6th WSCC (6.1), 26.07.2010
[GM Gurevich M, FM Ali Marandi C]

Important game for the leadership from the 6th round.

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.Bd3 Nf6 6.0-0 d6 7.Qe2 Be7 8.f4 0-0 9.Kh1 e5!?
An interesting idea coming from home preparation.

[10.Nf3!? was interesting]

10...Nc6 11.Nc3 Nb4
Simply going for two bishops.

12.fxe5 dxe5 13.Bg5 Nxd3 14.cxd3
[14.Bxf6 Bxf6 15.Rad1?! (15.cxd3 Be6 Transposes to game.) 15...Nf4 16.Rxf4 (16.Rxd8 Nxe2 17.Rxf8+ Kxf8 18.Nxe2 Be6-/+ Black is better due to the bishop pair.) 16...exf4 17.Rxd8 Rxd8-/+ ]

14...Be6 15.Bxf6 Bxf6 16.Nc5 Qe7
[>=16...Qd6 17.Nxe6 fxe6 ]

17.Nxe6 fxe6!
Main idea of Black's strategy, covering d5-square and preventing White's knight from entering the center.. Despite of double pawns Black's position is promising. Next step- activation of the Bishop...

18.Nd1 Bg5 19.Nf2
[19.Ne3 Qc5 20.Nc4 b5 21.Na5 Rac8=/+ Black is better, as Na5 can not find good position.]

19...Qc5 20.Ng4 Rxf1+
[20...Rac8 21.h3 with idea Ng4-h2-f3]

21.Rxf1 h5!
Very concrete, forcing N to a passive position.

[22.h4 Bxh4 23.Nh2 g6 24.g4 was the best defencive chance-computer's idea.]

Black is activating all pieces.

23.Nh3 Rxf1+ 24.Qxf1 Be3
Nh3 is paralyzed, White is in a big trouble.

Practically loosing move. [25.Qd1 was the most resistant, prophilactical against the following activisation of the opponents Q. 25...b5 26.b3 g6=/+ Black is slightely better.]

25...Qc2 26.b3 Qxa2
All endgames lost for White now...

27.Qf3 Qb1+ 28.Kg2 Qc2+
Good technic. [28...Qxd3 29.Qxh5 Qxe4+ 30.Qf3 Qd3-+ ]

29.Kh1 Qxd3 30.Ng1
[30.Qxh5 Qxe4+-+ ]

30...g6 31.Ne2 Kg7 32.Kg2 Qd2
With idea 33...Bc5,34....Qe3 avoiding any slightest counter-play of the opponent. [32...Qxb3 33.g4 hxg4 34.Qxg4 Bf4 35.h4 Qd3-+ ]

33.h4 Bc5 34.g4 Qe3 35.g5 Qxf3+ 36.Kxf3 b5 37.Nc3 Bd4 38.Nb1 a5 39.Na3 a4 40.Nxb5
[40.b4 Bc3 41.Nc2 Bb2 ]

40...axb3 41.Na3 Kf7
Improving the king.

42.Ke2 b2 43.Nb1 Ke7 44.Nd2 Kd6 45.Kd3 Kc5 46.Kc2 Kb4 47.Kb1
[47.Nf3 Bc3 48.Kb1 Kc4 49.Kc2 b1Q+ 50.Kxb1 Kd3-+ ]

47...Kc3 48.Nf1 Kd3?!
[>=48...Bf2 Prophilactic against Nf1-g3-h5 was winning quicker.]

49.Ng3 Bf2 50.Nxh5 Bxh4
Game is over.

51.Ng7 Bxg5 52.Nxe6 Bc1 53.Nc5+ Kd4 54.Nb3+ Kxe4 55.Nxc1 bxc1Q+ 56.Kxc1 Kf3 57.Kd2 Kf2 58.Kd3 g5 59.Ke4 g4 60.Kxe5 g3
Ali Marandi gave a nice example of the Bishop's strength over the Knight. 0-1
