(1) Macieja,Bartlomiej (2606) - Radjabov,Teimour (2742) [C63]
FIDE World Cup 2007 Khanty-Mansiysk (2.1), 27.11.2007
[Efstratios Grivas]

1.e4 e5 2.Nf3 Nc6 3.Bb5 f5
The not often played 'Jaenisch Variation' of the 'Ruy Lopez', probably prepared by Radjabov before-hand especially for this event.

[4.Nc3 is considered to be the main line but things are not so clear-cut anyway and I am pretty sure that Radjabov would have come up with some fresh ideas.]

4...fxe4 5.dxe4 Nf6 6.0-0 Bc5
[Unpleased for Black is 6...Nxe4?! 7.Re1 Nf6 (7...d5 8.Nxe5 Bc5 9.Qh5++- (9.Rf1? Qd6~~ Pirklova,H-Havrdova,L/Svetla nad Sazavou 1994) ) 8.Bxc6! (8.Nxe5 Nxe5 9.Rxe5+ Be7 10.Qe2+/= ) 8...bxc6 9.Nxe5 Be7 10.Qe2 Bb7 11.Bg5+/- .]

7.Bxc6 bxc6 8.Nxe5 0-0 9.Bg5
[Other white options are 9.Nc3 ; and 9.Qe2 .]

[The most principled continuation. Of course Black's 'possibilities' includes 9...d6 10.Nd3 (10.Nxc6?! Qe8 ) 10...Bb6 11.Nd2 (11.Nc3 Ba6 12.Kh1 Qe8 Van Blitterswijk,S-Hendriks,R/Dieren 2004) 11...Qe8 12.Bxf6 Rxf6 Gurevich,V-Jonkman,H/Cappelle la Grande 1994; or 9...Ba6 10.Nd3 Qe7 (10...Be7 11.Nd2 Nxe4 12.Bxe7 Qxe7 13.Nxe4 Qxe4 14.Nc5 Qc4 15.Nxa6 Qxa6 16.Qxd7 Qb6 17.b3 Rad8 18.Qe6+ Kh8 19.Qe3+/- Sisniega,M-Burke,J/New York 1984) 11.Nd2 Bd4 12.Nb3! (12.Nf3 Qxe4 13.Re1 Qf5~~ Aginian,N-Dimovska,A/Dresden 2004) 12...Bb6 13.e5 Bxd3 14.exf6 gxf6 15.Qxd3 fxg5 16.c4+/= .]

[Somewhat naive would be 10.Nd3?! Nxe4 11.Nxc5 Nxg5=/+ .]

10...Rxf6 11.Nd3 Bd4!
[11...Bb6 would transpose to the 9...d6 comments.]

[Black achieves enough compensation after 12.Nd2 d6 13.Qe2 Qg6 14.Kh1 Ba6 15.Rab1 Raf8 due to his bishop-pair and his active pieces, as in Spassky,B-Antunes,A/Thessaloniki 1988.]

12...Bb6 13.Nd2 d6
[13...Ba6 is interesting: 14.c4 (14.e5 Rf8 15.c4 Qg6 16.Qe2 d5 17.Nb4 Bc8 18.cxd5 Bh3 19.g3 Bxf1 20.Rxf1~~ 1/2-1/2 Schaefer,M-Micic,J/Dortmund 1991) 14...Rh6 (14...d5?! 15.Qa4!+/- Shinkevich,V-Geller,J/Vladimir 2002; 14...Rd6 15.Qb3 Bd4 16.c5+ Re6 17.Nf4 Bxf1 18.Nxe6 Qxe6 19.Qxe6+ dxe6 20.Kxf1 Bxb2 21.Rb1+/= ) 15.Qb3 Bd4 16.Nf3 c5 .]

[Not much is offered by 14.Qe2 Qg6! (14...Ba6 15.c4 Qf7 16.b3+/= Bruzon Bautista,L-Gomez,F/Santa Clara 2000) 15.Kh1 Bg4 16.f3 Be6 .]

[A new move but not a satisfactory one in my opinion. 14...Rh6 15.Re1 (15.c5 Bxc5 16.Nxc5 Qe5 17.Nf3 Qxc5 ) 15...Qe7 16.Nf1 Qg5 17.Qd2 Qh5 was seen in Aginian,N-Shukurova,M/Elista 1998.]

[A useful defencive move. Bad is 15.c5? Bh3 16.Qb3+ Kh8 17.Nf4 Rxf4 18.Qxh3 Bxc5-/+ .]

15...Bg4 16.f3 Be6 17.f4
[Although the text-move is fine too, 17.c5! looks to be quite strong: 17...dxc5 (17...Bxc5 18.Nxc5 dxc5 19.f4+/- ) 18.f4 c4 19.Ne5 Qe8 20.Qc2+/- .]

17...Bg4 18.Qe1 Re8 19.c5!
The thematic advance which allows White to gain the advantage.

[19...dxc5 20.Ne5 Qh5 21.Nxg4 Qxg4 22.h3+/- .]

20.Nxc5 dxc5 21.h3 Bc8
[21...Qh5 22.Qe3 c4 23.Rae1+/- .]

22.Qe3 Qh6 23.Rf3 Rd8 24.Nc4
White has gained a clear and long-term advantage. The material in quantity terms is equal but just compare the white e- and f-pawns to the black c5- and c6-pawns. Then it is easy to understand that quality counts.

24...Rd4 25.b3 Qh4 26.Raf1 Rf8
[26...Ba6 27.e5 Rf8 28.e6+/- .]

27.Ne5 Qf6 28.Rc1 Qd6 29.Nxc6!
A small combination that wins material.

[29...Qxc6 30.Qxd4 cxd4 31.Rxc6 Bb7 32.Re6 .]

30.Rxd1 Qxd1+ 31.Kh2 Qd6 32.Ne5
[Also possible was 32.Nxa7 Ba6 33.a4 Qb6 34.Nb5 Bxb5 35.axb5 Qxb5 36.e5+- .]

32...Bb7 33.Nd3 c4 34.bxc4 Re8 35.Ne5
Game is over and the rest was not really too interesting (although a bit of precision is needed of course!).

35...c5 36.Rf2 Rd8 37.Rb2 Ba8 38.Nf3 Rf8 39.e5 Qe6 40.Qxc5 Qf5
[40...Bxf3 41.gxf3 Qf5 42.Qd5+ Kh8 43.Qe4 Qd7 44.f5+- .]

41.Qe3 Be4 42.c5 Bd5 43.Rd2 Ba8 44.Nd4! Qxf4+ 45.Qxf4 Rxf4 46.Ne6 Rc4 47.Ng5
[47.Rf2! was better but anyway Black was obliged to resign as after 47...Rf4 48.e6 there is no salvation.] 1-0
