As I had noticed many times before, the relations between bishops g2/b7 and b2/g7 are always in favour of the kingside bishops. Wondering why it is has always been felt like that, I realized that it wasn't a mere feeling but an objective fact, as the kingside bishop is usually protected by the king after castling, which is an important detail.  -  Anish Giri

The future belongs to he who has the bishops. - Siegbert Tarrasch
