Igor takes Viktor to the room with the life sized chessboard. Viktor was a rather famous chess player, so he didn't mind. Igor was aware of this, so he brings in a new piece, a SuperQueen. It can perform all moves of a queen as well as a knight.
Igor gives Viktor 10 SuperQueens and increases the chessboard's dimensions to 10×10 . He then asks for the number of possible ways that all 10 pieces can be placed on the board without coming in each other's path.
