Sep-09-17  Toribio3: I think GM Carlsen underestimated the humble Chinese GM. Xiangzhi has the skills to beat the reigning World Champion because of a mindset that the courageous Chinese GM is of low caliber quality. From now on, Carlsen must prepare on a good and solid opening even against the lowly grandmaster from anywhere on Earth!

  visayanbraindoctor: <Jonathan Sarfati: Score one against what Visayanbraindoctor calls "Narcissistic Generation Syndrome"? Capablanca vs Marshall, 1918>

Definitely. There were masters in the past that I believe were better defenders than Carlsen (such as Lasker, Capablanca, and Petrosian). (Having said that, I believe that Carlsen IS the best defender in the world, currently, together with Karjakin.) <21. Re2, as <SirRuthless> suggests, appears to be an idea that the human mind, and especially a Super GMs mind, can easily understand.> Capablanca probably would have moved 21. Re2 in a jiffy. It looks like a perfectly logical move to mobilize the rook. From 1909 to 1924 Capa made something like less than a single definitively losing error per year, and in several cases defended more difficult positions than this, including the game above where Marshall introduced his brilliant idea for the first time. I believe it was his ability to see and avoid tactical errors better than anyone in chess history which made him nearly invincible. (You have to make a losing error in order to lose, and the young Capablanca did not make many of those.)

Going back to Bu's dauntlessly courageous strategy for this game, I believe this again is another proof that it's the only way to play against Carlsen and still hope to win. Bu offers a gambit pawn, Carlsen as usual grabs it (he always does). Bu sacs a Bishop. Carlsen tries to retain the piece with 17. Nf1 when he could have immediately bailed out into a draw with with 17. Qf3 Bh2+ 18. Kh1 Bg3+ and perpetual. Carlsen rises up to the challenge of the gambits (which I like about him), but fails to survive the tactics (this time).

On the other hand, Carlsen is quite unbeatable in positional play. No one has positionally outplayed him for the longest time. As I've posted before <He builds up minute advantages like a juggernaut and grabs on small mistakes like a crocodile, irresistibly dragging his opponents into the swamp.> He has this 'swampy' style of play that sucks in even the strongest of today's GMs into the cloying mud. Had this game gone along quieter positional lines (say Bu did not essay the gambit, or if Carlsen had declined it), I would give Carlsen a 60% chance of winning sometime in the endgame. These positionally maneuvering Ruy and Italian positions seem to particularly suit his style.

Note that ALL the (five classical) games which Carlsen has lost this year were lost due to tactical mistakes or misjudgements in sharp positions. The same pattern mostly applies in the past decade. After having said that, one must note that Carlsen is one of the best tacticians in the world too. It's just that this is the only field where he can be predictably beaten.

The suggests something important for his would-be Challenger. Deploy the sharpest, but still sound openings, against the World Champion. Try to keep the middlegame double edged if such an option is possible. Try to decided matters before you reach the endgame. (This strategy actually worked for Kasparov against Karpov in their second match, so it's not without precedence.)

And if there are other options, do not play passively like this Carlsen vs Karjakin, 2017

Food for thought for the next World Championship match.

Sep-09-17  The Kings Domain: Nice win by Xiangzhi, he could score the biggest upset of the tournament. It's games like this that nearly make up for the Demchenko and Kovalyov fiascos.
Sep-09-17  1971: That's an amazing post, VBD. Thanks for sharing. I read it like 10 times.

  Honza Cervenka: <SirRuthless: 30. Rd1 is not a human move with 7s on the clock. It locks the K in with no cracks to escape to the Q side after 30...Bg3+ and 31.Kf1 is forced. That looks insane to the eye. Impossible to play that in a real game;that's the definition of an engine move.>

I don't think so. In fact, 30.Rd1 is quite logical move, as in some variations the Rook on a1 is simply hanging (let's say after any "pass" move like 30.a3 black can unpin the Rook on g6 by 30...Kh6 and now Rg1+ or Qxb2 look like a serious problem for white with unprotected Rook on a1). 30.Rd1 also brings the Rook into the game. Of course, at first glance the position after 30...Bg3+ 31.Kf1 looks dangerous for white but if you look at it for a while, you can see that white is ok here. White Queen protects f2, and black with uncovered King and still pinned Rook has no way to strenghten his pressure facing quite a lot of Queen checks with perpetual in many lines. It was not impossible to figure that out over the board, of course with more than just a few seconds left on the clock. On the other hand, it was quite apparent that white's attempt to flee with King to the Queenside turns passed h-Pawn into decisive factor in the position. Magnus simply made a bad decision in critical situation, and it decided the outcome of the game. After all, he is a human and humans may err.

  MissScarlett: <30.Rd1 is quite logical move>

Yes, with the understanding that human logic and silicon logic are somewhat different. Rd1 not only brings rook into the game, as you say, but gives the King a potential escape route via d2-c1.

If Magnus chooses to style himself after <Joe90> he must expect to be held to a very high standard.

  ahmadov: I should admit I like to see the World Champion losing a game, losing with a style at that.
Sep-10-17  kinggeorgia: Its a draw,if only Carlsen move Qf3 on the 17th, and Bu would settle for a perpetual check and a draw since he was a piece down.
Sep-10-17  Clement Fraud: BRAVO!! I like the way Bu Xiangzhi plays. White loses out in this opening when he plays d2-d3 so early, as this allows black to equalize with his Bishop placed on e7.

To refute the Hungarian Defense, white needs to keep open the option of playing d2-d4 (1.e4 e5 2.Nf3 Nc6 3.Bc4 Be7? 4.d4!).

  Jonathan Sarfati: <visayanbraindoctor: Capablanca probably would have moved 21. Re2 in a jiffy.>

Compare 16. Re2 in Capablanca vs Marshall, 1918 Capa had a good feel for the defensive power of major pieces. In My Chess Career, he emphasised the defensive power of his Q on f3 while it kept pressure on f7.

  visayanbraindoctor: <Jonathan Sarfati: <visayanbraindoctor: Capablanca probably would have moved 21. Re2 in a jiffy.>

Compare 16. Re2 in Capablanca vs Marshall, 1918>

I should have said <almost certainly> instead of <probably>. After all Capablanca, in a similar situation, did move Re2 in order to mobilize his rook.

More mind-boggling is this post from the Capablanca vs Marshall, 1918 page.

<Shajmaty: In 23 moves (between 14. ♕f3 and 36. ♗xf7+), Capablanca plays the best move (i.a.w. Stockfish) 21 times!>

Why?

1. That game is one of the most complicated double-edged and tactical games in chess literature. Virtually replicating the best computer lines move after move for two dozen moves in real time in such a game is almost inhuman. I doubt if any living master nowadays could do such a thing. We would be seeing lots of red moves live in the internet.

2. When the thematic Marshall-type position first arose in that game, no one much knew anything about it (except Marshall who prepared it). There was no precedent available to Capablanca. Yet he played it almost perfectly. Capablanca was a freak of a chess player.

Sep-11-17  Ulhumbrus: Instead of 19 Bb3, 19 Bd2 connects the rooks.

20 f4 disturbs the king side pawns. Instead of this 20 Bd2 connects the rooks.

22 Rxe3 helps to develop Black's rook. Instead of this 22 Bd2 connects the rooks.

After 23...g5 Black threatens 24...Rg8 followed by 25...gxf4+. Instead of 24 Kf2, 24 Rc1 prepares to develop the piece placed worst, the queen's rook. On 24...Rg8 25 fxg5 avoids opening the g file for Black's rook. However Black can avoid this by playing 24...gxf4 first. This suggests 24 fxg5 avoiding opening the g file and on 24...hxg5 25 Rc1 gets ready for 26 Rc2 but 25...f4 refuses to wait for Rc2. This suggests 24 fxg5 hxg5 25 Qc2 pinning the f5 pawn and getting ready for Qg2 and Qh2

Sep-12-17  Clement Fraud: <Ulhumbrus> <20 f4 disturbs the king side pawns. Instead of this 20 Bd2 connects the rooks.>

As I see it, black was threatening to advance his KB Pawn to f4 & f3 (creating an unavoidable mate with his Queen on g2).

Sep-12-17  blackdranzer: Ulhumbrus ..I don't mean to offend but some of your analysis is wrong . Not just this post but as I have observed. Sometimes the suggested moves ( which you suggest ) are worse although it might have some logic behind, like Bd2 connecting the rooms and so on.

Sep-13-17  beatgiant: Chess teaches us the importance of understanding how to balance the general and the specific.
Sep-13-17  Arconax: That is true. The Classical School taught us about the general aspects, while the Soviet School focused on the specifics of the position.

It is finding the right balance that is the key to true chess mastery.

You don't analyze, Ulhumbrus. You just select from your small stock of <My First Book of Chess Strategy> chesshomeric epithets:

"disturbs the kingside pawns without necessity"

"moves an already developed piece"

"connects the rooks"

etc.

As in an epic poem, whether the chosen epithet relates to what is actually occurring at a given moment is matter of chance.
