[%mdl 5] Esta jogada, introduzida com sucesso por Capablanca no Torneio de
Siesta de Budapeste em 1928, representa uma continuação um tanto arriscada,
mas também eficaz, da jogada das brancas 5.c3, e tem sido chamada de variante
da Siesta desde então. Por muito tempo não foi muito bem recebido. Na
segunda metade da década de 1940, entretanto, foram descobertos caminhos para
Schwarz para um contra-jogo eficaz, de modo que o interesse por ele aumentou
rapidamente. Até agora não foi possível encontrar uma refutação dessa
variante..} ({A sequela calma} 5... Bd7 {foi jogado entre esses dois oponentes

pretas têm um par ativo de bispos e uma boa chance de ocupar o arquivo
eletrônico. O peão f4 também contribui para o fato de que as brancas estão
em pior situação: torna Bc1 um bispo "ruim" e enfraquece as casas brancas.

menos. Isso o obriga a agir com energia. (N)} 15. Nd2 $6 {Após esse movimento

1932 ist besonders interessant, weil die beiden Gegner, Aljechin und Euwe,
unabhängig voneinander Anmerkungen für das Turnierbuch verfaßten. Es ist
spannend, ihre Ergebnisse zu vergleichen. Euwe spielte 18...e6. Über den Wert
dieses Zuges sind sich die Kommentatoren nicht einig.  Euwe schreibt: <=>Mit
diesem Zug kommt Schwarz in Vorteil."  Aljechin dagegen behauptet: <=>Schwarz
beachtet nicht die Pointe des letzten weißen Zuges und sollte nunmehr
verlieren. Nach 18...Td7 nebst Turmverdoppelung auf der d-Linie wäre die Sache
für Weiß noch immer nicht leicht gewesen."  Wer hat recht?  19.Sf4xe6 
Aljechin schreibt: <=>Durch diese überraschende und recht verwickelte
Kombination wird endlich der materielle Vorteil des Weißen gesichert."  Euwe
sagt: <=>Eine glänzende Konzeption ..." und erörtert die Annahme des Opfers.
Ich ziehe diese Ausführungen zu seiner nächsten Bemerkung. 19. ...    Lb7xd5? 
Ich zitiere zunächst Aljechins Bemerkung: <=>Auf 19...fe6: würde 20.Tf4 Dg5 21.
h4 Le7 22.d6! usw. mit leichter Abwicklung folgen. Am kompliziertesten würde
sich dagegen das Spiel nach 19...Td5: gestalten. Die Hauptvariante darauf
würde lauten 20.Sc7 Td7! 21.Tf4 Dh3 22.Se4! Lg5 (22...Le4: 23.Te4: Tc7: 24.Dd6
usw.) 23.d5!!, und wie auch immer Schwarz spielen mag, Weiß behauptet zum
mindesten seinen Mehrbauern bei abgewickeltem Spiele."  Hören wir jetzt Euwe:
<=>Dies führt zu klarem Nachteil. Die Hauptvariante nach Annahme des
Springeropfers lautet 19...fe6: 20.Tf4 Dg5 21.Se4 Le7 22.d6 Ld6: (falls 22...
Le4:, so 23.de7:) 23.Sd6: De7 24.Tf7 Dd6: 25.Dd6: Td6: 26.Tb7: Td4: 27.Tc1 usw.
19...Td5: war hier geboten. I 20.Sd5:? Ld5: (natürlich nicht 20...De4:?? 21.
Sf6:+) , und Weiß kann entscheidenden Materialverlust nicht vermeiden. II 20.
Sc7 Td7 A) 21.Sa8:? Le4: 22.Te1 Le7!, und Schwarz gewinnt. B) 21.Tf4 Dh3 22.
Se4 Ba) 22...Le4:? 23.Te4: Tc7: 24.Dd6 Df5 25.Tae1 Tcc8 26.Tf4 mit Vorteil für
Weiß. Bb) 22...Lg5 23.d5!! Td5: 24.Sd5: Ld5: 25.Dd6! Td8 26.Dc7 Td7 27.Dc8+
Kg7 28.Td1 Le4: 29.Tf7:+!! Kh6 30.Th7:+! Kh7: 31.Td7:+, und Weiß gewinnt. 
Diese beiden trickreichen Varianten, die von dem russischen Analytiker Sozin
erarbeitet worden sind, scheinen anzuzeigen, daß sich das Spiel des Schwarzen
in einem verzweifelten Zustand befindet. Schwarz hat jedoch eine viel stärkere
Fortsetzung zur Verfügung: Bc) 22...Td4:!! 23.De1 (und nicht 23.Sf6:+ Kh8! mit
Gewinn der weißen Dame) 23...Le5 24.Th4 Te4:! 25.Te4: Lc7: gefolgt von 26...
Le4:, und Schwarz hat eine Figur gewonnen (Weiß kann sich nicht mit 26.Te8+
Te8: 27.De8:+ Kg7 aus der Affäre ziehen, denn nun gibt es keine ausreichende
Verteidigung.). III 20.g4 Df3 21.Tf4 Td4:!! (viel stärker als 21...Dh3 22.f3)
22.Tf3: Tb4: 23.Tf6: Tg4:+ 24.Kf1 La6+ 25.Se2 Le2:+ (25...Te8 ist auch gut
genug) 26.Ke2: Te4+ gefolgt von 27...Te6:."  Es wird bestimmt anregend sein,
das Analysewerk dieser beiden Giganten näher zu betrachten, die nicht nur auf
Grund ihrer Spielstärke, sondern auch geradewegen der Qualität ihrer
literarischen Hinterlassenschaft einen legendären Ruf genießen.  Unbestreitbar
ist zunächst, daß Euwe mit seiner fleißigeren und genaueren Arbeit die
Ausführungen Aljechins widerlegt; nach 22...Td4: ist Weiß verloren. Es ist
nicht das erste Mal, daß wir bei Aljechin ein ganz übertriebenes Vertrauen in
die Stichhaltigkeit der eignen Kombinationen und in die kombinatorischen
Möglichkeiten seiner Stellungen feststellen.  Euwes Ausführungen werden nicht
dadurch entwertet, daß sich ein taktischer Fehler in eine seiner Varianten
findet. Im Abspiel II A kann Weiß in der Schlußstellung nach II Aa) 22...Le7
-Diagramm- mit 23.Dc4 Widerstand leisten: II Aa1) 23...La8: 24.Dc8+ Td8 (Nach
24...Kg7 25.Da8: hat Weiß natürlich auch nichts zu fürchten) 25.Df5: gf5: 26.
Te7: mit Vorteil für Weiß. II Aa2) 23...Lf3 24.d5 mit unklarer Lage.  Stärker
als II Aa) 22...Le7 ist nämlich II Ab) 22...Td4:, und Schwarz hat eine
Gewinnstellung: II Ab1) 23.Db3 Lc6, und die Drohung 24...Df3 hat entscheidende
Kraft. II Ab2) 23.Db5 Lf3 (23...Db5: 24.Sb5: Tb4 25.Sa7: ist nicht klar) 24.
Df5: gf5: gefolgt von Td4-d2 (25.Te3 Lc6), und Schwarz steht auf Gewinn. 
Dennoch war ich von Euwes Arbeit genauso enttäuscht wie von Aljechins
Ausführungen. Der damalige Weltmeister übersah 22...Td4:, und dadurch stürzte
sein Gedankengebäude zusammen. Gegen solche taktischen Übersehen ist niemand
gefeit. Viel bedenklicher scheint mir die Äußerung, nach 18...Td7 nebst
Turmverdoppelung auf der d-Linie <=>wäre die Sache für Weiß immer noch nicht
leicht gewesen." Aljechin scheint zu glauben, daß Weiß auf Gewinn stehe. Davon
kann natürlich keine Rede sein.  Die Behauptung Euwes, nach 18...e6 habe
Schwarz Vorteil, hat mich jedoch ebenfalls außerordentlich verblüfft. Nachdem
er erkannt hatte, daß Aljechins taktischer Lösungsversuch unzureichend ist,
hätte er sich doch die Frage vorlegen müssen, welche Ergebnisse ruhigere
Fortsetzungen zeitigen, wenn er zum Verständnis der Stellung vordringen wollte.
Ich sehe zwei für Weiß erwägenswerte Abweichungen von der Folge 19.Se6: Td5:
20.Sc7. I 19.Tae1 an Stelle von 19.Se6:. Jetzt droht schon 20.Se6: mit
entscheidender Kraft; Schwarz ist zum Schlagen auf d5 gezwungen. 19...Ld5:
scheitert an 20.Sfd5: ed5: 21.Tf4 Dg5 22.h4, und Schwarz verliert eine Figur;
19...ed5: ist nötig. Jetzt erhält Weiß mit 20.T4e2 -Diagramm nach 20.T4e2-
eine sehr befriedigende Stellung: A) 20...Tac8 21.Sb5. Nun scheitert 21...Tc4
an 22.Te8+; Schwarz ist in Schwierigkeiten. B) 20...Dd7 21.Sd3. Weiß bringt
seinen Springer nach e5 und hat ein sehr bequemes Spiel. C) 20...Kg7 21.Sb5.
Auch in dieser Stellung hat Weiß besimmt nichts zu befürchten.  Mit 19.Tae1
hätte Weiß einen kleinen Vorteil erlangen könne. II Nach 19.Se6: Td5: muß Weiß
natürlich mit 20.Sf4 auf die Verteidigung seiner Königsstellung sinnen. Der
Turm des Schwarzen muß von d5 zurückweichen, und dann folgt 21.d5. A) 20...
Tdd8 21.d5 Lc3: (21...a5 kann mit 22.Db6: Lc3: 23.Te7 pariert werden) 22.bc3:
g5 (22...Ld5: 23.Sd5: ergibt eine klare Remisstellung) 23.Sh5, und Weiß hat
keine Probleme: Aa) 23...Ld5: 24.Dd4 usw. Ab) 23...Td5: 24.Tae1 Tdd8 25.Dd4
usw. Ac) 23...Df3 24.De7 usw. Ad) 23...Dg6 24.g4. Weiß steht nicht schlechter.
B) 20...Td7 ist gefährlicher für Weiß: 21.d5 Lc3: (21...a5 ist keine
Verbesserung; Weiß antwortet 22.Da4) 22.bc3: g5 23.Sh5 Df3 (23...Ld5: wird mit
24.Dd4 pariert; nach 24...Dg6 25.g4 hat Weiß nichts zu befürchten), und nun:
-Diagramm nach 23...Df3- Ba) 24.g4 Td5: 25.Tae1 Td1, und Schwarz gewinnt. Bb)
24.Tae1 Dh5: 25.Te8+ Te8: 26.Te8:+ Kg7 27.Df8+ Kg6 28.Dg8+ Kf5 29.c4 Td5:, und
Schwarz gewinnt.  Dennoch hat Weiß eine Auskunft. Bc) 24.Te7 Bc1) 24...Te7: 25.
De7: ist natürlich ungefährlich für Weiß. Bc2) 24...Ld5: 25.Sf6+ Kg7 26.Sd5:
oder 25...Df6: 26.Td7: Df3 27.Td5:, und Weiß hält remis. Bc3) 24...Tad8 Bc31)
25.Td7: Td7: 26.De4 (Auch nach 26.Dg4 Dg4: 27.Sf6+ Kg7 28.Sg4: Td5: hat Weiß
Sorgen) 26...De4: 27.Sf6+ Kg7 28.Se4: Td5:. In diesem Endspiel hat Schwarz
gute Gewinnaussichten. Bc32) Sofortiges 25.De4 ist viel stärker; nach 25...De4:
(25...Dh5: scheitert natürlich an 26.Td7: Td7: 27.De8+) 26.Te4: Ld5: 27.Te5
muß Schwarz um das Remis kämpfen. Bc4) 24...Td5: Bc41) 25.Tb7: Td1+ 26.Td1:
Dd1:+ 27.Kg2 Dd5+ 28.f3 Db7: 29.Dd4 f5 30.Df6 Df7 31.Dg5:+ Kh8 32.Dd2 Tf8.
Schwarz hat einige Gewinnaussichten. Bc42) 25.Sf6+ Df6: 26.Tb7: Df3 27.De7.
Weiß hat nichts zu befürchten.  Ich fasse zusammen: Nach 19.Se6: Td5: hat Weiß
in 20.Sf4 eine zum Remis ausreichende Verteidigung.  Es ist interessant zu
konstatieren, daß die Schwächen in Aljechins und Euwes Kommentierungsarbeit
recht ähnlicher Natur sind: Eingleisigkeit der Betrachtungsweise und Fixierung
auf die eigenen taktischen Möglichkeiten liegen bei beiden vor.} Bxd5 $2 (19...

{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
angesetzt war.} 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 dxc4 {The Slav Defence was

jungen Keres (erst 23 Jahre alt) mit dem äußerst erfahrenen Matchspieler Euwe

Euwe's sense of initiative hasn't betrayed him. Whether you believe it or not,
detailed analysis has produced a clearly negative result for Black! The
homeless king, an advanced raider on g7, combined with other specific factors
of this position, have created a unique explosive mixture, one that leaves
Black hopeless in face of White's quickly developing attack. Was soll aber nun
an dieser Stellung so schlecht sein? Auf den ersten Blick ist es gar nicht so
einfach, auch nur eine kleine Kompensation für die Minusfigur zu finden. Die
schwarzen Streitmächte sind mobilisiert, diejenigen seines Gegners sollten
nicht sofort zuschlagen oder ernsthafte Drohungen aufstellen können. Aber das
ist alles Illusion! Euwes Sinn für die Initiative hat ihn nicht in Stich
gelassen. Ob Sie es glauben mögen oder nicht: die detaillierte Analyse der
Stellung hat ergeben, daß Schwarz auf Verlust steht. Der heimatlose König, der
Kommandobauer auf g7, zusammen mit anderen spezifischen Merkmalen der Stellung,
haben eine explosive Mischung geschaffen, eine, die Schwarz hoffnungslos dem
rasch entwickelnden gegnerischen Angriff ausliefert.} Bd6 {What else? At least

dangerous initiative on the kingside, and it seems that his plan is going to
work. What can be done to prevent the simple attack on h7 with Rh4 and Qh5?
Pushing the pawn from h7 to h6 is not a defence because of Bxh6, and the black
king, left without pawn protection, will be an easy target for the white army.
Does it mean that Black's whole strategy, based on a solid positional
foundation, was a mistake? Of course not - counterattack is the answer! In
einer aggressiven Eröffnung hat Weiß einen Bauern geopfert und dafür eine
gefährliche Initiative am Königsflügel erhalten. Und es sieht ganz danach aus,
als würde die Sache klappen. Was kann Schwarz unternehmen, um den direkten
Angriff auf h7 mit Th4 und Dh5 zu parieren? Der Bauernzug h7-h6 hat keinen
Verteidigungswert, weil dann sofort Lxh6 kommt und der schwarze König, ohne
seinen Bauernschirm, ein einfaches Ziel für die weißen Streitkräfte böte.
Bedeutet das also, daß die gesamte schwarze Strategie, die auf einem festen
positionellen Fundament aufgebaut ist, etwa fehlerhaft war? Natürlich nicht –
die Antwort lautet Gegenangriff!} b5 $3 {[%cal Yd8b6,Yb6g1] One can argue that
such moves are even nicer than beautiful sacrifices. Spotting a weakness on d4
Black forces his opponent to moderate his attacking plan. With an activated
black queen White doesn't feel safe anymore and discovers that his position is
quite vulnerable behind its shiny front. Ich habe das Gefühl, daß ein solcher
Zug vielleicht noch schöner ist als ein spektakuläres Opfer. Euwe hat erkannt,
daß die Schwäche von d4 den Gegner zwingen kann, seine Angriffspläne zu zügeln.
Angesichts einer aktiven schwarzen Dame wird sich Weiß nicht mehr so sicher
fühlen, sondern vielmehr erkennen, daß hinter der glitzernden Fassade seine
Stellung doch etwas wacklig ist.} 17. Rh4 Qb6 18. e5 $1 {An excellent

evaluation of the actual quality of the move - after perfect defence by White
Black would probably lose all his advantage. Two exclamation marks for the
brilliancy of this idea. The white queen is temporarily moved to a passive
position, the black rook will rush to the second rank and the combination of
Q+R+B will start chasing the white king, who was so far a distant observer of
the shells crashing around his counterpart. At the same time just one knight
on e8 is, for a few precious moments, able to keep his king out of trouble.
But the price for all these accomplishments is - a full rook! ?!! Das
Fragezeichen gilt der tatsächlichen Qualität des Zuges – nach perfekter weißer
Verteidigung würde Schwarz nämlich seinen ganzen Vorteil wahrscheinlich
verlieren. Die zwei Ausrufezeichen sind für die glänzende Idee. Die weiße Dame
wird für den Augenblick auf ein passives Feld gelockt, während der schwarze
Turm auf die zweite Reihe stürmt. Gleichzeitig wird die Angriffstruppe von
Dame, Turm und Läufer auf den weißen König gesetzt, der bislang aus sicherer
Entfernung die Einschläge um seinen weißen Gegenpart betrachten konnte. Dabei
reicht der einsame Springer auf e8, für einige wertvolle Augenblicke die
Stellung um den schwarzen König dicht zu halten. Der Preis für diese ganzen
Schätze ist allerdings ein ganzer Turm!} (22... Qd5 23. Re4 {I think now

{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

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.}

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