- White lancers are facing diagonally upward, while black lancers point
- diagonally down in the deterministic initial setup.
- In the randomized version, to avoid complex setup rules,
- all lancers are facing up.
+ Lancers begin aimed toward their destination square of castling.
+ They can be reoriented after castling, if they effectively moved.
+ While castling, some pieces can stand on the lancer's path,
+ since it can jump over them.
