The Exchange Variation is the most challenging and aggressive way for white to fight the hypermodern Grünfeld.
It is the most common move and could be considered the main line. It’s also the most thematic in that it features all of the main themes of the defense. Those are:
White’s broad center: white has a c3, d4, e4 center which helps control five key squares on the board.
Black trying to destroy the center – black is going to employ all of his forces to put pressure on d4 and to try and break open white’s center.
The pawn majorities – white will most often have pawns on e4 and d4, black on a7 and b7. Those are their strengths for the endgame. Each side will try to utilize their majority and create a passed pawn. White has the additional advantage of being able to control central squares and gain tempi on black’s pieces with his two central pawns.
The c4 square – a major weakness in white’s position. It can no longer be defended by a pawn (unless a piece trade happens on b3, which black won’t do). It is a perfect outpost for black’s pieces and play often revolves around it. Usually black’s plan of occupying it will be Nc6-a5-c4.
The Excnhage Grünfeld is very heavy in theory. There are numerous lines you have to know very deep in order to play the opening correctly. The easiest way to start playing it is to learn the main plans and patterns in the opening. Learn where each piece goes and what the plan with that piece is. Learn the ideas and what white and black want to do. That way not knowing the exact move order won’t mean as much.
