The definition of the Pegasus is incomplete and confusing:
"The Pegasus leaps as a knight and may then slide outward as a rook"
It should be said that "The Pegasus leaps as a knight, one orthogonal step followed by a diagonal step leaping the intervening square, and may then slide outward as a rook on the same orthogonal direction"
For example, a Pegasus on a1 may go on b3,b4,b5,etc. it may not go on b3,c3,d3,etc. which is also leaping as a knight and then slide outward as a rook.
