1. g1f3  1... g8f6  2. b2b3  2... d7d5  3. c1b2  3... c7c5  4. e2e3 For the rapid, Nakamura chose to play the Queen’s Indian Defense with an extra tempo. 4... b8c6  5. d2d4  5... c8g4  6. f1e2  6... e7e6  7. b1d2  7... c5d4  8. e3d4 It is quite tempting to follow a straightforward scheme as early as possible in rapid and blitz and this position is indeed one of those situations. White's plan is clearly to attack the kingside and his moves are more or less the same. It is Mamedyarov who needs to choose a plan in most of cases and this costs him time on the clock. 8... f8e7  9. e1g1  9... e8g8  10. a2a3  10... a8c8  11. h2h3  11... g4h5  12. e2d3  12... e7d6  13. f1e1  13... f8e8  14. g2g4 Kingside expansion. But White is also opening his king, indefinitely. 14... h5g6  15. d3g6 Only this obvious move is a novelty. 15... h7g6  16. f3e5  16... g6g5 Stopping f2-f4. 17. c2c4  17... f6d7 One of the many good ideas. Black does not have to worry about his position; in fact, he is the one who has more clear targets to attack. 18. e5d3 This knight is too good to be traded $1 18... d7f8 And this one is to become even better $1 19. c4c5 Nakamura at least grabs some space on the queenside. 19... d6b8  20. b3b4  20... f8g6  21. d2f3  21... f7f6  22. d1c2  22... g8f7 Both kings are heavily exposed now and one mistake might be the end of the game for either side. 23. e1e2  23... d8c7 Setting up a nice battery. 24. e2e3 Stepping away from the knight fork.The position is extremely tricky and both sides need to be extremely careful, but aggressive too. 24... e8h8 Now Mamedyarov is the first one to get to the opponent's kingside. 25. a1e1  25... f7f8 Stepping away from the checks, but this square is not optimal. 26. c2e2 A tricky resource $1 26... h8h3 It is getting extremely messy. 27. e3e6  27... f8g8 The only move. 28. e6e8  28... g8h7  29. e8e3 A one-move threat. 29... h7g8  30. e3e8  30... g8h7  31. e8e3 And a silent draw offer ... 31... h3h6 ... which is rejected by Mamedyarov $1 32. b4b5  32... c6a5 Missing an almost instant win.
