1. d2d4  1... g7g6  2. e2e4  2... f8g7  3. g1f3  3... d7d6  4. c2c3 A very solid system. 4... g8f6  5. f1d3  5... e8g8  6. e1g1  6... c7c5  7. h2h3  7... d8c7  8. f1e1  8... e7e5  9. c1e3 Another solid move. 9... b7b6  10. b1d2  10... b8c6  11. a1c1  11... f8e8  12. d4d5 This is a very good moment to block the center, right after the  black rook has abandoned the f-file. Thus, the usual kingside counterplay  f7-f5 will start a couple of tempi later, and this will have an enormous  impact on the game. 12... c6e7  13. b2b4 Aronian's playground is on the  queenside. 13... f6d7 Naturally preparing the f7-f5 advance. 14. d2f1  A modest but excellent move. Aronian, however, only saw the hidden point  later. 14... c5c4
