Najdorf Sicilian: 1.e4 c5 2.Nf3......... Nbd7
Najdorf Sicilian: 1.e4 c5 2.Nf3...... Nbd7
TL;DR
Opposite-side castling with both sides racing pawn storms: White's g4-h4 campaign hunts the black king, while ...b5 and ...Nb6 swarm the queenside. Both kings live in danger from move ten onward, and concrete preparation matters more than principles.
