1. d2d4  1... g8f6  2. c1g5  2... e7e6  3. e2e4  3... h7h6  4. g5f6  4... d8f6  5. c2c3  5... d7d5  6. f1d3  6... c7c5  7. g1f3  7... c5d4  8. c3d4  8... d5e4  9. d3e4  9... f8e7 A solid developing  move. The position is very much like a French Rubinstein variation. 10. b1c3  10... e8g8  11. e1g1  11... b8c6  12. e4c6 Now we are in Panov-Attack Caro-Kann  waters. This idea has been used by the 12th world champion Anatoly Karpov  before. As long as White manages to keep the light-squared bishop locked,  he should not worry it. The problem is that his opponent is often  determined to get rid of the pawn, even for free. 12... b7c6  13. a1c1  13... f6f5  14. f1e1  14... f8d8  15. e1e5  15... f5g6  16. d1e2  16... e7f6  17. e5e4 Missing his last chance. 17... c8b7 Now c6-c5 is unstoppable. 18. e4f4  18... c6c5 Once that the second bishop is open, Nakamura will have a  strong initiative. 19. d4c5  19... a8c8  20. c3a4  20... e6e5 This pawn is moving with  tempo. 21. f4b4  21... b7c6 And there are also problems with the loose white  pieces.
