is there a separate forum for stockfish analysis?i'm still confused about it's usage.
for
L Steiner vs Koblents, 1937
how does anyone know that there is analysis at specific moves? also, do you cache the analysis on a per-game basis or per-fen? if the latter; is it in one ginormous SQL (ala opening explorer) also, can one access one's own previous analyses? |

| Nov-17-17 | | zanzibar: Being a bit curious, I tried to look up a little more info about live.followchess.com. Here's some stats about the website:
http://followchess.com.hypestat.com/
It's a low volume site from Mumbai India.
There's also some technical(?) discussion about the site here: https://stackoverflow.com/questions... I think it maybe first showed up in 2014 (at least on Wayback) http://web.archive.org/web/20141217... . |

| Nov-17-17 | | zanzibar: BTW- just for the record, I think
<Chamitoff, Flight Engineer and Science Officer Greg> should be shortened to
<Chamitoff, Greg> in the PGN. I think I commented over on his page about this - after all, we normally don't carry honorary titles in names (so, it's <Tarrasch, Siegbert> and not <Tarrasch, Dr. Siegbert>). |

<is there a separate forum for stockfish analysis?> Sorry, no, but maybe there should be.
<i'm still confused about it's usage.> Don't blame yourself, the documentation is lacking. But just to make sure you've read what precious little there is, not only does Premium Membership Help Page mention how to use some basic functions, the Analysis Laboratory has a <NEED HELP?> area where you can click and get a multi-paragraph explanation of some details. <for L Steiner vs Koblents, 1937 how does anyone know that there is analysis at specific moves?> It doesn't show which moves have analysis. The opening moves surely will have analysis, later in the game it depends on whether anybody requested it. If the entire game is analyzed it will say "COMPUTER ANALYSIS OF THIS GAME IS AVAILABLE [CLICK HERE]" and you'll find that there is not only a Stockfish "annotation" of the game but also if you pull up any given position and click the "ENGINE" link, analysis pops up immediately. (The fact that there is no wait is the clue that it's been precomputed.) <also, do you cache the analysis on a per-game basis or per-fen? if the latter; is it in one ginormous SQL (ala opening explorer)> Good question. It's on a per-FEN basis, and that table is indeed ginormous, although we trim it back sometimes by removing very short (6/15 second) evaluations when they become older than 30 days. However, when an entire game has been analyzed from start to finish, a special "Stockfish annotation PGN" is stored alongside the original PGN. There are some interesting consequences of this technique. For example if you analyze an entire game it can take hours before you get the results back. Now if you take interest in one specific move, you can go analyze that move (FEN) for an hour. Now go back and request your full-game analysis. It doesn't take hours, it takes a few seconds (sometimes less than a second!) — it simply takes your new analysis and integrates it into the annotated PGN. You aren't even charged Fuel for the second full-game request since the system didn't need to call Stockfish. <also, can one access one's own previous analyses?> The last 30 days appear on your Analysis Laboratory. Incidentally, if you have a customized chess menu at the top of the screen, you might consider going to the Menu Configuration Page and adding the "Laboratory" link. |

| Nov-18-17 | | zanzibar: <chessgames> wonder if you ever considered volunteers submitting their own Stockfish analyzed games from home for integration into your DB. That way you could farm out CPU cycles on a global basis. Hmmm, ...

| | chessgames.com: <Timi> Thanks for the suggestion — I loved it when I first saw it — but as is often the case, it doesn't seem to stand up to computer scrutiny: Kramnik vs Kasparov, 2001 - analysis of move 24.? |

| | chessgames.com: <zanzibar> We've considered doing it on a FEN basis, e.g. Random Visitor can "donate" one of his astounding 50+ ply searches of some opening position or famous game position. Then we replace whatever analysis we have with his. Of course I trust RV implicitly but how to prevent trolls/jokers from uploading bunk analysis? I suppose it could be doled out on a individual basis, sort of like Chessgames Editor status. |

| Nov-18-17 | | zanzibar: <chessgames> tagging the contribution by registered user name with timestamp should be sufficient. A user flag would allow users to filter out such contributions, at their discretion. If someone abused the system a simple reporting mechanism should be sufficient to allow a quick scrubbing of bad contributions. I'd anticipate that > 99% of the contributions would be from <cormier> and <AylerKupp> anyways! |

|
| Nov-22-17 | | zanzibar: <whiteshark>/<chessgames> OK, suppose you put all the games into the same PGN Event tag of <Chess.com Speed Chess Championship> How do you then differentiate the various phases (i.e. time controls) of the match. I think I looked at the PGN, and no see the time control tagged. Will you use a compound round number? But then where will you document the convention used? . |
