Adding Lichess Evaluation for chess960

[QANs12]

This is something that is needed for your Botli. When stockfish play with its normal evaluation on a normal/ low computer, the opening gets worse and much worse during the midgame.

The solution for this I thought was adding lichess cloud eval to chess960 just like for standard games.

If this becomes successful, I think it can help the stockfish to play in a stronger manner.

Lichess cloud eval works only for the first move.

Have you checked if Lichess really has a cloud evaluation for the following positions? It is usually the case with 960 that Lichess only has a cloud evaluation for the start positions.

here https://lichess.org/api#tag/Analysis/operation/apiCloudEval I think We can get cloud eval for any variant

[Torom]

That is not the point. BotLi uses this endpoint for cloud evaluation. I just assume that Lichess has no evaluation for the position in question. Please post the link to a game where BotLi plays only the first move from the cloud.

I went through this as well it shows variants are available which means chess960 too. Can you tell the py file where cloud eval thing is there?

Okay, these are the cloud evaluations for this game:

start position:

{"fen":"nnbrkbqr/pppppppp/8/8/8/8/PPPPPPPP/NNBRKBQR w KQkq - 0 1","knodes":27674,"depth":26,"pvs":[{"moves":"f2f3 a8b6 d2d4 f7f6 a1b3 g8f7 e2e4 d7d5 b1c3 d5e4","cp":67}]}

after move 1. f3:

{"fen":"nnbrkbqr/pppppppp/8/8/8/5P2/PPPPP1PP/NNBRKBQR b KQkq - 0 1","knodes":909,"depth":21,"pvs":[{"moves":"a8b6 d2d4 f7f5 b1c3 g8f7 a1b3 d7d6 e2e4 e7e5 d4e5","cp":62}]}

after move 1... Nb6:

{"error":"Not found"}

So as you can see, it's not because of BotLi that no more moves are played from the cloud. The cloud simply has no more moves in further positions.
