How do you figure out what moves have been played?

How can you find out what moves have been played in a game (like 1. e4 e5 2. Nf3 Nc6 etc.)? Is there a function that I can use?

Doesn't seem to be a function described in the docs: https://seblague.github.io/chess-coding-challenge/documentation/, I suppose you could diff the bitboard states between your moves and infer the move.

@SebLague can you add this feature to the code?

@SebLague can you add this feature to the code?

Lague is most likely asleep currently (its 20 min till midnight in his (and my) time zone). I doubt this will be added as this feature likely has little to no use when creating an engine.

If you want a unique value representing a position use board.ZobristKey

Duplicate of #92 @MathabsUnity seems like you are opening same issue multiple times.

This is actually found in the Board class here: https://github.com/SebLague/Chess-Challenge/blob/20b3556031cca60cdbdd88e4f5e24359bf99e617/Chess-Challenge/src/Framework/Chess/Board/Board.cs#L61. But unfortunately I don't think we can access that class, as it is not specified as public in the Board we can access: https://github.com/SebLague/Chess-Challenge/blob/20b3556031cca60cdbdd88e4f5e24359bf99e617/Chess-Challenge/src/API/Board.cs#L10

If board was public there we would be able to do something like

    public Move Think(Board board, Timer timer)
    {
        List<Move> moves = board.board.AllGameMoves;
    }

but we can't :(

[SebLague]

There isn't currently a way to access this through the api. Do you just need this for debugging, or do you plan to somehow use that info as part of your bot's strategy?

I want to use it in my bot's strategy.
