1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. f1b5 A solid variation, which objectively is as good as opening the Sicilian with 3.d4 but which leads to more strategic positions. 3... b8d7 A popular option and the best to play for a win. 3...Bd7 is good but gives less chance of imbalance. 3...Nc6 is also playable but inferior to the other two moves. 4. e1g1  4... a7a6  5. b5d3  5... g7g6 This move doesn't immediately fight White's plan to advance the pawns in the center. 6. c2c3  6... f8g7  7. d3c2  7... g8f6
