csmath: 6. d4?! 8. Bf1?!
[Yet another strange opening by Rapport. The whole opening does not make any sense at all.]
After 12 moves white is already on defensive.
13. ...Nc8?!
15. ...Nxe3
[Nakamura will not miss a chance to play tactical game.]
16. Qe2?
[Of course it is hard to admit that bishop on f1 needs to be moved to e2 but that is needed:
16. fxe3 Qh4, 17. Kf2 d5, 18. Be2 Bd6, 19. Nf1 Ne7, 20. Qe1!
and even on defensive white's position is not shaky here.]
19. Qf3?
[19. Qc2 d5, 20. Bd3 dxe4, 21. Bxe4 and black will play with pawn up although white can now develop faster.
However playing this would amount to admitting that his whole opening was lousy and Rapport will rather lose that do that.]
29. d5?!
[29. ...Bh6 is clearly stronger.]
30. Rh5? Bg6
and white loses at least an exchange.

This game is below standards for Wijk An Zee, in particular Rapport's play.
