1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 a6 7.Na3 Be7 8.Bg5 Be6 9.Bxf6 Bxf6 10.Nc4
The fight is around the d5 square. I would've liked to exchange the light squared bishops with Bc4, but Black doesn't take on c4. And if I take on e6, fxe6, covering d5.

10...Be7 11.Be2 0-0 12.Ne3
[12.a4 Not allowing Nd7 for now was probably better (pawn on d6 has to be defended by the queen), but i wanted to prevent f5, not that it is terribly good for black.]

12...Nd7 13.a4 Rc8 14.0-0 Nf6 15.Qd3
Preventing a possible exchange sac on c3.

15...Rc5 16.Rfd1
[16.b4 was probably better, because later it took a considerable effort to make this move. 16...Rc7 17.Ncd5 Nxd5 18.Nxd5 Bxd5 19.exd5 ]

16...Qc7 17.Ra3
With the idea of playing b4 if Black plays Rd8, preparing the d5 breakthrough.

17...Rc8 18.Bf3 Qb6 19.Rb1 Qc7
Black's activity on the c-file compensates the weakness of d5.

20.h3 h6 21.Ne2 Bc4?!
I think exchanging the bishop was a mistake, I had been planning to do that myself.

22.Qd2 Bxe2 23.Qxe2
Now if I can neutralize Back's initiative on the c-file, I have the potentially better bishop.

23...Bf8 24.c3 Qc6 25.Qd3 Ra5 26.Rba1 Rc5 27.Rc1! Qe8
[The idea of 27.Rc1 was 27...Ra5 28.Qc2 and b4 is the threat. 28...b5 29.axb5 Rxb5 30.b4 ]

28.b4
We stopped recording at this moment. The game was a roller coaster after this.

28...R5c7 29.Bd1?!
I wanted to get my bishop to the nice a2-g8 diagonal, but in doing so didn't exercise any caution. [29.Rb1 a5 30.bxa5 d5 31.Rab3 ; 29.a5 d5 30.Nxd5 Nxd5 31.exd5 Bxb4 32.Rb3 Bd6 33.Rcb1 ]

29...a5! 30.b5?
[30.Rb1 Be7 31.Bb3! the point is Black cannot take on c3 because of bishop check on f7. White's bishop is much better than Black's. 31...axb4 32.cxb4 Kf8 33.Nd5 Nxd5 34.Qxd5+/= ]

30...d5 31.Rb3 d4?
Let's White right back into the game. Why not just take the pawn on e4?

32.Nd5 Nxd5 33.exd5 Bb4
[33...e4 34.Qxd4 Bc5 35.Qd2 e3 ]

34.c4
I don't know if I remembered the moves correctly after this move , but the moves are correct again after 45.Qe4.

34...Bc5 35.Bg4 Rd8 36.Re1 Bd6 37.Rbb1 Qf8 38.Kh1 Re8 39.Re2 Bb4
Tho position looks drawn, but i started to seek adventure.

40.f4 Qd6 41.fxe5 Rxe5 42.Rc1
[42.Rd1 Rxe2 43.Bxe2 b6 44.Qxd4 Bc5 45.Qe4 Re7 46.Qf3 Re3 47.Qg4 Qe5 48.Bf1 Qb2 49.Qc8+ Kh7 ]

42...Rxe2 43.Bxe2 b6 44.Qxd4 Bc5 45.Qe4
I had probably 30 seconds left and started losing the thread of the game.

45...Re7 46.Qf3?!
giving black a tempo [46.Qg4 Qe5 47.Bd3 Bd6 48.g3 Qe3 49.Rd1 Bxg3 50.Rg1 ]

46...Re3 47.Qg4?
[47.Qf1 Was the only move. But it is hard to retreat when you are fighting for the initiaative.]

47...Qe5 48.Bf1 Qb2?
Giving White a chance to draw the game.

49.Rd1??
[49.Qc8+ Kh7 50.Qf5+ Kg8 51.Qc8+ Bf8 52.Rd1= ]

49...Qf2!
Takes control of the f5 square and prepares to mate on g1.

50.Qc8+ Kh7 51.Qg4
Diagram # Here I had about 8 seconds left and Ratko had 38. We both saw the idea of the rook sacrifice and I prevented that but the position is lost.

51...Rxh3+??
[51...f5 or as Ratko suggested after the game; 51...Re1 wins.]

52.gxh3!
the g1 square is covered, there's no mate! [52.Qxh3? Qg1# ]

52...Qc2
not even sure if this move was played in the game or in analysis, with 8 seconds on the clock one might start having visions.

53.Bd3+
Black resigned 1-0
