{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 ProzeЯ dauert seine Zeit. Heute kцnnen sich sogar Klubspieler ein
Lдcheln nicht verkneifen, wenn sie einige der primitiven Tricks sehen, die in
den groЯen Partien der Vergangenheit zum Erfolg fьhrten. Jede Schachepoche
hatte indes einige weitsichtige Vertreter, die zur Theorie unseres
altehrwьrdigen Spiels beigetragen haben. Aber nur die grцЯten Meister waren in
der Lage, ganze Generationen zu ьberspringen und Ideen zu entwickeln, die
ihrer Zeit weit voraus waren. Ein schцnes Beispiel dafьr 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 Erцffnungsfьhrung wьrde von den Vertretern der klassischen Schule
sicher aufs Schдrfste verurteilt werden. Ein rьckstдndiger Bauer auf c6,
entwickelte aber unkoordinierte Figuren, fehlende Kontrolle im Zentrum –
natьrlich waren diese Faktoren Aljechin bewuЯt. Aber er setzte auf die
versteckte Dynamik der schwarzen Stellung. Er wuЯte, wie schwer es ist, sogar
fьr den stдrksten Spieler, taktisches Potential gegen positionelle Merkmale
aufzuwiegen, das Risiko, das sie eingehen, korrekt einzuschдtzen. Aber die
Bereitschaft, in einer gefдhrlichen 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

mochte seinen wichtigen weiЯfeldrigen Lдufer nur ungern gegen den
randstдndigen Springer auf a6 abtauschen. Sein klassischer Sinn verlangte nach
einer strengen Bestrafung fьr Aljechins antipositionelle Erцffnungsbehandlung.}

{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 hollдndische Mysterium Max Euwe 
(1901-1985, Weltmeister 1935-1937) wird von der Schachwelt allgemein
unterbewertet - auЯer natьrlich 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 fьr Mathematik
zu verdienen. Sein Schachtalent kamm bereits in frьhen Jahren zum Vorschein,
aber da er sich im Kreise der Schachamateure bewegte, schloЯ er sich selber
aus dem Liste der ernsthaften Kandidaten fьr den Titel des Weltmeisters aus.
Wie sollte sich auЯerdem jemand ohne beeindruckende Turniersiege als
ernstzunehmender Herausforder bewerben kцnnen? Dies war der Grund, warum er in
der Schachцffentlichkeit auf Skepsis stieЯ, als er genau das versuchen wollte.
Angesichts der groЯartigen Resultate in den frьhen dreiЯiger Jahren wollte
niemand glauben, daЯ der Hollдnder etwas anderes als Kanonenfutter fьr den
Champion sein wьrde. Aljechin teilte offenbar diesen kategorischen Standpunkt,
obwohl Euwe gnerell gegen einen bestimmten Spieler ganz auЯergewцhnlich gute
Ergebnisse erzielt hatte - gegen Alexander Aljechin. Ein erstes Match, 1927
gespielt, kurz vor Aljechins Triumph ьber Capablanca, endete mit einem sehr
knappen Vorsprung fьr den Russen - 5,5:4,5 (+3,-2,=5), nachdem Aljechin seinen
Gegner in der sehr verdдchtigen 10 Partie eingelullt hatte. Die
Turnierbegegnungen bewiesen ebenfalls keinerlei Ьberlegenheit seitens Aljechin.
Nur in dem Rematch von 1937 gelang es Aljechin dank gewissenhafter
Vorbereitung das hollдndische Geheimnis zu entmystifizieren.  In Wirklichkeit
kann dieses Phдnomen auf rationale Art erklдrt werden. Euwe war der erste
Spieler, der Erцffnungen mit wissenschaftlicher Grьndlichkeit untersucht hat.
Sein Repertoire war so aufgebaut, daЯ Aljechin keine Gelegenheit bekam, seine
ganzen schachlichen Fдhigkeiten zu entfalten. Wenn man Euwes Fдhigkeit zur
prдzisen Berechnung, sein Gespьr fьr Initiative und seine auЯergewцhnliche
psychische Vefassung aufaddiert, ist klar, woher Aljechins Probleme kamen.
Gezwungen, ohne Initiative spielen zu mьssen, machte der Russe eine Menge
Fehler, meistens aufgrund von Ungeduld. Als Aljechin zwei Jahre nach dem
Verlust des Titels an Euwe den Rьckkampf gewann, vermutete jeder, des Ergebnis
des ersten Wettkampfes sei einfach durch schlechte Form und unprofessionelle
Wettkampfauffassung seitens Aljechins zustandegekommen. ich persцnlich bin
anderer Ansicht und glaube nicht, daЯ diese Faktoren das Ergebnis beeinflusst
haben. Ein Jahr zuvor, 1934, spielte Aljechin einen schlechten Wettkampf gegen
Bogoljubow, aber das Endresultat spiegelte nicht die Qualitдt 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 Rьckstand 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
