Variants

`MovingPieceNotFound`

Origin square not found for moving piece

`KingIsSafe`

Unexpected king state for the turn

`KingIsInCheck`

Unexpected king state for the turn

`KingIsInCheckmate`

Unexpected king state for the turn

`KingCannotCastleSafetly`

King movement during castling must not be under check

`OurKingMustBeSafe`

Upon executing the turn, king must remain safe

`CaptureNotSet`

Turn missing info about the capture

`CaptureAlly`

Capture of an ally piece is not allowed

`NoCapturePiece`

Capture expected, but capture piece missing on the board on the destination square

`GameOver(Gamestate)`

Game over

`CastlingUnderCheck`

King can castle if it is not under check

`CastlingUnavailable`

Castling not possible

Maybe king/rook has moved already and doing so made castling unavailable

`CastlingSquaresNotEmpty`

Squares between a rook and a king must be empty in order to perform castling turn

`InvalidPawnMovement`

Pawn moves:

diagonally only by capture action
straight in case of no capture action

`ParsingTurnFailed`
