This simple opening moves the knight's pawn out of the way, allowing White to fianchetto quickly. Although Larsen was successful many times using this technique, the opening proved to be helpless during the 1970 USSR vs. Rest of the World match against Boris Spassky.


The most common response for Black is 1. ... e5, which cuts off the bishop's scope.
