The Najdorf Sicilian, which arises after 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 has been and continues to be a tremendously popular opening at all levels. It is sharp, unbalanced, with many theory-laden lines - and fun. The main lines after 6 Bg5 e6 7 f4 are steeped in theory, making them tricky to play, especially for players with limited time to study.
