Kasparov-Deeper Blue, Match 1997
Games Three And Four

 
The Lull: Mid-Match Draws
Controversies and re-assessments from game two overshadow Kasparov's strong but unrewarded play.

Games three and four were drawn; in both cases Kasparov managed to achieve a superior position, but was unable to convert his advantage to a win. In a sense both games were overshadowed by the aftershocks of game two.

Kasparov returned to the road less travelled in the opening, aiming for a setup related to a number of positions found in the English and Reti openings. His main point, as in game 1, was to exploit Deeper Blue's preference of bishops over knights. 9. Ng5 followed by harrassment of the light-squared bishop with the kingside pawns, and the consequent solidification of the kingside, allowed White to concentrate on operations on the queenside.

The first hint of trouble for Deeper Blue was 16. .. Kh8, clearly indicating that the machine was incapable of finding a course of action. White proceeded to open the queenside with control of the b-file, and then astutely took control on the king's wing as well with 21. f4.

Since the pawn on a3 was of little consequence, White is happy to have another open file. Unfortunately, 24. Ra2 was inferior to 24. Rb7. While White continued to put excellent pressure on Black's position with strangling moves such as 36. f6 and 37. h4, Black was eventually able to draw by giving back the pawn with 40. .. Bc7 41. Nxc7 Rxc7 42. Rxa5 Rd8. White is unable to punish the king's corner shuffle.

For game four, Kasparov uncharacteristically adopts the Caro-Kann (1. .. c6), noted for its quiet and drawish qualities. Kasparov is clearly playing the opponent and not the board, as he has never used this opening against a human competitor.

After 16. .. f6 17. exf6, Black is forced to take with the queen and accept the doubled isolated pawns on the g-file; 17. .. gxf6 18. g5 is just too strong for White.

After 20. Nd1, White's position looks extremely good: Black is cramped, and appears to have no means to free his pieces, while White could continue to strangle the ebony army. But after the pawn sacrifice 20. .. e5!!, a different picture emerges, one in which Black's pieces are mobile and coordinated, and it is not obvious how White is to convert the pawn advantage into a win.

Thereafter, White seems to go astray positionally. First he opens the position to his disadvantage after 28. bxc6 bxc6, and allows Black to seriously weaken the White pawn structure with 30. .. Qxe3 31. fxe3. 32. Rh3 is also a strange, inexplicable move.

Immediately after the conclusion of the first time control, the machine reclaims its material equality with 41. Rxg7+, but its three pawns are three islands whereas Black's are merely two islands. Nonetheless, the well-advanced e- and h-pawns gained Black enough counterplay to draw.
