1.g4? {Basman's trade mark! Commentary by Colum, with computer analysis added by Ed -hindsight is always 20/20.} b6 {The computer's opening book suggests d5 and e5 as being the most popular responses.}
2.Bg2 Nc6 3.b4 Bb7 4.c4 e6 5.a3 h5
6.gxh5 Qg5 7.Bf3 Qh4
8.d3 {If 8.Bg2, black has gained a tempo. However, if the Bishop does not move, the Night has no squares to go to. White is already in a mess.} Nf6
9.Nc3 Ng4 10.Ne4 Nd4 11.Bg5 Qxh5
12.Bf4 Nxf3+ {The computer suggests e5 is better, followed by 13.Bd2 Qh4 14.Ng3 Bxf3 15.Nxf3 Qh3 16.Nxd4 Qg2 17.Rf1 exd4.} 13.Nxf3 e5
14.Bd2 Qh3 {Black seems to have an advantage, but White's next few moves look threatening. There does not appear to be a clear way forward for Black. Computer: Qg6 is better followed by 15.Qb1 f5 16. Neg5 Be7 17.Rg1 Bxg5 18.Nxg5 Nxh2.}
15.Qc2 {Computer: Rg1 is better because...} f6 {Computer: Bxe4 is followed by 16.dxe4 Qg2 17.O-O-O Nxf2.}
16.c5 Bc6 17.cxb6 cxb6
18.Qb3 Qh5 {The King-side attack is going nowhere, so a change of plan.
Maybe White's opening was better than I realised. His position in the centre looks very solid. Computer: This retreating of the Queen levels White's chances.}
19.Rc1 Qf7 20.Qc2 Be7 21.h4 Nh6 22.Rg1 Nf5
23.a4? Nxh4 {No reason not to take the Pawn.}
24.Nxh4 Rxh4
25.b5 Bxe4 {Forced. If Bb7, Qc7 or if Bd5, Qc8+ followed by Nd6 and White wins!}
26.dxe4 Bc5
27.Qd3 Qg6? {If Rxg6, Rh1# and mate, but this seems inferior to g5 consolidating the extra Pawn.}
28.Kf1 Qxe4 29.Qxe4 Rxe4
30.Rxg7 O-O-O {Computer: Rxa4 is better followed by 31.Rg8+ Bf8.} 31.a5 Kb8
32.Rf7 Rh8 {The White Rook cannot take both Pawns, so Black can leave another Pawn en pris.}
33.e3? {White should play axb6 to prevent Black from obtaining a passed Pawn.} Rh1+
34.Ke2 Rxc1 35.Bxc1 bxa5 36.Rxf6 d6 37.Kd3 Rb4
38.Bd2 Ra4 {If Rxb5, Kc4. Computer: e4+ leads to 39.Ke2 Rb2 40.Kd1 a4.}
39.f4 e4+
40.Kc2 {Computer: Ke2 is better followed by Bb4, 41.Bxb4...} Ra2+ {Computer: Ra3 is better followed by 41.Kd1 a4.}
41.Kd1 a4
42.f5? {Computer: Significant error, Re6 is much better.} a3 {Threatening Rxd2 followed by a2 and a1=Q.}
43.Bc3 Kb7 44.Re6 Rf2 45.f6 Kb6 46.Rxe4 Kxb5 47.Rf4 Rxf4 48.exf4 d5

55.Kc1 Ke3 56.Kd1 a4 57.Kc1 Bf8 58.Kc2 Bh6 59.Kd1 Ke4 60.Ke2 a2
61.Kd1 Kd3 62.Ke1 Ke4
63.Kd1 Ke5 {Computer: Better is Ke3 followed by 64.Kc2 a3 65.Kd1 Kd3 66.Ke1 Kc2. 67.Bxd4 Kb1 8.f8=Q Bxf8 69.Kd1 a1=Q 70.Bxa1 Kxa1 71.Kc1 Bb4 72.f7 Ka2 73.f8=Q Bxf8 74.Kc2 Bg7 75.Kd3 Kb3 and Black wins.}
64.Ke2? {Don't see a win for Black after Kc2. Computer: Possible but not easy...
