the exchange of the dark-squared bishops is normally in Black's favour,
leaving White weak on the datrk squares and with a basd light-squared bishops.
The only (fairly rare) exception is if the position offers White serious
attacking chances against the black king.} Kxg7 14. b3 a5 {A normal move for
Black in such positions, securing the c5-square for the black knight.} 15. g3
Nc5 16. Bg2 e5 {A surprising move if you are not familiar with such positions.
Following the exchange of the dark-squared bishops, Black is able to reduce
his space disadvantage in the centre without making any of his pieces bad. The
weakness of the backward d6-pawn is not a serious problem, while his bishop
stands ready to exchange off the white knight if it advances to d5, leaving
Black with a favourable knight vs. bad bishop scenario.} 17. f4 f6 18. f5 g5

the Maroczy structure.}) 0-1
