I made a chess website that lets you analyze every move not just the best ones.

@MaxHastings

What do the numbers by each of the pieces mean? I think there should be some kind of a legend. Otherwise how is it different from analysis on lichess?

Start a new game, and use "Assist: Full". Then grab any piece and move it and you will see the values increase or decrease compared to where it was. This tells you if it will be better off to move it there or not.

The numbers next to each piece represents the highest evaluation that piece can make on the next move. So a +13 above a piece would mean that the best move it can make will make you at a +1.3 advantage. or 130 centipawn advanage.

When you select a piece you will see a score on each square that piece can move or capture on. Again each score representing what your advantage or disadvantage will be after making the move.

Blue background represents the best move. Green is a good move ( within 75 centipawns of best move ). Inaccuracies are orange ( within 150 centipawns of best move ). And mistakes and blunders are Red being anything greater than 150 centipawns away from best move.

It is different from Lichess because Lichess and every other computer engine program only will show the best move, the top 3 or top 5 moves. Chess Fish is programmed to show you a score for every move.

Hopefully this explains it well :)

Really nice, well done!

Thank you :D

It's a nice idea! But I'm neurodivergent and holding out for a human coach. 100% against using AI or engines for game analysis here.

Those values are very difficult to understand, and far from what people are used to. As a chess software dev myself, I couldn't figure it out, and the website didn't give any hints, either.

It was obviously not the usual cp that everyone uses, and it wasn't winning percentages either.

I suggest to stick to one of the metrics that people know, so either use "+1.3" or "65 %". There is nothing to be gained by inventing "decipawns", except confusion.

Otherwise, it looks pretty nice.

Yeah I originally had it show centipawn values but switched to decipawns because I felt having a decimal point was unnecessary. I rather see +3 on my screen than +0.3 and whole numbers in general. And maybe later a more mainstream audience that isn't used to the traditional scoring of centipawns would prefer it.

But this could also be an issue since most early adopters are going to be used to centipawn values. so thank you for bringing this up to my attention.

I think not only early adopters. Like everyone sees cp everywhere - every video, every engine, every website.

I do see the charm of integer values, but it is a very high price to pay for a negligible and only visual "improvement". And even if you know what it means, every chess player will translate those values in their head to cp anyway, which seems an unnecessary burden.

There's a reason why we use standardized units, and if we don't, it leads to friction, confusion, misinterpretation. Different temperature scales or length units... what a mess.

Would you think it is a good idea to only write 5, 6, and 10 on road signs for speed limits instead of 50, 60, and 100? ;-)

(I think I have seen a similar feature in the Windows version of Shredder BTW).

thanks very interesting sir.
