After 15 ...g6 the comments in the book are as follows" "By relinquiishing a third pawn Lasker hopes to use the semi-open g-file for defence. If instead 15...g5 White tightens the grip over the e5-square with 16 f4!, after which it is extremely difficult to see what black can do to prevent White's steamroller of an attack. 16...gxf4 17 gxf4 Bd7 18 g4 looks totally grim, so Black should try to block the gam up with 16...g4. Nevertheless, following 14 Ne2 the analysis is overwhelmingly in White's favor."
