GAME 004 - Edward Davies vs Martin Newbury 2007



1.e4 c5 2.Nc3 e6 Signifies the French Defence setup by black. This doesn't appeal to all sicilian players, but is considered a solid reply to 2.Nc3. 3.g3 d5 4.exd5 [4.d3 is a tame alternative for white, e.g. Weide-Van der Werf, Netherlands Ch, Leeuwarden 2001 : 4...Nf6 5.Bg2 dxe4 6.dxe4 Qxd1+ 7.Nxd1] 4...exd5 5.Bg2 In Fritz's opening book, this was the only move played (occuring 12 times). [Gary Lane recommends: 5.d4 e.g. 5...cxd4 6.Qxd4 Nf6 7.Bg5 Be7 8.Bb5+ Nc6 9.Bxf6 Bxf6 10.Qc5 Bxc3+ 11.bxc3 Qe7+ 12.Qxe7+ Kxe7 13.0–0–0 Be6 14.Ne2 Kd6 15.Rhe1 Kc5 16.c4 dxc4 17.Bxc6 bxc6 18.Nf4 Bg4 19.Re5+ Kb4 20.Rd4 Be6 21.a3+ Kxa3 22.Nxe6 Kb4 (22...fxe6 23.Rxc4 a5 24.Re3+ Ka2 25.Ra4#) 23.Rc5 1–0 ; Lane-Nunn , Stroud 1980] 5...Nf6 6.h3?! The first questionable move. Fritz gives this a moderate warning light. I wanted to control the g4 square completely, preventing for example a g1–f3 knight from being pinned by Bg4, and meaning the pin break attempt h3 cannot be met with Bh5, where I really do not want to consider g4. I believe 6.h3 has some potential even though it is a little risky and anti-principal in not developing a piece or lines for pieces. There are three moves in Fritz's book: [6.d3 e.g.: 6...d4 7.Ne4 Nxe4 8.Bxe4 Nd7 9.Ne2 Nf6 10.Bg2 Bd6 11.0–0 0–0 12.Nf4 Re8 black is a bit better; 6.d4 e.g.: 6...cxd4 7.Qxd4 Nc6 8.Qd1 d4 9.Nce2 Bc5 10.Nf3 Bf5 11.0–0 0–0 12.Nf4 Re8 13.Nd3 Bb6 14.Bg5 h6 15.Bxf6 Qxf6 16.Nd2 black was better; 6.Nge2 e.g.: 6...Nc6 7.d4 cxd4 8.Nxd4 Bb4 9.0–0 0–0 10.Bg5 Bxc3 11.bxc3 h6 12.Bf4 Ne4 13.Nb5 Bf5 14.Nc7 g5 15.Qxd5 Qxd5 16.Nxd5 Kg7 17.Bc1 white did better] 6...Be7 [F1: 6...d4 7.Ne4 d3 8.cxd3 Nc6 9.Qe2 Be6 10.Nf3 Nxe4 11.dxe4 Be7 12.b3 0–0 13.Bb2 Qd7 Fritz puts black being slightly better] 7.Nge2 0–0 solid play, but fritz again think black can gain a small advantage with more dynamic play: [7...d4 8.Ne4 Nxe4 9.Bxe4 0–0 10.0–0 Re8 (10...Bxh3 very complicated line and also good for black 11.Re1 (11.Bxb7 Nd7 (11...Bxf1 12.Bxa8 Nd7 (12...Bxe2 13.Qxe2 –0.3) 13.Be4 Bxe2 14.Qxe2 Nf6 15.Bg2 Bd6 16.d3 Re8 17.Qf1 Qd7 18.Bd2 –0.3 I like the control white has of the h1–a8 diagonal.) 12.Re1 Bg4 13.f3 (13.Bxa8? this makes black's attack on the light squares around the white king far too strong 13...Qxa8 14.d3 Ne5 -5.96 ... e.g.: 15.Rf1 Nf3+ 16.Kh1 (16.Kg2?? Ne1+ 17.Kh2 Qg2#) 16...Re8 17.c4 Bf6 18.Nf4 Re1 19.Qxe1 (19.Rxe1 Nxe1+ 20.Kg1 Bxd1 0–1) 19...Nxe1+ 0–1) 13...Rb8 14.Be4 Nf6 15.Bxh7+ Kxh7 16.fxg4 Nxg4 17.Nf4 Nf6 –0.5 This position hardly looks inspirational for white.) 11...Bg4 12.Bxb7 Nd7 13.f3 Rb8 14.Be4 Bd6 –0.52) 11.Nf4 Nd7 12.Re1 Bd6 13.d3 Nf6 14.Bg2 Rxe1+ 15.Qxe1 Qd7 16.Qe2 Rb8 17.Bd2 = I think 10...Bxh3 was more interesting for black.] 8.d4 cxd4 9.Nxd4 Nc6 10.Be3 All fritz's first moves from both sides. 10...Be6 This is maybe a bit of a tame move. [F1: 10...Bb4 11.0–0 Bxc3 12.bxc3 Re8 13.Re1 Nxd4 14.Qxd4 (14.cxd4 Be6 15.Bg5 h6 16.Bf4 Qd7 17.Kh2 –0.27) 14...Be6 15.Rad1 Qa5 16.a3 Bf5 (16...Qxa3 17.c4 dxc4 18.Bxb7 Rab8 19.Bc6 Rec8 20.Bf4 Rb6 =) 17.c4 dxc4 18.Qxc4 Rac8 19.Qb4 Qxb4 20.axb4 b6 21.Ra1 Re7 22.Bd4 Rxe1+ 23.Rxe1 Rxc2 24.Re7 –0.3] 11.Qd2 apparently not the strongest [F1: 11.0–0 Rc8 12.Qd3 Nxd4 13.Bxd4 0.3] 11...Qa5 [F1: 11...Rc8 ] 12.Nce2 [F1: 12.0–0 Bb4 13.Nb3 Bxc3 14.Nxa5 Bxd2 15.Bxd2 Rfe8 =] 12...Qxd2+ 13.Bxd2 Ne5?! Fritz doesn't like this move [F1 13...Bd7 14.0–0 Rae8 15.Rfe1 Bc5 16.Be3 0.3] 14.Nf4 [or 14.0–0–0 Nc4 15.Bg5 h6 16.Bf4 Bc5 17.b3 Nd6 18.Be5 Nfe4 19.Bxd6 Bxd6 20.Bxe4 dxe4 21.Nxe6 Ba3+ 22.Kd2 fxe6 23.Ke3 Bc5+ 24.Kxe4 Rxf2 25.Rhe1 Raf8 =] 14...Bd6 Fritz doesn't like this and gives the medium warning light [14...Ne4 15.Be3 Rae8 0.7] 15.Nfxe6 fxe6 16.0–0? = This is incorrect according to Fritz. Long castling was the way. [16.0–0–0 0.89 16...Rae8 17.Rhe1 Bc5 18.Bc3 Nc6 19.Rxe6 Ne4 (19...Rxe6? 20.Nxe6 Bxf2 21.Nxf8 d4 22.Nxh7 Kxh7 23.Bxc6 dxc3 24.Bxb7 cxb2+ 25.Kxb2 Bxg3 white is easily winning; 19...Bxd4 20.Rxe8 Rxe8 21.Bxd4 Nxd4 22.Rxd4 Re2 23.Bxd5+ Nxd5 24.Rxd5 2.19) 20.Rxe8 Rxe8 21.Nf5 g6 22.Nh6+ Kf8 23.Ng4 d4 24.Bd2 Nxd2 25.Kxd2 Kg7 white is a clear pawn up + -] 16...Nc4 17.Bg5 Kf7 [= 17...Rae8 ] 18.Rfe1 [18.b3 Nb6 (18...Ne5 19.Bf4 Rac8 20.Rae1 Nfd7 21.Be3 Bb4 22.f4 Nc6 (22...Bxe1?? 23.fxe5+ Kg6 24.Rxe1) 23.Nxc6 bxc6 24.Rd1) 19.Rae1 Rae8 20.Nb5 Nc8 21.c4 Bb4 22.Rc1 1.00] 18...Rfe8? Definitely inaccurate [18...Be5 19.c3 Bxd4 20.cxd4 Rac8 21.b3 Nd6 22.Bf4 0.19] 19.Rab1? = it was correct to dislodge the knight [19.b3 Na3 20.Rac1 Bc5 21.Nf3 Kg8 22.Ne5 0.80] 19...Nb6? Bad. Changes the evaluation from 0.00 to 0.88 [19...h6 20.Bc1 =] 20.Bxf6? = , incorrect, again changing evaluation back to zero [20.Nb5! nice positional move 20...Nc4 21.b3 a6 22.bxc4 axb5 23.Rxb5 Kg6 1.50] 20...gxf6?? Wow. An unexpected blunder! [20...Kxf6 of course] 21.Nb5 [21.Bf3! brilliant move if you can find it. Threatening Bh5+ winning exchange, King must move from defence of e6 pawn, which both it and rook are needed for. 21...Kg6 (21...Kf8 22.Rxe6; 21...Ke7 22.Rxe6+) 22.Rxe6] 21...Bb8 22.b3 a6 23.Nd4 Be5 24.Ne2 [24.Rbd1; 24.c3] 24...Rac8 25.c4 Rc7 26.f4 A little suboptimal, but not too bad. [F1: 26.a4 a5 =] 26...Bd6 approx –0.29. Here, due to confusion over the time control, my flag dropped without me even knowing about it. I was playing well against this far higher rated opponent, so that tought me the importance of being aware exactly of the time control and clock situation before starting.
