Grünfeld Defense: Three Knights Variation, Petrosian System

Key moves: 1.d4 Nf6 2.c4 g6 3.Nc3 d5

The Grünfeld Defence is a hypermodern opening where Black allows White to build a big pawn centre, then attacks it with pieces and the ...c5 break. The central tension creates exciting, tactical positions.

History & Notable Players

Introduced by Ernst Grünfeld in 1922. It became a world-class weapon through Vasily Smyslov and Bobby Fischer, and was later used extensively by Garry Kasparov in his World Championship matches.
