Pretty sure this should count? Haven’t actually used it, but seems to be an option for a free trial account https://decodechess.com

@0482 ?

Sorry, didn't see this comment. I'll check this soon when I get the time, it sure promises a lot but we'll have to check

I tried a position from a game of mine

The results are underwhelming. It points out to "threats" that does not exists, give unreasonable variants as reasons and generally does not give coherent explanation for the move.

We'll have to wait further on this one.

This is not fully free (They give 1 free review a day), but https://www.chess.com has a Review

feature which is very similar to what you want. I'm not sure whether it's an AI, but it does explain chess move logic.

@bohaska interesting. Can you share some examples for how it looks like?

@0482 Sure!

It can be better, but we're 90% of the way there already without LLMs.

@bohaska this is really cool and promising. Too vague sometimes for actually settling the question, but definitely a sign of the process

The strongest argument against this happening is that once you build a system to extract human-comprehensible information from the search tree, presenting it as just plain text seems highly suboptimal

It would probably make more sense to build an interface that combines text description with visualization's of selected lines/positions from the search tree + allows you to ask questions like "why doesn't this move work here?". Overall more of an interactive exploration/conversation based on the tree...
