hersom in the 10/1936 Fairy Chess Review. It can be found on-line by copying PROBID='P0553007' into the search-box of the Schwalbe website.

Harold van der Heijden (Deventer, the Netherlands) answers the question in C.N. 7418 about who proposed the improvement (white king on b1, and not c1) in this study from page 38 of the February 1920 Deutsche Schachzeitung: Mikhail Zinar (Ukraine), on page 137 of a book co-written with Vladimir Archakov: Гармония Пешечного Этюда (Kiev, 1990).

From Robert John McCrary (Columbia, SC, USA):

‘What is the simplest or most sparse legal position, in terms of number of units and strength of material, in which the only winning move is promotion to a bishop? In 1969 I composed this pair of positions:

dia

White wins with 1 b8(B). If 1 b8(N) Nf7+ 2 Kg6 Ng5.

dia

Again, promoting to a bishop is the only winning move, although the defenses are different (beginning with 1...Ne7+ 2 Kf6 Kh7).

A related question concerns the simplest or most sparse legal position in which promotion to a bishop is the only way to draw (by self-stalemate.)’

White to move and mate in two

One of our feature articles on the Laws of Chess mentioned that the ‘International Chess Code’ was published, inter alia, on pages 207-224 of Chess for Fun & Chess for Blood by Edward Lasker (Philadelphia, 1942). An extract from the provisions on castling (pages 212-213):

‘The king can be moved to a square adjoining the square he occupies except in the case of castling, which is a combined move of the K and the R, but counts as one move, in which first the K, occupying his own square, is placed on one of the two nearest squares of the same color as his own in the same rank and then the R, towards which the K has been moved, is placed on the next square on the further side of the moved K. Castling is not permitted (a) when either the K or R has been moved previously; (b) when any square between the K and the R is occupied by a man; (c) if the K be in check; or (d) if castling would cause the K to pass over, or occupy, any square on which he would be in check.’

The above position was presented by Jack Straley Battell on page 33 of the February 1955 Chess Review:
