It's a solid line whose main variations leads to an endgame that is hard to break. Every now and then, however, the Berlin and its associates are defeated. 6. d1d4  6... e6d5  7. e2e4  7... d5e4  8. d4d8  8... e8d8  9. f3g5  9... c8e6  10. c1d2 A rare move. 10... b8d7  11. c3e4  11... f6e4  12. g5e4  12... h7h6 This move prepares f7-f5, driving the knight out of its great position. The plan, however, weakens the black position. 13. d2c3  13... a8c8  14. f1d3  14... f7f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] The best chance. The king is heading to f7. 15. e1g1  15... d8e8 White's position looks very promising, but apparently Black can defend. Carlsen tries an interesting plan. 16. d3e2 [%c_effect e2;square;e2;type;Interesting;persistent;true] 16... e8f7  17. f2f4 The critical position of the game. Black needs to find a very precise move. 17... f8c5 [%c_effect c5;square;c5;type;Mistake;persistent;true] This grants White the pair of bishops and a safe advantage. 18. e4c5  18... c8c5  19. a1d1 [%c_effect d1;square;d1;type;Inaccuracy;persistent;true] 19... d7b6  20. c3d4  20... c5a5 [%c_effect a5;square;a5;type;Inaccuracy;persistent;true] 21. b2b4  21... a5d5  22. e2f3  22... d5b5 [%c_effect b5;square;b5;type;Mistake;persistent;true] 23. d4c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] The rook is trapped. 23... b6a4  24. f3e2  24... b5c5  25. b4c5  25... a4c3  26. e2h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] 26... g7g6
