Yes, it really is that bad for White.
He gets: doubled pawns, targets of his own to defend, an open position while his king still hasn't castled, and ....
Not even a pawn advantage in the long run.
If he refrains, he has a pretty solid center and simple development, which is White's dream in the Grunfeld Exchange Variation.
I figured that, but I was really wondering about if white couldnt managed to hang on to it and then in the end get a material advantage.
I do find it a bit odd that Games Explorer has absolutely no games using 9... Bd7 (assuming I entered it all in right). Are you sure this is the position being discussed?
Yes I am sure. Though he did say that it was an uncommon move to make. More common was Bg4.
. The castling part.
Thanks!
