1. c2c4  1... e7e5  2. b1c3  2... g8f6  3. g2g3  3... f8b4 A curious thematic match. The Rossolimo  line was discussed disregarding the color. 4. e2e4  4... b4c3  5. b2c3  5... e8g8  6. f2f3 Amazing how fresh these positions are. This is a  novelty! 6... b7b5 And a bold sacrifice in return! 7. d2d4 Long-term factors before everything. Notice how again Carlsen has  only pawns moving, but the presence of his bishop pair makes the dynamic  risk worth it. 7... e5d4  8. c3d4  8... b5c4  9. e4e5 An important move to win a couple of tempos for the  development and stabilize the center. 9... f6d5  10. f1c4  10... c8b7  11. g1h3 The best square for the knight. 11... d7d6  12. e1g1 Now Carlsen misses a chance to use the bishops effectively. 12... b8d7
