- If after a move the King reaches an edge of the board and has an open path to one of the corner squares, the player has to let the opponent know by saying "Raichi!" (like "Check!" in Chess).
- If there are two open paths the player has to say "Tuichi!" (like "Checkmate!" in Chess), because it's not possible to close both paths in a single move.
- If the King is in danger of being captured on the Muscovites' next move, he must say "Watch your King" to the Swedes.
Notify when the player is in check or in check mate.
According to : http://www.irminsul.org/arc/002sg.html
If the King has a clear approach to any edge square, the Blue player announces, "Raichi," or check. If the King has a clear approach to two exit squares, which is unblockable, he announces, "Tuichi," and wins the game since the move can't be blocked in one play.
