=French Defence, Winawer Variation= Although castling to that side where White wants to attack seems to be dangerous for Black, there are no immediate mating threats - at least as long White's Queen is attacking Black's kingside on her own and without support from other pieces. That's why White usually decides to develop some additional pieces which may help with White's kingside attack. Typically this is done by playing 8. Nf3 or 8. Bd3, on rare occasions 8. h4 has also been tried. Note that 8. Bh6 is harmless for Black, who can defend against 9. Qxg7 mate by playing 8... Nf5 or 8... Ng6, in both cases white's queen bishop must retreat and White wasted a tempo.
