No moves are available with custom positions about react-chessboard

[Manukyanq]

Hi, react-chessboard package is UI library only and does not take responsibility for chess logic and move validation.

You use chess.js library which strictly uses classical chess game rules and in classical chess game { a7: "wP", b8: "bP"} is illegal chess position, because in classical chess game black pawns start from 7th line and can move only forward to the 1st line.

try to check first is your position valid or not with game.validateFen(fen)

In my opinion its better to open issue in chess.js issues section. Hope I've helped you.

Hi @Manukyanq

Many thanks response.

I saw with position prop we have a BoardPosition type. May I ask how we can use it (could you show example code). At the moment I make an example like the screenshot bellow with an expectation that the king can move & capture the black rook but there is no move available.

My idea is render some custom positions to the board and play around but don't know how to do that. For now I can only using game.fen() for position prop.

Thank you very much.
