What is this new feature?

I don't know about a stockfish version for Go, isn't it Leela, it's estimation is quite near on the games where I had Leela to play.

Also for chess, having the estimation of best network of Lc0 would be very nice.

On what hardware have these estimations taken place?

Is this feature for members only?

I guess it's just for members.

What does the feature do?  Maybe it will be good enough to push me into becoming a member. :)

To try to answer your question, Richard would be the one to answer, but he gave me a few elements:

- for chess he is using Stockfish 9 and it takes about 2 hours,

- for Go he is using Leela Zero (I don't know which network) and it takes about 6 hours !

Here are examples of displays you find as comments of your game,

For 1st move:

And then on each move something like this:

Richard also intends to add graphs, like the ones you get on Lichess

How can be a blunder the best move?

Crelo, did you or brownale ★causethis game to be analyzed?

 - or in other words:  What made this game, in particular, get analyzed?

I'm sorry I can not yet answer your question (yet?), maybe there is no answer (other than to call it a blunder and “the best move” is an error), but hopefully somebody will have a good answer. :)

I think the quality of the move is off by one move from the move listed.

Also, I think go has a few odd display issues, not related to the actual engine.

Chess seems more stable/developed.

But overall, I like this feature.

A better explanation of my first sentence.  In the example given above, “Excellent” refers to the previous move, while “Best move: G4, Your move: E2” refers to the current move.

@Sighris, brownale is a member, I am not, so probably he caused this analysis.

@WIlliam Fraser, indeed, the excelent / blunder seems to refer to the previous move. This way it makes sense.
