London Classic: Nakamura misses win against Carlsen

by Alex Yermolinsky
12/9/2017 – What a fun round it was. Round six may not have had many wins, but it was not short of excitement. The big game was between Hikaru Nakamura and Magnus Carlsen, with the American completely winning all the way until move 59 when he missed his chance. Aronian continues to play with no inhibitions, though drew against So, while Nepomniachtchi beat Adams. Report and analysis by GM Alex Yermolinsky. | Photo: Lennart Ootes

Chess Endgames 14 - The golden guidelines of endgame play Chess Endgames 14 - The golden guidelines of endgame play

Rules of thumb are the key to everything when you are having to set the correct course in a complex endgame. In this final DVD of his series on the endgame, our endgame specialist introduces you to the most important of these rules of thumb.


Round six

The leader, Fabiano Caruana, had Black against Vachier-Lagrave, and surprised his opponent with the Petroff. The game followed an old trail from Svidler-Ivanchuk, Morelia/Linares 2007. I wonder if Maxime was aware of that. If he was, it's OK. Maxime certainly has tried his hardest in 2017, and he has reason to be disappointed with missing the Candidates. Time to finish this tournament with a solid 50% result, cash in the $50,000 2nd place Grand Chess Tour prize, and go home to rest and recharge the batteries.

Anand-Karjakin had a promising start with a sharp English, but Vishy saw something unpleasant in the lines following Sergey's novelty on move 12, and decided to wrap up the game with repetition.

The former world champion also had some interesting comments on the recent AlphaZero news:

"Oviously this four hour thing is not too relevant — though it's a nice punchline — but it's obviously very powerful hardware, so it's equal to my laptop sitting for a couple of decades. I think the more relevant thing is that it figured everything out from scratch and that is scary and promising if you look at it...I would like to think that it should be a little bit harder. It feels annoying that you can work things out with just the rules of chess that quickly."

The other three games went full tilt, and offered a lot of enjoyment to the spectators.

Wesley So must have prepared for this line of the Ruy Lopez, as Aronian plays it all the time. What Wesley didn't count on was Levon's extremely aggressive response. Levon is playing like he's having a a good time in London, which bodes well for his chances at the big show in Berlin in the spring.

Nepo finally lit the scoreboard with the game nobody expected him to win. Maybe that's the ticket to successful play in elite tournaments: sit tight and wait for your chance. Ian is learning this the hard way, as his stints in top tournaments are coming to an end for now. One has to be rated way higher than 2750 to get invitations to premier events. At 27 years of age, Nepo still has time for another rating push.

Mickey Adams is an old warrior, who simply never quits. Last year at the London Classic he was able to draw all of his games. Not this time though, but there are still three rounds left, and I root for Mickey to win!

Chess Endgames 8 - Practical Rook Endgames

Rook endings are amongst the most frequently encountered endgames there are. And it is precisely the area in which the effort put into training is particularly quickly repaid in the form of half and full points, because the knowledge of even a few rules of thumb and methods makes life a great deal easier and provides a guiding light even in complex positions. The second DVD in Karsten Müller’s series on the endgame was concerned with theoretical rook endings and was structured according to the distribution of material, but this DVD focuses on the themes which are to be found in rook endings.

Karsten Müller also wants to help you with the training of your intuition. After all, the real art of the royal game can best be seen in the recognition of exceptions to the rules.

Happy 30th Birthday to Hikaru Nakamura! What would be a better way to celebrate than a win over the World Champion, Hikaru's old nemesis, Magnus Carlsen. It almost happened.

A fascinating battle it was from the opening to the middlegame, and I wish I had the time to analyze this game in depth. The parameters of this report only allow me to focus on the final stage.

Chess Endgames 9 - Rook and Minor Piece

Endings with rook and minor piece against rook and minor piece occur very frequently, even more often than rook endings. But there is not much literature on them. This endgame DVD fills this gap. The four different material constellations rook and knight vs rook and knight, rooks and opposite coloured bishops and same coloured bishops and rook and bishop vs rook and knight are dealt with. In view of the different material constellations Karsten Mueller explains many guidelines like e.g. "With knights even a small initiative weighs heavily".
Video running time: 7 hrs. 38 min.


Here were the World Champion's thoughts after the game. He is clearly suffering from a cold here in chilly London.

We can see now that Magnus Carlsen dodged a major bullet today. While it might inspire him to try his hardest in the remaining rounds, one has to wonder why Carlsen cannot translate his dominating performances in rapid and blitz events into similar results in classical chess.

Hikaru's enterprising play in London hasn't been rewarded with wins yet. Yes, chess can be very cruel at times.

Naka misses an easy win.
2800 players aren't what they used to be. Inflation much?
scoobeedo scoobeedo 12/10/2017 03:47

You know a thing or two about rook endgames.

Are you sure that this is enough knowledge?

Or should you better try improve to knowing three or four things about rook endgames?

Hehe ...

btw, dont twist my comments, i said i love yasser. i put him at the top of other top players past or present who can break down and explain the game of chess to woodpushers like us. i said the commentary team including yasser lean to heavily on the computer, which is what any amateur can do at home.

welcome to the world of trolls yermo, keep up the good work. i enjoyed your analysis, its a thankless job in the computer age. and boxikg, im czechpirc on lichess, you can put your money where your mouth is and challenge me to a game anytime

The mainline given in Nakamura-Carlsen with 44.Ke3 is a draw after 48.Rxc3 according to the 7-piece Lomonosov tables. I think 55.Ra5+ leads to a win, but it is also still tricky if Black retreats the King instead of 55...Kd4. It may turn out that White has done the whole maneuver with 51.Nd4 merely to win a tempo...
AlexYermo AlexYermo 12/9/2017 04:24
@hammerchewer Did I say Black was winning in Hansen-Leko? I only stated that White had to defend it, and Black eventually won. I mentioned that line as White's defensive option, along with the game continuation, and some other suggestions. Of course, it is a draw most everywhere, but the defender's task is not as simple as it may look to a casual observer.
I had the same e and f vs g-pawns ending against Duong, Canadian Open 2007, and also managed to win after my opponent made a mistake after over 100 moves of play. You can look it up in databases.
Trust me, I know a thing or two about rook endgames. The defender will get tired if he keeps on giving ground and changing his defensive stance, even though it's objectively still a draw.
As for your suggestion of "checking tablebases before commenting", I don't think this was the response I was looking for after pouring over that endgame for a few hours last night.

@boxikg, yet even experienced GMs may fail to evaluate such endgames correctly, even after post mortem analysis: for example, GM Yermolinsky is wrong when claiming Adams lost after 70.Rh4, since according the tablebases the decisive mistake actually occurs on 71.Rb4?, whereas 71.Rc4 is meant to be one of many drawing moves, but please do not ask to a human player why on earth a move which puts the white rook as far as possible along the "wide side" should be bad! 12/9/2017 01:18
@czechpirc76 Who are you to insult anyone? Yasser without engine help does not know if position is won or not and you know? He was great player and later great chess teacher and who are you?

In Adams v Nepo', Yermolinsky's line at move 50 should have led to a draw. In Hansen v Leko, which he cites, White defended perfectly for several more moves from his diagram position until 95 Ke2?? whereas the fairly obvious 95 Rb2, preserves the draw. Evidently tiredness and the clock lead to mistakes in practice, but Yermo's comment was misleading. Please check tablebases before commenting on simplified endings where the correct result can be checked.

so simple right? turn off the engine and it isnt. these guys are human as well and the trolls with the beast running in the backround need a reality check. i love yasser but the commentary team constantly using the engines ruins the element of analysis that can help even masters improve and understand the game better. i call a ban on commentary teams using a computer, its boring/lazy and just gives more fuel for the mindless trolls like boxikg

engine's eval is irrelevant in human chess. those commentators see the engine's lines all the time. they are helpless without it. naka has had a good score against carlsen recently. he simply made a mistake. it happens. 12/9/2017 09:21
I could not believe my eyes yesterday. Nakamura obviously has some mental issues playing Carlsen, with plenty of time on the clock he let win slip. Here on chessbase at one point (54. Nd3) engine evaluation soared to staggering +128 in white favor but still Nakamura managed to blow it somehow. Carlsen was completely busted and it was a matter of technique every super GM has to finish him off. Plan of playing Ra2 and attacking c3 pawn both with rook and knight was obvious and not so incredibly hard to see for someone who belonged to 2800+ club not so long ago and with almost a half an hour on the clock. Even Yasser and other commentators on c24 were stunned since they very well knew position was dead lost for Norwegian. Hikaru gave him new blood and he now could potentially fight even for top spots with two white pieces in remaining three rounds and almost surely win overall Grand Chess Tour. To recap MC is still probably the best player around but he has not won super GM event for more than 1.5 years (Isle was not round-robin event with many big guns he played against), was very modest in WC title match in last November and in World Cup this year, here he blew it in games vs Fabi and So, had very lucky escape yesterday ... Very unconvincing to say at least, very vulnerable. Others simply can not take advantage of that - it is up to them to beat him when he is playing badly, he will not resign without fight that is for sure.
