[#]1.d4 口6 2.c4 e6 3.口3 b6 4.a3 半7 5.勺3 d5 6.cxd5 巳d5 7.卡2 This flexible continuation was introduced in practice by grandmaster Smbat Lputian. 7...千7 8.巳d5 台d5 9.θ2 c5 10.e4 半7 I encountered this position thrice for the recent few months. 11.d5 This rather sharp continuation I employed for the first time against Karpov. [In the first game, which took place in the match Russia-the World, after: 11.圬1 cxd4 12.巳d4 a6 13.占3 占7 (In my second game, at the FIDE World Cup, Anand varied with: 13...b5 14.f3 占7 15.占2 圭8 16.ι2 叉5 17.O-O O-O 18.b4 勺4 19.台c4 bxc4 20.叉2 ㄉd2 21.寺d2 卉6 22.勺3 , and the game also finished with draw.) 14.占2 θ8 15.η1 勺5 16.f3 O-O 17.O-O η8 18.b4 兀4 19.θ2 b5 20.圭1 卡6 21.g3 , the draw was agreed in Dreev - Leko, 1/2] 11...exd5 12.exd5 卡6 13.O-O-O O-O 14.半5!? I found this moce when analyzing my game against Karpov, since [White obtained no opening advantage after: 14.土5 口6 15.▁1 占5 16.口3 卡4 Dreev-Karpov, Cap d'Agde] 14...h6 It is rather a tardy move, but it seems quite logical, since Black establish control over the g5-square. [For example, the immediate: 14...口6 , is followed by: 15.卮5] I deecided to start with: 15.卉3 , because [in the case of the strightforward: 15.h4 口6 16.土5 (After: 16.卉3 , possible is: 16...巳d5) 16...占5 , White obtains nothing. (16...占7)] [After: 16...台c6 17.dxc6 圭8 18.ζ4 , Black experiences certain difficulties.] 17.h4 My opponent underestimated this move. 17...土4 The only move, White threatened with 土5. 18.▁1 This useful move prepares the 土5 maneuver. 18...卉8? As I found out in my conversation with Srgei after the game, he did not want to admit 土5 and staked his hopes on the following g7-g6. However, the move 18...卉8 was his decisive mistake. 19.圬e1! An important preparatory move. [I considered, that after: 19.土5 hxg5 20.hxg5 f5 , White's attack is not sufficiently strong.] 19...g6 Black also cannot survive with other moves. [For example: 19...b5 20.土5 hxg5 21.hxg5 f5 22.gxf6 巳f6 23.μ6 (23.多6!?) , and if: 23...b4 , then: 24.axb4 cxb4 25.卡4 , and Black has nothing to prevent the white rooks' building-up on the h-file after: 26.圯4, or: 26. 多4; In the case of: 19...卡7 20.土5 , White wins again with: 20...hxg5 21.hxg5 f5 22.gxf6 巳f6 (22...寺f6 23.ν7 ▅7 24.台d7 ㄉd7 25.圯6) 23.μ6 After: 23...台c6 (Black's other defensive attempt: 23...θ8 , threatening with 卯5+, leads after: 24.台d7 ㄉd7 25.圯6 占7 26.圯3 κ8 27.λ5 θ8 28.ㄉc8 在xc8 29.寺e7 圩7 30.多8 , to the endgame winning for White.) 24.dxc6 圯8 (24...圩7 25.多3; 24...θ7 25.圯6 叉8 26.ν7 ▅7 27.多e1) 25.圬1 圯6 26.多7 θ7 27.圬h1 , White must win.; And after: 19...θ7 , White also wins with: 20.土5 hxg5 21.hxg5 f5 22.gxf6 巳f6 23.台f6 gxf6 24.多6; After: 19...f6 , White brings his queen into the attack by: 20.μ6 b5 21.土5 hxg5 22.hxg5 叉5 23.ν7 ▅7 24.多6 obtaining the decisive advantage.]
[The case is, that after: 22...g5 , White has a very strong continuation: 23.e7!! , opening the very important a2-g8 diagonal. After: 23...台e7 (in the case of: 23...ㄉe7 , White has an opportunity of: 24.卡5 ▇7 25.圯1 , and after any black queen's normal retreat, say: 25...θ7 , deciding is: 26.占6 , when Black cannot protect the f5-pawn.) 24.圬1 θ7 , White plays: 25.η3 圩7 26.κ6 卯6 27.圬7 , winning.] Black has to play 22...gxh5, but after: 23.寺h5 , White obtains an irrefutable attack. 23...κ7 24.士4 ㄉe6 25.巳f5 占5 26.卡5! Black resigned. [1:0] |
