1. e4 c5 2. Nc3 Nc6
Sicilian (B23), closed, 2...Nc6



 3. a3 b6 4. Bc4 e5 
[4...Nf6 5.Nf3+/- ]

5. Qf3
White sets up for an easy win with 6.Qxf7. Needless to stay, it is noticed
[Better is: 5.Nf3!?+- ]

5...Nf6+/= 6. d3
[6.Nge2 Nd4 7.Nxd4 cxd4+/= ]
 
6...g6 
 [6...Nd4 7.Qd1 b5 8.Bxb5 Qa5+/- ]

7. Bg5 Bg7??
White wins a piece with Nd5, attacking the pinned knight a 3rd time.

[the position is going down the drain {7...Be7 8.Nge2 0-0+/-}]


8. Bxf6?
White misses the opportunity to win a piece, and takes a trade instead.
[Better is: 8.Nd5 nails it down 8...Nd4 9.Nxf6+ Bxf6 10.Qxf6 Qxf6 11.Bxf6+- ]

8... Bxf6+/=
[Black has the pair of bishops]

9. Bd5
[>=9.Nge2!?+/= has some apparent merit]
 
9...Nd4 

[Black threatens to win material: Nd4xf3]

10. Qd1 Rb8 11. Nf3 Bb7
[11...0-0 12.0-0= ]
 
12. Ba2
White chooses to retain the bishop on a strong diagonal vs trading bishops and then playing Nd5, giving the knight a strong, lasting outpost.
[Better is: 12.Bxb7!? Rxb7 13.Nxd4 cxd4 14.Nd5+/- ]


12... O-O= 13. Nxd4 exd4 14. Nd5 d6
[14...Be5!?=/+ ]
 
15. Qf3 Bxd5 
[15...Be5 16.0-0= ]
 
16. Bxd5+/=
[Opposite coloured bishops appeared. Here comes the goal-getter]


16...Qd7?? 
[16...Qe7 17.0-0+/= ]
 
17. O-O-O??
Black leaves his bishop hanging, but White had castling on his mind and missed it.
[Better is: 17.Qxf6 and the rest is a matter of technique 17...Qd8 18.Qf4+- ]

17... Kg7 18. h4 h5 19. Rdg1
[>=19.Qg3+/= ]
 
b5 20. b3??
[not a good decision, because now the opponent is right back in the game {Better is: 20.g4!? hxg4 21.Rxg4+}]

20...b4
[Black gains space {20...Qg4 21.Qxg4 hxg4 22.h5=}]

21. a4
[21.axb4 cxb4 22.g4 hxg4 23.Rxg4+- ]
 
21...a5?
[Better is: 21...Qg4= and Black can hope to survive]

22. g4 Rh8?
Black should trade pawns with hxg4, as the move played simply loses the h-pawn (or worse) because of the pin on the g-pawn.
[Better is: 22...hxg4 23.Rxg4 Qe7+- ]


23. gxh5 Rxh5??
Black doesn't realize the g-pawn is pinned and thus the rook has no guard and is hung.
[23...Qe7+- is the last straw]

24. Qxh5 Rh8 25. Qg4
[25.Qf3 seems even better 25...Rxh4 26.Rxh4 Bxh4+- ]

25...Qe8 26. Kb2
[26.h5 seems even better 26...Qd8+- ]

26...Qe5 27. f4
[27.h5 Kf8 28.hxg6 Rxh1 29.gxf7 Rxg1 30.Qc8+ Kg7 31.f8Q+ Kg6 32.Qh3 Bh4 33.Qxh4 Rb1+ 34.Kxb1 Qh5 35.Qff6+ Kh7 36.Qxh5# ]
 
27...Qe8 28. f5
[28.h5 might be the shorter path 28...Rh6 29.Qf5 Qe7+- ]
 
28...Qc8???
Removes an important defender of the g-pawn that allows White to win that pawn and set up a devastating attack on the king.


29. h5?? 
White loses the opportunity to win the g-pawn, and allows black to lock up the position on the kingside.  White still retains a significant material advantage, but the position is much tougher to crack now.

29... g5! 
Locks up the pawn structure and thus makes life harder for White.  Drawing chances have increased considerably...


30. Qh3 
[30.h6+ makes it even easier for White 30...Kf8+- ]

30...Kh6?
Hangs the f-pawn.
31. Bxf7 Rh7 32. Be6
[32.Bg6 keeps an even firmer grip 32...Rh8+- ]

32...Qf8 33. Rg4 Rg7 34. Rhg1 Qe7
Having locked up his side, Black starts the process of waiting.



35. Qh2 Qf8 36. Qd2 Qe7 37. Qc1 Qf8 38. Rxg5?? [!]?
White tries to break open the position, but this move just loses a rook.
[Mate threat]?


38... Bxg5 
[38...Bxg5 39.Qf1 Combination; 38...Rxg5 39.Qf4 Combination; With the idea: 38...-- 39.Rg6+ Mate threat]

39. Rxg5??
Loses the exchange.  This series of exchanges changed the evaluation from a winning position for white, to a nearly equal position.
[Better is: 39.Qd1+- secures the point]

40... Rxg5 40. Qf1??
[White lets it slip away {Better is: 40.Qf4!?+- }]

40...Kg7  
[40...Qe7!?+/= ] 

41. Qh3 Kh6 42. Qh4 Rxh5 43. Qf4+
White can salvage a draw with perpetual checks by his queen.
(There was a win for White even after 43.Rg5....but it took over 40 moves for a computer to find)


43...Rg5 44. Qxd6???
White simply gives the queen (and the game) away...

[an unfortunate move that relinquishes the win {44.f6+/- }]


44...Qxd6+
White Resigns
0-1
