Sep-12-16 | | Marmot PFL: White goes wrong with a badly timed 12 e4 13 d5 and never recovers. Possibly Nakamura just wanted to complicate and force a mistake, but black never made that mistake. |

Sep-12-16 | | Calli: 15...d4! shows the White's scheme to be faulty i.e., if 16.Rxd4 Qb6 holds the pawn. |

Sep-12-16 | | patzer2: Instead of the <badly timed> 12. e4 =, the computers slightly prefer 12. f4 a4 f5 (12...Qd7 13. e4 = to ) = to (0.24 @ 24 depth, Komodo 10) After 15. Rfd1?, allowing 15...d4 (-0.98 @ 26 depth, Stockfish 6), the game turns strongly in Black's favor. Instead, 15. exd5 c3 16. Qxc3 Bd5 = (0.00 @ 33 depth, Stockfish 7) would have kept it level. Black, however, did not fully exploit the advantage. So later in the game 21...d3 =, instead of 21...Qc7 to , gave White a missed opportunity for a defensible position with 22. e5 Rc7 23. Bxc6 = to (-0.24 @ 21 depth, Komodo 10). Perhaps 23.Rb6?, allowing 23...Nd4 (-1.65 @ 28 depth, Komodo 10.1), was the final decisive mistake. The computer alternative 23. Bf1 Bg4 24. Rdc1 Nd4 (-0.71 @ 20 depth) leaves White with an ugly position, but a Super GM like Nakamura might have been able to hold it. |

Sep-12-16 | | patzer2: <Chesstorian72> Nakamura just got caught off guard in the opening with a questionable 12. e4?! and a weak 15. Rfd1? Opening errors happen to the very best players, even world champions. Such mistakes are not typical of Nakamura's play, as his 2789 rating and number 6 world ranking attest. |

Sep-12-16 | | SirRuthless: Was Hikaru smoking some grass before this game? What a disaster. Yeah it happens to everyone but he could have groveled for a draw instead of putting the team in jeopardy. Good clean game for black. This is probably going to be the highlight of his career so small consolation for the Georgian I guess. |

Sep-13-16 | | patzer2: Perhaps 12. e4 wasn't so questionable afterall. The computers give 12. e4
(0.00 @ 29 depth, Stockfish 7) as equal. According to the Opening Explorer 12. e4 was played three times previously with a win for White in Timman vs E Scholl, 1969, a draw in Stein vs Benko, 1962 and a loss in Andrew Jonathan Whiteley. However, what does not appear in the opening explorer is Black's solid reply 12...dxc4 =. It's a computer first choice, but may not have been played previously. So I wonder if this didn't involve a little opening preparation on Black's part, involving springing a small novelty with 12...dxc4 = in the hope Nakamura would become overly aggressive in trying to refute it. |

Sep-13-16 | | patzer2: The previous loss in the OE after 12. e4 was in A J Whiteley vs A Ledger, 1994. |

Sep-13-16 | | patzer2: <SirRuthless: Was Hikaru smoking some grass before this game? What a disaster.> I think Nakamura simply got surprised by the strong 15...d4!, which creates great difficulty for White. With 15. Rd1? White appeared to set a pin that put Black under pressure. However, after 15...d4! Black turns the tables. If White tries 16. Rxd4? and captures the poisoned pawn, then 16. Qb3 to sets a pin that puts White under near decisive pressure. |
