1. c2c3  1... e7e5  2. c3c4  2... g8f6  3. b1c3  3... f8b4  4. h2h4 Carlsen apparently insisted on trying this  one more time! 4... e8g8  5. e2e3  5... c7c6 A classical approach by a classical player. 6. g2g4  OK, now it starts to make sense. Carlsen is fighting for the center the  way people do it in the Reti opening. And the way another great  Scandinavian, Bent Larsen, loved to do with the g-pawn. 6... d7d5 A  central break against the g-pawn thrust. 7. g4g5  7... f6e8  8. a2a3  8... b4e7  9. c4d5  9... c6d5  10. d2d4 The world champion does not allow d5-d4. 10... e5d4  11. e3d4  11... b8c6  12. f1g2  12... e8c7 Very solid play by the Russian GM. 13. g1e2
