<Delaying the invasion of the rook at c7 and preventing the invasion of the queen at b6, which, in view of the weakness of the d6-pawn, would have hindered the regrouping of the black pieces.
<For the third time, but by no means the last, the bishop appears at e5. Its blockading strength has grown to the maximum, even though White now penetrates onto the seventh rank.>
<Now the threat of a counterattack on the dark squares restricts the white queen, and does not allow it to go to the queenside. For example, 39.Qa7 Qg3, and White cannot take either the rook or the b7-pawn because of 40..Bd4+ 41.Kh1 Be5 42.Kg1 Bd4+. Nevertheless, Kasparov himself called 39.R1c2 a 'sound time-trouble' move, and an alternative suggestion of his is given at the end of the game.>
<The time has come to switch to more active defence. If White accepts the pawn sacrifice (46.bxa5 bxa5 47.Rxa5) he opens a way for the black rook into his position.>
<Black again sticks to waiting tactics.>
<Breaking the combined 'glances' of the white pieces at f7 (in reserve White still has Be6 in combination with Rc7 and Qa7).>
<Of course, not 58..Qxa7 59.Qxf6+, breaking through the defensive barriers with an easy win.>
<In principle, a major achievement for White. He has forced the exchange of queens and rid himself of the spectre of a counterattack, but... The blockaded nature of the position is retained, and will the exchange advantage suffice for a win?
<At this point White evidently decided that after the exchange of bishops Black would tie up his opponent's forces by a counterattack on the b4-pawn.>
<Winning also a pawn, but as compensation both black bishops become threatening.>
Although later analysis showed that White did not exploit all his chances (thus stronger was 39.h4! Qh6 - if 39..Qd2 40.R1c2 - 40.g3, while in Kasparov's opinion 64.Bxd7 would also have given a win - 64..Rxd7 65.Rc8 Rb7 66.Rfc1 Kf6 67.R1c7 Rb6 68.Ra8 or 65..Ra7 66.Rb8 Ra2 67.Rb1 Kf6 68.Rxb5, and the b-pawn cannot be stopped) Black was nevertheless awarded a special prize for his defensive skill: such was the diversity of defensive ideas that he displayed in this game.>
