Blitz game over on Lichess  in the Anonymous section.

 The Fish  gives at best a .5 advantage to White with best play.  That said, I think there are several advantage over The Colle-Koltanowski old Nc6 main lines.   A) avoids of the pitfalls White suffers playing 9.e4.   (Stats for White are poor in the old Nc6 main lines )  B) the Koltanowski-Rudel Attack  IMO is more complex, offer more scope. C) Black,  if not familiar with the attack, often plays in the same format of the old Nc6 main lines with 9.e4... and often runs afoul real quick. 

 For me it makes the Colle-Koltanowski once again playable.
