The Yerevan System arises from the Sicilian Defense and is characterized by White's solid pawn structure and piece development. The early moves 1.e4 c5 2.Nf3 a6 3.Bc3 aim to control the center while preparing for potential pawn advances with d4. This setup appeals to strategic players who prefer a flexible, less theoretical approach, allowing for gradual buildup and tactical opportunities while avoiding the complexities of sharper Sicilian lines. Typical plans involve developing the minor pieces harmoniously, aiming for central control, and creating chances for a kingside attack.
