The Najdorf Variation () of the Sicilian Defence is one of the most respected and deeply studied of all chess openings. ''Modern Chess Openings'' calls it the "Cadillac" or "Rolls Royce" of chess openings. The opening is named after the Polish-Argentine grandmaster Miguel Najdorf. Many players have lived by the Najdorf (notably Bobby Fischer and Garry Kasparov, although Kasparov would often transpose into a Scheveningen). The Najdorf begins: :1. e4 c5 :2. Nf3 d6 :3. d4 cxd4 :4. Nxd4 Nf6 :5. Nc3 a6 Black's 5...a6 aims to deny the b5-square to White's knights and light-square bishop while maintaining flexible development. If Black plays 5...e5?! immediately, then after 6.Bb5+! Bd7 (or 6...Nbd7 7.Nf5) 7.Bxd7+ Nbxd7 8.Nf5 and the knight on f5 is difficult to dislodge without concessions. Black's plan is usually to start a minority attack on the queenside and exert pressure on White's e4-pawn. This is often carried out by means of ...b5, ...Bb7, and placing a knight on c5, or c4 via b6. == Variations == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sicilian Defence, Najdorf Variation」の詳細全文を読む スポンサード リンク
