Firstly White drops a Maharadscha, that is a piece which moves like a queen or like a knight (also known as Amazon) on the board, on a field where it can not be captured. Than all rules of the normal chess game apply.
 
The objective of White is to checkmate Black, the objective of Black to capture the Maharadscha.
 
 
This game is not balanced, but a good trainee method to see what good development makes and to see how to defend the own pieces. I recommend, take Black and attempt to win against Zillions.
