Lot
- 1. e2-e4 c7-c5 2. c2-c3
Kasparov chose his favorite opening, the Sicilian Defense , to which the chess program responded with the solid Alapin variant , named after 19th century Russian master Simon Alapin .
- 2.… d7 – d5 3. e4xd5 Qd8xd5 4. d2 – d4 Ng8 – f6 5. Ng1 – f3 Bc8 – g4 6. Bf1 – e2 e7 – e6 7. h2 – h3 Bg4 – h5 8. 0–0 Nb8 – c6 9. Bc1 – e3 c5xd4 10. c3xd4 Bf8 – b4!
A big innovation at this point. Before that you played 10.… Bf8 – e7. Kasparov, who had examined this position in his home analysis, improved the well-known theory with this move and the chess computer was forced to calculate independently. Before that, he had followed the programmed opening moves.

Deep Blue-Kasparov
Position after Black's 10th move |
- 11. a2 – a3 Bb4 – a5 12. Nb1 – c3 Qd5 – d6 13. Nc3 – b5 Qd6 – e7 ?!
This inaccuracy allows White to play his pieces more actively. Instead, moves like 13.… Qd6 – b8 or 13.… Qd6 – d5 came into question, which would probably be better.
- 14. Nf3 – e5! Bh5xe2 15. Qd1xe2 0-0 16. Ra1-c1 Ra8-c8 17. Be3-g5
Black now has a problem, especially with the pinned knight on f6.
- 17.… Ba5 – b6 18. Bg5xf6 g7xf6
Kasparov was not allowed to take it back with the queen on f6 because of 19.Ne5 – d7 with an increase in quality, but Black's king position is now weakened.
- 19. Ne5 – c4! Rf8 – d8
But not 19.… Nc6xd4? 20. Nb5xd4 Bb6xd4 21. Qe2 – g4 + and White wins a piece.
- 20. Nc4xb6 a7xb6 21. Rf1 – d1 f6 – f5 22. De2 – e3!
An excellent field for the white queen.
- 22.… Qe7 – f6

Deep Blue-Kasparov
Position after Black's 22nd move |
- 23. d4 – d5!
A Kasparov-style pawn sacrifice ! Kasparov himself was very astonished by this move and then wrote that he had also played this move himself, but that it would be very unusual for a chess program. White sacrifices his attacked pawn in order to reinforce his attack on the black king.
- 23.… Rd8xd5 24. Rd1xd5 e6xd5 25. b2 – b3! Kg8 – h8?
After this mistake, Black can no longer counter the mate attack . Kasparov would like to use the g-line with his tower, but that will not happen again. Only 25.… Nc6 – e7 !? promised salvation.
- 26. De3xb6 Rc8-g8 27. Qb6-c5
But not 27. Qb6xb7 Qf6 – g5, which threatens mate and at the same time attacks the rook on c1.
- 27.… d5 – d4 28. Nb5 – d6 f5 – f4 29. Nd6xb7
A typical materialistic computer move: White eats an opposing pawn who is completely uninvolved in the action, thus increasing his position evaluation. Deep Blue calculated that Black would not threaten him with a devastating mate attack and expanded his material holdings.
- 29.… Nc6 – e5 30. Qc5 – d5 f4 – f3 31. g2 – g3 Ne5 – d3
31.… Qf6 – f4 was followed by 32. Rc1 – c8 !! Qf4 – g5 33. Rc8 – c5! and white is safe.
- 32. Tc1-c7
32. Rc1-c6? Rg8 – g5 is unclear.
- 32.… Rg8 – e8 33. Nb7 – d6 Re8 – e1 + 34. Kg1 – h2 Nd3xf2
Kasparov is now threatening a single mate, but Deep Blue has everything under control.
- 35. Nd6xf7 + Kh8-g7 36. Nf7-g5 + Kg7-h6 37. Rc7xh7 +

Deep Blue-Kasparov
End position |
Black gave up because after the forced 37.… Kh6 – g6 38. Qd5 – g8 + Kg6 – f5 39.Ng5xf3 Black's mate threat was repelled and White's numerous threats cannot be parried. 1-0
