Sicilian Najdorf, 6.Be3: (B90) 1.e4 X1 c5 X2 2.Nf3 X3 d6 X4 3.d4 X5 cxd4 X6 4.Nxd4 X7 Nf6 X8 5.Nc3 X9 a6 X10 6.Be3 X11 e5 X12 7.Nb3 X13 The usual answer. [ For: 7.Nf3!? X14 see the game Ivanchuk, Vassily (2750) - Topalov, Veselin (2783) 1-0, (B90), Morelia/Linares (2), 2007.] 7...Be6 X15 This B90-Quasi Pure Opening (see also: B92) is very frequently played since the game Cardoso, Radolfo Tan - Jezek, Jaroslav, 0-1, (B92), Moscow ol. (men), 1956. It is interesting to notice that this line offers similar chances to White and Black (approximately 1/3 won by each side and 1/3 drawn). 8.Qd2 This move (anyways, Qd2 is a thematic move of all this variation, preparing the White Queenside castle) has been introduced in 1971 by Byrne (Byrne, Robert E (2510) - Balashov, Yuri (2570), 1-0, (B90), Alekhine mem, 1971). X16 The corresponding position (B90-Totally Pure Opening) is the start point of some very popular lines many often played nowadays at all levels. [ The main line continues by: 8.f3 X17 Be7 X18 9.Qd2 X19 0-0 X20 10.0-0-0 X21 Nbd7 X22 11.g4 X23 b5 X24 12.g5= X25 (about 500 games in Database) e.g.: 12...b4 X26 13.Ne2 X27 Nh5 X28 14.Ng3 X29 g6 X30 15.Nxh5 X31 gxh5 X32 16.f4 X33 exf4 X34 17.Bxf4 X35 Ne5 X36 18.Kb1 X37 Qc7 X38 19.Nd4 X39 Bg4 X40 20.Be2 X41 Nc4 X42 21.Bxc4 X43 Qxc4 X44 22.Nf5+- X45 Brkic, Ante - Zufic, Miroslav, 1-0, (B90), Zupanja, Zupanja op-A 13th, 2007] 8...Nbd7 X46 [ In 2006, Topalov has played against Judit Polgar: 8...Be7 X47 9.f4 X48 exf4 X49 10.Bxf4 X50 0-0 X51 11.0-0-0 X52 Nh5 X53 12.Be3 X54 Nc6 X55 13.Kb1 X56 Nf6 X57 14.Nd4 X58 Nxd4 X59 15.Bxd4 X60 Nd7 X61 16.Be3= X62 and the position leads clearly to a draw. (Topalov, Veselin - Polgar, Judit, 1/2-1/2, (B90), Bilbao blindfold m, Bilbao, 2006).] 9.0-0-0!? X63 [ The main continuation is: 9.f3 X64 ] 9...Be7 X65 10.h3N The habitual answer is: 10.f3, with three objectives: 1) Protect the e-pawn, 2) Control the g4-square, 3) Prepare the advance: g2-g4-g5. The Anand' s novelty falls in the first of this points and perhaps is not very relevant. X66 Nevertheless, f2-f4 is now playable without risk and possible it is the Anand' s idea! [ A great sharp line many often played since 2002 is: 10.f3 X67 0-0 X68 11.g4 X69 b5 X70 12.g5 X71 b4 X72 13.Ne2 X73 Ne8 X74 14.f4 X75 a5 X76 15.f5 X77 a4 X78 =/+ The position is unclear and leads to contrasted results.] 10...b5 X79 11.g4 X80 0-0 X81 12.Kb1 X82 Qc7 X83 13.Bg2 X84 Now, reasons of Anand' s novelty are most clear; in particular the g2-Bishop participates in the control of the critical d5-square. The position is equal. 13...Nb6 X85 But the doubtful aspect of Anand' s innovation appears only now and resides in the giving up by White of the strategic a6-f1 diagonal. 14.Bxb6!? X86 [ Leads presumably to a drawn position: 14.Nd5 X87 Bxd5 X88 15.exd5 X89 Nc4 X90 16.Qd3 X91 Nxe3 X92 17.fxe3= X93 ] 14...Qxb6 X94 Finally, Black has pair of Bishop, whereas White has only a rather bad one! 15.f4 X95 This Break move is the justification of all White strategy. 15...Bc4! X96 16.g5?! X97 Seems natural, but now the Black Knight is able to reach the f4 square. [ Notice that after: 16.Bf1 X98 Bxb3 X99 17.cxb3 X100 b4 X101 18.Nd5 X102 Nxd5 X103 19.exd5 X104 exf4 X105 20.Qxf4 X106 Bf6 X107 =/+ Black has only a little advantage.] 16...Nh5! X108 17.fxe5 X109 dxe5 X110 18.Nd5 X111 Obviously, the only White counterplay available. 18...Bxd5 X112 19.exd5 X113 Bd6 X114 This time, the strategic f4-square is totally under Black control, what means the failure of White plan. 20.Na5 X115 f5 X116 21.gxf6 X117 Rxf6 X118 22.Rhf1 X119 =/+ [ Is equally favorable to Black: 22.Nc6 X120 Ng3 X121 23.Rhg1 X122 Qf2 X123 24.Rge1 X124 Qxd2 X125 25.Rxd2 X126 Re8 X127 =/+] 22...Re8 X128 23.Rxf6 X129 Nxf6 X130 24.Nb3 X131 e4! X132 25.Nd4?! A tactical mistake because the d5-pawn is temporarily unprotected. X133 But a careful study of playable variations does not succed in showing that this is a losing move; now White know some troubles, but Black has a great difficulty to reinforce significantly his advantage.. [ A correct defense seems to be: 25.Qe2 X134 In particular the White Queen controls the g4-square, allowing the advanced: h3-h4; and then possibly: 25...Re5 X135 26.Re1 X136 a5 X137 27.c3 X138 a4 X139 28.Nd2 X140 e3 X141 29.Nf3 X142 Re8= X143 ] 25...Re5! X144 -/+ 26.c3!? X145 It is not easy to find here a satisfactory retort, and this one is not so bad! [ Is impossible: 26.Ne6?? X146 Rxd5 X147 27.Qc1 X148 Rxd1 X149 28.Qxd1 X150 Qf2 X151 -+; However, facing the plausible White answer: 26.Qc3?! X152 Black takes progressively a winning advantage: 26...Qc5 X153 27.Qxc5 X154 Bxc5 X155 28.Nb3 X156 Bf2 X157 29.d6 X158 e3 X159 30.Nd4 X160 e2 X161 31.Nxe2 X162 Rxe2 X163 32.Bc6 X164 Bb6 X165 -+] 26...Qc5?! X166 =/+ With this inaccurate move, very little Black chances of winning bring down; and the game may possibly be a draw. [ The best opportunity for Black seems to be: 26...Rxd5!? X167 but it is rather difficult to investigate the great number of playable continuations. We may propose, only as an example: 27.Qe2 X168 Re5 X169 28.Nb3 X170 Re8 X171 29.Nd2 X172 Qc6 X173 30.Nxe4 X174 Nxe4 X175 31.Rd4 X176 Nxc3+ X177 32.bxc3 X178 Rxe2 X179 33.Bxc6 X180 Be5 X181 34.Bd5+ X182 Kf8 X183 -/+ and then Black advantage is probably not enough for winning.] 27.Qe2! X184 Anand keeps his chance for a draw! 27...Nxd5 X185 28.Bxe4 X186 Nf6 X187 29.Nb3 X188 The only way. 29...Qc7= X189 [ The alternative line: 29...Qc8 X190 30.Rxd6 X191 Nxe4 X192 31.Qe3 X193 Qe8 X194 32.Rd1= X195 leads equally to the draw.] 30.Nd2 X196 Qe7 X197 31.Qd3 X198 Bc5 X199 32.Bg2 In this interesting game the battle has been truly engaged and Ivanchuk has perhaps (but it is not a certainty!) missed his chance! 1/2-1/2
