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...
