Round 9
Denmark

2008.07.26

1.e4 c5 2.Nc3 Nc6 3.Bb5 d6 (3... Nd4) (3... a6 4.Bxc6 dxc6 5.f4)

4.Bxc6+ bxc6 5.f4 g6 (5... c4 6.Qe2 Ba6 7.Nf3 Qb6 8.e5)

6.Nf3 Bg7 7.d3 Nh6 8.O-O c4! OLALA! ( I didn't like much 8... O-O 9.Qe1 Qb6 10.Kh1 Ng4 11.h3 Nf6 12.Qh4 Re8) (8... f5 9.e5 dxe5 10.Nxe5 Bxe5 11.fxe5 Ng4 12.Qe1 Qd4+ 13.Kh1 Qxe5 14.Qxe5 Nxe5 15.Re1 White has a slight advantage)

9.d4 (9.dxc4 Qb6+ 10.Kh1 Ba6 White has sufficient compensation for material deficit (10... Be6) 11.Qd3 Qb4 (11... Ng4 12.h3 Nf2+ 13.Rxf2 Qxf2 14.Be3 Qg3 15.Ne2) 12.Nd2 O-O with idea f7-f5.)

9... Qb6! (9... O-O probably okay, but not dynamic enough :-))

10.h3 Logical move, taking g4 under control. ( I thought that better is 10.Na4 Qa6 11.b3 O-O 12.Bb2 Ng4 13.Qd2 Bd7! White has moderate counterplay with c5 and play over b-file.)

10... d5! OLALA again! I must be dynamic and give some life to my bad pieces, mainly Nh6 now! ( I dislike computer's idea 10... f5 11.e5 O-O when Bishop remains locked ( or 11... Nf7 12.exd6 and my King might be in danger.))

11.e5?! A bit too optimistic (11.exd5 is principled but not really nice for White because it opens the position too soon. 11... Nf5 position is opened and Bishops are smiling! (11... Bb7!? also not so bad) 12.dxc6 Be6! White has sufficient compensation for material deficit with crazy position, that seems to be ok for black, for example: (12... Nxd4? 13.Be3 Nxf3+ 14.Qxf3) 13.g4 Nxd4 14.Be3 Nxf3+ 15.Qxf3 Qxb2 16.f5 Qxc3 17.fxe6 f5! 18.gxf5 O-O unclear position with olala play!)

11... Nf5 Black has a slight advantage The Knight is LALA now!

12.g4? My opponent trusted in this move, but missed small detail in his calculations... (12.Qe1! h5! black enjoys a beautiful French structure where white misses his light-squared Bishop :-) ( but not 12... Nxd4 13.Nxd4 Qxd4+ 14.Be3 losing the Queen.))

12... Ng3 13.Re1 h5! Again saying OLALA! It is time to open his kingside, revealing why I didn't castle before, just dreaming about a possible h5!

14.Kg2 (14.g5 is simply too sad... 14... h4 15.Kg2 Bf5 Black has a moderate advantage)

14... hxg4! 15.hxg4 Ne4 This was my point, and I had to foresee it before playing 10...d5, making sure that there will be something for me! Olala intuition or what?! :-))

16.Nxe4 dxe4 17.Ng5 Rh4! Only this justifies my strategy and plans! This is the move that was missed by my opponent! Now he seems to be lost, and I was hoping for a quick win, until I started calculating more carefuly and saw amazing olala lines!

18.e6 Now I thought for about 40 minutes! My earlier plan was to play f5 here! Surely black is better, but then I thought perhaps it is time to calculate a forced line, maybe there is a forced win? Eventually, I droped those lines and took up probably the best move. Intution had to be trusted, but I calculated too much...

18... Bxe6!? Ugly move but I calculated that I win by force in all lines I saw, which later proved to be much harder than compared with simple 'positional' f5! (18... f5! I knew I am clearly better, but just couldn't see a forced win, which in fact was not needed at all! :-)) 19.gxf5 gxf5 20.c3 Qc7 Black has a moderate advantage 21.Rh1 Rg4+ 22.Kf1 Qd6 23.Rh7 Kf8 24.Nxe4 Qd5 25.Nf2 Rg3 26.Qh5 Bxe6 Black has a moderate advantage) (18... f6 was the reason I thought so long! But it is a mistake!!! 19.Nxe4 Bxe6 20.Nd6+!! This is an amazing save and I was lucky to see it! (20.Nxf6+ Bxf6 21.Rxe6 Kf7! Black has a moderate advantage) 20... exd6 (20... Kd7? 21.Qe2 White has a moderate advantage) 21.Rxe6+ (21.Qe2 O-O-O 22.Qxe6+ Kb8 23.c3 f5! White has the attack (23... Qc7 24.Be3 unclear position is also alive for white...)) 21... Kd7 22.Qe1 Rah8 23.Re7+ Kd8 24.Qe6!! Hard to believe, but there is no checkmate! Only draw here! hahaha Chess is an amazing game,no?! 24... Rh2+ 25.Kf1 (25.Kg1 Qxd4+) 25... Rh1+ 26.Kg2 R8h2+ 27.Kg3 Rh3+ 28.Kg2 equal chances, quiet position)

19.Nxe6 fxe6 20.Kg3?! (20.Qe2 was the best defence! 20... Bxd4! and this is a suggestion of Rybka! Wow, I totaly underestimated this one, so not sure if I would have played it... (20... Qxd4 21.Be3 Qxb2 22.Bf2! White has a slight advantage another Rybka move! (22.Qxc4 Kf7 23.Kg3 Rah8) (22.Kg3 Rh7 23.Qxc4 Kf7 24.Rh1 Rah8 Is what I saw, but white is also alive)) (20... O-O-O 21.c3! (21.Qxe4 Rdh8 22.Qxe6+ Kb8 23.Be3 (23.c3 is computer's calm move, with totally equal position for White! 23... Qb5 was my plan, but still no win even after (23... Rh2+ 24.Kf1) 24.g5 Rh2+ 25.Kf3) 23... Bxd4 (23... Rh2+ 24.Kf3 R8h3+ 25.Ke4!! amazing position! I couldn't find a win here during the game! I was trully shocked with this line!!! 25... Rxe3+ 26.Rxe3 (26.Kxe3 Qxd4+ 27.Kf3 Rf2+ (27... Qf2+ 28.Ke4 Qxc2+ 29.Kf3 Rh3#) 28.Kg3 Qxf4+ 29.Kh3 Rh2#) (26.Rxe3) 26... Qxd4+ 27.Kf3 Rh3+ 28.Ke2 Rh2+ 29.Kf3 Rh3+ equal chances, quiet position I saw it all!!!) 24.Bxd4 Rh2+ 25.Kf3 Qxd4 26.Qe5+ Qxe5 27.Rxe5 Rxc2 I saw as my best chance, still white has drawing chances I guess... 28.f5 etc) 21... Rdh8 22.Qxe4 Rh2+ 23.Kg1 not so clear as it looks! Black pawns are weak and white looks very much alive!) 21.Qxe4 O-O-O 22.Qxe6+ Kb8 23.Qxe7 Rh2+!! 24.Kf3 (24.Kxh2 Bg1+!! Black has a decisive advantage) 24... Rf2+ 25.Kg3 Rxc2 26.Be3 Bxe3 27.Rxe3 Rxb2 28.Qe5+ Ka8 29.Rc1 black is better,but not sure about the win... 29... Rbd2 30.Qe4 (30.Rxc4 Qb1) 30... g5! Black has a moderate advantage)

20... Rh7 21.c3! Best defence! (21.Rxe4 O-O-O White has the attack 22.c3 Rdh8 23.Qf1 Qb5! Black has a moderate advantage) (21.Qe2 Bxd4! (21... Qxd4 22.Be3 Qf6 Is different 23.Rh1 still alive anyway) 22.Be3 O-O-O Black has a decisive advantage)

21... Kf7! Better than castle, since King is safer on f7 and I also want to break with c5! (21... c5! was also good probably 22.dxc5 (22.Qc2 cxd4 23.Qxe4 O-O-O! could be very interesting too! 24.Qxg6 Rdh8 25.Qxe6+ Qxe6 26.Rxe6 Rh3+ 27.Kg2 dxc3 28.bxc3 Rxc3 Black has a moderate advantage) 22... Qxc5 23.Qe2 Kf7 24.Qxe4 Qd5 25.Qxd5 exd5 26.Be3 Rah8 27.Bg1 and white is holding! I saw this only after he played c3! Now it is clear why 16...f5 was better than B:e6... 27... Rh3+ 28.Kg2 Rd3 Black has a slight advantage)

22.Rh1! And here is the best defence again! (22.Qe2 Rah8 23.Qxe4 Rh3+ 24.Kf2 c5! was my plan 25.d5 (25.dxc5 Qxc5+ 26.Be3 Qd5 27.Qxd5 exd5 Black has a moderate advantage) 25... Rh2+ 26.Kf1 (26.Kg1 Rh1+ 27.Qxh1 Rxh1+ 28.Kxh1 exd5 Black has a decisive advantage as my backup plan!) 26... Rh1+ 27.Kf2 Rxe1 28.Kxe1 exd5 29.Qxd5+ Qe6+ 30.Qxe6+ Kxe6 Black has a moderate advantage)

22... Rah8 No other choice anyway, but now I realized that white might be able to hold. (22... Rxh1 23.Qxh1 Rh8 24.Qxe4)

23.Rxh7 Rxh7 24.Qf1 (24.Qe2 Qb8! (24... c5 25.dxc5 Qxc5 26.Be3 Qc7 27.Rd1 Black has a slight advantage) (24... Qd8!) 25.Be3 (25.Qxe4 Qh8 26.Qg2 (26.f5 gxf5 27.gxf5 exf5 28.Qxf5+ Bf6 Black has a decisive advantage) 26... Rh1) 25... Qh8 26.Qg2 Here I couldn't see a clear way to win...everything looks safe for white, but in fact Rybka shows a win 26... Bf6! Black has a decisive advantage with Rh4 and R:g4! A brilliant and crushing idea! 27.g5 Rh4 28.gxf6 Qh5)

24... c5! Black has a moderate advantage OLALA again! Open up and increase the pressure before white stands up...

25.Qxc4 (25.dxc5 Qxc5 26.Bd2 e3! (26... Qb6 Is a nice computer's 'technical' move to prevent Qg1! But no real need :-)) 27.Rb1 e3 28.Be1 Qb7) 27.Qg1! Bf6! My Bishop smiles OLALA! 28.Bxe3 (28.g5 Qf5) 28... Bh4+ 29.Kf3 Qd5+ 30.Ke2 Qd3+ 31.Kf3 e5! OLALA 32.fxe5 Ke6 Black has a decisive advantage is the final OLALA touch!)

25... cxd4 26.f5 gxf5 27.gxf5 (27.gxf5 Be5+ 28.Kg4 dxc3 29.Qxe6+ Qxe6 30.fxe6+ Kxe6 31.bxc3 Bxc3 32.Rb1 Rh1 is the simplest way to win.)

27... Be5+ Black has a decisive advantage And I expected Kg4, but he resigned! Black wins anyway! :-))
