1. d4 Nf6 2. Nf3 d5 3. c4 e6 4. Nc3 dxc4 5. e4 Bb4 6. Bg5 c5 7. Bxc4 cxd4 8.
Nxd4 Bxc3+ 9. bxc3 Qa5 10. Bb5+ Nbd7 11. Bxf6 Qxc3+ 12. Kf1 {The opening line
chosen by the programs is a very critical one for Black with a bad score - The
gewahelte Eroeffnungsvariante is insbesondere fuer Schwarz sehr kritisch mit
einem schlechten Score} gxf6 {Black last book move} 13. h4 Qa5 14. Rh3 {
White last book move} e5 {Not only for computers a logical move as it seems
as if White is forced to play 15.Bxd7 but in reality it's completely wrong to
give square free for white's knight. Necessary was 14...a6 - Nicht nur fuer
Computer eine logische Fortsetzung, denn scheinbar ist 15.Lxd7 erzwungen.
Trotzdem war es voellig falsch, das Feld f5 fuer den weissen Springer
freizumachen. Notwendig war 14...a6} 15. Nf5 {
A very fine piece sacrifice - Ein sehr huebsches Figurenopfer} Qxb5+ 16. Rd3 {
With the threat Nd6 winning black's queen - Mit der Drohung, durch Sd6 die
schwarze Dame zugewinnen} Qa6 17. Kg1 {I think it's no exaggaration to say
that White has already reached a won position - Ich glaube, dass man ohne zu
uebertreiben sagen kann, dass Weiss eine gewonnene Stellung erreicht hat} Rg8
18. Rc1 {Despite long analysis I could not find a way for Black to save the
game - Trotz langer Analysen konnte ich fuer Schwarz keine Verteidigung mehr
finden, um die Partie zu retten} Qxa2 19. Rc7 Qe6 20. Qc2 {
Wins material - Gewinnt Material} Kd8 21. Nd6 Qxd6 {
21...Qg4 does not work on account of 22.Rg3 - 21...Dg4 scheitert an 22.Tg3} 22.
Rxd6 Re8 23. Rd3 Re6 24. Rg3 Re8 25. Qc4 Rb8 26. Rc3 {A good example to
demonstrate that one wrong move often is decisive - Ein gutes Beispiel, dass
ein einziger falscher Zug genuegt, die Entscheidung zu bringen} 1-0
