At one point it was one of Magnus Carlsen's favorite defenses. 10. d2d4  10... b8d7  11. b1d2  11... c8b7  12. b3c2  12... f8e8  13. d2f1  13... e7f8  14. f1g3  14... a6a5 A very rare plan. The overwhelming majority of games continue with 14...g6. Black advances the pawn to a4, gaining some space and preventing White from playing the typical a2-a4. 15. c1d2  15... a5a4  16. c2d3  16... c7c6  17. d1c2  17... d8b6  18. d2e3  18... b6a5  19. e3d2  19... a5b6  20. a1d1 This natural move is a novelty, but now Black is able to solve the opening problems. 20... c6c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] 21. d4e5 It's always a difficult decision for White in the Ruy Lopez, whether to play d5 or to take the e5-pawn. 21... d7e5  22. f3e5  22... d6e5  23. c3c4  23... b5b4  24. g3f5  24... b6c6 A good move to prevent Ne3. 25. d2g5  25... f6h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] 26. g2g3 [%c_effect g3;square;g3;type;Inaccuracy;persistent;true] 26... c6g6 [%c_effect g6;square;g6;type;Inaccuracy;persistent;true] The queen is not well-placed here. 27. c2c1  27... h7h6  28. g5e3  28... h5f6  29. f2f3  29... f6h5  30. g1h2  30... g6f6  31. e1f1  31... e8d8 The big question is whether White will be able to place the knight on the ideal d5-square. 32. c1d2  32... a4a3  33. b2b3  33... d8d7  34. e3g1  34... a8d8  35. d2e2  35... d8e8 [%c_effect e8;square;e8;type;Mistake;persistent;true] After this Caruana places the knight on the dream square and Abdusattorov is never back in the game. 36. f5e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] 36... g7g6  37. e3d5  37... f6d8  38. g1e3 [%c_highlight d5;keyPressed;none;opacity;0.8;square;d5;persistent;false] This is a positional tragedy for Black. If the knight is captured then White captures with the c-pawn and works on the c-file to capture Black's pawn on c5. Furthermore, the bishop gains the c4-square and it's possible to play on the kingside with the f4 break. 38... g8h7  39. e2f2  39... d8a5  40. d3c2  40... b7c6  41. d1d2  41... c6d5  42. c4d5  42... f8d6  43. c2d3  43... d7c7  44. d2c2  44... h5f6  45. f1c1  45... e8c8  46. f2d2 It's one-way traffic now. 46... d6f8  47. d2e2  47... f6e8  48. f3f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] Black's position can no longer be sustained. 48... f8g7  49. e2f2  49... e8d6  50. c2c5
