Nbd2 O-O 9. h3 Bh5 {By a slightly riundabout route we have reached a position which has occurred many times in master and grandmaster chess. White's basic plan is to gain space in the ecntre with e4. Black will sooner or later have to deal with the threat of e5, either by moving his minor pieces out of the way, or by playing ...e5 himself. In the latter case, there will be a slight weakness on f5 which might be able to exploit by Nh4-f5. At the moment this last manoeuvre is impossible, because the f3-knight is pinned, but this explains why one often sees the odd-looking move Qe1 in this system: White wants to support the push of his e-pawn, while at the same time freeing his knight from the pin. Auf Umwegen haben wir eine Stellung erreicht, die man in vielen Meister- und GM-Partien findet. Der weiße Plan besteht darin, im Zentrum Platz mit e4 zu gewinnen. Schwarz muß früher oder später mit der Drohung e5 fertig werden, indem er entweder seine Leichtfiguren aus dem Weg räumt oder selber ...e5 spielt. Im zweiten Falle entsteht eine leichte Schwächung des Feldes f5, die Weiß mit Sf3-h4-f5 ausnützen könnte. Im Augenblick ist das Manöver natürlich unmöglich, da der Springer gefesselt ist. Aber man versteht, warum der Weißspieler in diesem System häufig zum merkwürdig aussehenden Zug De1 greift: Weiß will den Vorstoß des e-Bauern unterstützen und gleichzeitig den Springer von der Fesslung befreien.} 10. e3 {A very unusual move, indeed I can find no examples of it from practical play. The normal moves here are 10 e4 and 10 Qe1. Of the two, I would judge 10 e4 to be the more flexible. In this way White can reserve the option of either Qe1 or Qe2, depending on Black's reply. The merits of 10 e3 are rather hard to find; Kasparov soon adopts the Qe1 and e4 plan, but having lost a tempo in the process. Perhaps his idea was simply to take DB out of its opening book. Ein sehr ungewöhnlicher Zug, für den ich kein Beispiel in praktischen Partien finde. Die normalen Züge sind hier 10.e4 und 10.De1. Den ersten halte ich für den flexibleren. Weiß hält sich je nach schwarzer Erwiderung die beiden Optionen De1 oder De2 offen. Der Vorteil von 10.e3 ist nicht leicht zu erkennen. Kasparov wählt den Plan De1 nebst e4, aber er hat dabei ein Tempo verloren. Vielleicht wollte er lediglich Deep Blue aus dem Eröffnungsbuch werfen.} h6 {Kasparov's deviation at once earns its reward. Instead of putting the extra tempo to use by developing queenside counterplay, for example by 10...a5, the computer makes a pawn move which is worse than useless, because it weakens the kingisde slightly. In a few moves we will see the importance of this. Now that the extra tempo has been handed back, the balance again slightly favours White and now the computer is on its own. Kasparovs Abweichung trägt sofort Früchte. Statt das Extratempo für die Entwicklung von Gegenspiel am Damenflügel, etwa mit 10...a5, zu nutzen, macht der Rechner einen Zug, der schlimmer als wertlos ist, weil er den Königsflügel etwas schwächt. In einigen Zügen werden wir sehen, warum das so wichtig ist. Somit hat Weiß das Extratempo zurückerhalten, und die Stellung ist günstiger für Weiß, besonders weil der Computer eigenständig spielen muß.} 11. Qe1 Qa5 {The play of DB in the phase of the game leaves much to be desired. It quite reasonably plans ...Ba3 to exchange off the active bishop on b2, but this plan is easily countered and then the queen is doing little on a5. Die Spielweise von Deep Blue in dieser Partiephase läßt viel zu wünschen übrig. Der vernünftige Plan ...La3 mit Abtausch des aktiven Läufers auf b2 wird leicht pariert, und danach hat die Dame keine Zukunft auf dem Feld a5.} 12. a3 Bc7 $6 {And this is very odd. There are two possible reasons behind this move. First of all, it may simply be anticipating e4-e5 by White; secondly, DB may want to have its queen defended in case of a line such as Ein merkwürdiger Zug, für den ich zwei mögliche Gründe sehe. Zunächst einmal kann er in Erwartung eines weißen Bauernvorstoßes e3-e4-e5 gespielt worden sein; zum anderen könnte Deep Blue seine Dame decken wollen, um Varianten wie} (12... Rad8 13. Bxf6 Nxf6 14.

Thus Black has to play ...Bg6 in advance, ready to meet Nh4 by ...Bh7.

Having pushed both e- and g-pawns, the f5-square has become a serious weakness. If White could plant a knight there, then the game would be decided. However, DB isn't as stupid as that; there is no straightforward route by which a knight can reach the key square. Nevertheless, this long-term weakness remains a lasting burden for Black. Das sieht alles für das menschliche Auge ziemlich schrecklich aus. Durch den Vorstoß der e- und g-Bauern ist das Feld f5 sehr schwach geworden. Kann Weiß einen Springer dort plazieren, wäre die Partie bereits entschieden. Ganz so dumm ist Deep Blue freilich nicht. Es gibt für den Springer keinen direkten Weg zum Schlüsselfeld. Dennoch bleibt die langfristige Schwäche eine bleibende Last für Schwarz.} 15. e4 {Kasparov at once takes steps to fix the weakness on f5.

However, ...c5 is hard to arrange because of the pressure on d5, and if Black exchanges first on e4, then the route Nc4-e3-f5 is opened up for the knight on d2. We can see how, time and time again, Black's naturalplans are frstrated because they would seriously expose the weakness on f5. Endlich findet Deep Blue einen Plan, wie er Gegenspiel erhalten kann. Allerdings ist der Plan in dieser Stellung nicht sehr effektiv. Die natürliche Fortsetzung wäre ...a4, um b4 zu provozieren, wonach ...c5 folgt. Allerdings läßt sich ...c5 wegen des Drucks auf d5 nur schwer durchsetzen, und wenn Schwarz zunächst auf e4 tauscht, dann ist der Weg für Sd2-c4-e3-f5 offen.

The f2-pawn is quite hard to defend, and until White nullfifies the pressure against it along the b6-f2 diagonal, the knight cannot hop into f5. Kasparov's idea is Nd2-c4; then, if Black wants to mainatin the pressure against f2 he must play ...Qa7, but White continues with b4, exploiting the line-up of a1-rook with the enemy queen, and Black is in trouble. Schwarz hat eine gute Methode gefunden, den Springer von f5 fernzuhalten, jedenfalls vorübergehend. Der f2-Bauer läßt sich schwer verteidigen, und bevor Weiß den Druck auf der b6-f2 Diagonale neutralisiert hat, kann der Springer nicht nach f5 hüpfen. Kasparovs Idee ist Sd2-c4; will Schwarz danach den Druck auf f2 aufrechterhalten, muß er ...Da7 spielen, aber Weiß setzt mit b4 fort, und da der a-Turm die Dame im Auge hat, gerät Schwarz in Schwierigkeiten.} g4 {The computer desperately seeks to disturb White's plan.
