The Smyslov Variation in chess is a form of the Queen's Gambit Accepted. Smyslov's Variation is inspired by the Gruenfeld Defense but a lot easier to play because there isn't a lot of deep theory to absorb. The basic idea is to establish a safe castled position and aim to undermine White's center with an eventual ...e5 or play on the queenside, using knights to infiltrate the light squares. Smyslov's preferred plan is to bring the Nf6 to the queenside via d7, bring the bishop to g4 to eliminate the Nf3, and then play ...e5.
