Is there a way to get the FEN after every move in a game?

Hello everyone. From my brief experience with the API, I have seen that we are able to collect the FEN of the final position of a game. Is there a way to retrieve the FEN after every move of a particular game? I saw that we are able to retrieve the moves, but not in the FEN format.

To the best of my knowledge no. What you see in the api documentation is what the api provides and nothing more.

Are you able to construct a list of FEN strings from the moves list of a game? I think that's the only option open to you.

I'm not aware of a current API that provides this directly. However, if you retrieve the PGN of a completed game, there are many tools that can help you load that PGN and generate move-by-move FEN strings from the game.

pgn-extract is one such example - a command-line tool for manipulating PGN data. Here is me piping a PGN into pgn-extract and asking for FENs for each move. (Originally saw this method on stackexchange.)

Interesting thought. My initial reaction is 'Why would you need that?'

That's great, rhymeswithgod. Thank you

Tricky_Dicky, this is just an idea for now and a personal project but I plan to feed a bunch of games of players with varying chesscom elo's to a neural network  and do a Guess the Elo type of prediction. I'm interested to see as well some data exploration, like if players from different countries usually tend to play more a certain opening, just to fulfill my curiosity lol. But again, nothing concrete yet

Cool idea

That's a great idea. I think you would be well off with just reading data from complete games. Is there any reason you want to use data from uncompleted games?
