1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. d2d3  5... d7d6  6. c2c4 One of many possible variations for White on the Ruy Lopez with an early d3. 6... c8g4  7. h2h3  7... g4f3  8. d1f3  8... f6d7  9. c1e3  9... f8e7  10. b1c3  10... d7f8 A move that seems quite logical, taking the knight to e6. However, this position is yet another case that when in doubt, castling is best. 11. c3e2 [%c_effect e2;square;e2;type;GreatFind;persistent;true] A strong new move, almost certainly discovered by Nakamura over the board and not as a result of home preparation. White is ready to play d3-d4 and will get a comfortable advantage. 11... f8e6  12. d3d4  12... e5d4  13. e2d4  13... e6d4  14. e3d4  14... e8g8  15. a4c6  15... b7c6  16. a1d1 White's advantage is not decisive, far from it, but it's the kind of position that grandmasters love. A pressure \"for free\" without risks. The worst that can happen, if Black defends very well, is a draw. Based on this, we can say that the opening was a success for Nakamura. The advantage is due to what will be the main strategic theme throughout the game: pawn structure. For now, White has a space advantage and a more compact structure with only two islands. 16... f8e8  17. e1g1  17... e7f6 During my analysis I looked for alternatives, but it's very likely that Sevian's move is really the best. 18. c4c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] More accurate than the immediate exchange on f6. 18... e8e6  19. d4f6  19... d8f6  20. f3f6  20... g7f6 [%c_effect f6;square;f6;type;Inaccuracy;persistent;true] This one I really don't like, although I'm certainly biased by what will happen later in the game. 21. f2f3  21... a8b8  22. f1f2  22... b8b5 [%c_effect b5;square;b5;type;Mistake;persistent;true] The situation gets more serious after this mistake. Better chances are given by 23. f2c2 [%c_effect c2;square;c2;type;GreatFind;persistent;true] 23... d6c5  24. d1d7  24... e6d6  25. d7c7 With such a horrible pawn structure, I think it's safe to say that Black is already lost.
