Know the classics

In yesterdays post I mentioned the game Selzniev v Alekhine from 1921, which contained a similar idea to Anand's exchange sacrifice against Carlsen. This game was used as an example of the exchange sacrifice in  Euwe's and Kramer's "The Middle Game Volume 1". Annotating the game, the authors said the sacrifice (20 ... Rb4) was perfectly sound as in return for the material lost Black has (a) A protected passed pawn, (b) the two bishops, (c) White's weak a and c pawns as targets and (d) the c5 square. Alekhine himself thought this was in fact worth more than the exchange.
Nonetheless it took quite a while for Alekhine to covert his position into a winning one. He had to trade one advantage (position) for another (material), but in doing so he was able to retain enough of an edge to eventually wear his opponent down.
