der Anziehende sofort
nach Vorteil im Zentrum streben sollte. Reti hat diese althergebrachte
Weisheit nicht akzeptiert - im Gegenteil rechnete er damit, daß die
gegnerischen Zentrumsbauern im Verlaufe der Partie vortreffliche Zielscheiben
für Angriffe durch die fianchettierten Läufer abgeben würden. Diese
revolutionäre Strategie hatte eine vernichtende Wirkung auf die Spielweise von
vielen starken Spielern, die bei solch ungewöhnlichen Verhältnissen auf dem
Schachbrett regelmäßig den Wendepunkt der Partie verkannten. Sogar der große
Capablanca mußte 1924 beim Turnier in New York eine peinliche Niederlage gegen
Retis Lieblingsverteidigung einstecken und zum ersten Mal in zehn Jahren die
Worte "Ich gebe auf" aussprechen.  Heutzutage ist Retis Eröffnung, mit
zahlreichen Modifikationen, natürlich ein regelmäßiger Gast bei Turnieren
jeder Kategorie. Allerdings wird selten ein Spieler, der mit dem sehr
beliebten Zug 1.Nf3 seine Partie beginnt, an die mutige Herausforderung denken,
mit der das visionäre tschechische Genie vor 75 Jahren die Schachwelt
aufrüttelte.} 1. g3 e5 2. Nf3 e4 3. Nd4 d5 4. d3 exd3 5. Qxd3 Nf6 6. Bg2 Bb4+
