Chess castling #18

Open olufjen opened 3 years ago

olufjen commented 3 years ago

We need a method to perform chess castling When all position to the left or right of the King then the king and the rook can exchange places. A suggested procedure: The moved piece is checked for castling. If that is the case then the method returns which castle is involved

31.03.21: For further work see issue Deferred action 12.05.21: Castling works for the white players.

The current castling move: The white player makes two moves !!! and the black Rook occupies wrong position
