| Jul-01-19 | | Dave12: I don't fully understand what happened here.
It seems that Naka planned a very nice tactical sequence with 17..Nd4 but failed to see the move 24.Bxg7. |

| Jul-01-19 | | Eyal: <It seems that Naka planned a very nice tactical sequence with 17..Nd4 but failed to see the move 24.Bxg7.> According to what Carlsen told Maurice Ashley in the post-game interview (based on a short conversation the players had after the game), what Nakamura missed when he played 21...Rec8?? was the possibility of 22...Bxb3 23.Nd5! with an attack on both black bishops; after 22.Qb2! Black was completely busted in any case. According to engine analysis, 17...Nd4 wasn't such a great idea for Black in the first place because down the forcing line that follows 21.Qe2! should give White a significant advantage. Instead, after Carlsen's 21.Rd3, 21...Bf6! more or less equalizes (though the position remains complicated) - but Rec8, as mentioned, was a losing blunder. |

| Jul-01-19 | | thegoodanarchist: < Eyal: ... - but Rec8, as mentioned, was a losing blunder.> It's difficult to foresee that it loses. Obviously, since a world-class GM didn't see it. But it does leave Black's dark-square bishop unprotected, and "LPDO" - loose pieces drop off. No matter what, this was a fun fun fun game to play through! |

|
| Jul-02-19 | | csmath: Having a dozen pieces all in the tactics is really hard to see all and control all. One really has to be very, very concentrated. This position after 22 moves looks like a good homework to study, it is one awful mess on the board. |

| Jul-02-19 | | patzer2: Instead of 17...Nd4? 18. Bxd4! +- (+0.83 @ 25 ply, Stockfish 9) with a strong White initiative, 17...Qc7 = (+0.08 @ 31 ply, Stockfish 9) appears to equalize. |
|
| Jul-02-19 | | patzer2: <Eyal> is correct! Instead of 21...Rec8? 22. Qb2 ± (+1.19 @ 33 ply, Stockfish 9 analysis of move 22...?) with a strong White advantage, 21...Bf6! = (+0.07 @ 31 ply, Stockfish 9 analysis of move 21...?) equalizes. |
|
| Jul-02-19 | | beenthere240: I fail to see that 17...Nd4 is a blunder. Against most players (and many GMs) it might very well win. The opportunity to play 17...Qe7 is not what draws people to chess. |
|
| Jul-02-19 | | patzer2: <beenthere240> I'd say 17...Nd4? 18. Bxd4! ± is a mistake, but not a blunder like 17...a6?? 18. Qb3 +-. The reason 17...Nd4? is a mistake, albeit a high level mistake for a Super GM attempting to win or draw against Carlsen, is White gains a significant advantage after 18. Bxd4! Rxc4 19. Bxe5 Ba4 20. b3 Nxe4 21. Qe2! ± (+1.20 @ 18 ply, Stockfish 9 analysis of move 21...?). In the actual game, Carlsen let Nakamura off the hook with 21. Rd3? which allows 21...Bf6 =. Nakamura's likely decisive mistake, as noted by <Eyal>, was playing 21...Rec8? (instead of 21...Bf6! =) which allows 22. Qb2! ± (+1.19 @ 33 ply, Stockfish 9 analysis of move 22...?). |

| Jul-02-19 | | Ulhumbrus: If the advance 16 e4 counts as a threat one alternative to 15...Rac8 is 15...Rfd8 so that on 16 e4 Be8 clears d7 for the N on f6 without disconnecting the rooks |
