1. e2e4  1... c7c5  2. b1c3  2... d7d6  3. g1f3  3... g8f6  4. h2h3 An interesting way to fight the  Najdorf. 4... g7g6  5. d2d4  5... c5d4  6. f3d4  6... f8g7  7. g2g3  7... b8c6  8. c1e3  8... e8g8  9. f1g2  9... c6d4  10. e3d4  10... c8e6  11. e1g1  11... a7a6  12. f1e1  12... a8c8  13. c3d5  13... e6d5  14. e4d5  14... f6d7 A novelty. However, at this stage of the game it seems  as Black is already doing not that well. 15. d4g7  15... g8g7  16. c2c3 The backward pawn on e7 is a big issue and White is  pretty much better all over the place. In the center he has the more  active pieces, he has pawn majority on the queenside, but the real problem is the weak black king. 16... f8e8  17. d1d4  17... g7g8  18. e1e2  18... d8b6 If Black  can only trade the ueens off this will make his life so much easier as he  would be able to defend the e7 weakness with the king. 19. d4h4 But  this is not going to happen. 19... d7e5 The knight is not stable here  and will be soon chased away thus providing time for the White's kingside  assault. 20. g1h2 Nakamura slowly prepares for the opening of the kingside. 20... g8g7  21. a1d1  21... c8c4  22. h4g5  22... h7h6  23. g5d2  23... c4c7  24. d1e1  24... b6b5  25. f2f4 All is ready for the decisive kingside action. 25... e5c4
