1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. e2e3  4... e8g8  5. g1f3  5... b4c3  6. b2c3  6... d7d6  7. f1d3  7... e6e5 So employs a rare system, which was played against him by Aronian this year in a blitz game. 8. e3e4  8... f8e8  9. e1g1  9... e5d4 Boldly accepting the sacrificed pawn, but we are still in both players' prep. 10. c3d4  10... f6e4  11. f1e1  11... e4f6  12. e1e8  12... d8e8  13. h2h3 This seems like a slow move, but it's important to prevent the development of the black bishop. 13... b8d7  14. d1c2 A new move. White has excellent compensation, with the bishop pair pointing toward the black king and all his pieces in the game. The computer finds resources for Black to maintain balance, but I think most chess players would choose White here. 14... b7b6 A natural move to finish development. 15. c1b2  15... c8b7  16. d4d5  16... e8f8  17. g2g4 White needs to create an attack on the kingside. I love moves that advance pawns in front of the king (when they are good). 17... h7h6  18. g1h2 The critical moment of the game. 18... c7c6 This move loses. Black has two acceptable alternatives. 19. g4g5  19... h6g5  20. f3g5 Now the attack is too strong. 20... c6d5  21. d3h7 Robson develops the initiative with enviable precision. 21... g8h8  22. h7f5  22... d7e5  23. f2f4  23... e5g6  24. b2f6  24... g7f6  25. g5f7
