In this game Andruet battles Spassky on level terms until move 27 when he makes an fatal mistake. Spassky's reply leaves him with a won position, but it also contains a deadly threat involving a Queen sacrifice.
The game features a minority attack and there is a good explanation of the possibilities inherent in this formation HERE.
I first became interested in the minority attack with white after seeing a couple of nice wins by Reshevsky and about the same time reading about it in Pachman's Modern Chess Strategy. It seemed like the ideal positional approach, simple and straight forward. Unfortunately, in practice black has plenty of satisfactory ways of meeting it and at best white doesn't get more than a draw.
