The Sicilian Defense: Sveshnikov Variation arises after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 and falls under ECO code B33. Named after Latvian GM Evgeny Sveshnikov, this variation features the ambitious 5...e5, which gives Black the desirable Najdorf-style pawn structure without immediately committing to ...d6 and blocking in the dark-squared bishop. Black's strategy is to delay ...d6 long enough for the bishop to develop actively to b4, effectively reaching an enhanced version of the Najdorf. To prevent this, White's key response is Ndb5, which practically compels ...d6 by threatening to occupy the d6 outpost with check. While this knight jump forks Black's king and c8 bishop, the threat is easily manageable after ...Bxd6. With 3.9 million Lichess games across all rating levels, it is a well-established opening choice.
