True, Deep Blue has played the opening in a way which appears very odd to human eyes, because it doesn't fit any of the normal patterns for playing with Black against the English Opening. Ideally, White would like to set his kingside pawns in motion, but it isn't easy to achieve this. The f-pawn is pinned, and White cannot unpin it by moving his queen, because then f3 would be hanging. Moreover, there is no attractive square to put the queen (ironically, the move a2-a3 cuts out a possible Qd2). Of course, White could play 15 g4 Bg6 16 f4, but then 16...exf4 17 Bxf4 Rae8 is fine for Black; he intends ...b5 and the f2-knight is badly placed.

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.

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.

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.

Ndf1 dxe4 {Now that the knight has moved away from d2, the possibility of Nc4 disappears and so this exchnage becomes feasible. However, the kniught is already on its way to f5 by a different route.

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.

Der Computer versucht verzweifelt, den weißen Plan zu stören. Obwohl dieser Zug weitere Schwächen am Königsflügel bewirkt, bekommt Schwarz aktiveres Figurenspiel. Das ist eine kritische Phase.

Andererseits konnte Schwarz seinen Läufer auf das ideale Feld d5 bringen. Von dort deckt der Läufer die Bauern c6, f7 und e4 und wirkt auch noch nach a2 und b3, in Richtung des weißen Königs. Entlang der b-Linie kann der schwarze Turm wirken. Schwarz hat keine direkte Schwäche, deswegen gestaltet sich ein weiteres Vorkommen schwierig für Weiß. Sein einziger Plan besteht darin, seine Bauern am Königsflügel nach vorne zu bringen und so Linien gegen den schwarzen König zu öffnen (mit g2-g4-g5, h2-h4-h5 und dann entweder h5-h6 oder g5-g6). Allerdings ist diese Idee schwierig umzusetzen, denn mit dem Vorrücken der Bauern ergeben sich für Schwarz (insbesondere für die schwarze Dame) neue Ziele für Gegenspiel. In der Partie arrangiert Kasparov zunächst seine Dame und seinen Turm um, bevor er zum Vormarsch der Bauern übergeht. Allerdings ist mir nicht klar, ob diese Umgruppierung wirklich die weiße Figurenstellung verbessert. Ich untersuche daher 26.Kb1:} 26. Qc5+ (26.

Any human Any human under such assault by a world champion would be staring at his own king trying to figure out how to get away. Instead, Deep Blue ignored the threat and quite nonchalantly went hunting for lowly pawns at the other end of the board. In fact, at the point of maximum peril, Deep Blue expended two moves - many have died giving Kasparov even one - to snap one pawn. It was as if, at Gettysburg, General Meade had sent his soldiers out for a spot of apple-picking moments before Beckett's charge, because he had calculated that they could get back to their positions with a half-second to spare. In humans, that is called sangfroid. And if you don't have any sang, you can be very froid. But then again if Meade had known absolutely - by calculating the precise trajectories of all the bullets and all the bayonets and all the cannons in Pickett's division - the time of arrival of the enemy he could, indeed, without fear, have ordered his men to pick apples. Which is exactly what Deep Blue did. It had calculated every possible combination of Kasparov's available moves and determined with absolute certainty that it could return from its pawn-picking expedition and destroy Kasparov exactly one move before Kasparov could destroy it. Which it did. It takes more than nerves of steel to do that. It takes a silicon brain. No human can achieve absolute certainty because no human can be sure to have seen everything.

White's basic plan is to play d4 and then Sbd2-f1-g3. This securely defends his central pawn structure, while making it possible for his remaining pieces to be developed. The current thinking is that Black should obstruct this plan, and the best way to do this is to adopt the Zaitsev System, in which Black plays Kasparov wählt eine etwas antiquierte und passive Verteidigung, die Smyslov-Variante. Der Grundplan von Weiß besteht darin, d4 und anschließend Sbd2-f1-g3 zu spielen. Damit wird seine Bauernstruktur im Zentrum sicher verteidigt, während gleichzeitig die übrigen Figuren entwickelt werden können. Die herrschende Meinung ist, daß Schwarz den Plan mit dem Zaitsev-System (9... Lb7 10.d4 Te8 11.Sbd2 Lf8) durchkreuzen sollte. Der Druck auf e4 macht 12.Sf1 unmöglich, da 12...exd4 einen Bauern gewinnt. Also muß der Springer auf d2 bleiben. Das wiederum blockiert den Läufer auf c1 und erschwert die weiße Entwicklung.

However, the machine's play in this game shows that Deep Blue suffers from this defect far less than other computers. Deep Blue blockiert das Zentrum, auch wenn das für den menschlichen Spieler Vorteile bringen soll. Die weitere Partieführung zeigt, daß dieser Rechner weit besser in solchen Stellungen klarkommt als die anderen Schachprogramme.} Ne7 17. Be3 {This is a theoretical position which has occurred a number of times in grandmaster chess. The earlier games suggest that White is slightly better, but with very accurate play Black retains equalising chances. The first point to note is that Black faces more problems on the queenside than the kingside. The e7-knight can move to g6, when Black has sufficient minor pieces to defend the kingside. The queenside, on the other hand, is looking a little bare. White's aim is to play a4 and b4. If Black is forced to play ... c4, then White will have a virtually guaranteed advantage. He can double or even triple on the a-file, and Black will probably be forced to concede the a-file. In view of Black's total lack of counterplay elsewhere, this could be very unpleasant for him. Moreover, the move ...c4 opens up the e3-a7 diagonal for White's bishop, which would then control squares in the very heart of Black's position. As Black's dark-squared bishop is locked away on f8, there would be no means by which Black could contest this control. It follows that Black must avoid meeting b4 by ...c4. This implies that his queen and rooks belong on the queenside, supporting the c5-square and being prepared to seize open files if pawn exchanges occur. Das ist eine theoretische Stellung, die häufig genug im Großmeisterschach vorgekommen ist. Die früheren Partien legen nahe, daß Weiß etwas besser steht, aber mit genauem Spiel behält Schwarz Ausgleichschancen. Man sollte sich als erstes vergegenwärtigen, daß Schwarz am Damenflügel die größeren Probleme besitzt. Der Springer auf e7 kann nach g6 ziehen, wonach Schwarz genügend Leichtfiguren hat, um den Königsflügel abzusichern. Am Damenflügel dagegen sieht es karger aus. Weiß will a4 und b4 spielen. Falls Schwarz gezwungen ist, ...c4 zu spielen, hat Weiß fast immer einen Vorteil. Er kann auf der a-Linie verdoppeln oder sogar verdreifachen, so daß Schwarz gezwungen ist, diese Linie aufzugeben. Angesichts des Fehlens jeglichen Gegenspiels ist das sehr unangenehm. Ferner öffnet der Zug ...c4 die e3-a7-Diagonale für den weißen Läufer, der anschließend die wichtigsten Felder der schwarzen Stellung kontrolliert. Da der schwarzfeldrige Läufer auf f8 eingesperrt ist, kann Schwarz wenig dagegen unternehmen. Aus all dem folgt, daß Schwarz es vermeiden muß, auf b4 ...c4 spielen zu müssen. Also muß er seine Dame und die Türme am Damenflügel behalten, um das Feld c5 zu stützen und die offenen Linien zu besetzen, falls Bauern abgetauscht werden.} Ng6 {This is not really wrong, although other players have given preference to arranging the queenside pieces, for example Das ist nicht wirklich schlecht, obwohl andere Spieler einen anderen Aufbau bevorzugen, z.B.} (17...

By giving up a pawn, Black solves both these problems at a stroke. The c7-knight can move to e6, and then either to f4 or to c5 and then e4.
