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
