{Analysing the games of the old champions we notice that archaic technical
methods have been slowly replaced by more sophisticated approaches. This
process always takes a long time, and today even a club player can't help
smiling when confronted with some of the primitive tricks that led to success
in the great games of the past. Every chess epoch had its visionary
contributors to the theory of our ancient game, but only the greatest
champions were able to jump through the generations, demonstrating ideas that
were far ahead of their time.  Wenn wir die Partien der alten Meister
analysieren, fallen uns mitunter archaisch anmutende technische Methoden auf,
die inzwischen durch weitaus anspruchsvollere Verfahren ersetzt worden sind.
Dieser Prozeß dauert seine Zeit. Heute können sich sogar Klubspieler ein
Lächeln nicht verkneifen, wenn sie einige der primitiven Tricks sehen, die in
den großen Partien der Vergangenheit zum Erfolg führten. Jede Schachepoche
hatte indes einige weitsichtige Vertreter, die zur Theorie unseres
altehrwürdigen Spiels beigetragen haben. Aber nur die größten Meister waren in
der Lage, ganze Generationen zu überspringen und Ideen zu entwickeln, die
ihrer Zeit weit voraus waren. Ein schönes Beispiel dafür finden wir in der
folgenden Partie.} 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Qb3 dxc4 5. Qxc4 Bg7 6. Bf4

Rab8 {[#] Black's opening would have been cursed by the founders of the
classical school. A backward pawn on c6, developed but uncoordinated pieces,
lack of control in the centre. Naturally Alekhine was aware of these factors,
but he was betting on the hidden dynamism of Black's position. The complexity
of comparing positional qualities and tactical potential makes it very
difficult, even for the strongest players, to evaluate the risk they are
undertaking. But the readiness to remain at the cutting edge can be amply
rewarded if the opponent misses the crucial moment of the explosion!  Die
schwarze Eröffnungsführung würde von den Vertretern der klassischen Schule
sicher aufs Schärfste verurteilt werden. Ein rückständiger Bauer auf c6,
entwickelte aber unkoordinierte Figuren, fehlende Kontrolle im Zentrum –
natürlich waren diese Faktoren Aljechin bewußt. Aber er setzte auf die
versteckte Dynamik der schwarzen Stellung. Er wußte, wie schwer es ist, sogar
für den stärksten Spieler, taktisches Potential gegen positionelle Merkmale
aufzuwiegen, das Risiko, das sie eingehen, korrekt einzuschätzen. Aber die
Bereitschaft, in einer gefährlichen Lage zu verweilen, kann gut belohnt werden,
besonders wenn der Gegner den kritischen Augenblick der Explosion nicht
erkennt.} 14. Bd3 (14. Bxa6 Qxa6 15. Nc5 {was an alternative, but even Euwe

positioned black knight on a6. His classical sense demanded severe punishment

mochte seinen wichtigen weißfeldrigen Läufer nur ungern gegen den
randständigen Springer auf a6 abtauschen. Sein klassischer Sinn verlangte nach
einer strengen Bestrafung für Aljechins antipositionelle Eröffnungsbehandlung.}

It would seem that White has avoided the worst, but despite many exchanges and

so aus, als hätte Weiß das Schlimmste überstanden, aber trotz der vielen
Abtausche und einer annehmbaren Materialbilanz ist die Stellung für ihn in

{The Dutch enigma Max Euwe (1901 - 1985, World Champion 1935 - 1937) was
always underestimated by the chess world - except possibly in his native
Holland. He was never keen to join the club of professional players and
preferred to make his living through the less ambitious but more stable job of
professor of mathematics. His chess talent became evident at quite an early
age, but by staying inside amateur circles he excluded himself from the list
of serious candidates for the World Championship title. Apart from that, how
could anyone launch a real challenge without impressive tournament victories?
That is why when Euwe eventually decided to give it a try this was greeted
sceptically by the chess public. In view of Alekhine's magnificent results in
the early thirties nobody could believe that the Dutchman could assume
anything but cannon fodder for the champion. Alekhine obviously shared this
categorical point of view, although Euwe did usually get exceptionally good
results against one player - Alexander Alekhine. A first match, played in 1927,
just before Alekhine's triumph over Capablanca, ended with a very modest
advantage for the Russian - 5.5:4.5 (+3, -2, =5) - after Alekhine hoodwinked
his opponent in the very suspicious 10th game. Their tournament encounters
also didn't convincingly prove Alekhine's superiority. Only in the rematch in
1937, with the help of scrupulous preparation, was Alekhine at last able to
solve the Dutch enigma. This phenomenon has in fact a rational explanation.
Euwe was the first player to study openings with scientific precision. His
repertoire was designed to prevent Alekhine from unfolding his best chess
qualities. If you add Euwe's talent for precise calculation, his sense of
initiative plus his outstanding nervous constitution, you can see where
Alekhine's problems came from. Forced to play without the initiative, the
Russian made many mistakes, mainly due to psychological impatience. Two years
after losing his title to Euwe, when he won the rematch, everyone assumed that
the result of the first match was purely due to bad form and a casual approach
on the part of Alekhine. But I personally think that these factors had little
to do with the outcome. One year before, in 1934, Alekhine played quite a poor
match against Bogoljubov, but the final score did not reflect the quality of
the chess played: 15.5:10.5! After all Alekhine in poor form was still
Alekhine! In his first challenge match Euwe, after a disastrous start (+1, -4,
=2), was desperately trying to catch up, but Alekhine was able to maintain his
lead. Before the following game the score was 10.5:8.5. Euwe badly needed
another win to stay in the match, which was scheduled for 30 games with a tie
favouring the reigning champion.  Das holländische Mysterium Max Euwe 
(1901-1985, Weltmeister 1935-1937) wird von der Schachwelt allgemein
unterbewertet - außer natürlich in seinem Heimatland Holland. Er war nie
begierig professionell Schach zu spielen, zog es aber dann doch vor seinen
Lebensunterhalt weniger ambitioniert aber solider als Professor für Mathematik
zu verdienen. Sein Schachtalent kamm bereits in frühen Jahren zum Vorschein,
aber da er sich im Kreise der Schachamateure bewegte, schloß er sich selber
aus dem Liste der ernsthaften Kandidaten für den Titel des Weltmeisters aus.
Wie sollte sich außerdem jemand ohne beeindruckende Turniersiege als
ernstzunehmender Herausforder bewerben können? Dies war der Grund, warum er in
der Schachöffentlichkeit auf Skepsis stieß, als er genau das versuchen wollte.
Angesichts der großartigen Resultate in den frühen dreißiger Jahren wollte
niemand glauben, daß der Holländer etwas anderes als Kanonenfutter für den
Champion sein würde. Aljechin teilte offenbar diesen kategorischen Standpunkt,
obwohl Euwe gnerell gegen einen bestimmten Spieler ganz außergewöhnlich gute
Ergebnisse erzielt hatte - gegen Alexander Aljechin. Ein erstes Match, 1927
gespielt, kurz vor Aljechins Triumph über Capablanca, endete mit einem sehr
knappen Vorsprung für den Russen - 5,5:4,5 (+3,-2,=5), nachdem Aljechin seinen
Gegner in der sehr verdächtigen 10 Partie eingelullt hatte. Die
Turnierbegegnungen bewiesen ebenfalls keinerlei Überlegenheit seitens Aljechin.
Nur in dem Rematch von 1937 gelang es Aljechin dank gewissenhafter
Vorbereitung das holländische Geheimnis zu entmystifizieren.  In Wirklichkeit
kann dieses Phänomen auf rationale Art erklärt werden. Euwe war der erste
Spieler, der Eröffnungen mit wissenschaftlicher Gründlichkeit untersucht hat.
Sein Repertoire war so aufgebaut, daß Aljechin keine Gelegenheit bekam, seine
ganzen schachlichen Fähigkeiten zu entfalten. Wenn man Euwes Fähigkeit zur
präzisen Berechnung, sein Gespür für Initiative und seine außergewöhnliche
psychische Vefassung aufaddiert, ist klar, woher Aljechins Probleme kamen.
Gezwungen, ohne Initiative spielen zu müssen, machte der Russe eine Menge
Fehler, meistens aufgrund von Ungeduld. Als Aljechin zwei Jahre nach dem
Verlust des Titels an Euwe den Rückkampf gewann, vermutete jeder, des Ergebnis
des ersten Wettkampfes sei einfach durch schlechte Form und unprofessionelle
Wettkampfauffassung seitens Aljechins zustandegekommen. ich persönlich bin
anderer Ansicht und glaube nicht, daß diese Faktoren das Ergebnis beeinflusst
haben. Ein Jahr zuvor, 1934, spielte Aljechin einen schlechten Wettkampf gegen
Bogoljubow, aber das Endresultat spiegelte nicht die Qualität der Partien
wider - 15,5:10,5. Auch in schlechter Form war Aljechin immer noch Aljechin. 
Im ersten Wettkampf versuchte Euwe nach einem katastophalen Start (+1,-4,=2)
verzweifelt seinen Rückstand auszugleichen, aber Aljechin war in der Lage, den
Vorsprung zu halten. Vor der nachfolgenden Partie stand es 10,5:8,5 und Euwe
brauchte dringend einen Sieg, um im Match zu bleiben, das auf 30 Partien
