[ Notes by grandmaster Ian Rogers ]

1.Nf3 Nf6 2.c4 g6 3.g3 Bg7 4.Bg2 d5 5.cxd5 Nxd5 6.0-0 Nb6 7.Nc3 0-0 8.d4 Nc6 9.d5 Na5 10.e4 c6   Black has lured White's pawns forward in order to undermine them with this move. However Davidovic is ready with a well prepared pawn sacrifice. 11.Bf4! cxd5 12.exd5 Bxc3!?

[ Three rounds earlier at the Olympiad the Turkmenistani master Simonenko had tried 12...Nac4 against Davidovic but after 13.Qe2 Bg4 14.h3 Bxf3 15.Bxf3 Rc8 16.Rac1 Qd7 17.Bg4 f5 18.Bf3 Nxb2!? 19.Qxb2 Bxc3 20.Rxc3! Na4 21.Rxc8! Nxb2 22.Rc7 Qd8 White could have crowned his queen sacrifice by playing 23.d6!! with a decisive attack. The game was ultimately drawn.]

13.bxc3 Nxd5 14.Bh6 Re8 15.Qd4! Nf6 16.Qh4 Nc6 17.Rfe1 Bg4 18.Nd4! Rc8 19.Bg5   The pressure against Black's position is becoming unbearable so he tries for relief by returning his extra pawn. 19...Nxd4 20.cxd4 Qd7 21.Bxf6 exf6 22.Qxf6 Re6?! 23.Qf4 Bh3? 24.Bxh3! Rxe1+ 25.Rxe1 Qxh3 26.Re7   Black had believed this move to be impossible, forgetting that White's queen prevented 26...Rc1+. Now, forced into complete passivity, Black can do nothing to prevent the advance of White's passed d pawn.   26...Rf8 27.d5 Qc8 28.h4 b5 29.d6 Qc5 30.Qf6 a5 31.d7 Qd5 32.Qe5! Qd1+ 33.Kg2 Qd3 34.Qc5!   The threat of 35.Re8 is unstoppable. A crushing defeat for the Spaniard.   1-0
