X57 Rb8
X58 14.Qf2
X59 e5
X60 15.fxe5!N
X61 The novelty that Magnus Carlsen has found for this game.
[
In this position Michael Adams versus Anand chose to pursue by:
15.Nde2
X62 The standard reply.
15...exf4
X63 16.Bb6
X64 Qe7
X65 17.Nxf4
X66 Be6

15...dxe5
X73 [
Of course, an alternative choice is to take back the pawn by the Knight:
15...Nxe5!?
X74 but, at the analysis, this reply may be risked:
16.Bg5
X75 (
Not the weak answer:
16.Be2?!
X76 which may be followed by by the play line:
16...Neg4
X77 17.Bxg4
X78 Nxg4
X79 18.Qf4
X80 Nxe3
X81 19.Qxe3
X82 = In this rather open position, Black owning a pair of Bishops against two Knight, does not have any problem. )
16...Nfg4
X83 17.Qg1!
X84 Presumably the best move. (
Is not so good:
17.Bxg4?!
X85 Nxg4
X86 18.Qg3
X87 Qb6
X88 19.Nb3
X89 Be6
X90 20.a5
X91 Qc7
X92 21.Nd4
X93 Ne5
X94 +/= and Black has practically equalized. )
17...Nxf3!?
X95 18.gxf3
X96 Ne5
X97 19.Nd5
X98 Qc4
X99 20.Ra3
X100 Be6
X101 21.Rc3!
X102 And then Black has only one way for continuing:
21...Bxd5
X103 22.Rxc4
X104 Bxc4
X105 White has a significant advantage but the game is not clear.]
16.Nb3
X106 Nb4!?
X107 [
16...Be6
X108 is obviously a good alternative. The two Bishops control adjacent open diagonals a3-f8 and a2-g8. Is then playable:
17.Rad1
X109 Nb4
X110 and then for example:
18.Bb6
X111 Qc6
X112 19.Na5
X113 Qc8
X114 20.Ba7
X115 Ra8
X116 21.Be3
X117 Be7=
X118 ]
17.Ba7
X119 Is usual in such a position, before to play the Bishop in b6. The Rook is forced to go back in a8.
17...Ra8
X120 18.Bb6
X121 Qe7!
X122
In all this phase White has the initiative, but Black finds a relatively accure defense, preserving his chances to equalize.
[
It is not advised to play:
18...Qc6?!
X123 because;
19.Na5
X124 Qe6
X125 20.Rad1
X126 Be7
X127 (
It is frankly a bad idea to take the c2-pawn:
20...Nxc2??
X128 21.Nd5!
X129 Nxd5
X130 22.exd5
X131 Qf6
X132 23.d6
X133 Nd4
X134 24.Bxd4
X135 exd4
X136 25.Qxd4
X137 Rd8
X138 26.Bd5!
X139 and White has a winning game! )
21.Rd2!
X140 +/= with a significant White initiative.]
19.Rad1
X141 Be6?!
X142 An inaccurate move allowing White to pursue develop his progression on the Queen side with threat.
[
Black has the opportunity of an active defense:
19...Bg4
X143 20.Bxg4
X144 Nxg4
X145 21.Qe2
X146 Qh4
X147 22.h3
X148 Qh6
X149 23.Bg1
X150 Nf6
X151 +/= White has a little advantage due to the control of the d-file.]
20.Nd5!
X152 With the idea to create a dangerous passed pawn on the d-file.
[
Is not so sharp than the Magnus' choice:
20.Nc5
X153 Bc4
X154 21.Rfe1
X155 Rac8
X156 22.Nd5
X157 White of course has a clear advantage but Black may choose to continue by 22...Bxd5 or 22... Qd6.]
20...Bxd5
X158 The only correct reply.
[
20...Nbxd5?
X159 loses a pawn:
21.exd5
X160 e4
X161 22.dxe6
X162 exf3
X163 23.exf7+
X164 Qxf7
X165 24.Qxf3
X166 +/-;
Is a blunder:
20...Nfxd5??
X167 21.exd5
X168 Bf5
X169 22.d6
X170 Qe6
X171 23.Nc5
X172 + - and White wins.]
21.exd5
X173 e4
X174 22.d6
X175 Qe6?!
X176 The subjacent idea is to play the Queen en f5 in view to exchange the Queens. But the resulting endgame will be favourable to White.
[
The only accurate defense is:
22...Qe5
X177 23.d7
X178 Nxd7
X179 24.Rxd7
X180 exf3
X181 25.Qxf3
X182 Re7
X183 (
25...f6
X184 26.Nd4
X185 Qe4!
X186 Forcing more or less the Queen exchange. Among other alternatives, it may follow:
27.Rxb7
X187 Rac8
X188 28.c3
X189 Nd3
X190 29.Qxe4
X191 Rxe4
X192 +/= White has only a small advantage and the game is not clear. )
26.Rxb7
X193 Rxb7
X194 27.Qxb7
X195 Qe8!
X196 and then possibly
28.c4
X197 with only a little White advantage.]
23.Nc5!
X198 Qf5
X199 24.Be2
X200 Qxf2
X201 25.Rxf2
X202 Nbd5
X203 The best choice indeed.
26.a5
X204 Seems correct but this move is not the best opportunity for White.
[
Rather strong is:
26.Rxf6!
X205 Nxf6
X206 27.a5
X207 Rec8
X208 28.c4!
X209 +/- and then Black is practically in zugzwang. (
28.b4
X210 Rc6
X211 forcing the advance of the d-pawn.
29.d7
X212 Rxb6!
X213 In view ta take back the control of the d8-square.
30.axb6
X214 Rd8
X215 31.Nxb7
X216 Rxd7
X217 32.Nc5
X218 Rxd1+
X219 33.Bxd1
X220 and White has a winning advantage. ) ]
26...Nxb6
X221 27.axb6
X222 Rab8?
X223 A serious mistake.
[
Black did not have a better possibility than:
27...Rec8!
X224 28.b4!
X225 Rc6
X226 29.Nxb7
X227 Rxb6
X228 30.d7
X229 Rxb7
X230 31.d8Q
X231 Rxd8
X232 32.Rxd8
X233 Rxb4
X234 33.Kg1
X235 Rb6
X236 The ending is unclear and Black has some chances to draw.]
28.Rxf6!
X237 Taking the full control of the d7-square.
28...gxf6
X238 29.Nd7!
X239 The only winning move.
29...f5
X240 30.c4!
X241 A strong answer among other alternatives. Black can undertake nothing.
30...a5
X242 31.c5
X243 Bg7
X244 32.Nxb8
X245 Rxb8
X246 33.Ba6!!
X247 A superb rip off!
33...Bf6
X248 [
The Bishop is untouchable since:
33...bxa6??
X249 34.c6
X250 Rxb6
X251 35.c7
X252 Bf6
X253 36.c8Q+

34.Bxb7
X255 Rxb7
X256 35.c6
X257 Rxb6
X258 36.Rc1
X259 Bxb2
X260 37.d7
A beautiful Carlsen' s game in spite of some inaccurate replies of his opponent.
1-0
