Souvik - Andrew game analysis

Following is the analysis of the interesting game between me and Andrew last weekend which ended in a draw.


Roychoudhury,Souvik (1984) - Grochowsky,Andrew (1700) [D35]

SWCC ICICLE Swiss Hales Corner (1.4), 03.01.2008


After the typical queen's gambit declined opening, we arrived at the following position




13.b4 Bb7 14.Qa4 May be a4-a5 here could have been better [14.Ne5 This could have been better. White can play Bh2-f4 type later if want.] 14...Bd6 15.Bxd6 [15.Ne5] 15...Qxd6 16.Rfc1 Rec8 17.Rc2 Ne6 18.Qb3 Rc7 19.Rbc1 Rac8 20.a4 a6 21.a5 b5




[21...c5 22.bxc5 bxc5 23.Qb6 Qe7 24.dxc5 Nxc5 25.Na4 Ne6 26.Rxc7 Rxc7 27.Rxc7 Qxc7 28.Bf5 Qxb6 29.axb6 Nd7 30.Nd4+/-] 22.Ne5?! [22.Bf5 Playing for the good knight bad bishop. white wants to exhange on e6 to bring one more pawn to the same color as bad black bishop. Then the c3 knight will go to c5 or e5 with a lot of pressure. The other knight can be exchanged for black's remaining knight. 22...g6 23.Bxe6 Qxe6 (23...fxe6 24.Ne5 Kg7 25.Ne2 Nd7 26.Qc3 Nxe5 27.dxe5 Qe7 Black's queenside is extremely vulnerable) ] 22...Ne8 [22...c5 I saw the move only after playing the Ne5 move. Didn't also see the Nb5 idea. 23.Nxb5 axb5 24.bxc5 Nxc5 25.Rxc5 Rxc5 26.Rxc5 Rxc5 27.dxc5 Qxe5 28.Qxb5+/=] 23.f4 Qe7 X-raying to the e3 pawn 24.Rf1 Nd8 25.Nd1 [25.Rf3 This was the better move to protect the e3.] 25...Nd6 26.f5 Qf6 27.Ng4





May be I could build more force with Rf2, Qc2 etc before Ng4. He can play h5 to stop that but that means opening another weakness in kingside. 27...Qg5 28.f6 h5 29.Nh2 gxf6 [29...g6 30.Qc3 Ne6 31.Qe1 build on pressure and then play g4.] 30.Rcf2 f5 [30...Ne6] 31.Bxf5 Nxf5 32.Rxf5 Qg6 33.Qc2 [33.Rf6 Stop pawn move to isolate all black pieces from kingside] 33...Ne6 34.Nf3?! [34.Qe2 Ng7 35.Rf6 Qh7 (35...Qb1 36.Nb2 Qh7 37.Nd3) 36.Qf3 Rf8 37.Qg3 Re7 38.Nf3] 34...Rf8 35.Ne5 Qh7 36.Qe2 Ng7 37.Rf6 Ne8 38.R6f4 Bc8 39.Rh4 [39.Nc3 Idea is to activate the Knight or open another front 39...f5 40.e4 dxe4 41.Nxe4+/-] 39...Ng7



40.g4? [40.Rf6 Be6 41.Nc3; 40.Rf6 Same concept. Keep the pwan at f7 so that black can not coordinate his pieces. Even Kh2 was better.] 40...f6



41.Nd3?! [41.Qf2 This prevents fe as Rf8 falls. Also defends the Rh4. Note Ne5 is stopping the Qg6 and Rf7 41...Ne6 42.Nf3 Rg7 43.Kh2 hxg4 44.Rxh7 g3+ 45.Qxg3 Rxg3 May look equal but white can play against the queenside pawns.] 41...Qg6 42.Kh2 hxg4 43.hxg4 Ne6 44.Rh1 Rh7 45.Rxh7 [45.Kg3] 45...Qxh7+ 46.Kg1 Qg6 47.N1f2 Rf7 48.Qf3 Qg7 49.Rh5 Rf8 50.Kg2 Rf7



1/2-1/2
