i deleted the following if white plays or f black can win a pawn for example nxe nxe d or f qb after bb black can try to put pressure on the defenders of d because it s completely crap after nxe is the best move but as it was correctly seen by others that s not winning a pawn in any line it s just an equalizer regarding f the article is a little bit less wrong f is bad for white after qb but still not losing a pawn by force and the sentence regarding pressure on the defenders of d does not make any sense at all of course d is an important square in all dragon systems but you don t put pressure on the nc or the bb sometimes rarely in the line that we see here you kick it away with b b b if white permits that sometimes you sacrifice the exchange with rxc but you never put pressure on it you don t put pressure on minor and major pieces in general unless they are in a bind or otherwise immobilized
