His annotations frequently contain glaring errors and his attacks weren't always sound, but who cares? Humans can't calculate like Stockfish; they make mistakes in their calculations, they suffer from fatigue, etc.
When reading old chess books, which often have mistakes in analysis, the important thing to remember is that the general principles they contain can be of great value to the practical player.
The following game was played in a 1st category tournament in Moscow in October. In December Alekhine scored another triumph when he cleaned house in the Moscow City Championship with a score of 11.5-0.5!
This game demonstrates the importance of the Pawn center and how an attack can develop from it. In the complications Alekhine reached a position where his superiority was evident: he controlled the center and his opponent's pieces were all huddled together trying to defend his King. Then he made a tactical error! Not one that lost the game, but one that should have allowed Zubarev to at least equalize...but he, also, missed the correct continuation and Alekhine finished him off with a couple of crushing blows.
