1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. d2d4  3... c5d4  4. f3d4  4... e7e5 A risky variation that shows that Nakamura was willing to play for the win with Black. This choice certainly surprised his opponent, who was probably expecting the Berlin. 5. d4b5  5... d7d6  6. b1c3  6... a7a6  7. b5a3  7... c8e6  8. a3c4  8... a8b8 This mysterious move is a specialty of GM Maghsoodloo. I won't pretend to understand the idea. Let's say it's a kind of super protection to play b7-b5 at some point. 9. c3d5  9... e6d5  10. e4d5  10... c6e7  11. g2g3  11... b7b5  12. c4e3  12... g7g6  13. a2a4  13... g8f6  14. a4b5  14... a6b5  15. f1g2  15... f8h6  16. e1g1  16... e8g8  17. d1d3  17... f6d7 With the knight going to c5 and the pawns on the kingside ready to roll, Black has a fine position. 18. c1d2  18... d7c5  19. d3e2  19... d8c7  20. b2b4 A natural move, but placing the bishop on this square is also interesting. 20... c5d7  21. a1a5  21... h6e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] A very difficult move to make; after all, exchanging this dark-squared bishop is a pain in the chest. Now we have a nice fight between a pair of bishops and a pair of knights. The capture is necessary for the black knights to start jumping. 22. d2e3  22... e7f5 This is the point. 23. a5a7  23... b8b7  24. a7b7  24... c7b7  25. e3d2  25... f8a8  26. e2d3  26... a8a2  27. f1d1  27... d7f6  28. d2g5  28... g8g7  29. g2h3 Both players demonstrate their high class. The position remains balanced. 29... f5d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] Nakamura takes his knight on a strange journey. 30. c2c3  30... d4c2 [%c_effect c2;square;c2;type;GreatFind;persistent;true] The knight appears to be in danger, but it prepares to go to c4. Another route is also possible, as we will see shortly. 31. d3f3  31... f6g8 [%c_effect g8;square;g8;type;GreatFind;persistent;true] Remember this move. 32. h3f1  32... a2a3 [%c_effect a3;square;a3;type;Interesting;persistent;true] Instead of taking the knight to c4, Nakamura decides to create the tactical threat of capturing on b4. His pieces are clumsy on the queenside, but his calculation skill is so great that everything works. 33. g5c1  33... a3b3  34. f3e4 [%c_effect e4;square;e4;type;Inaccuracy;persistent;true] White's problems will begin now. 34... b3c3  35. c1b2  35... g8f6  36. e4h4 [%c_effect h4;square;h4;type;Mistake;persistent;true] 36... c3b3 [%c_effect b3;square;b3;type;Inaccuracy;persistent;true] 37. b2c1  37... f6g8 [%c_effect g8;square;g8;type;GreatFind;persistent;true] Again the Ng8 move. Black's king is well protected. 38. h4d8  38... b7e7  39. d8a5  39... c2d4  40. c1e3  40... d4f3  41. g1g2  41... e7f6  42. f1e2  42... e5e4  43. a5b5  43... f6b2 [%c_effect b2;square;b2;type;Mistake;persistent;true] 44. b5a6 [%c_effect a6;square;a6;type;Mistake;persistent;true] 44... g8f6  45. h2h3  45... h7h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] The pawn goes to h4, helping the attack. 46. g2f1  46... b2e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] 47. f1g2  47... b3e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] A nice finish. 48. f2e3  48... h5h4
