Vienna System

The Vienna System is a method used in chess to evaluate and compare different opening moves based on established theory and strategic principles. Developed at the Vienna Chess Congress of 1922, it provides a standardized framework for classifying openings, focusing on move sequences, pawn structures, and piece development. This system helps players understand which openings are solid, aggressive, or flexible, guiding decision-making during the opening phase of the game. In essence, it serves as a reference tool for players and analysts to identify and study common opening strategies efficiently.
