|Apr-06-14|| ||morfishine: <DcGentle> At the very least, if Carlsen offers a Caro-Kann, Anand should play the advance variation, at once! :)|
|Apr-06-14|| ||DcGentle: <morfishine>: Obviously the push of the a-pawn in the advance variation is still not very much known on GM level, apparently. I could tell you a reason or two for this. For example there was no publication of The World vs Akobian, 2012 in any renowned magazine, although it was deserved. But even this point was mooted, so no one needs to wonder.|
|Apr-06-14|| ||morfishine: <DcGentle> You mean the e-pawn, right? |
1.e4 c6 2.d4 d5 <3.e5>
|Apr-06-14|| ||DcGentle: <morfishine>:
In this line, the start of the game went like this
<1. e4 c6 2. d4 d5 3. e5 Bf5 4. Nf3 e6 5. Be2 Nd7 6. O-O Bg6 7. a4 Ne7 8. a5 Nf5 9. c3>
and the a-pawn is pushed twice: <7. a4> and
<8. a5>. The fact that Black did not prevent White's 8th move was considered an inaccuracy, but there is analysis that also blocking this pawn is already too late.
And of course <9. c3> was leading to the closed game which gave White so much advantage later on. In my view this move refutes Black's <6... Bg6> maneuver, and I haven't seen any game that featured the same opening line since we played it. Most GMs play <Nc3> and don't push the a-pawn at all, which of course is not as strong as White played here.
Position after <9. c3>:

Black to move has already lost, according to game analysis available.
Of course one can even argue that Black should be losing earlier, but more analysis is required, although I have done a lot already. At least it's doubtful that Black can ever get a good game with this variation, if White doesn't blunder.
|Apr-06-14|| ||cro777: Human minds still critical to chess evaluation.
"Much had been made of Viswanathan Anandís and Magnus Carlsenís team of seconds. Over the years, the technology that players use and how they use it have become just as important as members of their backroom team...An idea was sprouting in the mind of chess players around the world: if a computer could play the game better than humans, then surely they would make a better second than a human!"
GM Susan Polgar thinks that the computer cannot replace humans in a playerís backroom team:
"The role of seconds is equally important. Different software give different evaluations. Therefore, you need competent seconds who are able to <properly translate the evaluation and make the correct judgement>."
The role of Nakamura's second Kris Littlejohn, who is not even an International Master, is also very interesting:
"Kris has built a computer for Nakamura, a Nehalem i920 3.2 GHz processor-based tower with 6 GB of RAM. Once he knows which players Hikaru will be going up against, he analyses the openings commonly used by Hikaruís opponents. He uses branching to predict possible moves that a given opponent could play."
|Apr-06-14|| ||DcGentle: <cro777>: Interesting. But more is needed than just an interpretation of an eval, in my opinion. For sure this is helpful, but as we know, that's not the end of it. Carlsen will play moves not being predicted by any current software, and not even a supercomputer might help in these cases, because even the fastest box can only produce the results any software will allow them to produce.|
We live in interesting times, anyways.
Engines have become strong and have to be called assistants to be taken seriously. But they are not perfect yet.
|Apr-06-14|| ||cro777: <DcGentle> As far as Carlsen is concerned it would be interesting to use the Play Magnus app to try to predict his moves. But you may start working on a program, similar to Kris' one, for our next GM challenge. The other grandmasters are more predictable.|
|Apr-06-14|| ||DcGentle: <cro777>: Whether my engine is ready to go in a few months, I dunno yet. It's a complicated endeavor. You see, I am employing a new method not having been tried before in chess. Currently I have problems to get the knowledge into the the algorithm, especially positional knowledge, which is not easy to describe in the first place.|
Fundamentally this method will open up totally new possibilities, for example the program could search for Zugzwang situations or even a fortress or blockade to avoid or to build, respectively.
But the devil is in the details.
|Apr-06-14|| ||DcGentle: There is life on my forum, if someone is interested.|
|Apr-06-14|| ||cro777: <DcGentle: I am employing a new method not having been tried before in chess.>|
This is a very interesting and long range project (a new paradigm). But a predictive model like the one that Kris had built for Nakamura should not be a difficult task for you.
|Apr-06-14|| ||DcGentle: <cro777>: Well, <lambda> has created a script that acts like an interface to steer an engine in order to explore several possible lines like a human analyst would do. Of course a human, who knows a lot about chess, would avoid some lines that the <lambda> script must travel along, because it lacks experience.|
I could program something like this as well, but I wanted a new kind of engine, which additionally might not necessarily need the fastest processor on the market to work well.
Current methods must wade through millions of positions because they have no clue where to search. And still they can miss some decisive positional features of variants available. There is a better way, I hope.
|Apr-08-14|| ||DcGentle: Today I was shocked. <chrisowen> answered to <Sally Simpson> on plain English! : Tarrasch vs Kolb, 1894|
|Apr-09-14|| ||morfishine: <DcGentle> Yes, from time to time, <CO> will post in plain English. Not often, but occasionally. <CO> is a very strong player|
|Apr-09-14|| ||cro777: Today, at the Women's FIDE Grand Prix, five games out of six ended in white victories. The only game that was not won by the white pieces, but it certainly could have, was Stefanova vs Kosteniuk.|
Position after 57...Ke4

In the diagram position Stefanova played 58.f8=Q? and the game ended in a draw.
She could have won, for instance, by playing 58.g6
58. g6 Nxg6 59. Kxg6 Kd3 60. Nb7 Be7 61. Na5 Bb4 62. Be5 Kc2 63. Nc4 Bc5 64. Bd6 Bxd6 65. Nxd6 b2 66. Nc4 b1=N 67. f8=Q
|Apr-10-14|| ||morfishine: <cro777> A pity; 58.f8=Q has to be called a slip, maybe due to length of the game, who knows|
|Apr-11-14|| ||cro777: Chess is sometimes a game of work!
In the crucial game for the 1st place in the 2014 Polish Championship: <Duda, Jan-Krzysztof (2563) - Wojtaszek, Radoslaw (2713)>, after
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 h6 8. Bh4 Qb6 9. Qd2 Qxb2 10. Rb1 Qa3 11. e5 dxe5 12. fxe5 g5 13. exf6 gxh4 14. Be2 Qa5 15. O-O Nd7 16. Kh1 Qg5 17. Rf4 e5 18. Nd5 exd4 19. Qxd4 Kd8 20. Bg4 Bc5 21. Qd2

Wojtaszek played 21...Bd6!
"Such a move is just impossible to find over the board. It is clear that Wojtaszek knew it and yes, chess is sometimes a game of work!" (GM Arkadij Naiditsch)
The game continued:
22. Qa5+ b6 23. Rxb6 Bc7 24. Bxd7 Qe5 25. Kg1 Rb8 26. Qb4 Bxb6+ 27. Nxb6 Qe3+ 0-1
Duda is just 16 years old. It seems he fell into some nasty home preparation. (Wojtaszek is known as a "theoretical beast", especially in his main repertoire).
"We can see one more time how much chess has changed. On the top level, analyses are deep and players have to remember a lot not to get in deep trouble in the early stages of the game." (Naiditsch)
|Apr-12-14|| ||morfishine: <cro777> Now thats a sharp, exciting game! |
Speaking of preparation (or work), do you think Anand's legendary preparation acumen will be enough for him to have a reasonable chance of victory vs Carlsen? I think Anand needs to prepare comprehensively, that is tournament-wise and match-wise, to maintain the balance [ie: not lose control of the match]. Also, Anand could benefit from a basic overhaul in his approach to match-play in general. I think it would be wise for Anand to thoroughly prepare one or two lines (besides 1.e4) in an attempt to keep Carlsen somewhat off-balance. The main point here would be to strive for super-solid positions that have zero-chance of losing
With that said, I think Anand should "go for the throat" early, so to speak, and try to net a victory, ideally within the first 2-games. The view here (in such a short match) is to get the lead early, stay unbeaten through the middle stages, then save his remaining preparation for the last 3 games or so. Sort of like what Kramnik did in last year's Candidates, maintaining his position, and going all out in the later stages. The difference here is Anand would try to gain a win early, first.
|Apr-12-14|| ||cro777: <morfishine> Anand is changing his style of play. Could he play against Carlsen like he had played at the Candidates tournament (where he played dynamic chess and a good endgame).|
Anand also promissed to change his team of seconds. In Chennai, the most creative of his seconds was Sandipan Chanda. Sandipan was also his second at the Candidates tournament. The other core members of his team were Sasikiran, Leko and Radoslaw Wojtaszek.
Anand said: "I am planning to re-jig my core team and there would be a couple of surprises. Ideas are being thought about." As GM Harikrishna pointed out:
Anand needs, in his core team, a player(s) who can think like Carlsen!
|Apr-13-14|| ||morfishine: <cro777> An interesting coincidence: After the Candidates I was musing to myself: "What Anand needs is Kramnik as his second!". At almost the exact same time <DcGentle> mentioned to me that Kramnik was good friends with Anand and would make a great second. I had no idea they were such good friends and my wondering was purely in jest. Perhaps it will come to be. Somebody like a Kramnik would be beneficial from a positional perspective while also enhancing Anand's general match preparation, IMHO. |
|Apr-13-14|| ||Patriot: Hi <morf>! Here is Dan's response to the "theory" I had:|
"Playing potential increases with knowledge." - I don't believe this; I think abilities are more important and your potential abilities limit your playing potential, as you develop those abilities and pick up knowledge.
But yes, you get diminishing returns on areas where you are already good. Your "chain" is only as strong as your weakest link, often.
And yes, doing things way above your level also often gets diminishing returns.
Hopefully you can balance your play and theory! :)
The triangle: Study - Play - Get Feedback as in the NN "The Improvement Feedback Loop"
<<When you look at it from this angle, it's easy for me to see that many Saturday and Sunday problems are ridiculously too advanced for me at my stage of improvement. Sure, I may figure them out if given enough time but I think there is very little to be gained from this (for my level). It's like a 6th grader trying to work out a college level math problem, and even if they accomplish this with much effort it is misleading to believe they are just as good as a college level student.> I have mixed feelings about this comment. Don't sell yourself short. If you can work through a problem (even though it may take a lot of time) its not an issue of knowledge, but an issue of calculating speed or pattern recognition or both. After all, one has arrived at the correct solution, so that has to be a plus. I would think a 6th grader would be thrilled to find the correct answer and could care less about how much time it took.> I had some mixed feelings about my own comment as well but decided to throw it out there and see what your opinion is. It may be a better analogy if I said it wouldn't be very useful for a 6th grader to attempt college level algebra, before they learn the basics leading up to it. It's sort of like playing someone 500 rating points higher. It may turn out to be dehumanizing if done too often. Dan suggests 150-200 rating points higher at the most so that you are punished for bad moves, but they are not so high that they don't make some mistakes that give you a fighting chance.
|Apr-13-14|| ||cro777: Good news for endgame lovers: the re-introduction of adjournments.|
The second edition of the ACP Golden Classic will be held from July 12-20 in Bergamo, Italy.
The interesting part of this "unusual" tournament is that the players will be competing under the same time control as was used in the World Championship matches in the Golden Era of chess: 2,5 hours/40 moves + adjournment.
According to organizers, the re-introduction of adjournments should "provide an occasion for producing highly spectacular and imaginative chess, by giving the seven gladiators the most important ingredient needed for exploiting their skills and fantasy: time to think...
Hopefully the formula of the event should finally present chess lovers worldwide with a selection of high-level endgames".
|Apr-14-14|| ||cro777: Asked if he would consider working as a second for Anand, Kramnik said: "To be honest, I donít know. I havenít thought about that at all...If Vishy makes an offer I can think about it."|
|Apr-16-14|| ||cro777: The lost art of common (positional) sense in chess.
GM Lars Bo Hansen: " I am staunch advocate of the value of logical thinking and common sense in chess. Even in this time and day where analysis engines point out one exception to the old dogmas in chess after the other and where concrete variations seem to be the norm, I believe thinking logically and applying common sense can take you a long way in chess.
In round 3 of the Danish Championship, logic and common sense helped three Grandmasters win instructive games that are worth studying. In all of these games, logical thinking and common (positional) sense were more game-deciding factors than sharp calculations or intriguing combinations.
|Apr-16-14|| ||cro777: "Over the past two decades, the influence of powerful chess programs has profoundly changed the game of chess. Chess has become a much more concrete game with precise calculations. The narrow specific approach to each position has virtually replaced the more intuitive and general approach developed by the old masters.
For young aspiring chess players, this computer development comes with many pitfalls. To be successful in chess, building understanding and logical thinking must precede the use of computer-assisted analysis." (Lars Bo Hansen: "The Lost Art of Common Sense in Chess (What Would A GM Do?)")|
|Apr-17-14|| ||sevenseaman: Hi <morfishine>, how do you do? I am here in the US, (SanJose, ca) since April 15th and shall stay for some time.|
