1. g3 d5 2. Bg2 e5 3. d4 e4 4. e3 Nf6 5. Ne2 c6 6. O-O Bg4 7. b3?

Bg4 invited White to play h3 with perhaps a small advantage. This move is questionable though. fianchettoing both bishops is destined to positionally fail. It is better to have a good and a bad bishop than to have two mediocre ones. 7. ... Na6 I decide here to just develop and to do it in such a way that I can support the d-pawn with the knight by Nc7 if necessary. 8. Bb2 Qd7 With not much to do but develop it is easy for me to find the right plan. The idea? Prevent h3 and start a great offensive against the White king. According to Vladimir Vukovic in his landmark work "Art of Attack in Chess" you need three pieces to assail a castled king. 9. a3 Qf5 10. Qd2?? This move is the decisive error but it is difficult to see that leaving the pin and playing something like c4 is the way to go. My opponent was the third junior player I had played in a row and they tell them to avoid pins like the plague so this mistake is understandable. 10. ... Bf3 11. c4 h5 12. Qc2 Bxg2 13. Kxg2 h4 14. Rh1 I really thought Ng1 was the better defensive move. hxg3 15. fxg3 

15. ... Qf3+ Here I miss the destructive Ng4! When White cannot defend against both Qf2# and Nxe3+ 16. Kg1 Ng4 17. Nf4 Nxe3 18. Qe2 Qxe2 19. Nxe2 dxc4 20. bxc4 Nxc4 21. Bc1 f5 22. Kf2 Nc7 23. Nf4 Kf7 24. Nc3 Rd8 25. Nce2 Nb5 26. Be3 Bxa3 0-1
