World Chess Championship 2008 Bonn (7), 23.10.2008

* [Repa,Jason]*

1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 **Kramnik opts for the relatively harmless Slav (proper). This position has been reached in their previous encounters on two ocassions, although with Anand on the Black side. Both games, predictably, resulted in draws.

**5.a4 Bf5 6.e3**[Marin,M: Also slightly unexpected. Topalov usually plays the more straightforward 6.Ne5 Nbd7 7.Nxc4 Qc7 8.g3 e5 9.dxe5 Nxe5 10.Bf4 Nfd7 11.Bg2 g5 12.Nxe5 gxf4 13.Nxd7 0-0-0 14.Qd4 Qxd7 15.Qxf4 Bd6 16.Qc1 (16.Qh6 Qe6

**9.Qe2 Bg6 10.e4 0-0 11.Bd3 Bh5 12.e5**[From the point of view of the general laws of development, 12.Bf4 looks slightly more consistent and only if 12...Re8 , then 13.e5 . However, after 13...Nd5 14.Nxd5 Black can try 14...exd5!? already, with interesting play.]

**12...Nd5 13.Nxd5 cxd5 14.Qe3**Marin,M: 'Topalov switches back to the classical main line of the Slav, which brought him close to what could have easily been his best achievement in the whole match (see the tragically ended second game).'

**14...Re8**Topalov - Kramnik, World Ch. game#2, (Elista, 2006) continued; [14...Bg6 15.Ng5 Re8 Marin,M: 'would just transpose to the second game.' 16.f4 Bxd3N In spite of the fact that the previous games played from this position did not justify any special worries for Black, Kramnik decides to restrict White's attacking chances to the minimum.

However, Topalov had other plans. By gradually concentrating all his forces on the king side, he will aim to create very dangerous threats. This was to a certain extent in accordance with his general match strategy. Instead of rushing in, he mostly preferred to take his chances in long battles. 18.Be3 (Taking into account Black's possible improvements on the 19th move, 18.g4 deserves serious attention. 18...h6[] (18...g6?! 19.gxf5 gxf5

*(19...exf5 20.Qb5+-)*20.Qg3+- for instance 20...Qe7 21.Nxe6+ Kh8 22.Ng5 h6 23.Qh3! and White avoids any inconveniences along the g-file.) 19.Nxe6!

*(21.gxf5 exf5)*21...Nxe6 22.gxf5 Nc7 23.Rg1 Kh8 and White's attacking chances are questionable.) 19...Rc8?! Black systematically prepares his queenside counterplay, but tolerates the knight on g5 for too long.

**a)**True, 19...h6?! would have been risky by weakening the g6-square unnecessarily. 20.Nxe6!?

*(20.Nf3 Rc8 21.Rg1)*20...Nxe6 21.Qxf5©;

**b)**However, 19...Be7! as recommended by several commentators was better. 20.Nxe6?!

*(20.Nf3*is safer, but then White should abandon his attacking ideas, since

True, I felt fully rewarded for it by the spectacular sequence starting with the 28th move. (However, 22.Nxe6!? might have been a more dangerous continuation of the attack. 22...Qxe6

Without calculating too much, it is obvious that the position becomes very dangerous and that Black needs to play very accurately in order to avoid disaster. 26...Rb4! The only way to stay alive is to question the stability of the white queen along the b1-h7 diagonal. 27.h5 Qb5 28.Qc2!!

*(*The only way to keep the attack going.

*28.hxg6?*was premature because after

*28...Qxd3 29.gxh7+ Kxh7 30.Rg7+ Kh6 31.f5+*the bishop is hanging.

*)*28...Rxb2! For the time being, Kramnik finds the only path through the jungle of variations, most possible by intuition. (28...Rb3?! has been unanimously recommended as a safer defence, but it allows White to retain an advantage. 29.hxg6 h5

*(29...Qd3? 30.gxh7+ Kh8 31.Rg8+ Kxh7 32.Qh2++-)*30.R4g3!

*(30.g7 hxg4 31.gxf8Q+ Kxf8 32.Qh7 Qd3=*and White has not more than perpetual, as pointed out by Svidler.

*(30...h4 31.g7 hxg3 32.gxf8Q+ Kxf8 33.Qg6 Qd3 34.f5! Qxe3 35.Rxg3+-)*31.g7!! Quite similar to the game continuation. 31...Nh7

*(31...Qxc2? 32.gxf8Q+ Kxf8 33.Rg8+ Kf7 34.R1g7#)*32.Qc7 White's army is much better coordinated. Several of Black's pieces are passive or even vulnerable.

*(*If White fears the queenside passed pawns from the main line, he can also choose the safer

*32.Qxd3 Rxd3 33.Bd2)*32...Qc4

*(32...Qb5 33.Nd2+/-)*33.Qxc4 dxc4 34.Nd2 Rxb2 35.Nxc4 Rc2 36.Nd2+/- and White's kingside pressure is hardly bearable. With four rooks on the board, Black's queen side pawns are much less dangerous than in the game. Still, the position would remain complicated and difficult to handle in an over-the-board game.) 29.hxg6! Now, capture of the queen leads to mate, so Black has to keep the g-file closed, at least for a while. 29...h5[]

*(29...Rxc2? 30.gxh7+ Kxh7 31.Rg7+ Kh6 32.f5+ Kh5 33.f6+-)*30.g7! hxg4 31.gxf8Q+ Bxf8? This move should have led to an abrupt end. (Both players started missing things by this moment. This is easy to spot when assisted by Fritz, but in conditions of over-the-board play things are different. About the previous day's game it has been said that 57...f5 was a terrible blunder and that 57...Nxf2 would have drawn easily. I do not feel that this is really so obvious without an engine by one's side. Anyway, I suppose that Kramnik considered the line 31...Kxf8 32.Qg6 Qe2 33.Qxg4 as completely hopeless for him, overlooking the unexpected resource 33...Bg5! when White has to insert 34.Re1 before he captures the bishop. 34...Qc2 35.Qxg5

*(35.fxg5 Kg7 36.Rc1 Rh8+ 37.Kg1 Rb1 38.Rxb1 Qxb1+ 39.Kf2 Rf8~~*Svidler

*(*Both players must have had their eyes focused on the king side, which made them overlook that after

*32.Rxg4+ Bg7*White can attack the g7-bishop from the other side with

*33.Qc7*preventing ...Re7 (which could follow after 33. Qg6) and leaving Black with the possibility of giving just one last check with

*33...Qf1+*when

*34.Ng1*ends the day. Although Topalov's move does not let the win slip away yet, it surely marks the start of his gradual decline, after a brilliantly conducted first part of the game. This seems to be a hidden weakness of the FIDE World Champion. Sometimes, if the opponent gets some symbolic counterplay in a basically lost position, Topalov starts becoming less confident. (To a certain extent, this was also typical for Fischer, with whom Topalov has been frequently been compared for his uncompromising style). In Topalov-Leko Linares 2005 and Topalov-Anand San Luis 2005 he just missed relatively simple wins but in Aronian-Topalov Morelia 2006 he even came close to losing at a certain moment. This game continues this unfortunate tendency: he will eventually lose the full point...

(Kramnik was probably afraid that after 37...Qxc2 White would get a decisive tempo with 38.Ng5 In fact, now that the king's defence has been somewhat weakened, the checks would have allowed him save the game. 38...Qb1+ 39.Kg2 Qc2+ and White should probably accept a draw by perpetual check or repetition somewhere. 40.Kh3!?

Black desperately tries to simplify the position, even if this would imply making some positional or material concessions on the kingside since his apparently inoffensive queenside pawns will be a terrible weapon in the ending. White faces now a very difficult choice right before the control. (39...Qf5 40.Qxf5 exf5 41.Ng5 Rc7

(It required a lot of analytical effort to prove which exactly is the move that turns a better (or winning) position into a worse (or losing) one, but it is obvious that we are getting close by now. 40.Qxe4 dxe4 41.Ng5 would have lead to relatively similar positions as in the game, with the difference that White could put his pawns into motion more quickly. For instance 41...Bf8

**a)**Topalov likes to do things in a systematic way, approach with the king, maintain the chain of pawns intact, and so on, but there is simply not enough time for it! There are two enemy passed pawns on the other wing! Capturing the bishop with 42.fxg7 Rxg7+ 43.Kf2~~;

*(*When Nunn announced that

*53...Re3*is here the only winning move, I could not spot the reasons behind that immediately. Apparently, it has something to do with the restriction of the knight, but the real explanation will be revealed slightly later. Here follow Nunn's analysis and comments: "

*54.d5 Kf8 55.Kd7 b5 56.Ne6+ Kg8 57.d6 b4 58.Nc5*the rook controls b3 and is therefore ready to support the b-pawn without wasting a tempo. Then the continuation

*58...Kf7 59.Kc6 Rc3 60.Kb5 b3 61.Na4 Rc2 62.d7 Ke7*leads to a ar win. It is interesting to note that all Black's moves from move 53 to move 62 are unique winning moves (apart from a possible repetition at one point). Of course this would be tough to find in a game. I think the hardest part is the manoeuvre ...Kg8-f8-g8-f7, which looks quite paradoxical. (Nunn)"

*)*54.d5 Kf8 55.Ne6+ (But now, 55.Kd7 , preventing the approach of the enemy king, looks better for human standards and it is the only saving move according to the tablebases, too. So, humans and computers can have common views sometimes... 55...b5 56.Ne6+ Kf7
