1. d2d4  1... g8f6  2. g1f3  2... d7d5  3. c2c3  3... c7c6  4. d1c2 A curious little move that Nihal has played before. The idea is to avoid the development of Black's bishop on f5. 4... g7g6 Preparing the to develop the bishop on f5 anyway. The problem is that Black's dark-squared bishop won't be so well placed on g7. To be honest, developing the light-squared bishop to f5 is not such a great idea either since there's a pawn on g6. That said, the move is still perfectly playable. 5. c1f4  5... f8g7
