1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. c2c3  4... g8f6  5. d2d4 The good old classical  line that So already used to beat the world champion earlier this year. 5... e5d4  6. e4e5  6... d7d5  7. c4b5  7... f6e4  8. c3d4  8... c5b6  9. b1c3  9... e8g8  10. c1e3  10... c8g4 The  pawn structure now is very much like the one in the Yates variation of the Ruy Lopez. White has a strong center, but Black's free piece play allows  him a chance to eventually attack and destroy the center. 11. h2h3  11... g4h5  12. a1c1 So deviates from the move that brought him success earlier, and  chooses a promising side line which he obviously analyzed extensively as  well. 12... b6a5 Carlsen bets on the \"outpost play.\" In the meantime,  he frees himself from the passive bishop. 13. e1g1  13... a5c3  14. b2c3  14... c6a5 That was the idea. The knight is about to step  on the c4-square. In hindsight, this seems slow though. 15. g2g4 So's plan is clear: he needs to bring his huge kingside mass  into motion. 15... h5g6  16. f3e1 The f-pawn is unleashed. 16... f7f6  17. f2f3  17... c7c6  18. b5d3  18... e4g5  19. d3g6 A very strong move. The tripled pawns  will be huge targets. 19... h7g6  20. e3g5  20... f6g5  21. d1d3  21... a5c4 Carlsen decided to sacrifice a  pawn. 22. d3g6  22... d8e7  23. f1f2 So is accurate as usual. 23... c6c5 The only counterplay, albeit slow. 24. e1g2  24... a8c8  25. c1f1  25... c5d4  26. c3d4  26... c8c6  27. g6d3  27... c6a6 Now it all ends quickly. 28. f3f4  28... a6a3  29. d3g6  29... a3h3  30. f4f5  30... g8h8  31. f5f6 Well calculated as usual. 31... g7f6  32. e5f6
