Grunfeld Defense Counterthrust Variation (1.d4 Nf6 2.c4 g6 3.g3 Bg7 4.Bg2 d5) Chess Puzzles

The “Grunfeld Defense Counterthrust Variation” is a Grunfeld line where Black aims to meet White’s central buildup with a timely pawn counterthrust, most often centered on …c5 (or the related …cxd4 structure) to challenge White’s d4/e4 ambitions. In practice, the defining feature is that Black’s counterplay is not delayed: the pawn break is timed so it hits the center while White is still committing pieces to attack or build a strong pawn chain.
