The queenless game that can arise from the opposing 8.Qb3 Qb6 line results an an approximately equal game with the emphasis on quiet maneuvering. 

Black tried a bit too hard to mix things up in the feature game which allowed GM Vorobiov,E to demonstrate some fine endgame play.

Here is the feature game.
