#3 Kamikaze(8+9)
b) Bishops become Queens
a unit (except the King) that captures disappears ipso facto.
So if a side is more populated, it must have made a capture by the King, and therefore can no longer castle.
Here, Black is 9, White 8. White castling is therefore a priori possible.
Pawns cannot change file.
