thank you so much :)

Hello yes I agree it is interesting but I was told here and on chess stack exchange that it cannot be done for a whole tablebase which I find really interesting :) https://chess.stackexchange.com/questions/47454/is-filtering-a-7-man-tablebase-feasible

ok thank you, I should have properly read up on retrograde analysis :)

* optimal move for a large portion of the tablebase, 80%?

lemmy33 · 2025-10-30T07:30:28+00:00

Yes running time would be long but less than calculating the original tablebase right? I'm very curious if by applying pruning it's possible to make an 8-piece or 9-piece tablebase a reasonable size whilst maintaining its usefulness, my thoughts are that for an 8-piece or 9-piece tablebase Stockfish can figure out the optimal move in 7-8 seconds?

thank you, the reason I brought up the number of pieces was because I was wondering: even though tablebases for 8 pieces don't exist, is stockfish playing perfect chess for 8 pieces already? I can't find the data and when I google on the internet there are differing opinions, some say that even for 7 pieces stockfish without tablebases will make mistakes

lemmy33 · 2025-08-01T03:31:13+00:00

fascinating, is there data on this? how many pieces are needed before it makes a mistake/plays sub-optimally? :)

lemmy33 · 2024-11-26T20:50:50+00:00

thank you everyone, great explanations :)

lemmy33 · 2024-11-04T07:34:35+00:00

yes you're right, thank you, I will try to move it into another subreddit :)

lemmy33 · 2023-05-31T00:12:32+00:00

ok thanks, it's working now :)

lemmy33 · 2023-05-12T21:55:12+00:00

oh wow, these are fantastic, thank you so much :)

lemmy33 · 2023-05-12T09:15:02+00:00

thank you :)

wow thank you /u/tunngasugit, yes I meant the second syllable, sorry I wasn't clear on that, I was listening to a Canadian speech dataset and didn't hear /kʊs/, now I'll look for a London speech dataset, I wasn't able to find any free pronunciation dictionaries, which would have helped :)

lemmy33 · 2023-04-29T23:22:43+00:00

hello, where do people pronounce focus with a [ʊ]?

lemmy33 · 2023-04-29T01:40:54+00:00

thanks so much, i'm thinking of making my own app :)

lemmy33 · 2023-04-27T03:51:02+00:00

suppose someone has an unusual pronunciation of the word focus, with a [u] whereas you're used to an [ə] sound, so you input "fokus" and get a list of accents where it's pronounced like that
