7. d5 Nh5 8. Qd2 f5 9. O-O-O f4 {In the present game Black
associates this move with the idea of playing his bishop to
h4 followed by the advance of his g-pawn, thus neutralizing
White's initiative on the kingside.} 10. Bf2 Bf6 11. Nge2 {
Black was threatening by 11...Bh4 to exchange the
dark-squared bishop, which with his pawn configuration
would be to his advantage.} Bh4 12. Bg1 g5 $2 {Black
carries out his plan too directly, allowing White to seize
the initiative on the queenside. 13.c5 should have been
prevented be 12...Na6 or 12... Nd7.} 13. c5 g4 14. Kb1 gxf3
15. gxf3 Na6 16. c6 $1 Nf6 $2 {A serious mis take, leading
to a decisive weakening of Black's queenside. He should
have played} (16... bxc6 17. dxc6 Qe8 {attacking the c6
pawn.}) 17. cxb7 Bxb7 18. Ng3 {White decided on this move
very quickly, after easely establishing that} (18. Ng3 fxg3
19. hxg3 Bxg3 20. Qg5+ Kh8 21. Qxg3 {would leave the black
king in an extreamly insecure position. It is unpleasent
for Black to allow the knight in at f5, and therefore})
(18. Ng3 Bc8 { suggests itself. Then White had calculated
that he would win by} 19. Bxa6 Bxa6 20. Nf5 {with two
threats - 21.Nh4 and 21.Qg2 (on 20...Nh5 he has the
decisive 21.Qg2+ Kh8 22.Qg4}) 18... Bc8 {When Black played}
(18... Bc8 { White realized that on} 19. Bxa6 Bxa6 20. Nf5
{there ist the simple reply} Ne8 {After lengthly reflection
he decided to return the knight to e2, in order to initiate
play on the queenside.}) 19. Nge2 Nc5 (19... Nd7 { followed
by 20...Nac5 or 20...Nb6 would have heen better.})
20. Bxc5 $1 { It was a pity to give up this important
bishop, but concrete calculation showed that Black would be
unable to defend his pawn at c5.} dxc5 21. Nc1 {In
attacking the c5 pawn, White must keep careful watch on the
opponent's dark-squared bishop, which in some cases could
become very dangerous. Thus 21. Na4 was weaker because of
21...Bf2.} Qe7 22. Nb3 Bd7 { Preventing 23.Na4, but an
unpleasent surprice awaits Black.} 23. Qg2+ Kh8 24. Qg1 $1
{#} Ne8 {24...Rab8 was more tenacious, forcing 25.Qxc5,
since 25. Nxc5 fails to 25...Rg8 After 25...Qxc5 26.Nxc5
Rb6 it would not have been so easy for White to realiz e
his material advantage.} 25. Qxc5 Nd6 26. Rc1 { Capturing
the second pawn} (26. Qxc7 { would have allowed Black to
activate his pieces by} Rfc8 27. Qa5 Bf2) 26... Be8 27. Bh3
a5 { Black makes every effort to at least complicate
matters a little.} 28. Nxa5 Bf2 29. Qxf2 Rxa5 30. Rhg1 Bg6
31. Bf1 Rb8 32. Rc2 Nf7 33. h4 Nd6 34. Bd3 Rb4 35. Rgc1 Rd4
36. Bf1 Qd8 37. Ne2 $2 {White had only a few minutes left
before the time control. In aiming to reach move 40 as soon
as possible, he makes a mistake which could have cost him
dearly.} Rda4 $2 {It is surprising that such an experienced
player as Gligoric should miss the chance to play}
(37... Rxe4 {After all, even if this sacrifice were
incorrect, it would have led to complic ations in which
White would have had to seek practical chances, since after
quiet continuations his position would be hopeless. After})
(37... Rxe4 38. fxe4 Nxe4 39. Qe1 Qxd5 {Black would have
gained a very strong attack. At the board both players
overlo oked 39...Qxd5.}) 38. Nc3 Rd4 39. b3 Qb8 40. h5 Bxh5
