1.e4 e6 2.d4 d5 3.e5 (defining the 'Advance Variation' of the French Defense. Not the most ambitious line for White, but an understandable choice against such a strong opponent.)3...c5 4.c3 Nc6 5.Nf3 Bd7 6.Be2 Nge7 7.O-O Nf5 8.Be3?! (the main line here is 8.Bd3 and after 8...cxd4 9.Bxf5 exf5 10.Nxd4 Be7 11.Re1 0-0 12.Qd3=. In this position as white, Shirov played 8.Na3 cxd4 9.cxd4 Bxa3 10.bxa3=) 8...Qb6 9.Qd2 Nxe3 10.fxe3 Be7 11.Bd3 O-O 12.Kh1? (Completing development of the queenside with 12.Na3 f6 13.exf6 Bxf6 14.Nc2 was in order. The text is preparation for the White's next and more serious mistake) 12...f6 (13.e4?? a tactical oversight) cxd4 14.exd5 Nxe5 15.Nxe5 fxe5 16.Re1 exd5 17.Rxe5 Qf6 18.Re1 Bd6 19.cxd4 Qh4 20.g3 Bxg3 0-1
