Reasons
The advance of the passed pawn lengthens the range of a rook behind and reduces the range of a rook in front. A rook escorting a pawn from ahead must move off, potentially leaving the pawn undefended, if it is to promote. A rook behind an enemy passed pawn can more readily generate counterplay.

Famous quotes containing the word reasons:
“... to a poet, the human community is like the community of birds to a bird, singing to each other. Love is one of the reasons we are singing to one another, love of language itself, love of sound, love of singing itself, and love of the other birds.”
—Sharon Olds (b. 1942)
“Whenever we approve, we can find a hundred good reasons to justify our approbation. Whenever we dislike, we can find a thousand to justify our dislike.”
—Samuel Richardson (1689–1761)
“In looking back over the college careers of those who for various reasons have been prominent in undergraduate life ... one cannot help noticing that these men have nearly always shown from the start an interest in the lives of their fellow students. A large acquaintance means that many persons are dependent on a man and conversely that he himself is dependent on many. Success necessarily means larger responsibilities, and responsibilities mean many friends.”
—Franklin D. Roosevelt (1882–1945)
