It's one of the sidelines they can play along with the Worrall, Anderssen, Tarrasch, and thus avoid the main line 0-0. The Mackenzie variation was named after Scottish-American player George Mackenzie, who popularized it in the nineteenth century. He was undefeated with it, with 17 games and only 6 draws! This is a very unreasonable variation in my opinion. White will have to lose time to recapture the d4 pawn and black will have no issues dealing with white's activity. The reason the entite Mackenzie variation is dubious, is that the pawn cannot be recaptured due to a series of tempi that result in the a4 bishop being trapped. Once the queen is dragged out to d4, we can play c5, with tempo, and then b5 and c4, and the bishop is lost. So white must resort to ways of recapturing the pawn later on. 0:00 Introduction to the Mackenzie and the available resources for further study 03:31 History the Mackenzie Variation 11:39 Strategy and Basics of the Mackenzie Variation 19:45 Theory of the Mackenzie Variation
