With all of whites scope why are the percentages so good for black?

Just played this opening as white. Probably my best game ever, sacrificed my queen and rook and mated with 2 knights and a rook. BDG is a great opening imo.

not a very serious opening

I used this variation once as black and I ended up having a very good game. 

interesting

I play the BDG a lot and have never seen black use this varition

gooooo black
