{The Grand-Prix tournament in Jermuk was an unusual event for me. In the first
half I had missed a lot of possibilities, but l after the second rest day luck
was on my side. Before the last round I was trailing the leaders by half a
point and I had White against one of the leaders Peter Leko, who had had an
excellent tournament so far. From childhood I read a lot about such a games:
White is half a point behind and needs a win, Black is leading and will be
satisfied with a draw. Whose task is easier? Which strategy is better to
apply? Polugaevsky-Portisch from the Interzonal Petropolis 1973 was always an
example for me (excellently annotated by the winner in the tournament book).
However, I decided to use another tactic and joined the theoretical discussion.
Das Grand-Prix-Turnier in Jermuk war eine ungewöhnliche Veranstaltung für
mich. In der ersten Hälfte hatte ich eine Vielzahl von Möglichkeiten
ausgelassen, aber nach dem zweiten Ruhetag war das Glück auf meiner Seite.
Vor der letzten Runde lag ich einen halben Punkt hinter den Führenden und
hatte Weiß gegen Peter Leko, einen von ihnen, der bis dahin ein
ausgezeichnetes Turnier gehabt hatte. Von Kindheit an hatte ich eine Menge
über solche Partien gelesen: Weiß liegt einen halben Punkt zurück und
braucht einen Sieg, Schwarz führt und wird mit einem Remis zufrieden sein.
Wessen Aufgabe ist leichter? Welche Strategie sollte man besser wählen?
Polugaevsky-Portisch aus dem Interzonenturnier Petropolis 1973 war immer ein
Vorbild für mich (ausgezeichnet vom Gewinner im Turnierbuch kommentiert).
Doch ich entschloss mich zu einer anderen Taktik und ließ mich auf die
theoretische Diskussion ein.} 1. d4 Nf6 2. c4 e6 3. Nf3 b6 {Peter had chosen
his main opening. Recently he has added the Semi-Slav to his repertoire. Peter
hatte seine Stammeröffnung gewählt. In letzter Zeit hat er seinem Repertoire
auch Halbslawisch hinzugefügt.} 4. g3 Ba6 5. Qc2 {I went for the sharpest
system. Since the games Vallejo-Macieja, Turin 2006 and Gelfand-Aronian,
Dortmund 2006 this system has become very topical. White sacrifices a pawn,
but gets an initiative for it. Ich wählte das schärfste System. Sein den
Partien Vallejo-Macieja, Turin 2006 und Gelfand-Aronian, Dortmund 2006 ist
dieses System sehr aktuell geworden. Weiß opfert einen Bauern, erlangt dafür
aber Initiative.} (5. b3) 5... Bb7 6. Bg2 c5 {[%csl Gc5,Gd4]} 7. d5 exd5 8.

pawn down, but Na5, Nh5 and Bc7 are poorly placed and thus White has full
compensation for the pawn. I was aware that engines don't see a big danger for
Black and this gave me extra confidence and motivation. I was convinced that
my assessment of the position was correct and was eager to prove that a
human's view on a position can sometimes be more precise than a computer's one
(a very unpopular opinion nowadays). Nun hatte ich die Stellung, die ich
spielen wollte. Weiß hat einen Bauern weniger, aber Na5, Nh5 und Bc7 stehen
schlecht, und somit hat er volle Kompensation dafür. Mir war klar, dass
Engines keine große Gefahr für Schwarz sehen, und das gab mir noch
zusätzlich Selbstvertrauen und Motivation. Ich war überzeugt, dass meine
Einschätzung der Position korrekt war und brannte darauf zu beweisen, dass
die Stellungssicht eines Menschen manchmal genauer sein kann als die eines
Computers (eine ziemlich unpopuläre Meinung heutzutage).} Qe7 {Black had
other possibilities, which no doubt will be tested in tournament practice in
the near future. Thus I'll just show a beautiful line, indicated by Sergei
Shipov on his site crestbook.com. This line shows the big potential of White's
position. Scwharz hatte auch andere Möglichkeiten, die man zweifellos in
naher Zukunft in der Turnierpraxis testen wird. Ich werde daher nur ein
schönes Abspiel zeigen, angegeben von Sergei Shipov auf seiner Seite
crestbook.com, welche das große Potential der weißen Stellung zeigt.} (19...
