More helpful comments in game analysis

[dav1312]

When a user requests a computer analysis, add more comments to the game to help the player undertand their mistakes

The comments can be added when:

• Allowing a forced checkmate
• Leaving pieces hanging
• Allowing a fork
• Allowing discovered attacks
• Allowing a piece to be kicked
• Incorrectly developing pieces or not developing them at all

Currently if you hang a piece the system will mark your move as blunder, so you can just check this move to get the detailed information.
It is not easy to determine the problem that causes the blunder, so for me its better to just go for such move and check it manually.

It sounds pretty easy to determine what caused a blunder because the engine tells you why
If the eval drops and the engine suggests to capture a piece, there you have it... same for the other suggestions
Lichess already tells you if you allowed or missed a forced mate, so adding more comments sounds like an obvious next step

[pokoli]

Yes, it is something easy to do manually but seems not so easy to do pragamatically.
For example, we may run the lichess puzzle tagger to analize the possition and leave a comment with the detected theme which requires a separate process just to leave a comment on the possition. So probably not worth its complexity.

Did you have a better idea to implement it?

requires a separate process just to leave a comment on the position

I'm guessing that this is very computationally expensive right?

actually is there's a way to train an AI to commentate just like what chat gpt do
just asking..
