The players have extracted the maximum from the forces already developed, but the rooks are still out of play, and finding a place for them is the top priority. Viewed in this light, the fact stands out that by capturing on h4 Black has secured the g-file for a rook. Spassky appears not to have grasped this feature of the position, as otherwise, for better or worse, he would have exchanged on c5, so as to open the b-file if Black recaptured with the pawn. On the other hand if a black piece appeared on c5, White could send his a-pawn into battle.} 17. a4 {Diagram [#] When the game was over, I discovered that this move had astonihed those present. Indeed, its drawback is obvious, the d4-square becomes the property of the white pieces. But only in name. I would add, White cannot derive any benefit from stationing his queen on, let us say, a rook on this square. What of the knight, a piece which is especially well placed on blockade squares of this type? In the present case the knight is denied the possibility of going to d4, as it is occupied first and foremost with defending the e5-pawn. Thus, Black's hands are freed for operations in the g-file. Examining the way the game continues from here, we should not forget about one threat that is constantly in the air - the threat to bring Black's bishop to g7, winning what is the pride but the weakness of White's position, his pawn on e5.} c4 18.

I that position the difference in strength between the bishop and knight would be great, and Black's pawn weaknesses would be irreparable. The most intriquing thing is that Spassky saw 18.Bf5 and demonstrated it immediately after the game was over. Nevertheless, he decided against transferring his bishop to h3 (should he decline to capture on f5). On h3 the bishop would be rather unaesthetically placed, resembling some odd kind of overgrown pawn. Yet it would be fulfilling an important function as the defender of the pawn on g2.}) 18... a6 $1 {Properly speaking, this unobtrusive move contains the essence of Black's plan.
