Look at these sacrifices!!

6. Bf4, doesn't look good, wrapping the bishop among it's army,
but.. After all, you did a solid attack after Black castled long, keep it up!

@SaNyob Bf4 does look awkward. I am not looking at stockfish so I don't know what it says, but often with the closed center like this, the bishop actually really enjoys that square. He is a great defensive and glueing piece.
