1. g1f3  1... d7d5  2. g2g3  2... b8d7  3. d2d4  3... d7b6 A strategically creative system: the b6-square is not the knight's natural habitat. The advantage is that it's more difficult for White to play the pawn to c4. 4. f1g2  4... c8f5  5. b2b3 [%c_effect b3;square;b3;type;Interesting;persistent;true] Not so much to fianchetto the bishop, but rather to play c4. 5... e7e6  6. e1g1  6... h7h6  7. c2c4  7... c7c6  8. b1d2 I don't really like this square for the knight, I think it could go to c3, either now or after c5. 8... g8f6  9. c1b2  9... f8e7  10. e2e3 A thematic move, making way for the queen on e2. 10... e8g8  11. d1e2  11... a7a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] Advancing the pawn to a4 is a good plan that shows the advantage of the knight on b6 and the disadvantage of the knight on d2. 12. f3e5  12... b6d7  13. e5d3 A new move. 13... a5a4 A natural continuation. 13...Ne4 and 13...Qb3 are good options, with equality in both cases. 14. f1c1  14... d8b6  15. c4c5  15... b6a6  16. g2f1  16... b7b5 [%c_effect b5;square;b5;type;Mistake;persistent;true] This is a clear positional mistake. Black shouldn't close the queenside. 17. f2f3 Now White can prepare to advance in the center without any major worries. 17... a4b3  18. a2b3  18... a6b7  19. e3e4  19... f5h7  20. e4e5 White has achieved a clear advantage. 20... f6e8  21. a1a8  21... b7a8  22. c1a1  22... a8b7  23. b3b4  23... g7g5 [%c_effect g5;square;g5;type;Interesting;persistent;true] A difficult move, as it creates more weaknesses, but Black tries to generate some activity. 24. d2b3  24... e8g7  25. b3a5 The knight on a5 fulfills an important function, pinning Black to the defense of the c6-pawn. It can come back when needed.
