If 9. Bc4 Bd7, if 9. 0-0-0 I like d5, if 9. g4 nd7
I once played Golubev in an ICC qualifier, he played a very nice KID and scored a pretty win...
9.Bc4 main line, Bd7 is the main response. down this line is everything I've said about weaker white pawn endings.
9.o-o-o 'the other big group', black gets to play d5 immediately, and the normal 'mate or be mated' ensues, with much weaker king attack for white. if it goes to engame, the white kingside is usually vulnerable again. but so is black queenside, unlike in the mainline. in fact, perhaps white pawn endings are even better here usually? but the king attack is seldom a problem, which imo makes 9.o-o-o lines much less challenging for black than mainlines.
9.g4 I don't know these lines very well (not that I knew the others especially well either). the g4 lines after o-o-o have some crazy looking positions for black, which still hold (until a better endgame). if there's some specific points related to g4
before castling, I wouldn't know.
but I'd assume uncastled white has a big chance of getting caught with his pants down, and black might even get away with crazy stuff because of that. and lets face it, what do dragon players love more that trying out crazy stuff? that list is very short.
that said, 9.g4 Nd7 looks very odd to me. what are you gonna do after the white pawns crash through and you'd need something to cover h7 from the h-file battery? you probably won't be able to accept the h-pawn sac either?
oh, just looked at the db, and saw 9.g4 is that strange looking Be6 Nxe6 fxe6 line doubling the e-pawns. right. well, never played it, have no idea. but I think I remember seeing topalalov play it some years ago, and if memory serves the commentators said it was fine?
