| Apr-06-18 | | thegoodanarchist: <offramp: Hey! Here's a great idea! How about a message saying <"THIS GAME WAS TRANSMITTED LIVE AT CHESSGAMES.COM"> on all games so transmitted? That's only for games in the future It's not backdated, which would be complicated.> Not! A! Bad! Idea!
May I suggest that the message say:
"THIS GAME WAS TRANSMITTED LIVE!!! AT CHESSGAMES.COM!!!! AMAZING!!!" |

| Apr-06-18 | | Big Pawn: A lot of blitz games show up in the database now. I was looking at Carlsen's games with White in the variation 1. e4 c5 2. Nf3 d6 3. Bb5+ and there's a number of blitz results in the 22 games that show up. Doesn't this corrupt the integrity of the opening explorer? Opening explorer shows the win/lose/draw percentages for each move and people use it as a guide, but if blitz games are being included, I think it waters down the integrity of the data. Is there a way to search the database and exclude blitz games? |

| | chessgames.com: <Doesn't this corrupt the integrity of the opening explorer?> If you were seeking purely classical results then you might say it skews the results, but I wouldn't say it's "corrupted." Common wisdom is that in blitz/rapid games, White's advantage is more pronounced and draws are less frequent. You can't always rely on "common wisdom", so I updated the ChessGames.com Statistics Page to see if the statistics support this belief. At the time of this posting, the stats look like this: <<<All time controls (871,110 games)> White wins 328,560 games (37.72%)
Black wins 244,391 games (28.06%)
298,144 games are drawn (34.23%)
<Only classical time controls (790,702 games)> White wins 295,518 games (37.37%)
Black wins 218,772 games (27.67%)
276,401 games are drawn (34.96%)
<Only non-classical time controls (80,408 games)> White wins 33,042 games (41.09%)
Black wins 25,619 games (31.86%)
21,743 games are drawn (27.04%)
> >
So yes, it seems that common belief is supported by evidence. However, on the whole, the effect is fairly small (e.g. 37.72% vs 37.37%). When it comes to looking at the results of a specific player and opening, like you did with Magnus' Sicilian move order, we are almost forced to resort to the method of using all available data, simply because there's not much data to draw conclusions from when you focus on a single player. When examining the entire database, applying restrictions could make sense. Notions of making toggles for "modern games" or "classical time-control only" or "over 2600 rating only" have been suggested before; and all of those ideas have merit.
Until then, in absence of such toggles, I would say that the way we are doing it now is the most useful for the most people, as well as being the easiest to understand. |

 | | OhioChessFan: In major tournaments, such as Grenke, you have a game page for what will be the next day's live game set up a day in advance. In today's case, it's tomorrow's Caruana-Aronian. Why not open a page for all of the games? I know you have the tournament page, but that's mostly talk about what happened already, whereas the other pages might be used to discuss the strategic implications of the various matchups, and so forth. Further, during your live games, there's often talk of "What's going on in _________ (another game)?" It'd be nice to have those available for whoever might want to drop a FEN of that game's current situation. Not too big a deal, the tournament page and live game page do an okay job filling those services, but not quite as directly on topic as the individual game pages would be. |

Use his opening stats at classical time controls at your own peril. |

| | OhioChessFan: I know laboratory analysis is on the enhanced menus, but it seems to me to be individual enough it should show up on as a link on your profile page. |

| Apr-07-18 | | thegoodanarchist: <Including openings Carlsen plays corrupts the integrity of the opening explorer. Use his opening stats at classical time controls at your own peril.> Carlsen has been a disrupting force in chess ever since he drew Kasparov in a blitz game, when he was still a child! |

| Apr-08-18 | | Dr Winston OBoogie: Excuse me. Nuno is posting nude pics of me! Whilst I look great and everything I'd rather he didn't have nude pics of me and to explain how he got them. Thank you webmaster :) |

| Apr-08-18 | | Dr Winston OBoogie: He posted this here then deleted it, Daniel. Told you, he's not normal! <Keyser Soze: Wasn't a nude and wasn't you. A fat and pale guy without a t-shirt aint a "nude"
BE A MAN once inr you life, mark.
hehehe> |

| Apr-08-18 | | Keyser Soze: Leave the site Wiston..enough of your drama. 10 years of whining. I stand correct: Wasn't you or a "nude". And I have testimonies. Leave the webmaster alone bro..
And <you> talking about "normal behavior" is priceless.. How's your legal case going bro? |

| Apr-08-18 | | whiteshark: re: computer move analysis
<ERROR: Sorry, you already have 4 pending analyses. Please wait for some to complete before initiating new ones.> That's because it didn't accept my 4 requests* before on: J A Grefe vs K Commons, 1975 for <13...0-0 14.fxe4> with an unclear and confusing error-message** After 15 mins I retried, but it seems the comp is still busy with it / blocked by the 4 requests. <ceegee> could you please check it? * 1 minute, each

with <13...0-0 14.fxe4> as well as with <13...O-O. 14.fxe4> (although the dot behind 0-0 looks strange) It finally worked with <13...O-O 14.fxe4>, when I used capital <O>s instead of zeroes |
|
| Apr-09-18 | | whiteshark: One last word/fyi: When the computer analysis starts with a 2/+ moves line under http://www.chessgames.com/perl/nph-... it says "Now trying <varation>". |
|
| Apr-09-18 | | zanzibar: <<whiteshark> It finally worked with <13...O-O 14.fxe4>, when I used capital <O>s instead of zeroes> This one (0-0 instead of O-O) is common enough that I've seen several PGN guideline docs mention not doing it, rather explicitly. |

 | | WannaBe: The issue of zero vs capital O in PGN for castling have been covered so many times... CVD have no issue with this, another reason I am sticking with CVD. |

| | OhioChessFan: Not a big deal, but two different pages have two different naumbers: <Feel free to submit another pun. You may submit as many as 100 entries.> <Feel free to submit another pun to this list. You can submit up to 300 entries!> |
|
| Apr-10-18 | | zanzibar: From the PGN standard (online):
<SAN kingside castling is indicated by the sequence "O-O"; queenside castling is indicated by the sequence "O-O-O". Note that the upper case letter "O" is used, not the digit zero. The use of a zero character is not only incompatible with traditional text practices, but it can also confuse parsing algorithms which also have to understand about move numbers and game termination markers. Also note that the use of the letter "O" is consistent with the practice of having all chess move symbols start with a letter; also, it follows the convention that all non-pwn move symbols start with an upper case letter.> http://www.saremba.de/chessgml/stan... A German site, fwiw.
Wiki suggests a confusing dual standard:
<
Castling
<Castling is indicated by the special notations 0-0 (for kingside castling) and 0-0-0 (queenside castling).The notation 0-0-0-0 was once used in a puzzle composed by Tim Krabbé to indicate a king castling vertically across the board with a promoted pawn which had become a rook on the e-file but not yet moved. FIDE subsequently amended its rules in 1972 to disallow this.[5]> While the FIDE Handbook, appendix C.13[6] uses the digit zero (0-0 and 0-0-0), PGN requires the uppercase letter O (O-O and O-O-O). <<>>> And while it's true that the FIDE standard uses the zero digit, the font easily could indicate the letter, and the text doesn't elaborate on the difference: <Essential abbreviations
0 - 0 = castling with rook h1 or rook h8 (kingside castling) 0 - 0 - 0 = castling with rook a1 or rook a8 (queenside castling)>
>
https://www.fide.com/FIDE/handbook/... (See appendix C, and note that most people omit the extra spaces FIDE uses in their example) I agree with <WannaBe>'s implicit suggestion that a parser should be able to handle both inputs, despite the standard's cautions - as it's user friendly. But <WannaBe>, how does <CVD> output the PGN? I assume it picks one or the other, and doesn't randomly choose... so, which is it? |
