1. d2d4  1... d7d5  2. g1f3  2... c7c5  3. c2c4  3... c5d4 An interesting position and not well-known at amateur level. It's not easy to demonstrate an advantage for White in this opening. 4. c4d5  4... g8f6  5. f3d4  5... f6d5  6. e2e4  6... d5f6  7. f1b5  7... c8d7  8. b1c3  8... e7e5 The most accurate. 9. b5d7  9... d8d7  10. d4f5  10... d7d1  11. e1d1  11... b8c6  12. c1g5 The most natural attempt. 12... f6g4  13. d1e2  13... f7f6  14. g5h4  14... h7h5  15. f2f3  15... g4h6  16. h4f2 It's good for White to allow the capture on g5, gaining the e4-square. 16... h6f5  17. e4f5 We're not used to seeing Carlsen lose a slightly better endgame, but what can I say $2 There are no supermen. 17... e8c8  18. h1d1  18... d8d1
