We've recently unlocked a very important facet of our new Stockfish integration, something we call the Analysis Laboratory.

From your own private Analysis Laboratory you can request quick or long evaluations of positions based on FEN or PGN.

Meanwhile, the game pages will now display buttons (to premium members) which allow access to similar features.

Just for example, if you wonder what would have happened if Reshevsky took Fischer's knight in Fischer vs Reshevsky, 1958 from this position

You can click on <COMPUTER MOVE ANALYSIS> and then enter "11...Kxe6" on the move/variation field. After a short wait you'll get the answer:

<1) mate-in-6 (20 ply) 12.Qd5+ Kf5 13.f4 Nc6 14.g4+ Kxg4 15.Qg2+ Kh4 16.Qg5+ Kh3 17.Qg3#>

You can do the same thing for entire games, although of course that will take much longer. When a game is fully analyzed by Stockfish a note will appear under the diagram <A COMPUTER ANNOTATED SCORE OF THIS GAME IS AVAILABLE. [CLICK HERE]>.

If you prefer to see Stockfish analysis in all games that contain it, you can go into your Preferences Page and choose the option <Show computer annotations when available.>

A like that reads "Laboratory" is now a default setting in the customizable menu-bar at the top of the screen. However if you have already customized yours you might want to visit Menu Configuration Page to activate it.

This is a brand new area of the site so regard it as a "beta test" for the time being. You can read more about it here: Premium Membership Help Page.

When I saw an extraneous request to evaluate a game I was confused and canceled it — so that means somebody out there (no idea who) asked for a full game evaluation which was terminated by myself. I'm sorry about that. Try it again and it will work.

Khalifman vs D Yuffa, 2016 [analysis]

How difficult, it would be, to have an analysis (time remaining, or time progressed) clock? I know mine was only one minute, but if someone put in for 5 or 10 minutes, and lose track of time...

If I go to the laboratory page: Analysis Laboratory I see my (1) Position Analysis 1996 Fuel, (2) Game Analysis 1996 Fuel, (3) Move Analysis 1996 Fuel.

If I go to a game, say: I Nepomniachtchi vs Svidler, 2014 then Full Game Analysis, I have 637 Fuel. And the drop down only option is 'intensive evaluation' regardless if I select 1, 2, 4 Fuel/move

Here's how it works:

If you go to a game page, and choose an analysis, the results will be shared with ALL members, for all perpetuity. Because of this, we decided it shouldn't be a "matter of style" which setting you request. All shared analysis is "intensive."

The options have these meanings:

<Intensive Evaluation> — only comment when the evaluation changes more than 0.5 points. (Also provide an evaluation number on any move following a comment.)

<Broad Evaluation> — only comment when the evaluation changes more than 1.0 point. (Again, also provide an evaluation number on the move following a comment.)

<Blunders Only> — only comment when the evaluation changes more than 1.5 points. (And the move following.)

<Annotate Each Move> — is only a slight misnomer; it makes a comment any time the #1 chosen move is not picked, or if a move is played regarded as at least 1 centipawn worse than its computations.

So that's the difference: if you go the official game page, you are sharing your analysis. If not, it's just for your personal review. Note that you can paste in PGN from a famous game into the Full Game Analysis, but you can also paste your private PGN, say from a personal game. This is the first time that you'll be able to see your own game on CG without going through the bureaucracy of having a game uploaded.

Also note, that regardless of whether you choose "Each move" or "Blunders only" or anything in between, the same computation time (and therefore the same Fuel) will be used.

What this means is, over time, more and more games will be annotated by Stockfish, both by the administration and by the members. You can currently see the list here:

games annotated by Stockfish

Because we never want people to replace good analysis with superficial analysis, the system will not allow you to do an analysis that is quicker than the one already in the database.

We know that a lot of people don't want computer evaluations, or at least don't want them foisted on them, so we do not automatically show Stockfish's opinions when you visit one of those games. However, some people might actually want that, so to accommodate we added a new preference option on your Preferences Page that reads <Show computer annotations when available.>.

BTW another feature related to the Analysis Laboratory is the new preference option <Use figurine notation (♔ ♖ ♘ etc.) where possible> — when you select that it won't do very much, but it will present some of the Stockfish analysis in figurine style.

1. I actually despise or actually hate figurine. Prefer just plain old letters.

2. I plugged a PGN game of mine, and the analysis was: hahahahahah hahahahahah hahahahaha

From the docs at Analysis Laboratory —

<We have programmed our game analysis feature to partially endorse Hübner's approach (https://en.wikipedia.org/wiki/Chess...) in that

<There are no exclamation marks, as they serve no useful purpose. The best move should be mentioned in the analysis in any case; an exclamation mark can only serve to indicate the personal excitement of the commentator.>

We should do that, yes. For the really long evaluations, the way to eat popcorn and wait for the big countdown is to go to your Analysis Laboratory and look at the descriptions next to the jobs you're running:

I'll be playing in this tournament starting Monday. (Approx Tuesday in the US).

[You may also wish to list and the recent George Trundle Masters (one day to go) listed on the same site which had quite a few GMs IMs and FMs and I think the PGNs are all available. Gordon Morrell played in the Qualifiers section. He is a member here or was. He is from Canada but has lived in the US as a History Professor.]
