Either consciously or unconsciously, chess players continuously assess the importance of time, space, and force. The relative importance of each of the elements shifts frequently throughout the contest, and it’s vital to factor this into our analysis. In this opening, White trades off the permanent weakening of his pawn structure for long term pressure against the dark squares. This theme of weak dark squares consistently presents itself throughout the contest. It colors every single variation and it is the dominant theme in this game. A large number of grandmaster games involve dominating squares of one color. In chess terminology, this is called “working a color complex” and you’ll often see grandmasters orchestrate numerous maneuvers through a color complex on their journey to victory.
