X0 QGD Semi-Slav, Stolz variation, 6.Qc2 [D45].

1.d4 X1 d5 X2 2.c4 X3 c6 X4 3.Nc3 X5 Nf6 X6 4.e3 X7 e6 X8 5.Nf3 X9 Nbd7 X10 6.Qc2 X11 Bd6 X12 7.g4! X13

This White reply was introduced in 1992, apparently in the game Kolbe, Joachim - Liesecke, Alfred (46 m.) 1-0 [D45] Oberliga Nord O 9192 1992. Since this date this pushing of the g-pawn knows an increasing success and was employed by many Grandmasters as Garry Kasparov, Akexei Shirov, Vladimir Akopian, Evgeny, Bareev, Boris Gelfand, Miroslav Markovic, Veselin Topalov and many others! ... As shows clearly Chessbase' s statistics, White obtains good results and it is not easy for Black to find an appropriate defense.

[ The main line is: 7.Be2 X14 0-0 X15 8.0-0 X16 dxc4 X17 9.Bxc4 X18 as in the game: 9...a6 X19 10.Rd1 X20 b5 X21 11.Be2 X22 Qc7 X23 12.Bd2 X24 c5 X25 The thematic lateral advance in this kind of formation. 13.dxc5 X26 Qxc5 X27 14.b4! X28 Qc7 X29 15.Rac1 X30 Bb7 X31 16.Qb3 X32 Qb8 X33 17.h3= X34 Navara, David (2663) - Gelfand, Boris (2724) (61 m.) 1/2-1/2 [D46] EU-chT Gothenburg 07.08.2005.; or: 7.Bd3 X35 leading to the same line.]

7...Nxg4 X36

For the pawn White wins a tempo of development and the opening of the g-file.

8.Rg1 X37 Qf6 X38

[ Is playable but favourable to White: 8...Nxh2?! X39 9.Nxh2 X40 Bxh2 X41 10.Rxg7 X42 Let us see for example: 10...Qf6 X43 11.Rg2 X44 Bd6 X45 12.Bd2 X46 b6 X47 13.e4 X48 Bf4 X49 14.cxd5 X50 exd5 X51 15.exd5 X52 Bxd2+ X53 16.Qxd2 X54 Bb7 X55 17.0-0-0 X56 cxd5 X57 18.Re1+ X58 Kd8 X59 19.Rg5 X60 It is clear that White owns a significant initiative for the sacrificed pawn (Dreev Alexey (2689) - Geller, Jakov (2489) (35 m.) 1-0 [D45] RUS-chT Sochi 20.04.2004).]

9.Rxg4 X61

The only correct suite.

9...Qxf3 X62 10.Rxg7 X63 Nf6 X64 11.h3 X65

This was the choice of Aronian, two years ago in Morelia/Linares.

[ In the following game: 11.Bd2?! X66 Ng4 X67 12.Rxg4 X68 Qxg4 X69 13.h3 X70 Qh5 X71 14.Be2 X72 Qg6 X73 15.e4 X74 e5 X75 16.dxe5 X76 Bxe5 X77 17.cxd5 X78 Qg1+ X79 18.Bf1 X80 Bxh3! X81 19.0-0-0 X82 Bxf1 X83 Black, with an extra-Rook and insufficient compensations for his opponent, deserves to win (in spite of the complexity of this singular position!) (Gubajdillin, Alexey (2504) - Solodovnichenko, Yuri (2541) (54 m.) 0-1 [D45] Belgorod Rectors Cup 4th 25.02.2008).]

11...Qf5?!N X84

After the Queen exchange Black pawn squelette is deteriorated.

[ The game Aronian versus Morozevich continued by: 11...h6 X85 12.Bd2 X86 e5 X87 13.Rg3 X88 Qh5 X89 14.cxd5 X90 exd4 X91 15.Ne4 X92 Nxe4 X93 16.Qxe4+ X94 Qe5 X95 17.Qxe5+ X96 Bxe5 X97 18.Rf3= X98 Aronian, Levon (2744) - Morozevich, Alexander (2741) (29 m.) 1/2-1/2 [D45] Morelia/Linares 24th 17.02.2007.]

12.Qxf5! X99

The most radical answer!

[ To try to avoid the Queen exchange gives nothing interesting: 12.Qe2 X100 e5! X101 13.cxd5 X102 Nxd5 X103 14.Nxd5 X104 cxd5 X105 15.Qb5+ X106 Kf8!= X107 ; Black does not have particular problems after: 12.Qd3 X108 Qxd3 X109 13.Bxd3 X110 Kf8 X111 14.Rg1 X112 dxc4 X113 15.Bxc4 X114 e5 X115 16.dxe5 X116 Bxe5 X117 17.f4 X118 Bc7= X119 ]

12...exf5 X120 13.cxd5 X121 cxd5?! X122

The inconvenience of this move is to allow White to play his Knight in b5 attacking the unprotected d6-Bishop.

[ After exchanges in d5 in another order: 13...Nxd5 X123 14.Bd3 X124 Be6 X125 15.Nxd5 X126 cxd5 X127 16.Ke2 X128 f4!= X129 White has only a residual advantage.]

14.Nb5! X130 Bb4+? X131

It is not a good idea to exchange dark-squared Bishops.

[ According to the fact that the Bishop is a long range piece it may be played: 14...Bb8 X132 15.Bd2 X133 Be6 X134 16.Rc1 X135 Kd7 X136 17.Ba5 X137 b6 X138 18.Bb4 X139 +/=]

15.Bd2 X140 Bxd2+ X141 16.Kxd2 X142 Ke7 X143 17.Bd3 X144 +/=

White has a plaisant position offering many perspectives.

17...Be6 X145 18.Nc7!? X146

A surprising but nice idea: if White exchanges his Knight against the "Bad" e6-Bishop, Black weak pawns will be difficult to protect (of course the pinned f7-pawn is immobilized!).

18...Rag8 X147 19.Nxe6 X148 Kxe6 X149

The only move!

[ Obviously is a blunder: 19...Ne4+?? X150 20.Bxe4 X151 fxe4 X152 21.Rag1 X153 Rxg7 X154 22.Nxg7 X155 and White wins without problem.]

20.Rxg8 X156 Nxg8 X157 21.Ke2 X158 +/-

"ChessBase - News - Carlsen-Anand:
Anand ponders his eleventh move"

Magnus Carlsen has fully realized his strategical objectives. And, on the other hand, Black is without prospects.

21...Ne7 X159 22.Kf3 X160 Rc8 X161 23.a4 X162 Rc7 X163

The Black Rook, indeed, controls the c-file, but is unable to penetrate in the other camp.

24.a5 X164 h6 X165 25.h4! X166

By pushing his pawns, White reduces Black possibilities.

25...Kf6 X167 26.h5 X168 Nc8 X169 27.Kf4 X170 Nd6 X171 28.Rg1 X172 Rc8 X173 29.f3 X174 Ke6 X175

Black is in a kind of zugzwang, whereas White increase progressively his advantage.

30.Rg7 X176 Rh8 X177 31.Bc2 X178 Rc8 X179 32.Bb3 X180 Rh8 X181 33.Rg1 X182 Rc8 X183 34.Rg7 X184 Rh8 X185 35.Rg2 X186 Rc8 X187 36.Rg1 X188 Ne8 X189 37.e4 X190 fxe4 X191 38.fxe4 X192 Nf6 X193 39.e5 X194 Ne4 X195 40.Ke3 X196 b6 X197 41.axb6 X198

[ May be considered: 41.Bd1!? X199 threatening: Bg4+ and secondarily: Bf3. For example: 41...Rc7 X200 42.Rg8 X201 bxa5 X202 43.Bg4+ X203 Ke7 X204 The only move. 44.Bf3! X205 Rc1 X206 45.Ra8 X207 Presumably White wins but the position is very complicated.]

41...axb6 X208 42.Kd3 X209 Nf2+ X210 43.Ke2 X211 Ne4 X212 44.Ke3 X213 f6 X214 45.Rg6! X215 Rc1 X216 46.Rxh6 X217 Rh1 X218 47.Bc2 X219 Rh3+ X220 48.Kf4 X221 Rh4+ X222 49.Kf3 X223 Nd2+ X224 50.Ke2 X225 Rh2+?! X226

[ By taking in d4 Black increases seriously his chances to draw 50...Rxd4 X227 as seems to show the folowing line: 51.Rxf6+ X228 Kxe5 X229 52.Rf5+ X230 ( 52.Rxb6 X231 ) 52...Ke6 X232 53.h6 X233 Ne4 X234 54.Rh5 X235 Rd2+ X236 55.Ke3 X237 Rxc2 X238 56.h7 X239 Rc8 X240 57.h8Q X241 Rxh8 X242 58.Rxh8 X243 Nd6 X244 and White is probably unable to win, even while managing to take the b-pawn!]

51.Kd1 X245 Nc4 X246 52.Rxf6+ X247 Ke7 X248 53.Bg6 X249 Rd2+ X250

Excepted in this 53th move, Black finds the more appropriate defense.

54.Kc1 X251

[ The problem is to know if the White King must favour to support the b-pawn or instead the h-pawn. His playable: 54.Ke1 X252 Rxd4 X253 55.b3 X254 Nxe5 X255 56.Rxb6 X256 Rh4 X257 57.Bf5 X258 Nf3+ X259 58.Kf2 X260 Rf4 X261 but without an obvious winning play line!]

54...Rxd4 X262 55.b3 X263 Nxe5 X264 56.Rxb6 X265 Rh4 X266 57.Bf5! X267 Nf3 X268 58.h6! X269

How to win a winning game? It is the problem. In the present case, it is remarkable to see how Magnus finds probably the only way to win:

1°) The h-pawn is going to promotion.
2°) The Knight go to d4 attacking the Bishop.
3°) The pawn reaches the h7-square.
4°) The Knight takes the Bishop.
5°) The pawn reaches the h8-square and is promoted to Queen.
6°) The Black Rook takes the Queen.
7°) The White Rook takes the Black one.

58...Nd4 X270 59.h7! X271 Nxf5 X272 60.Rb8 X273 Nd4 X274 61.Kb2 X275 Kd6 X276 62.h8Q X277 Rxh8 X278 63.Rxh8 X279 Kc5 X280 64.Rh5 X281 Nc6 X282 65.Rh4 X283 Nb4 X284 66.Ka3 X285 d4 X286 67.Rh5+ X287 Nd5 X288 68.Kb2 X289 Kc6 X290 69.Ka3 X291 Kc5 X292 70.Rh4 X293 Nb4 X294 71.Rh8 X295 Nc6 X296 72.Rh5+ X297 Kd6 X298 73.b4 X299 d3 X300 74.Rh3 X301

Now White wins in any case!

74...Ne5 X302 75.Kb3 X303 d2 X304 76.Kc2 X305 Nc6 X306 77.Rh4 X307 Kd5

A great Magnus Carlsen' s game!
