Well, Black commits positional suicide with 9...Nd7 and 10 ...f5, it makes no sense. He gives up the strong square e5 to White for free, also taking on a weak and backward pawn e6 on an open file. It the meantime he only buries his Bc8 deeper.
It's as if he just thrust his hand into his own chest and pulled out his still-beating heart to give to you, so to speak.
That is very dramatic way of putting forth a point although I agree with your observation
This is a opening which takes the best out of colle and bird system
I have given a game with annotation to play this opening
This opening bring the best out of two world positional play and tactical king side attack,if our tactical king side attack fails our positional play will save the day.
