Paul F Johner X Aoron Nimzowitsch - Dresden 1926

Johner, Paul F2414Nimzowitsch, Aaron25770–1E41Dresden2Dresden04.1926
The Players Paul Johner (1887–1938) was a Swiss player and musician, who won or shared the Swiss Championship six times. His best success was his victory in a quadrangular tournament in Berlin 1924, where he came ahead of Rubinstein, Teichmann and Mieses. Aron Nimzowitsch (1886-1935) was one of the strongest players in the world during the 1920s and was also influential as a thinker and writer. He was born in Riga and rose to prominence before the First World War. The war interrupted his career for six years but when Nimzowitsch was able to resume international competition he rapidly advanced into the world elite. After a succession of tournament victories, his challenge for the World Championship was accepted by Capablanca in 1926. However, Nimzowitsch was unable to raise the necessary money and when the world title passed to Alekhine in 1927, the new champion preferred to play a title match against Bogoljubow (some have said that this was because Alekhine regarded Nimzowitsch as the more dangerous opponent). After 1931 he could not maintain his level of play and was no longer a realistic title contender. Nimzowitsch fell ill in 1934 and died from pneumonia some months later. Nimzowitsch was, along with Réti, one of the most prominent members of the "Hypermodern" school of chess, which introduced many new ideas into the game, especially in the area of opening play (see the introduction to Game Réti - Bogoljubow, for more details). Nimzowitsch’s influence on opening theory was especially profound and a number of opening lines bear his name. The two most important are the Nimzo-Indian Defence (1. d4 Nf6 2. c4 e6 3. Nc3 Bb4), and the French Defence line 1. e4 e6 2. d4 d5 3. Nc3 Bb4, which is called the Nimzowitsch Variation in most non-English speaking countries. Both are still in everyday use. Nimzowitsch wrote three important books of which two, My System (1925) and Chess Praxis (1929) are regarded as classics of chess literature and are still in print. The Game This is probably one of Nimzowitsch’s most creative achievements at the chessboard. As early as move 12 he implements a plan that shocks the chess world. The incredible thing is that it seems to work! Certainly Johner has no answer to the unique problems facing him. He looks on as a virtual spectator as his pawns are blocked and then his position dismantled bit by bit. A game of pure joy! 1.d4 f6 2.c4 e6 3.c3 b4 Nimzowitsch’s own defence, which is generally known as the Nimzo-Indian (the name "Nimzowitsch Defence" is reserved for 1. e4 Nc6, even though this is a far less important opening). In the nineteenth century virtually all the top players would have played 3...d5 here (if they hadn’t already played ...d5 on move one), controlling the centre in a classical way by occupying it with pawns. However, Nimzowitsch discovered another way to play for Black, which seems very normal now, but at the time was quite revolutionary. His concept was to control the centre with pieces rather than pawns, a kind of long-distance command, which has the advantage of retaining much flexibility. This theory was one of the key ideas of the Hypermodern school of chess, led by Richard Réti and Nimzowitsch himself. 4.e3 0-0 5.d3 c5 6.f3 c6 7.0-0 xc3 8.bxc3 d6 9.d2!

Nimzowitsch’s main idea was first to restrain, then blockade and finally destroy. Here Black starts the restraining part of the plan. The only possible action for White in this position is on the kingside. He would like to expand there with g4, so Black basically takes steps to prevent this. The fact that the queen blocks the bishop for the moment is quite irrelevant. The whole picture will be seen in a few moves’ time. In My System Nimzowitsch writes "Black sees in White’s kingside pawns (f-, g- and h-pawns) a qualitative majority. The text move involves a complicated method of restraint." 12...e8! 13.g4 13.f5 g5 13...f5 14.d5 14.dxc5!? dxc5 15.d5+ xd5 16.cxd5 e7 17.d1 d6 14...e7 15.g5 Leads to petrification-Nimzowitsch Führt zu Versteinerung -Nimzowitsch 13.h3?

Larsen g4+ 19.xg4 hxg4 20.axb6 gxh3 21.gxh3 h4 22.g3 It's not easy to prove a clear win for Black - Larsen. 18...a5! It's easier to defend the weakness on b6 than the weakness on a4. Compare Spassky,B-Fischer,R (05) Wch28-Reykjavik 1972, 0-1/ (27) b6 ist leicht zu decken. Vgl. Spassky,B-Fischer,R (05)/Wch28-Reykjavik/ 1972/0-1/27/ 19.g1 h6 20.f1 d7 21.c1 ac8 Black has enough play on the kingside, so he is not worried about the centre being closed by d4-d5. Schwarz braucht die Abschließung durch d4-d5 nicht mehr zu fürchten, denn er hat genug Spiel am Königsflügel. 22.d5 h8 23.d2 23.g2 g8 24.f2 g5-+ 23...g8 Now comes the attack. 24.g2 g5 25.f1 g7 26.a2 f5 27.h1 cg8 28.d1 gxf4! 29.exf4 c8 30.b3 a6 31.e2 31.d2 g6! 32.e1 g4+ 33.hxg4 hxg4+ 34.g2 xc4! 35.xc4 e3-+ 31...h4! Black’s positional masterpiece has been completed, and he now completely dominates the board. The rest is of the game is simply tactics. Tactics tend to flow freely from a position of strength, and this game is no exception. 32.e3 32.d2 c8! 32...f5? 33.d1! c8 34.f1 33.xe4 33.d1 xh3! 34.xh3 f5+ 33...f5! 34.f2 xh3+! 35.xh3 g4# 32...c8 33.c2 xh3! 34.xe4 34.xh3 f5+ 35.h2 g4+ 36.h3 f2+ 37.h2 h3# 34...f5 The best, since h5-h4 can no longer be stopped; after the fall of the Bh3 the defence has become hopeless. Das Beste, denn nun ist h5-h4 nicht mehr aufzuhalten; nach Fall des Bh3 ist die Verteidigung eben hoffnungslos geworden. 35.xf5 xf5 36.e2 h4 37.gg2 hxg3+ 38.g1 h3 39.e3 h4 40.f1 e8! FOO41...Nxg2 42.Rxg2 Qh1+ 43.Ke2 Qxg2+! 40...e8! White resigned. 41.e1 f3+ 42.d1 h1+ . Lessons from this game: 1) The Nimzo-Indian is one of the soundest defences to 1. d4. 2) The art of restraint is a very important concept. In My System Nimzowitsch asks himself the question "Was ...Qd8-d7-f5-h7 an attacking manoeuvre?", before answering in his own way "Yes and no (!). No, since its whole idea was to restrain White’s kingside pawns. Yes, since every restraining action is the logical prelude to an attack, and since every immobile complex tends to be a weakness and therefore must sooner or later become an object of attack." Who can argue with this logic? 3) Positional domination is often the precursor to a decisive tactical flourish. In this game Black only begins the tactics around move thirty. Ten moves later White is forced to resign. 0–1
