To play you will need one Black Queen, one Black King, one White Queen, and one White King and a number of Black and White Pawns to be decided by the White Player.
White will always go first.
If you do not have a Black Queen, a Black Knight will do. If you do not have a White Queen, a White Bishop will do. If you do not have a Black King, a Black Bishop will do.
The White King must always be the White King.
White will always go first. Black cannot act before White.
This is the Most Important Rule.
