context: 1. e2e4 Once again, advancing the king's pawn is the best move. 1.d4 or 1.g3 is also acceptable, but I think the move played is the most accurate. 1... e7e5  2. g2g3 Bringing the bishop into the game. 2... d7d6  3. d2d4  3... e5d4  4. d1d4 There's no knight going to c6 (as would be typical for a queen on d4 in a regular position), but the bishop on h8 is the danger. 4... g8e7  5. f2f4  5... g7g6  6. d4d3  6... f7f5 This allows White to exploit the pin, as Black's queen is unprotected on d8. 7. c1d2 Missing the chance.
