Adorjan Defense

After 1. c4 g6 2. e4, Black plays 2...e5 and stops the e-pawn from advancing further, while 1...g6 prepares ...Bg7 to bear on the long diagonal. The structure turns on the d4 and d5 squares. The line is rarely seen. 3. Nc3 is the most common reply and White scores well with it. 3. d3 and 3. Nf3 are the other options, and Black has done well against 3. Nf3. Engines rate the position as roughly balanced.
