Grunfeld Defense

The Grunfeld Defense (1.d4 Nf6 2.c4 g6 3.Nc3 d5) is a hypermodern opening where Black immediately challenges White's center. Instead of building a pawn center, Black aims to destroy White's center and dominate with pieces.

About the Grunfeld Defense

The Grunfeld was invented by Ernst Grunfeld in 1922 and has become one of the most important defenses in chess. After 3...d5 4.cxd5 Nxd5, White gets a big center with e4, but Black plans to undermine it with ...c5, ...Bg7, and piece pressure. The Exchange Variation (4.cxd5 Nxd5 5.e4) is the main line, leading to one of the most deeply analyzed positions in chess. Kasparov used it extensively in his World Championship matches.
