1.e4 c6 2.d4 d5 3.e5 Bf5 4.f4 slightly unusual/rare move 4...e6 5.Nf3 Nd7 this is one of many playable continuations [5...h5; 5...Ne7; 5...Nh6; 5...Qb6; 5...c5] 6.Be2 [last game given in opening book: 6.Be3 Qb6 7.Qc1 c5 8.c3 Nh6 9.Nbd2 Be4 10.Be2 Rc8 11.0–0 Nf5 12.Bf2 cxd4 13.Nxe4 dxe4] 6...c5 fritz gives this the warning light [6...Be7 7.0–0 Nh6 8.h3 Qb6 9.g4 Bg6 10.a4 a5 = , interesting position] 7.c3 [F1: 7.0–0 Qb6 8.a4 a5 9.Bb5 +/=] 7...Ne7? clearly a weak developing move, obstructing the DSBishop and queen until it moves again [7...Nh6 the correct way] 8.0–0 apparently white misses his opportunity to exploit the temporarily badly developed black position [8.dxc5 Nxc5 9.Nd4 a6 10.0–0 Qc7 11.Nd2 Bg6 (11...Ne4? 12.Qa4+ Nc6 13.Nxf5 exf5 14.Nxe4 dxe4 15.Be3 Be7 16.Qb3 b5 17.g4 Na5 18.Qc2 g6 19.Rad1 very unpleasant for black +/-) 12.N2f3 Nf5 13.Nxf5 Bxf5 14.Be3 Rc8 +/-] 8...Nc6 = , black has equalised 9.Be3 Be7 10.a3 fritz doesn't like this [10.Qb3 a6 11.Nbd2 b5] 10...Qb6 11.b4 c4! a tenable option still, but a more experienced player would probably take on b4 'without thinking'. These critical moments in the resolution of pawn structure are the sort of moments that seperate different strengths of players. A strong player will know how to deal with all kinds of pawn pushes and what structures - resolved or unresolved - are the best in practice, and which ones are to be avoided most of the time [11...cxb4 12.axb4 0–0 13.Bd3 Bg6 14.Na3 Rfc8 15.Bxg6 hxg6 =] 12.a4 a6? This one is unjustifiable. More space needs to be contended with a5 [12...a5 13.b5 Nb4! It was probably this point that struck me that a5 was bad, as I assumed I'd have to retreat to a7 for example, and the knight would be out of the game. Fritz plays this beautiful knight sacrifice immediately, completely confident in the compensation given 14.Ne1 (14.cxb4 axb4 15.Nbd2 Qc7 16.Qc1 Rc8 17.Bf2 = , black has full compensation) 14...Bg6 15.Nd2 Qc7 16.Bg4 Nd3 =] 13.Qd2 white should play a5 right away [13.a5 Qd8 14.Na3 0–0 15.Ng5 Rc8 +/=] 13...f6? a serious error according to fritz. [13...a5 14.b5 Nb4 etc] 14.Na3 [the punishing reply was: 14.Nh4 Bxb1 (14...g6 15.a5 Qc7 16.Nxf5 gxf5 17.Bh5+ Kf8 looks hopeless for black +/-; 14...Be4 15.f5 Nd8 16.Bh5+ Nf7 17.Bg4 h5 18.Bh3 Nf8 19.fxe6 Nxe6 20.a5 Qc6 21.Bf5 Bxf5 22.Rxf5 0–0–0 23.Ng6 Rhe8 24.Qf2 the positional pressure keeps piling up +/-) 15.Raxb1 0–0 16.Nf3 Qc7 17.a5 b6 18.axb6 Qxb6 19.f5 Na7 20.Kh1 +/-] 14...Be4? wrong as it allows a relatively brilliant combination 15.Nc2 [15.Nxc4! Qc7 (15...dxc4 16.d5 the point; revealed attack on black queen 16...Qc7 17.d6 Qd8 18.dxe7 Qxe7 19.Bxc4 0–0 20.exf6 gxf6 21.Rad1 Rad8 white is a pawn up with a better position +-) 16.f5 fritz gives crazy continuations like this 16...dxc4 17.fxe6 Nb6 18.exf6 gxf6 19.Bf4 Bd6 =] 15...Qc7 16.Rf2 Qb6 there's no way I was repeating moves to offer a draw, so I obviously had a reason for this at the time. I think with only 1 rook on the back rank, trying to break through with a5 and the queen may be a lot easier. Fritz doesn't mind 16.Qb6 17.Raf1 a reasonable option = 17...f5? very bad according to fritz. black shouldn't allow Ng5 [17...0–0 18.a5 Qc7 19.Nce1 b6 20.axb6 Qxb6 21.Bxc4! Nxb4! (21...dxc4 22.d5 Qb5 23.dxc6 Qxc6 24.Nd4 Qd5 25.f5 Nxe5 26.Nxe6 Rfc8) 22.Be2 (22.cxb4? Bxb4 23.Qa2 dxc4 24.Qxc4 a5 25.exf6 gxf6 26.Nd3 -/+) 22...Nc6 = ... And people deride the Caro-Kann as being quiet and boring?!] 18.Ng5 Dave doesn't miss this 18...Bxg5 19.fxg5 Ne7 [F1: 19...0–0 20.a5 Qc7 21.Bf3 Bxc2 22.Qxc2 b6 23.axb6 Qxb6 24.Qc1 a5 25.bxa5 Qxa5 26.Rb2 Rfb8] 20.Bf3 [F1: 20.Bh5+ Ng6 21.a5 Qc6 22.Be2 b5 23.axb6 a5 24.Ra1 Qxb6 25.Rxa5 Rxa5 26.bxa5 Qxa5 27.Nb4 0–0 28.Rf1 +/-] 20...Bxc2 this may win a pawn, but it isn't the best [F1: 20...a5 21.Bxe4 fxe4 22.Qe2 Nf5 23.b5 0–0–0 gives black a more solid position than in the game] 21.a5! fritz thinks it is better to just take on c2 immediately without this interposition [21.Qxc2 Nxe5 22.Bh5+ N5g6 23.a5 Qc6 24.Re2 b6 25.axb6 Qxb6 26.Qa4+ Qb5 27.Ra2 Qxa4 28.Rxa4 Kd8 29.Rfa1 +/=] 21...Qa7 22.Qxc2 Nxe5 23.Qd2? bad as it allows Nd3 [23.Bh5+ g6 24.Be2 Nf7 +/-] 23...Nd3 24.Re2 Qb8 25.g3 Qd6 26.Rg2? [26.Bf4! Qc6 27.Qe3 Kf7 28.Bc7! Ng6 (28...Qxc7? 29.Qxe6+ Ke8 30.Bxd5 f4 31.Bxc4 Kd8 32.Bxd3 fxg3 33.h4 ++-) 29.Bb6 Rhe8 =] 26...Ng6 27.Be2 0–0 28.Bxd3 cxd3 29.Qxd3 f4 not all that bad, but fritz prefers: [F1: 29...Qc6 e.g. 30.Bf4 b6 31.axb6 Qxb6 32.Re2 a5 33.bxa5 Rxa5 34.Rfe1 Re8 35.Qd2 =] 30.gxf4 Nxf4 31.Bxf4 Rxf4 32.Qe3 [or 32.g6 Rxf1+ 33.Qxf1 hxg6 34.Rxg6 Rf8 =] 32...Rxf1+ [F1: 32...Re4 33.Qh3 Rf8 34.Rgf2 Rxf2 35.Rxf2 Qe7 =] 33.Kxf1 Rf8+ 34.Ke2?! inaccuracy [34.Rf2] 34...Rf4 35.Rf2?? huge blunder 35...Rxf2+?? completely missed it. Even in relative time trouble, in an OTB game this should be easy to pick out at an instant. I was amazed when analysing the game to see we had both overlooked this. [35...Re4 0–1] 36.Qxf2 e5? another appauling oversight [36...Qc7 37.Kd2 =] 37.Qg3! seizing the tactical chance 37...Qg6 38.Qxe5 Qc2+ 39.Kf3 Qxc3+ 40.Kg4 Qc8+ 41.Qf5 Qc6 42.h4 g6 43.Qe5 Qd7+ 44.Kf4 Qf7+ 45.Ke3 Qd7 46.Qb8+ Kg7 47.Qe5+ Kg8 48.Qb8+ Kg7 49.Qe5+ draw
