Cache SF eval of common opening lines

To engine coders : Could lichess cache evals for 'common' openings and allow that last bit of analysis done on fishnet (the first few moves) to be looked up? I understand the growth rate of the cache is 30^n half moves but the practical openings would be much smaller and misses could fall back to full eval.

I don't think cache is the correct word, but you can actually vote for that feature. :)

"Server storage of local analysis - Contribute with your local analysis (like ChessBase's Cloud analysis). "

this is only cool if it min-maxes

It's done already

So I take it that the 'cloud' word means looked up in a cache.

Brilliant.

Out of interest how big is the cache? I was looking at my games and 1.e4 e5 accounts for 50% of all the games I've played.

The cache is being built by lichess users. Have your local stockfish evaluate a position, then reload the page. You'll see it's now in the cloud; you'll never need to compute it again.

Very nice. But you cannot retain all of these analysis, how do you decide what to discard? Maybe I'll go off and find this is github and see if I can work it out.

I'll just drop evals that have not been consulted for a month, or something.

What about for variants?

I think it is brilliant to store the analysis positions is the cloud! Undoubtedly it saves time and CPU power to analyze. Good job @thibault and the rest of the development team!
