|May-18-17|| ||chessgames.com: <WannaBe> Fair question, but a little tricky to answer. Let me put it this way.|
The algorithm for receiving a new PGN game: it looks at the event name and the year. Suppose it says
[Event "Chessgames Open"]
The software will then look to see if the tournament name already has an entry with name="Chessgames Open" and year=2017.<*> If it already exists, then the game will be assigned to that tournament. If it doesn't a new record will be created and a new tournament ID is born and this game will be the first to be assigned to that.
Everything you noticed about tournaments are a consequence of that method, combined with the fact that admins can modify this data later.
For example: <some tournament have names but no games> — they used to have games but either an admin moved those games into a different tournament, or the editors as a whole put it in the Tournament Index for simply a better description of the event.
<tournament have games, but can't post any kibitz> — by default, you can't post to a tournament. It requires it to have homepage status and/or Tournament Index inclusion. As new games come into the database all the time this is their default status.
<were these tid pre-assigned, and just waiting for games to be filled in?> Not per se; when we first got a tournament for some event we make the record.
<*> = <note, the algorithm for detecting tournaments by matching names and years is somewhat sensitive to the possibility of events around Christmas time that span the end of one year and the start of the next. the exact logic is a combination of hacking, heuristics, and elf magic.>
|May-18-17|| ||WannaBe: <CG.com> Thank you for the response! =)|
|May-22-17|| ||chessgames.com: We're ready to beta-test our new Stockfish® server. I'm looking for a few volunteers to play around with it.|
You can also ready see the benefits of the engine on the Opening Explorer and Similar Games, but the real fun will be when you get to suggest moves to games and get evaluations back. It also has a nice feature where it can analyze the end of the game to answer that perennial question, "What's the finish?"
We've already hobbled together a help section on the feature here: Premium Membership Help Page.
So if you have interest in helping us debug this system, please let me know. We're just looking for a few good men (or ladies).
|May-22-17|| ||WinKing: You might want to change <Positive numbers mean that White is winning;>.
I think you mean 'White is better'.
<2. Opening Explorer - For most pages on the Opening Explorer you will see a small icon reading "Engine" with an evaluation next to it. For example, if it says 5.dxc5 +0.41 (30 ply) that means that Stockfish regards 5.dxc5 as the best move, and the evaluation (in pawns) is +0.41, and it probed 30 ply (15 moves) deep in all variations. <Positive numbers mean that White is winning;> negative evaluations mean that Black is better. You can click on the "Engine" button to see a more thorough evaluation of the position.>

The third game in the list says it has 3 moves. In reality it has 26.|
|May-23-17|| ||chessgames.com: <Offramp> How odd; must have been due to the invalid PGN at the very end.|
<WinKing> Yes the documentation needs a lot of work, and we've yet to make advertising materials. Right now we're just focused on making it work well. If you (or anybody) would like to play around with it for real, just give the word and I'll put you on the beta-tester list.
|May-23-17|| ||offramp: I'm not a big fan of the Stockfish evaluations for openings. If you have an opening like the Fried Liver, Stockfish (this sound so like one of my recipes) will probably give an evaluation of minus 5 after move 6. Many people will throw the whole line into a dustbin without considering the line's practical chances, beauty, history and humour.|
|May-23-17|| ||chessgames.com: I know exactly what you mean, but that's more of a problem of the way people interpret the evaluations than the evaluations themselves. There are some very useful applications, for example discovering tactical refutations or the proper way to defend a difficult position.|
|May-23-17|| ||WannaBe: "Look at every move, especially impossible one".|
That's why I am always afraid when my opponent opens with 1. Ke4
|May-24-17|| ||OhioChessFan: Not a big deal, but if there's a simple fix for what I'm about to suggest, it would be nice for reviewing tournaments. As an example, per:|
Is there an easy way to show the round number of each 0-1 result?
|May-24-17|| ||chessgames.com: <Is there an easy way to show the round number> Not yet but it's coming for sure. |
Like many facets of CG, in the early days the data was so horrible that to display it would be a farce. But things have improved since 2002: now all of the new tournaments have reliable round numbers and the tireless volunteers have really helped the old PGN, so including round data is finally viable.
|May-24-17|| ||WannaBe: <chessgames.com> Got a funny request, and wonder how easy it is to implement...|
Can you put in a 'feature' that will ignore a whole forum/page.
Say another big flame war broke out, and I'll just use Bobby Fischer's page as example here.
I would like to not see Fischer's page on Recent Kibitzing Page
Or if another big debate broke out on Grand Prix 2015, and I want to block out that page a few days.
How easy would that be?
|May-25-17|| ||chessgames.com: <how easy it is to implement...> I sympathize with what you're trying to do but I can't think of any easy way to accomplish that.|
We have some built-in hooks to satisfy that kind of desire, like most of us know that Rogoff doesn't show up in the recent kibitzing, and little favors like that. But to make it completely invisible from all possible lists, that would be quite a trick.

You've been baking <offramp>'s recipes? You are a hearty fellow...

Honestly, it sounds like <WannaBe> wants to be pampered in his old age.
I'm not judging, mind you.
|May-27-17|| ||chessgames.com: Today's Special on the Opening Explorer menu: Fried Liver with Stockfish!|
(Seriously, look at those deep two-hour evaluations.)
|May-27-17|| ||Bratek: http://torneocapablanca.inder.cu/Ho...|
|May-27-17|| ||morfishine: Old age is nothing
|May-28-17|| ||Richard Taylor: I've used the evaluations up to a point where I see them. They seem to be quite a number of ply deep. I added a couple of notes and the point is that if someone else goes there they can check it say on another computer or they can take note and play what they would want to play.|
That is always the case. A human useful eval doesn't always=computer eval.
But it is a good feature on the OE.
I also found that in one var. there was a new move found by the computer.
But everyone has to remain skeptical...Stockfish as said above will find blunders or obvious mistakes that sometimes GMs play at the highest level. Although I would say that would be rare, mostly - those cases - are lines not so much on the main menu but they might be "back up lines"....
|May-28-17|| ||chessgames.com: <I've used the evaluations up to a point where I see them. They seem to be quite a number of ply deep.> We try to run the evaluation engine longer on the most important positions but have also run it on some famously complex variations. |
Also, when the Opening of the Day comes around, we sometimes try to schedule a few 2-hour evals before it goes online at midnight.
<I also found that in one var. there was a new move found by the computer.> Those two-hour evals often come up with that. For example yesterday we had Ruy Lopez, Closed, Smyslov Defense (C93) found here:
The computer concluded 10.♗c2 is the best move, after 35 ply (2 hours), in spite of it never being played in 488 games. (Seems a little odd, since 10.♗c2 is so thematic in those type positions.)
Currently we're in the middle of a 24-hour evaluation of the starting position. The results of such a scan don't really mean much, but people find it amusing. What will be the very worst of the 20 opening moves? Does 1.b3 instantly equalize or does White retain a tiny advantage? Check back in about 10 hours and find out.
But the real fun hasn't been revealed yet. Soon you'll be able to schedule your own evaluations not only on any Opening Explorer page, but for any move in any game in the database, or even for an arbitrary FEN string.
|May-28-17|| ||morfishine: At a certain stage, its all pattern recognition, thats the point of learning with regards to chess|
If one cannot learn or retain, then one should not be playing chess
|May-29-17|| ||zanzibar: <<morfishine> At a certain stage, its all pattern recognition, thats the point of learning with regards to chess>|
That's exaggerating a little, imo, not giving calculation its rightful due.
* * * * *
I still think some of that processing power should be used to plow through interesting games and - like doing a blundercheck - dropping in alternative lines at points where the engine sees a much better line than that played.
|May-29-17|| ||thegoodanarchist: Hi chessgames.com!
When will you roll out the world championship page for Carlsen-Karjakin?
It's been over 6 months now, and the last one in the list is still Carlsen-Anand:
History of the World Chess Championship
|May-29-17|| ||thegoodanarchist: Er, I mean, add the link for it in the History page.|
|May-30-17|| ||Tabanus: <CG> Add World's Youth Stars (http://somovsmemorial.ru/en/)? Games are here (if it works, and one game is <2200 for both players):|
