{[Quelle: De Telegraaf 1934/MAY/01; Übers. aus dem Niederländischen TL;
Spielort: Pforzheim] Ist Bogoljubow auf dem Weg, dem Siegeswillen Aljechins
einen ebenso kraftvollen Willen entgegen zu stellen? Sollte man Bogoljubows
Gewinnpartie als einen geglückten Versuch betrachten, sich freizumachen, sich
zu emanzipieren? Gewiss hat Aljechin in diesem Match dominiert, doch gilt dies
nicht für das rein Schachlich-Fachliche, denn sein Partieaufbau - und dies
ist Hauptsache in jeder Auseinandersetzung - ließ die straffe Struktur
vermissen. Auch wurde er oftmals überspielt. Gelang es Bogoljubow nicht schon
einige Male nachzuweisen, dass Aljechins Angriffe kurzatmig waren? Stand der
Weltmeister nicht mehrmals sehr schlecht und bedrängt oder geriet in
Stellungen mit zahlreichen Schwächen in seiner Bauernstruktur? Ohne jeden
Zweifel! Und doch hat er gewonnen. Welche Erkenntnis ist daraus zu ziehen? A)
Dass ihm ein taktisches Können zur Hilfe steht, das sich fast zum Genialen
erhebt. B) Dass er dem Gegner seinen überlegenen Willen aufzuerlegen versteht.
Nach der achten Partie (mit dem grauenvollen Endspiel) fragte mich der heftig
bewegte Bogoljubow: - Glauben Sie, dass man hypnotisiert werden kann? - Aber
Bogoljubow, antwortete ich, das ist doch großer Unsinn. - Nein, erwiderte
Bogoljubow vollkommen ernsthaft, ganz sicher kann man hypnotisiert werden,
zumindest teilweise. Vom ersten Tage an hatte Bogoljubow sich gegen Aljechins
unzähmbare Willenskraft zur Wehr gesetzt, still und unbeholfen, wie es seine
Natur mitbringt, aber deutlich wahrnehmbar für jeden, der "sehen" kann. Er
verteidigte sich gegen Aljechins alarmierende Mitteilungen - z. B. dass er
"die nächste Partie gewinnen wird" - indem er ein satyrisches Gelächter zur
Antwort anstimmte. Bei jedem festlichen Empfang - und diese fanden in jeder
Stadt statt, in die sie kamen - verwahrte er sich gegen Aljechins
eindrucksvolle Rededarbietungen, die immer wieder, auf die eine oder andere
Weise, die Absicht verrieten, ihn, "Boggie", ungünstig zu beeinflussen, indem
er eine gutmütige, ironische Korrektur anzubringen versuchte. Und zum Schluss
verteidigte er sich während der Partie...indem er sich eine große
Sonnenbrille aufsetzte, um Aljechins scharfem Blick zu entgehen. Die zehnte
Partie wollte Aljechin schon um 14 Uhr fortsetzen, damit er rechtzeitig zu
einer Vorstellung von Wagners Siegfried erscheinen konnte. "Siegfried" ist
ganz unbedingt eine imposante Oper. Dies muss "Boggie" zugeben. Doch warum man
ihm aus diesem Grunde die Möglichkeit rauben wollte, sich weiter in Ruhe
seine Hängepartie anzusehen, dies wollte ihm nicht einleuchten.  Aljechin
setzte sich durch und die Partie wurde schon um 14 Uhr wieder aufgenommen.
Doch Bogoljubow rebellierte gegen Aljechins dominierenden Willen und führte
eine ganze Reihe unnötiger Turmzüge aus, die weiter nichts verdarben, außer
Aljechins Vorhaben, den Siegfried zu hören.  Auch in der Partie selbst findet
der aufmerksame Leser eindeutig illustriert: das Ringen zweier Willen.} 1. d4

{There was a special background to this encounter, because at the previous
European team Championship we had surprisingly lost 1.5-2.5 to the Turkish
team, which had been the start of the problems we had then. I myself had also
had White then and had been unable to overcome the resistance of Mustafa
Yilmaz. So now I had to take up arms against Alexander Ipatov. In various
football matches between chess players we had stood together on the same side
of the barricades. This time - for the first time! - we found ourselves
sitting opposite each other over the chess board.  Diese Begegnung stand in
einem besonderen Kontext, denn bei der vorangegangenen Mannschafts-EM hatten
wir gegen die Türken überraschend 1,5-2,5 verloren und damit unsere
damaligen Probleme eingeleitet. Ich selber hatte damals ebenfalls Weiß und
konnte den Widerstand von Mustafa Yilmaz nicht überwinden. Nun bekam ich es
also mit Alexander Ipatov zu tun. In diversen Fußballvergleichen der
Schachspieler standen wir auf derselben Seite der Barrikade. Diesmal saßen
wir uns - erstmals! - auf unterschiedlichen Seiten des Schachbrettes
gegenüber.} 1. c4 c6 2. Nf3 d5 3. d4 Nf6 4. Nc3 e6 5. Bg5 Nbd7 6. e3 Qa5 {
Alexander had moreover recently rarely played the Queen's Gambit and he had
never employed the Cambridge Springs Variation! It was a cunning thought of
his to surprise me in this way. It was his bad luck that I had considered in
some detail these positions after my game against the guru of this variation,
Alexey Dreev (Loo 2014), and had taken another look at my analyses just
shortly before the European Cup.  Alexander spielte zuletzt ohnehin selten
Damengambit und die Cambridge-Springs-Variante hatte er noch nie angewandt! Es
war ja schlau gedacht von ihm, mich auf diese Weise zu überraschen. Sein Pech
war, dass ich mich mit diesen Stellungsbildern nach meiner Partie gegen den
Guru dieser Variante, Alexey Dreev (Loo 2014), ausführlich beschäftigt und
mir diese Analysen erst kürzlich vor dem Europapokal erneut angeschaut hatte.}
7. cxd5 Nxd5 8. Rc1 Nxc3 9. bxc3 Ba3 10. Rc2 b6 {Just at the moment this is
probably the most important branch of a variation which had been introduced
into practice in 2011 by Bart Michiels and refined by the future world
champion (Gelfand - Carlsen, London, 2013).  Das ist die im Moment wohl
wichtigste Verzweigung einer Variante, die 2011 von Bart Michiels in die
Praxis eingeführt und vom späteren Weltmeister ausgefeilt wurde (Gelfand -
Carlsen, London, 2013).} 11. Be2 {There are some subtleties about the bishop
move to d3 which need to be explained, but at the present moment theory is in
favour of the slightly more modest development to e2. Auch zum Läuferzug nach
d3 wäre einiges an Feinheiten zu erklären, aber im gegenwärtigen Moment
spricht sich die Theorie für die etwas bescheidenere Entwicklung nach e2 aus.}
Ba6 12. O-O Bxe2 13. Rxe2 {This is a principled innovation which contains a
fresh way of approaching this position. Up till now, the recapture on e2 here
had always been made with the queen. What could be more natural? Magnus
Carlsen, who had made use of this setup as Black against Boris Gelfand in 2013
in London, later changed sides and won a brilliancy in Shamkir 2014 against
Shakhriyar Mamedyarov by recapturing on e2 with the queen. For my part, in May
of last year I had been unable to find anything convincing here for White. The
conclusions to be drawn from this formed the following logical chain: Black
has strategic advantages on the queenside and in the endgame, i.e. he must
seek for counterplay based on play in the centre and on exchanges. For his
part, White controls the centre and must make use of this for play against the
black king. The capture on e2 with the queen leaves the rook on the c-file
which will soon be opened, requiring it to be exchanged and not favouring the
attack. The concrete checking out of this “theoriy” naturally brought to
the surface some underwater reefs, but on the whole I was convinced of the
value of this idea in practice Das ist eine prinzipielle Neuerung, die ein
neuartiges Herangehen an diese Position beinhaltet. Bis dato hatte man hier
immer mit der Dame auf e2 zurückgenommen. Was könnte es auch Natürlicheres
geben? Magnus Carlsen, der diesen Aufbau 2013 in London gegen Boris Gelfand
noch als Schwarzer vertreten hatte, wechselte später die Seiten und gewann in
Schamkir 2014 gegen Shakhriyar Mamediarov mit dem Schlagen mit der Dame auf e2
eine Glanzpartie. Ich allerdings konnte im Mai vergangenen Jahres hier nichts
Überzeugendes für Weiß finden. Die Schlussfolgerungen daraus bildeten diese
logische Kette: Schwarz hat strategische Vorteile am Damenflügel und im
Endspiel, d. h. er muss ein Gegenspiel suchen, das auf einem Spiel im Zentrum
sowie auf Abtauschen gründet. Weiß seinerseits beherrscht das Zentrum und
muss dies für ein Spiel gegen den schwarzen König nutzen. Das Nehmen auf e2
mit der Dame belässt den Turm auf der sich bald öffnenden c-Linie, was dort
seinen Abtausch fördert und den Angriff nicht begünstigt. Die konkrete
Überprüfung dieser “Theorie” förderte natürlich einige unterirdische
Klippen zutage, aber im Großen und Ganzen war ich vom praktischen Wert dieser
Idee überzeugt.} O-O ({It would be premature to play Verfrüht wäre} 13...
