The Sicilian – Nimzovich-Rubinstein Variation arises after 1.e4 c5 2.Nf3 Nf6. ECO code: B29.

Black develops the knight immediately, attacking e4. After 3.e5 Nd5, positions somewhat resemble Alekhine\'s Defence's Defence structures. White can also play 3.Nc3, 3.d4, or other moves. The variation is fully playable and has a solid theoretical reputation.
