Improve Your Chess: First Learn End! - Botvinnik-Alekhine 1938

Alekhine makes an inaccuracy in the opening and Botvinnik obtains the kind of position where only he has play.  He trades off into a superior endgame with excellent winning chances. Alekhine continues to have little play and Botvinnik slowly and surely takes advantage of his plusses to build a winning position. Unlike some of the other endgames in this series where the winner was not much ahead going into the endgame, this one is a good example of "endgame technique" from a winning position.
