No word on the app yet?

  chessgames.com: <No word on the app yet?>

Actually there is. One of the programmers went MIA and the project was shelved for about year but just recently the team has reassembled with a replacement, a very sharp programmer, and we're meeting regularly (via teleconference) about the progress made. Some team members think we can get a beta test out in a few weeks while others have a longer (more realistic IMO) timeframe.

So the short answer is, "Yes, we hope to have an app soon." It will first appear in the form of an Android app but an iOS app will soon follow. (The delay will exist only because of Apple bureaucracy that is absent in the Android world.)

Keep in mind the app will not be a generic chess database app that interfaces with CG, it will be a mobile playing platform called the "ChessGames PlayZone."

Meanwhile I'm working on making the site itself more mobile friendly, one page at a time. Right now I'm working on a mobile-friendly advanced search.

  Domdaniel: As the 'improved' So bio is in the news, has anyone else noticed that Wes is described as both 8th and 9th youngest Gm in its early lines?

Hats off to <Chessical> and our <Webmaster> for trusting such stout historians to produce this improved bio:

Wesley So

Still no mention of his connection with <Szuza> though.

Maybe it's not actually important enough to include, but I'm almost entirely unfamiliar with that detail in his career. Others, though, have said it should be included.

  zanzibar: <CG> in the master tournament list, which is a list of years:

Tournament Index

Would it be possible to arrange it so as not to split any year over two links?

A small convenience, to be sure, but I hit it oh-so-often.

  chessgames.com: <Would it be possible to arrange it so as not to split any year over two links?> We could do that only if we gave up on the current "50 events per page" format.

Perhaps we could switch to a year-by-year format, but that gets a little odd looking for some of the older years.

Do you know that if you search on a year it will pull up all of those tournaments? So if you are looking for a specific year that feature wouldn't really be needed.

  offramp: I think there is going to be a time in the future when chess broadcasts cost money. I think chessgames.com should be showing more live broadcasts now, while it is cheap or free.

There is nearly always a tournament going on somewhere, I think you should show one of them.

I have already complained to the chessbookie about the tectonic pace by which new funds arrive. It used to be one thousand tal$ a quarter, now it is 2000 tal$ for users, but I asked for the periods to be months or two months.

Ah, so the lists are generated on the fly?

I overlooked that obvious strategy.

<Perhaps we could switch to a year-by-year format, but that gets a little odd looking for some of the older years.>

To tell the truth, I think the 50 items/page, while convenient for the software generator, isn't that useful for users.

I'd prefer having variable length grouping - but with more obvious years.

E.g. 100-year or 50-year or 25-year or 10-year or 5-year or if absolutely necessary 1-year groupings.

Of course, there should be some max items/page that determines the size of the chronological interval.

BTW- this would be a very natural place to introduce navigational indices with backlinks.

<Do you know that if you search on a year it will pull up all of those tournaments? So if you are looking for a specific year that feature wouldn't really be needed.>

I might have known about this at some point, but I stopped using it. Somehow I thought it easier to just click, scroll, click.

I relooked at the search feature, and might comment on some of the quirks which come up.

  chessgames.com: <offramp> I think you're right. I can't imagine how places like chess24 can afford live GMs to give away free broadcasts unless they expect that to be advertising for a future pay-per-view offering. So let's make hay while the sun shines. I think we'll start covering Shamkir after the break day.

In other news, <Stockfish> showed me a very interesting anomaly today. After going through some 17,000 Opening Explorer positions it plunged to depths of 35 ply at times, with hundreds in the 30s, but one particular position broke all records with 105 (!) ply. The position was this:

Funny little variation, you can see it at the Opening Explorer.

  zanzibar: <chessgames> what do you mean 30-ply vs. 35-ply vs. 105-ply?

What criteria are you using?

(E.g. most searches are fixed time, seeing how deep the engine gets, or fixed depth, allowing the engine as much time as needed.

I assume you aren't doing a fixed-time search, so what exactly are you doing?)

  kingscrusher: Hi Chessgames.com

I quite like the Iphone mode for the site - except one little issue - when trying to see the "latest kibitzing" for a famous player, one has to scroll past sometimes a tonne of bio information. Maybe in Iphone mode, the bio stuff should be somehow optional.

Cheers, K

Apr-26-17  Aurora: Hello <chessgames.com>,

The <32nd Reykjavik Open (2017)> ends tomorrow.

It's a 10-round Swiss tournament taking place in the Harpa Concert Hall in the Icelandic capital from 19-27 April 2017.

The event gathers together 266 players, including 2700 players Giri, Andreikin and Jobava. The top prize is 5,000. The time control is 90 minutes for 40 moves then 30 minutes to the end of the game, with a 30-second increment from move 1. Draws offers are not allowed until move 30. There are no rest days but players can take one or two half-point byes in the first seven rounds.

  chessgames.com: Hi Aurora, we finally got it online (missing a few games) Reykjavik Open (2017). We'll get it cleaned up soon. I think there's a round taking place right now so we'll let the dust settle and see what we've got.

  chessgames.com: <zanzibar: <kingscrusher> there's the <kibitzing> button on the top-right which at least allows jumping over the bio stuff with just one click.> Yes, that's the point of that button entirely. It somewhat confuses new phone users because the kibitzing link on the desktop version takes you to an entirely different page.

<WannaBe: On my Android phone, I hold it upside-down, and it scrolls to the latest kibitz'n!! =))> Now that's a little bit of serendipity! On my iPhone all I get is an upside down chess board that quickly rights itself.

<zanz> <what do you mean 30-ply vs. 35-ply vs. 105-ply? (E.g. most searches are fixed time, seeing how deep the engine gets, or fixed depth, allowing the engine as much time as needed.)>

We only use fixed time searches (in fear of somebody asking for an unrealistic depth for a certain position) but then we record the number of seconds processing, and also take note of the depth that it explored. This way we can reprocess positions only if the new reprocessing is longer/deeper than the previous attempts.

So depending on the complexity of the position (i.e. the number of possible moves in the various ply) a 10-minute think could leave us anywhere between 25 or 35 ply ... but in that one aberrant case where a perpetual was forced, it peered all the way until the 50 move rule started to take effect. I just thought it was an interesting artifact of how computers process chess moves.

  WinKing: In the Reykjavik Open 2017 Giri has 6 wins & 3 draws for a score of 7.5/9. There are 10 players tied for 2nd thru 11th with scores of 7/9. Giri needs a win in the final 10th round to secure 1st place in the Open.

  zanzibar: <<chessgames> This way we can reprocess positions only if the new reprocessing is longer/deeper than the previous attempts.>

Not sure what you're saying here.

You know the processing, so it's only dependent on when you want to devote more processing time for a reprocess, right?

(I'm not understanding something here, I think.)

<i.e. the number of possible moves in the various ply>

This is confusing, a ply being just a 1/2 move after all.

And then this: < but in that one aberrant case where a perpetual was forced, >

The engine normally recognizes a perpetual long before the 50-move rule and drops the eval from some small advantage to 0.00 accordingly.

But maybe not in this case? OK, let me run SF8 on my local machine from the position to see if I can catch a hint as to what you're suggesting.

It seems to me that you're saying the eval was finite until you ran long enough to get to 100-ply (aka 50-move limit)?

That's a crazy depth to run to for any opening study, wouldn't you agree?

  chessgames.com: <WinKing> My mistake, I didn't realize there was a final round today. Good luck to Girl!

<zanz> <This way we can reprocess positions only if the new reprocessing is longer/deeper than the previous attempts.> <Not sure what you're saying here.>

What I'm saying is that we keep track of the analysis of various positions, and when we're done we record the analysis itself, but also the number of seconds it took to get it, and the depth (in ply) that we achieved. That way if we ever want to reprocess a position, we'll only do it if we do it for more seconds, in hope of getting a more thorough analysis.

For example, today's Opening of the Day, the Richter Attack:


click for larger view

The Opening Explorer will show that we've done a ridiculous 1.5 hour analysis of it to achieve a depth of 33 ply.

If anybody wants to delve deeper into that position, it should be 2 or more hours. There's no point in doing a 30 second evaluation if we already have a 90 minute eval.

About 100 of the most popular opening positions have all been analyzed to depths of 30+ ply, at 30 minutes each.

The "biggest think" was on the starting position: it's been analyzed for 6 hours, just for fun. It turns out Stockfish agrees with Fischer: the best move is 1.e4. You might be surprised at what it thinks the next best moves are.

<It seems to me that you're saying the eval was finite until you ran long enough to get to 100-ply (aka 50-move limit)? That's a crazy depth to run to for any opening study, wouldn't you agree?>

It instantly realizes it's a draw (just like any human being would) but if you tell it to analyze it for a long amount of time it will. It won't learn anything new, it will just grind its gears for the prescribed time and continue maintaining it's a draw all the while. I'm not really positive if the 50-move limit came into play there, but the depth suggests that.

I just never knew that engines could produce depths higher than 40 ply without tablebase, but there's one with 105 ply. I found it an interesting exception, that's all.

  SwitchingQuylthulg: <cg> The move numbers in Stockfish's analysis seem to be off more often than not, especially with White to play but sometimes also with Black to play. For example, after 1.e4 e6 Stockfish suggests 4.h3 (!), and after 1.e4 e6 2.d4 d5 it suggests 4.Nc3; but after 1.e4 e6 2.d4 d5 3.Nc3 Bb4 it suggests 3.exd5. That's just one sample line; similar things happen in almost every line.

Opening Explorer is one example where the move number is off with Black to play.

What's up with that? Is this a known bug?
