This is a subtle move that delays the development of the knight, and the rook on a7 fulfills its function by defending the c7-pawn and freeing the a8-square for the queen, which will be useful after Nbd7. 11. a2a4 Black will quickly get a great position, so possibly this move is not the most accurate. 11... b5b4  12. d2g5  12... b8d7  13. b1d2  13... d8a8 [%c_effect a8;square;a8;type;GreatFind;persistent;true] This is one of the ideas of 10...Ra7. The queen goes to a8, and the other rook can come to c8, supporting the thematic c7-c5 advance. 14. f3e1 [%c_effect e1;square;e1;type;Inaccuracy;persistent;true] A new move. 14... b7g2  15. e1g2  15... c7c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] Black's position is already more comfortable.
