The main line of the Orthodox Variation, when Black plays 5… h6, is covered in our Lines 259-264, while this opening line deals with the alternatives.
After the quite common 5… O-O 6. e3 Nbd7, White has a choice between the Botvinnik Variation (8. Bd3), Rauser Variation (8. Qb3), and the following three popular options – 7. Rc1, 7. Qc2 and 7. cxd5. In most of these lines, Black’s best reaction is to transpose to the corresponding lines with h7-h6, since otherwise White gets slightly better prospects.
[Diagram: White to Move] Black is behind in development and his King is weakened. White Rook on h1 is the only inactive piece, so White plays an unexpected maneuver to launch a decisive attack!
