Königsindisch-Partien. Danach verschwand das Abspiel mit 10.Be3 praktisch für
über 30 Jahre in der Mottenkiste bis es besonders von Kortschnoi
wiederentdeckt und regelmäßig gespielt wurde.} f5 11. f3 f4 12. Bf2 g5 13. Nd3
Nf6 14. c5 Ng6 15. Rc1 {So wie Weiß spielt, macht der Bf2 keinen Sinn. Der B
könnte genauso gut auf d2 stehen und Weiß hätte ein wichtiges Tempo gespart.

Generell gilt: In allen Stellungen dieser Art kann Schwarz ohne Nachdenken
oder Durchrechnen immer dieses Bauernopfer bringen und hat mindestens
Kompensation, eher mehr. Die Voraussetzung dafür ist, daß eine weiße Figur auf
f2 steht, denn sonst hat Weiß evtl. die Möglichkeit h2-h3. Falls Weiß keine
Figur auf f2 stehen hat, also h2-h3 spielen kann, muß Schwarz in der Lage sein,
möglichst bald auf h3 entscheidend eine Figur opfern zu können, am besten den
Bc8 (d7). Andernfalls bleiben die Linien am Königsflügel geschlossen und der
Angriff ist beendet.} 20. hxg3 fxg3 21. Bxg3 Nh5 {[%csl Rf4,Rg3][%cal Yd8g5]
Multimedia Dateien nicht kopiert Kramnik: Natürlich hat Schwarz genügend
Kompensation für den Bauern. Aber Weiß viele Verteidigungsmöglichkeiten und
die Stellung ist nicht so klar wie es vielleicht aussieht.} 22. Bh2 $2 {
[%csl Rc1,Rd2,Re3,Rf2,Rf4,Rg3,Rg5,Rh4] Hier steht der B ganz schlecht.} Be7 {
[%cal Ye7g5,Rg5c1] Schwarz verstärkt in der Folge in Ruhe seine Stellung.} 23.
