1. e2e4  1... c7c5  2. g1f3  2... e7e6  3. g2g3 White can build an entire repertoire with Anti-Sicilians alone and still fight for an advantage in the opening. Against 2...d6 or 2...Nc6 one of the main alternatives is to place the bishop on b5, and against 2...e6 White can try the move played of the game, fianchettoing the bishop (suggested by Wesley So in his Chessable course), but he can also play 3.d3 (King's Indian Attack) or 3.c3, with a version of the Alapin in which Black has slightly fewer possibilities than normal. Even 3.b3 is a possible try. 3... b8c6  4. f1g2  4... g8f6  5. d1e2  5... d7d6  6. e1g1  6... f8e7  7. c2c3  7... e6e5  8. f1d1 The most critical idea: White aims for a quick d2-d4. 8... e8g8  9. d2d4  9... c5d4  10. c3d4
