In the above game, didn't it look like White had the weaker position until the last 5 moves?
Does anyone really think they can maneuver the the white pieces like the game above? I am quite confident I cannot.
I'm fairly certain that White was playing a Reversed Chigorin system, not a London, per se, and Black was actually "playing as White." There's a chapter in Kovacevic's London System book which bears this out.
So I rest my case regarding the usefulness of playing "reversed systems," because that's what both GMs were doing in the above game. Double reversal. Ha!
And is there any practical lesson in that blizzard of middlegame complications? GMs play great chess, with either color, and we don't. 
Reversed Systems are a perfectly legitimate way of saving lots of opening prep time with the white pieces. On balance, you have to "get good" with the black pieces first, in order to win games and get stronger. Use this fact when it comes to starting your white repetoire. Simple.
And you can always add to your white repetoire at a later date.
