 [#]14...b5 15.¥b3 a5 16.a4 ¥a6 17.£e1 ba 18.¤a4 ¥b5 19.¤c5!? Grishchuk starts playing on that flank, where Black usually displays activity. Perhaps, 19.h4 would have been a more logical choice for White. 19...a4! 20.£b4 ab 21.c4! [So far, the white knight cannot move deeper into Black's camp: 21.¤e6 £d5! 22.¤f8 £e4! 23.£b3 ¦a1 24.¢d2 £e2 25.¢c3 ¦d1 , and Black wins; after 21.£b3 ¥e2 22.¦e1 ¥f3 23.gf fe 24.¤e6 £a5 , Black also obtains a sufficient counterplay.] [After 21...¦a1? 22.¢d2 ¦d1 23.¢d1 , Black loses his b5-bishop.] [After 22.¤e6 £b8 23.£e7? ¤f5 black pieces improve their positions swiftly.] [Again 23.¤e6 would have been beneficial to Black: 23...¥h6 24.¢b1 £c8! 25.¤f8 ¤e3! (£f5 threatened) 26.¤g6 hg 27.¤h4 ¥c4] 23...¥h6 24.¢b1 ¤e3 Menwhile, the black knight does it in one go! 25.¦e3 ¥e3 26.£b3 ¥h6 27.£b4!? White prevents the black queen's activation by £a5. 27...¦a7 Black admits deploying his queen to the most passive position on a8 in order to retain control over the a-file. 28.e6! [Yet again 28.¤e6 is bad for White: 28...£c8 , and he cannot capture the black f8-rook due to the black queen's check from f5.] 28...£a8 29.¢c2 ¥c8 30.¦d3 [Deserving attention was the prophylactic continuation 31.¤d2 g4 32.h4] 31...g4! 32.hg ¦g8 As the black rook gets out of the cage, Grishchuk constructs a new one for it: 33.¥c7! [33.¥b8? , with the same idea, fails to 33...¦a3 34.ba ¥e6!] [Much more dangerous for Black is 35.£a3 £a3 36.ba , and Black must take some sophisticated measures fighting the white a-pawn: 36...¥e3! 37.¢d3 ¥c1!? (or 37...¥f2 38.¤e4 ¦e4 39.¢e4 ¥e6 =) 38.a4 ¥a3 39.¤d7! ¥b4 40.a5 h5 , with the dynamical equilibrium.] [36...¥f2!? with the idea of 37.a4 ¥g3 38.£b6 ¥e6! 39.¤e6 £a4] [Instead, White should have exchanged the queens by 38.£b8 £b8 39.¥b8 ¥a3] 38...¥a3! 39.£b3 £a8 40.¤e4 c5? An attractive but wrong continuation. [After 40...¥e6 41.¥f4 ¥d6 42.¤d6 ed 43.¥d6 Black obtains the extra exchange and perfect winning chances.] 41.¥f4! White avoids the following trap: [41.d5? ¥a6! (with the threat of £xd5) 42.¢e3 ¥c1 43.¤fd2 ¥c4! 44.£c4 ¥d2 45.¢d2 £b8] 41...¥c1 42.d5 This leaves the black light squared bishop locked. 42...¥f4 43.gf ¦f4 44.¢e3 ¦g4 45.£b6! ¥a6 [Dangerous for Black is 45...£a4? 46.£d8 ¦g8 47.£e7 £a3 48.¢f4 £c1 49.¤fd2!] [Correct is 46...£b8! 47.£e7 £f4 48.¢f2 £e4 49.£f6 ¦g7 , and White must settle down with the perpetual check.] [The sudden 48.£d4!! would have brought a win for White, so far as 48...¢g8? (better is 48...¦g7 49.d6 ed 50.¤d6 , but Black's position is suspicious in that case too) runs into 49.d6! ¦e4 50.¤e4 fe 51.d7 £b3 52.¢f2!? £f3 53.¢e1 £g3 54.¢d2 , and the white d-pawn promotes inevitably.] 48...¦g6 49.¤d3 ¦g3 50.¢e2 ¦g4 [Better is 50...¦g2 51.¢d1 £b8 52.£e7 ¥c4! , and White must force the perpetual check on the f6 and f7-squares.] [White could have tortured his opponent more with 51.¤b4] 51...¥c4 52.¤c4 ¦c4 53.£f5 £b8 54.d6 ¦c2 55.¢f3 £a8 56.¢e3 £a7 57.¢f4!? £a4 58.¢g3 The white king seems to avoid the checks, White threatens with the checkmate in one move and one of the white pawns is about promoting. However, Black finds a surprising move 58...£a8! Black's pieces meet in the g2-point after having experienced an apparent lack of coordination. White is just one tempo short. 59.£e5 ¢g8 60.£g5 ¢h8 61.£e5 ¢g8 Draw. [1/2:1/2] |
