This game shows how important it is to be prepared for unorthodox variations of well-known openings. Particularly this is important in the most widely played opening in this era, the Sicilian. <1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e6> Switching from the Najdorf to the Scheveningen variation <7.Be2 Be7 8.O-O O-O 9.f4 Qc7 10.Qd3?!> The first moves were well-known in theory, but 10.Qd3?! is completely new to me. This move makes some sense too. 10.Qd3 supports White's advanced pawns and puts more pressure on b5 (as we will see later on, White could have profited from that). The book moves here, however, are 10.a4, 10.Qe1, 10.Bf3, the risky 10.g4?! and the waiting move 10.Kh1. Personally I think I like 10.Bf3 and 10.Kh1 most. <10...Nbd7!?> Not bad, but more normal is 10...Nc6 <11.Bf3 b5?> A poor move, exposing the rook on a8 via 12.e5 dxe5 13.Bxa8. <12.e5 Nc5?> Trying to grab the initiative by attacking the queen, but this move clearly does not work. Black's reply here could have been 13.Ndxb5! axb5 14.Nxb5 Nxd3 15.Nxc7 and now two of Black's pieces are under attack at the same time (the knight on f6 and the rook on a8). <13.Qe2?> White fails to seize the opportunity. <13...Nd5> The best move (or should I say least worst?) under the current situation. Still it loses a pawn and Black's position is abominable. <14.Bxd5 exd5 15.Nxd5 Qd8??> A blunder that loses the game immediately. The only right move here to stay in the game would have been 15...Qb7. <16.Nc6 Qd7 17.Ncxe7+> Black resigns. 1-0
