1.f4 d5 2.Nf3 c5 3.g3 Nc6 4.Bg2 e6 5.O-O Nf6 6.b3 Be7 7.Bb2 O-O 8.d3 Ng4!? 9.Bc1 Bf6 10.c3 Qa5? {a bad idea} 11.h3! Bxc3?? {A complete blackout and loosing a piece.} 12.Nxc3 Qxc3 13.Bd2 {When I took the c3-pawn, I was obsessed by the idea that black was forced to play Rb1, thereby overlooking Bd2, which wins a tempo as well as my knight. Inexplicably, I played Bxc3 after a long thought, never even contemplating Bd2! Black has no compensation whatsoever...} Qf6 14.hxg4 Qe7 15.e3 Bd7 16.a3 f6 17.Rb1 e5 18.f5 Rad8 19.b4 e4 20.Nh4 Qe5 21.Kf2 c4 22.dxc4 dxc4 23.Qc2! {Winning a pawn} b5 24.Bxe4 Rfe8 25.Bd5+?? {Blundering a piece. Thus far, Harrison had made sensible moves and was clearly heading for a deserved win.Sadly, white's position is now lost.} Qxd5 26.Ng2 Ne5 27.e4? Nd3+ 28.Kg1 Qxe4 29.Be3 Bc6 30.Bxa7 Qxg4 31.Rf2 {Black's threat was 31..Re2 Instead of Rf2, also 31.Bf2, Re2; 32.Qd1, Qf3 would not have saved white.} Nxf2 32.Bxf2 Be4 33.Qb2 Bxb1 34.Ne3 {After 34.Qxb1.. would have followed 35...Rd1.} Qe4 35.Kh2 Bd3 36.Qc1 Qf3 37.Qg1 Be4 38.g4 Rd2 39.Nd1 Rxd1 40.Qxd1 Qxd1? {Qg2 checkmate instead would have been quicker} 41.Bg3 Qh1#
