The Kopec System is an effective sideline against the Sicilian defence. The awkward-looking maneuver of the Kopec bishop(LSB) gives white the chance to build a strong center with e4 and d4.This also prevents complex tactical lines fron black and instead lets white develop a solid position with a Ruy Lopez-like structure.

Just like the King's Indian, Colle and other various opening systems, the Kopec System has a specific position or "setup" that a player should aim for regardless of what his opponent plays.
