The game of tournament "CZECH OPEN - 2005"

Kovalev,A (2548) - Pribyl,J (2392) [B08]

Pardubice (open A) 3d round, 2005

1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 c6 5.Nf3 Bg7 6.h3 0-0 7.a4 Nbd7
One can struggle for initiative by way of 7. ... d5!? 8.e5 Ne4.

8.a5 e5
It is more careful 8. ... Qc7.

9.dxe5 dxe5
After 9. ... Nxe5 10.Nxe5 dxe5 11.Qxd8 Rxd8 12.Bc4? White's chances in ending will be higher.

An important moment. White does not permit Black to play 10...Qe7 and thereby it brings disharmony to arrangement of rival's figures.

10...Re8 11.Bc4 Qe7
Passing in to ending promises Black a dismal fight for a draw. Somewhat earlier in one of the games Josef Pribyl tried to defend by 11...Bf8, but in this case after 12.Qd3 White kept also some advantage.

12.Qxe7 Rxe7 13.0-0 Nf8 14.Rfd1 Be6 15.Bf1 Rd7?!
In practice it was met 15. ... Nh5 or 15. ... N6d7 defending at once 'e5' pawn. The move in the game to exchange a pair of castles is hardly accessible.

May be, it were stronger 16.Nxe5! Rxd1 17.Rxd1 Nxe4 18.Nxc6 Nxc3 (after 18. ... bxc6 19.Nxe4 Bxb2 20.Nc5+ White castle is inescapable to break into Black camp) 19.Ne7+ Kh8 20.bxc3 Bxc3 21.Rb1+ and Black should give away 'b' pawn as it loses 21...Bxa5? because of 22.Bd4+?.

16...N6xd7 17.Rd1
Considering an immediate transfer of 17.Nd2, one had to count with a move 17...f5.

It is more accurate to move 17. ... h6, in order for 18.Nd2 to have possibility to counter play by means of 18...f5 19.g3 Nf6.

18.Nd2 Kf7
For 18. ... f5 it could follow 19.g3 and Black cannot play 19. ... Nf6 because of 20.Nf3+. Another plan of defence consisted in a move 18...b5, in order not to allow white knight to occupy 'c4' square.

19.Nc4 Ke7 20.Na4
White can allow not to hasten Knight's invasion to 'd6', in order after 20.Nd6; it had not to count with advance of black pawn 'b' - 20... b6 (bad is 20... b5? because of 21.Bxa7?).

20...Kd8 21.Nc5 Kc7 22.Nxe6+ Nxe6 23.b4
With exchange of the knight onto Black's white-field Bishop White's advantage acquired more real outlines.

23...Bf8 24.c3 Be7

Inconspicuous, but exclusively strong move. White prepares Bishop's transfer to 'h3' field.

25. ... b5? lost because of 26.axb6+ axb6 27.Rxd7+ Kxd7 28.Nxb6+?. In case of 25...f5 White would continue its plan by means of 26.h4+.

26.h4 b5 27.Nb2 a6 28.Nd3 c5?
It is connected with a tactical error. One should play 28...Rd8 in order to play 29... c5+ only to 29.Bh3.

29.bxc5 Ne6
29... Rd8 does not help because of 30.Nb4+-.

30.Nb4 Bxc5
30... Ndxc5 loses in view of 31.Nd5+ Kd8 32.Nb6+?.

31.Bh3 Ndf8
In case of 31...Bxe3 32.Bxe6 Nc5 33.Bd5?. Black loses a figure.

32.Nd5+ Kc6

After 33.Nxf6 Bxe3 34.fxe3 Nc5+ Black still has kept possibilities of resistance.

33...Ra7 34.Nxf6 Rf7 35.Ng4 Bd6 36.Rd5 Nd7 37.Nxe5+ Nxe5 38.Bxe6 Re7 39.Bc8 Nf3+ 40.Kg2 Rxe4 41.Kxf3 Kxd5 42.Bb7+ Kc4 43.Kxe4 Black resigned (1-0).
