Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. h3 { is a multi purpose move. First of all it prepares g4. But more importantly it covers the g4 square which discourages black moves like Ng4. } 6... g6 { The Dragondorf have gotten a poor reputation the last years. However, here white already has played the slow h3. } 7. g3 { white prepares to fianchetto his light squared bishop. } 7... Nc6 8. Be3 { if white had forgot to play h3 earlier black could have simply responded Ng4, harassing whites bishop. } 8... Bg7 9. Bg2 O-O 10. O-O Nd7 11. b3 { this move might seem a bit odd as it opens the a1-h8 diagonal, giving the g7 bishop more squares and target. Whites simple idea is to take control over the c4 square. This makes black moves such as Ne5 useless, as white can simply play f4 and force the knight back. } 11... Nxd4 12. Bxd4 Bxd4 13. Qxd4 b6 14. Nd5 Bb7 15. c4 e5! (15...
