The alternatives also lead to an advantage. 10... c7a6 The knight returns in order to go to b4. 11. d5e6 [%c_effect e6;square;e6;type;GreatFind;persistent;true] An excellent moment to change the pawn structure. 11... c8e6  12. c1f4  12... f6e8 A sad move, but the d6-pawn requires protection. 13. d1d2 White has a clear advantage, but what is most important in a blitz game $2 Her moves are natural and easy. The pawn on d6 is a weakness; White has a space advantage and a nice square for the knight on d5. 13... a6b4  14. a1d1  14... d8b6  15. f4h6 [%c_effect h6;square;h6;type;GreatFind;persistent;true] The dark-squared bishop is Black's best piece, and it makes sense to exchange it. 15... b4c6  16. h6g7
