The Najdorf delays the b8-knight so Black can read White's sixth move before choosing a center. Learn when ...e5 should drive the d4-knight, when ...e6 should hold a compact shell, how the Poisoned Pawn queen escapes the b-file, and why Black's queenside race must begin before White opens the kingside.
Work through seven Black routes and three White routes across the Bg5 main line, Poisoned Pawn, English Attack, Opocensky, Sozin, 6.f3, and 6.f4. Each route explains the plan for the side you are training.

Verified source trail: every sequence and legal choice comes from the Sicilian Najdorf guide, its position bank, and the four seeded book branches. The five preserved guide tests resolve with ...Qa3 (-0.08), ...Nbd7 (-0.07), g4 (+0.59), ...b3 (+0.63), and ...Nbd7 (+0.14).
The 23 boards cover the 5...a6 tabiya, both central structures, the queen fork on b6, the Poisoned Pawn escape, long-castling races, the Sozin diagonal, the ...d5 break, and the f4 queen trade. Every Learn route owns at least two drills, and all five published tests retain their exact setup and answer.

Choose one of six verified starts and set the opponent from 600 to 2500. Ten coach triggers recognize the tabiya, the b6 fork, the rook attack on the queen, both central breaks, the Opocensky shell, long castling, and the advanced ...b3 race.
The playable set contains the exact 5...a6 base, verbatim seeds for 6.Bg5, the Poisoned Pawn, 6.Be3, and 6.Be2, plus the no-book 17...b3 test board. Every White target has a board-checkable Black complement.
