I am reading about the Grand Prix Attack and the main lines of development for Black. One line considered is as follows.
[FEN ""] 1. e4 c5 2. Nc3 d6 3. f4 g6 4. Nf3 Bg7 5. Bc4 Nc6 6. O-O
After White castling, I read, Black's best moves are Nf6 or Ne7 after e6.
As a beginner I want to ask, due to the fact that the idea behind the Grand Prix Attack is to attack Black's kingside, is queenside castling a line to consider for Black?
