Basic position of the Kopec system

Template: checkerboard / maintenance / new

The Kopec system ( ECO code B50) is created in the Sicilian Defense after moves 1. e2 – e4 c7 – c5 2. Ng1 – f3 d7 – d6 through 3. Bf1 – d3 !? . The last train was by the American chess player and computer science - Professor IM Danny Kopec proposed (1954-2016). This results in the position shown in the diagram.

At first glance, the position of the bishop on d3 appears to be disadvantageous because it blocks your own d-pawn. However, White intends to move the bishop to c2 with 4. c2 – c3 and 5. Bd3 – c2, followed by the center advance 6. d2 – d4.

It is also possible to do the 2nd Bf1 – d3! to play as a key move (ECO code B20), followed by 3. Ng1 – f3 with move change to the main variant of the Kopec system.
