He wants to take me out of book, eh? Well, take ...
7. Nde2 Be6 8. Bg2 Nbd7 9. O-O b5 10. a3 Nb6
Black seems to have a nice position, with a firm control of d5 - which is what matters in similar positions. However in the next few moves I start wandering around with my queen instead of completing development (Be7, 0-0, Rc8)
11. f4 Qc8 12. Kh1 Be7 13. b3 Qc5? 14. Qd3 O-O
I intended to play here 14...Ng4, but alas white has the simple 15.Qf3 with advantage.
15. Be3 Qc7 16. h3 Rfd8 17. f5 Bc8
As a result of black's inaccuracies white stands better. But the kingside storm plan is probably a bit too ambitious ?
18. g4 Bb7 19. g5 Nfd7 20. Nd5
A logical continuation would have been 20.f6. Since white refrains from this move, black can organize his defense.
20... Nxd5 21. exd5 f6 22. h4 Rac8 23. c3 Nc5
Suddenly black has the initiative!
24. Qd1 a5 25. Rb1 a4
But this is too hasty. Black is overlooking something...
26. Bxc5 dxc5 27. bxa4 bxa4 28. Qxa4
Only now did I notice that after 28...Bxd5 29.Bxd5 Rxd5 the pin 30.Qc4 is very unpleasant for black. So I try to prevent this, but allow white another tactical shot. Fritz recommends 28...Rd6, intending to capture on g5 or d5 later.
28... c4?? 29. Rxb7! Qxb7 30. d6
Now black is almost lost! I try one last chance - a passed pawn on b3.
30... Qb3 31. Qxb3 cxb3 32. dxe7 Rd2 33. Bf3?
White returns the favor with a mistake of his own. After 33.Ng3 white should win.
33... Kf7 34. Rb1 b2 35. Kg1 e4
This is the punishment for the unsuccessful move 33.Bf3 ...
36. g6+ hxg6 37. fxg6+ Kxe7 38. Bg4 Ra8!
The rook penetrates to a1 and white must lose some material.
So far so good, but instead of this move, black could have won with 43...Kd6 - preventing the entrapement of the black king as happened in the game. b1=Q could have been played on the next move as well ...
44. Bxb1 Rxb1 45. Nd4!
White finds the only way to achieve a drawish position.
45... Rc1 46. Nf5+ Kf8 47. Kg3?? Rxc3+??
A small comedy of errors in mutual time-trouble: white should have played 47.Kf3. After his mistake, black could have tipped the scales in his favour with 47...Rg1+ and 48...Rxg6
48. Kg4 Rc4+ 49. Kg3 Rc7 50. h5 Rd7 51. Kg4
Ok, so now g7 is defended, and I intended to win by walking my king around the rook - Kf8-e8-d8-c7-etc. - but noticed in time that if the king goes to far away to the queenside, white plays Nxg7! Rxg7 Kf5 - and he actually wins! So now I realised I cannot win this endgame - unless my opponent helps out. He had about 3 minutes here, I had 5, so I decided to wait for his mistake.
51... Rd5 52. Kf4 Re5 53. Ng3??
And here it comes! I saw no way to win, had he just kept moving his king around.
But now the knight is stuck on g3, to defend h5, and black's king is released from his jail! Black is winning. This game has been one heck of a roller-coaster, but now it's coming to an end. Although I have little time on my clock, my technique is good enough.
24 ( +1 | -1 ) I enjoyed!zdak, continue please (posting games)! --- And just my two cents: 10. a3 Maybe, White was afraid of further advance of black b pawn. But 10. b4 doesn't any harm to white. My opinion, better was to advance the pawn in another side, I mean 10. h3
