English Opening Anglo Grunfeld Defense Clearance in Chess

In the English Opening Anglo Grunfeld Defense Clearance motif, Black uses a clearance move to remove a piece that blocks a key line—most often to free the dark-squared bishop or open the c- or d-file for counterplay. In this family, the defining feature is the Anglo structure (often with pawns on c4 and e4) combined with a Grunfeld-style fianchetto/dark-square pressure, where one tactical “unblocking” move changes the whole position.
