Grunfeld Defense Counterthrust Variation Fork in Chess

In the Grunfeld Defense Counterthrust Variation, the “fork” motif appears when Black’s counterplay creates a tactical moment where one move attacks two valuable targets at once. A defining feature is the counterthrust against White’s center (often with …c5) that opens lines and lets a piece jump with tempo, typically forking a king and a major piece or forking two pieces. The result is a tactical swing: the side executing the fork gains material or forces concessions.
