This move, however, is imprecise: the bishop needs to help the white king. 10... b8c6  11. g3e2  11... f8d6 [%c_effect d6;square;d6;type;Inaccuracy;persistent;true] A natural development move but a little slow for what the position asks for. 12. e1g1  12... d8f6  13. f2f3 [%c_effect f3;square;f3;type;GreatFind;persistent;true] An important move, as the f3-square is a weakness that needs to be protected. The best is to place a pawn there. 13... c8d7 Perhaps it would be better to place the bishop on a more active square. In order to achieve this, it's necessary to speed up the Bc7-Qd6 plan. 14. d2d4  14... e8c8  15. c1d2
