MOST EXCITING GAME OF THE MATCH
Naiditsch,Arkadij (2674) - Nybäck,Tomi (2635) [C84]
BL 1011 Baden-Baden - Werder Bremen, 09.04.2011 [T. Nybäck / C.D. Meyer]
1.e4 e5 2.Nf3 Nc6 3.Bb5
I played against Arkadij, also with Black, in Wijk aan Zee 2010. That game went 3..f5, and I actually got quite a nice position out of the opening, but I was fairly certain he would have something better prepared this time.
3...a6 4.Ba4 Nf6 5.0-0 Be7 6.d3
A sideline, the main move is 6.Re1. I suppose his main reason for playing this was practical: In addition to playing the Jaenisch Gambit, I have played like five different systems in the main line of the Ruy Lopez, all of which need some amount of preparation. Of course I may be wrong, and he had other reasons for this move.
6...b5 7.Bb3 d6 8.a4 Bg4 9.c3 Na5 10.Ba2 c5 11.Na3N
A surprise to me, and according to my database a novelty, after which I was out of book. I mainly expected 11.h3 after which Black can choose between taking on f3 and going for some queenside counterplay with c4 or b4, or two bishop retreats: to d7 as in the game, or 12..Be6!?.
11...Bd7!?
A bit strange move, moving the bishop back without White even playing h3. However, I felt that other ways of protecting b5 also had their drawbacks, and after the pawn is safely protected White's knight on a3 may turn out to be misplaced.
12.d4
My opponent suggested after the game that White could try something like 12.axb5 axb5 13.b4 Nc6 14.Nc2 with an advantage, but I'm not so sure.
12...exd4 13.cxd4 c4!
The most ambitious, and very interesting way of playing this position. Black hopes to get a queenside majority, and prove that White's knight and bishop on queenside are misplaced. This all is fairly risky though, as Black hasn't castled yet.
14.e5
Principal move, White needs to act fast to highlight negative sides of Black's last move.
14...Ne4
Here 14.. Nd5 was probably more solid, but I hadn't seen White's idea with Qe1 yet, and hoped to push d5 and secure a nice knight in the center of board.
15.d5!
This prevents Black from playing d5, and in case of castling he sometimes has to worry about ideas with an e6 push.
CDM: 15.d5?!; 15.exd6!? Nxd6 16.Ne5, unclear
15...dxe5?
Here castling, without fearing any ghosts, certainly was preferable. The game move helps White to develop his knight on a good square and subjects Black to a very nasty tactical idea.
CDM: Better looks 15...0-0 16.axb5 axb5 17.e6 fxe6 18.dxe6 Be8=+ [19.Bb1 (19.Nd4?! b4 20.Bb1 Nxf2) 19...Nc5 (19...d5) ]
16.Nxe5
16...Bxa3
Here I noticed to my horror that in case of my intended castling, White wins a piece by capturing d7 and forking the knights with Qe1. I thought for quite a while to get any sort of playable position, and while Black's position after the game move remains bad, at least I have some practical chances.
CDM: 16...Lxa3?; a silicon friend definitely prefers 16...0-0!!, e.g. 17.Nxd7 Qxd7 18.Qe1 Rfe8! This move but with quite a different point will be also seen later in the game. 19.Qxa5 Bd8 20.Qe1 (20.Qb4 Be7 21.Qa5 (21.Qe1 Bc5! is similar to 20.Qe1 Bb6!) 21...Bd8 22.Qb4 Be7 23.Qa5 Bd8= with repetition of the position) 20...Bb6! 21.Be3 (21.Qd1?! Nxf2! 22.Qf3 (22.Rxf2?? Qf5) 22...Re5! (22...Qxd5 23.Qxd5 Nh3+ 24.Kh1 Nf2+ 25.Kg1 Nh3+=) 23.Bb1 (23.Bf4? Rf5) 23...Rae8 24.Bf4 Re2) 21...Nxf2! 22.Bxb6 Rxe1 23.Raxe1 Nd3 24.Re2 Qxd5÷ and in this still complicated position the material is approximately balanced.
17.bxa3 0-0 18.Nxd7 Re8!
The point. After this move Black will actually not lose a piece, as the knight is trapped, but he stands worse nevertheless.
19.Qg4!
CDM: 19.axb5!? axb5 (19...Qxd7 20.b6! Nc3 21.Qd2 Ne2+ 22.Kh1±) 20.Qg4 h5 21.Qh3 Ra7 22.Nb6! Qxb6 23.Be3 Nc5 24.Qxh5± (24.Bd4±)
19...h5! 20.Qh3 Ra7 21.Be3?!
During the game I was very relieved to see this move. I had seen at this point that I'm going to lose material anyway, but it seemed to me that 21.Nb6 is much more nasty. After 21..Qxb6 22.Be3 Black cannot really give the exchange as he will just get the game position without the h5 pawn, but 22.. Nc5 23.Qxh5 also looks quite bad for Black as he has a weakened king, lots of pinned pieces and is a pawn down.
CDM: 21.Nb6! Qxb6 22.Be3 Nc5 23.Qxh5 Qd6 24.axb5 axb5 25.Bd4 Raa8 26.Rae1 Rxe1 27.Rxe1 Nd3 28.Qg4 f6 29.Re3!± Qxa3? 30.Qe6+ Kf8 31.h4 planning Bxf6+-
21...Rxd7 22.Bb6 Qxb6 23.Qxd7 Nf6
I felt that Black has reasonable practical chances here, as White's bishop at the moment is not exactly the pride of his position, and there is a good chance that he will lose his d5-pawn in the near future.
24.Qf5 g6 25.Qf3 Re5
CDM: 25...bxa4 26.Rad1 Qb2 (26...Rd8 27.Rfe1 Qd6 28.Bb1) 27.d6 Kg7 28.Bb1±
26.Rad1
CDM: Here 26.axb5! was strong: 26...axb5 (26...Nxd5 27.bxa6 Qxa6 28.Rac1) 27.d6!+- Kg7 (27...Nd7 28.Rae1) 28.Qc3 Nc6 29.Rae1
26...Rf5 27.Qg3 Rxd5
CDM: 27...Nxd5!? , e.g. 28.Bb1 h4 29.Qxh4 Rh5 30.Qg3 Qf6 31.axb5 axb5 32.Be4 Nf4 33.Qe3 ...g3±
28.Rxd5 Nxd5
My evaluation of position was rather too optimistic however, as here White gets a strong, probably winning position with 29.axb5 axb5 30.Qe5! and White's queen is centralized, and the black pawns weak. However..
29.Rd1? Qf6!
After this Black's completely back in business! It turns out that White's last move not only wasted an important tempo, but makes the threat of a knight's landing on c3 all the stronger. It's noteworthy that already for a long time White had the choice of exchanging on b5, and he probably should have done so at some point.
30.h4??
CDM: Tomi's last evaluation seems overoptimistic.
I Here White should refrain from taking on b5: 30.axb5? axb5 31.Bb1 Nc3 32.Re1 (32.Qd6?? Qxd6 33.Rxd6 Nxb1 34.Ra6 c3-+ (34...Nb3-+) ) 32...Nb3, unclear
II But 30.Bb1! Nc3 31.Qd6! still holds White's advantage: 31...Qxd6 (31...Kg7 32.Qxf6+ Kxf6 33.Rd6+ Ke5 34.Rxa6 Nxb1 35.Rxa5 Nd2 36.axb5!) 32.Rxd6 Nxa4 (32...Nxb1?? 33.Rxa6!) 33.Rxa6 Nb3 34.Bc2 Kf8 35.Kf1±
30...Nc3
CDM: With his last blunder White has lost his advantage and only now Black is really back in business.
31.Qb8+
CDM: With 31.Qb8+? White has completely ruined his position; instead 31.Rd6 was asked for, e.g. 31...Ne2+ 32.Kh2 Qe7 33.Rxg6+ fxg6 34.Qxg6+ Kf8 35.Qh6+ Ke8 36.Qxh5+ Kd8 37.axb5 axb5 38.g3, unclear/=
31...Kg7 32.Rd2 Nc6 33.Qe8
Here I realized that I am probably not going to create any serious threats against the white king anyway, as I intended to do with some Nd4, and the free pawn started to seem all the more yummy...
Both players were also in some time trouble here.
CDM: If 33.Qd6 then 33...Qxd6 34.Rxd6 Nd4!-+, e.g. 35.axb5 axb5 36.a4 Nxa2 37.Rxd4 c3 38.axb5 c2 39.Rc4 c1Q+ 40.Rxc1 Nxc1 41.b6 Ne2+ (necessary!) 42.Kh2 Nd4 and wins.
33...Nxa4 34.Bb1 Nc3 35.Bc2
CDM: 35.Be4 Nd4 36.Kf1 Ne6-+, e.g. 37.Bf3 Nb1 38.Rd1 c3 (38...Nxa3) 39.Rxb1 c2 40.Re1 Qc3 41.Qc6 Nc5 42.g3 Qxe1+ 43.Kxe1 c1Q+ 44.Ke2 Qxa3
35...Nd4
CDM: 35...a5!
36.Qe3 Nxc2 37.Rxc2 Nd5
38.Qe4?
CDM: 38.Qd2 Nf4 39.g3 Nd3 with black advantage
38...Nf4?
38.. Qa1+ 39.Kh1 Nf6! looks crushing. It's hard to believe that White can survive the threats to his king connected with Ng4+, and the eventual advance of Black's pawns. After the game move Black wants to put his knight on the solid square d3, but there is a clear negative side to this: the c-pawn won't be able to move.
39.g3 Nd3 40.Re2 Qd6 41.Qe7 Qd4
If Black wants to exchange queens, he shouldn't do it on e7, as in this endgame the white rook will be well placed on the seventh rank.
42.Re3
CDM: 42.Re3?; necessary was 42.Qe3
42...Qd5?
Simply 42.. c3 was strong. For some reason I was worried about 43.Rf3 Ne5 44.Qf6+, but actually White has absolutely no threats there and Black's pawn is simply running.
CDM: 42...c3! 43.Qc7 a5 44.Rf3 c2! 45.Qxc2 a) 45.Qxf7+ Kh6 46.Rf6 (46.Qf8+ Qg7) 46...c1Q+ 47.Kh2 Qxf6 48.Qxf6 Qb2 49.Qf8+ Kh7 50.Qe7+ Qg7-+; b) 45.Rxf7+ Kg8-+; 45...Ne1 46.Rxf7+ (46.Qe2 Nxf3+ 47.Qxf3 b4-+) 46...Kxf7 47.Qc7+ Kg8 48.Qb8+ Kh7 49.Qc7+ Qg7-+
43.Qg5?
CDM: 43.Qc7! and e.g. 43...Qf5 44.f4 offers tough resistance.
43...Qc6?
There were two winning alternatives:
I 43...Qxg5 44.hxg5 a5 45.Kf1 b4 46.axb4 axb4 47.Ke2 b3 48.Kd2 Nb4!-+ intending to play Na2 and to push the pawns
II 43...Qd4 44.Qe7 c3 etc. -+ as before
44.Qd8!
Now I noticed to my horror that White intends Re8 with some unpleasantness to my king, and decided to swap queens anyway, but in a much worse version than in the previous move. It was still possible to play 44.. Qc5, pinning the rook and retaining some advantage.
44...Qf6? 45.Qxf6+ Kxf6
In this endgame I'd probably rather have my king even on g7 than f6, as in many lines I will push my queenside pawns and White will have to bring his king closer to stop them, when I could take f2, if it wasn't for Rf3+...
During the game I thought this endgame still offers good winning chances for me, but actually it's not even clear if I'm still better here.
46.Kf1 a5 47.Ke2 Ne5 48.Re4 Kf5 49.Rd4
CDM: 49.Rd4?; 49.Ke3 c3 50.Kd4 Nc6+ 51.Kd3 (51.Kd5 Kf6) 51...Ne5+ 52.Kd4=
49...Ke6
CDM: still with black advantage
50.Kd1 Nc6 51.Rf4
CDM: 51.Rd2!?
51...Ne7
CDM: With 51...Ne7? Black throws away his last winning ticket; correct was 51...c3 52.Kc2 b4 53.axb4 axb4 with the plan f5, Kd5 etc. -+.
52.Re4+ Kd6 53.a4
CDM: 53.a4!=
53...Nd5 54.Kc2 f5 55.Re8
55...Nc7?
I It was probably time to limit the damage with something like 55.. Kc5, but Black already has to be careful not to lose. With the game move I wanted to stop Ra8, keep my queenside pawns and eventually queen one, but this seems too ambitious.
II CDM: Instead of this fateful knight move to c7 - we'll see it again - Black should advance his b-pawn first: 55...b4 56.Ra8 Ne7 (or 56...Nc3 57.Rxa5 Ne2 plan Nd4+ plus c3 =) 57.Rxa5 Nc6 58.Ra6 Kc7 59.a5 Nd4+ 60.Kb1 c3 61.Rb6 b3 62.Rb4 c2+ 63.Kb2 Ne2 64.Rc4+ Kb7 65.Kxb3 c1Q 66.Rxc1 Nxc1+ 67.Kc2 Ne2 68.Kd3 Ng1 69.Ke3 Ka6 70.Kf4 Nh3+ 71.Ke5 Nxf2 72.Kf6 Ne4+ 73.Kxg6 Nxg3 74.Kg5 Kxa5 75.Kf4=
56.Rd8+ Ke7 57.Rd4 Ne6 58.Rd5
CDM: Exposes the rook to a knight's attack. More precise was 58.Rd1!, e.g. 58...b4 59.Rd5 f4 60.Kb1 c3 61.Rxa5 Nd4 (61...Kd6 62.Rb5) 62.Rd5+-
58...b4
CDM: 58...Nc7 59.Re5+ Kd6 60.f4 b4 61.Rxa5 Ne6 62.Ra6+ Kd5 63.Rb6 Nd4+ 64.Kb1 Kc5 65.Rb7 c3 66.Rc7+ Kd5 67.a5 Nb5 68.Rb7 Kc6 69.a6 Nc7 70.Rxb4+-
59.f4
Fixing Black's kingside pawns and stopping any pawn breakthrough there. At this point I was already starting to feel that I might have managed to even lose such a position, but wasn't ready to believe it yet.
CDM: 59.f4? is not the last mistake in this most exciting game, here it comes from a stereotyped way of thinking which could easily happen to everyone.
CDM:
I 59.Rxa5? is premature in view to 59...Nd4+ , e.g. 60.Kb1 Kd6 and Black's activities are sufficient 61.Ra6+ Kc7! (61...Kd5? 62.Rb6) 62.a5 c3 63.Rb6 b3 64.Rb4 c2+ 65.Kb2 Ne2= followed by a forced exchange to a drawn pawn ending.
II 59.Kb1! (also 59.Kc1!) was asked for: 59...c3 (59...f4 60.Rxa5; 59...Nc7 60.Rxa5; 59...b3 60.Kb2) 60.Rxa5+- ( 60...Nd4 61.Rd5 )
59...c3 60.Kd3
60...Nc7?
Now 60.. g5!! was a good last trick to try in time trouble. It seems that Black would have some drawing chances, as he will manage to weaken White's kingside pawns. 60.fxg5 is met by f4 and 60.hxg5 by h4, in both cases with annoying check on f4 to worry about.
CDM: 60...g5!! not only draws convincingly but also makes demands on White, e.g.: 61.Rxa5 a) 61.hxg5?? h4-+; b) 61.fxg5? f4 62.Rxa5 f3! 63.Rf5 (63.Ra7+ Kf8! 64.Ra5 Nd4! 65.Kxd4 c2 66.Rf5+ Kg7-+) 63...c2 64.Kd2 Nd4 65.Rxf3 (65.Rd5 f2) 65...Nxf3+ 66.Kxc2 Nd4+-+ with the plan to capture the a-pawn with the king and stop the g-pawn with the knight - zugzwang takes care of the rest: 67.Kb2 Nc6 68.Kb3 Kd6 69.Kc4 (69.a5 Nxa5+) 69...Ke5 70.Kb3 Kd5 71.Kc2 Kc5 72.g6 Kb6 73.g7 Ne7 74.Kb2 Ka5 75.Kb3 Ng8; c) 61.Rxf5 gxh4 62.gxh4 Kd6 63.Rxa5 Nxf4+ 64.Kc2 Ne6=; 61...gxf4 62.gxf4 Nxf4+ 63.Kc2 Ne6 64.Rd5 f4 65.Rd1 f3 66.a5 f2 67.Rf1 Kd7 68.Rxf2 Nd4+ 69.Kd3 c2 70.Rxc2 again exchanging to a drawn pawn ending 70...Nxc2 71.Kxc2 Kc6 72.Kb3 Kb5 73.a6 Kxa6 74.Kxb4=.
61.Rxa5+- Kd6 62.Re5 Ne6 63.Rb5 Nc5+ 64.Kc2 Nxa4 65.Rxb4 Nc5 66.Kxc3 Kd5 67.Rb5 Kc6 68.Rb8 Kd5 69.Rb5
I was hoping for 69.Rg8 Ke4 70.Rxg6 Kf3 with some activity, although in fact White is easily winning here as well.
69...Kc6 70.Ra5
It was time to face reality, and try to forget about this painful game, so Black resigned. This clinched Werder Bremen's match loss, although even a win would only have been enough for a 4:4, which considering the situation in the league wasn't really good enough.
CATASTROPHE IN THE GRÜNFELD INDIAN
Nybäck,Tomi (2635) - Mann,Christian (2444) [D85]
BL 1011 Werder Bremen - SC Eppingen, 10.04.2011 [Tomi Nybäck]
1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Nf3
I have played 7.Bg5 here quite a lot lately, including several nice wins, but I had suffered a painful loss with that line in European championships just a week before this game. I felt that it was time to try something different, especially as my opponent had played the line that arises in game before, which seemed bit dubious to me.
7...c5 8.Be3
8...Nc6?!
In my opinion this is inaccurate move order, which gives White interesting additional option compared to the main lines.
9.Rc1!
Instead 9.Qd2 Qa5 transposes to main line of this system, which is fairly playable for Black, of course.
9...cxd4
9.. Qa5 10.d5! is also better for White, as 10..Bxc3+ doesn't really work in view of 11.Rxc3 Qxc3+ 12.Bd2 and two minor pieces are clearly stronger than Black's rook and pawns.
10.cxd4 Qa5+ 11.Bd2!
This is the option White didn't have in other line, where his queen was already on d2. Instead 11.Qd2 transposes to main line, and leads to an ending that gives White some chances for advantage.
11...Qxa2 12.d5
The first point. Black will now lose his castling rights after bishop check on b5, and this with development advantage gives White more than enough compensation for the pawn.
12...Na5?
Here 12..Ne5 was the only way to play, and after 13.Nxe5 Bxe5 14.Bb5+ White has an initiative for the pawn, but Black's position looks playable.
13.Bb5+ Bd7
13.. Kf8 looks too ugly to be played, but the game move loses more or less directly.
14.Rc2! Qa3 15.Qb1!
The second point: White now has a multitude of threats, like taking on d7 and Qb5+, and in many lines also Ra2.
15...Qb3
The only try, but insufficient.
16.Bxd7+ Kxd7 17.0-0!
I was surprised to hear many teammates suggest 17.Rc7+ here after the game, a move that I somehow failed to consider. However the consequences of that are unclear, while the game move wins very cleanly.
17...b6 18.Bxa5 Qxb1 19.Rxb1 bxa5 20.Rb7++- Black resigned - 1:0.
This might seem a bit premature, but there is nothing to be done here. White will play Rcc7 next, and then possibly something like e5 and Nd4 with big mating threats, while Black can only sit and wait.
In a predecessor game followed: 20...Ke8 (20...Kd8 21.Rcc7 Bf8 22.Ne5 Rg8 23.d6) 21.Rcc7 Bf8 22.Ne5 (22.e5! Rd8 23.d6 exd6 24.e6 fxe6 25.Ng5 d5 (25...Rg8 26.Ne4) 26.Nf7+-) 22...a4 (22...f6 23.Nc6) 23.Rxa7 Rxa7 24.Rc8#, Guilbert - Schut, Bethune 2006 (CD Meyer).

Freilich nicht 78.Kc4?? patt bzw. 78.b3+?? Kb5=. Nach dem Textzug jedoch erobert Weiß mittels Opposition ein Schlüsselfeld seines b-Bauern [78.b5 Kxb5 79.Kb3 Kc5 80.Ka4+-].

32.Txa6!!
Der ehemalige Jugendweltmeister läßt sein großes Talent aufblitzen. Der mutige, chancenreiche Textzug ist ein fulminantes, spekulatives Turmopfer zwecks Freilegung des Schlüsselpunktes f6 und nachhaltiger Schwächung der feindlichen Königsstellung!

Was nun? Bloß nicht 37...Txd5?? wegen 38.Lc3! Ted8 39.Sxe4! und angesichts der Drohungen Lxe5 und Lb4+ wäre Schwarz verloren.
38.Lc5+??
Erliegt kurz vor der Zeitkontrolle einer Verführung. Darauf hat der glückliche Verteidiger zwar nur eine Parade, aber die ist mehr als ausreichend!
Dem tapferen Angreifer ist auf die Schnelle folgende forcierte Remisabwicklung entgangen: 38.Txf6 Dxf6 39.Lxf7 Dg7 (39...Le3+? 40.Lxe3 Sxf7 41.Sxe4; 39...Dxf7?? 40.Lc5+) 40.Dxg7+ Lxg7 41.Lxe8=, und nach dem weiteren 41...e3! 42.Sxc4 bxc4 43.Lxe5 Lxe5 44.Lb5= wäre aus dem Kampfgetümmel keiner als Sieger hervorgegangen.

Es könnte noch folgen: 44.Kg2 (44.Sxg3 Sg4+) 44...Dxb2+ 45.Kf1 (45.Lf2 Td7; 45.Sf2 Td7) 45...Td7-+.

56.Lh8+?
Originell, aber inkorrekt, was am Turnierbrett freilich nicht vorauszusehen ist! Alternativen:
I Das dreiste 56.Lg7+? funktioniert überhaupt nicht: 56...Kxg7 57.Df6+ Kg8 58.Dxe6+ (58.Dd8+ Kg7 59.Df6+=) 58...Df7 59.Df6 (Weiß muß schon die Notbremse ziehen, denn 59.Dxg6+? scheitert an 59...Dxg6+ 60.Kxg6 Sxe5+!-+) 59...Dxf6+ 60.Kxf6 g5 61.e6 Kf8 62.Kxg5 Ke7 63.Kf5 Sd6+ 64.Ke5 Sc4+ 65.Kxd5 Se3+ 66.Kc6=
II Eine beispielhafte Gewinnführung lautet: 56.Dc2! Dg8 (56...Se3? 57.Dc7+ Kg8 58.Dd8+ Kf7 59.De7+ Kg8 60.De8#) 57.Dh2 Sa3 (57...Ke8 58.Kh6 Se3 59.De2 Sc4 60.Dd3 Kf7 61.Df3 Ke8 (61...Sd2 62.Da3+-) 62.g5 Zugzwang! Kf7 (62...Df7 63.Dd3; 62...Sd2 63.Da3 Df7 64.Dd6+-) 63.Lg7+ Ke8 64.Kxg6+-) 58.Df2:

56...Kg8 57.Df6?!
Der Großmeister findet keine Patentlösung und versucht es mit der Brechstange. Richtig ist die Stellungswiederholung mit 57.Lf6 Kf7 und nun 58.Dc2! nebst dem Zugzwang-Manöver wie gezeigt.
57...Dxh8?
Schluckt den vergifteten Köder und stellt seine Dame damit ins Abseits.
Allein zu versuchen war: 57...Dc7/Dd7 und nun: 58.Kxg6 (58.Dxg6+ ist auch beachtlich: 58...Kxh8 59.Kf6 Dd8+ (59...Dd7 60.Df7 Dd8+ 61.Kxe6 Dc8+ 62.Ke7! (62.Kxd5?

c) 59...Dc7! ist die einzige Verteidigung, um mit der Dame über die c-Linie rettend eingreifen zu können! 60.Dh6 Sd2 (60...Dh7? 61.Dxh7+ siehe 59...Dd7/60...Dh7) 61.Kf4 (61.Lf6? Sf3+! 62.Kh5 einziger Zug (62.Kf4?? Dc1+) 62...Dh7) 61...Sf1! (61...Dh7? 62.Dxe6+ Kxh8 63.Dxd5 Dh6+ 64.g5+-) 62.Dxe6+ Kxh8 63.Dxd5 Dc1+= 64.Ke4 Sg3+ 65.Kd3 Dd1+.
