 | | Domdaniel: <Eyal> & <CHC> ... This is a beautiful game, and your comments are excellent.
Thanks to both of you. |
|
| Jan-07-17 | | User not found: 19.Qxf6!! This game is well above my level of understanding! Gonna have to let the engine have a deek at this. Caruana must have seen 15 moves ahead!? The mind boggles, and the irony because this is a very Nakamura style game. Brilliant. |
|
| Jan-18-17 | | YouRang: <izimbra: <<Eyal>: I let my own Stockfish look at the position - it suggests 23.Rd3 instead of c4 and at a depth of 30+ actually starts showing a significant advantage for White. This rook move has all kinds of ideas - Ra3 to attack a6, doubling on the d-file, preventing castling (23...0-0? 24.Rg3+ Kh8 25.Rhg1), and the threat of Rc3 followed by Bb6 or Ba7 (for example, after the very natural 23...Rg8?, 24.Rc3 is winning). Black's best defensive plan is apparently to play Rb5 and give up the exchange on d5. If Black doesn't fall for any specific tactics, I suppose a winning idea in the long run would be to attack the weak pawn on a6 and advance on the Q-side.> 23.Rd3, a logical move, does look stronger for White, but I still see a game that's solidly in the draw range, lacking a way to force a black loss.> I thought I would take a crack at settling whether <21.Nf5!> was winning by following the best moves calculated deeply with a strong engine.

Looks like we're heading toward a white win. |
|
| Jan-19-17 | | Eyal: <YouRang> As mentioned in my last post here (quoting the correspondence player who analyzed this line in his blog months before it was played by Caruana), the more direct <23.c4> - aiming for the c5 break and also stopping the defensive resource Rb5 - should be winning as well, only after 23...Be7 White should continue 24.Kb1! rather than Kc2, which was originally mentioned by <izimbra> here (apparently that's what the engine shows at first). |
|
| Jan-19-17 | | Xeroxx: Carry-You-Ana. |
|
| Jan-19-17 | | YouRang: <Eyal> Yes, sorry I overlooked that in your earlier post, but as predicted, the computer was very slow to find <24.Kb1!>. Once it sees it, then 23.c4 becomes its new favorite move. It's always fun to find positions that baffle the computers. It feels like a win for humanity. :-) |
|
| Jan-19-17 | | YouRang: FWIW, now that my computer has been "trained" to see the strength of answering <21.Nf5 Bxf5 22.Bxf5 Rb8> with 23.c4! Be7 24.Kb1!, it now sees three potential winning moves when I backtrack to move 23:

+0.00 23.Rh2 Rb5 24.Rh3 Rxd5 25.Rxd5 0-0 26.Rg3+ While 23.Rd3 was the move the engine first learned to like, it has now dropped to third place. It looks like the immediate 23.Kb1! is quite strong. Admittedly, I would be at a loss to explain why... In any case, it looks like 21.Nd5! was a deep winning shot by Caruana, even had Nakamura played it better. |

 | | Alex Schindler: Can someone explain why 25 h5 instead of going ahead with Be3? Haven't analyzed with computer, but I'm having trouble seeing what it addresses. Nor do I see the point of black's response qg5+, simply inviting the bishop where it wants to go and threatening nothing in particular (that I can see) given the threat of a rook on the G file. Not that I see a whole lot of options for black, but what was that supposed to accomplish? 29 b5 is also mysterious to me. Is that just to block the a4-e8 diagonal for the eventually unpinned black queen? |
|
| Mar-14-17 | | 7he5haman: <Alex Schindler> if 25.Be3 then maybe(?) 25...Rfd8 is good, which can't be played after 25.h5 because of 26.Bh4. 25...Qg5+ may have been a reaction to the threat of 26.Bh4. Honestly I don't see how Black can stop the dual threats of 26.Be3 and 26.Bh4. It's hard to suggest a better move without a computer / better chess brain! |

Rh6+ 1-0.Commentators are calling Caruana, Nakamura and So the Big Three of American chess, after leading the US to Olympiad Gold in 2016, with talk of a C-N-S triangle similar to the K-A-K triangle of Kasparov, Anand and Kramnik from 15 years ago. This sharp Sicilian Najdorf line has already shown up in this year's Top Ten A Giri vs M Vachier-Lagrave, 2016 which went 15 ... Rg8 16. Rdg1 d5 and Black won with a brutal attack. Car-Nak scored well by trading the Queen for two pieces which is always pleasing, yet it also demonstrates the crucial distinction between active and passive pieces; like so many White victories, Black's forces are mostly bystanders while the King gets hammered. Fritz the anti-human cyborg was generous with "?" as always, while frugal with "!" here, but remember these tactical slugfests will have lots of computer improvements that are not at all so easy to find over the board. Lots of great posts in this thread, but don't miss the 34. Bc5+!! suggestion pointed out by <mistreaver> on Page 2. |

| Sep-07-17 | | Monocle: Games like this make me wonder why the tradition of brilliancy prizes has more or less died out. Did Gazza's outburst at Linares 2003 kill them off, or were brilliancy prizes on the wane even before then? And would we get more exciting chess if significant brilliancy prizes were awarded at more events? |

| | ChessHigherCat: Caruana seems so brilliant in this game that he seems to be off in his own world at a completely unattainable level, which raises the question: Does he play less brilliantly now, or is it just impossible to shine against Carlsen? Even great tacticians like MVL and Mamedyarov seem to play relatively boring games against Carlsen. |
