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:
“The reasons you allege do more conduce
To the hot passion of distempered blood
Than to make up a free determination
‘Twixt right and wrong; for pleasure and revenge
Have ears more deaf than adders to the voice
Of any true decision.”
—William Shakespeare (1564–1616)
“Happy the man who has been able to know the reasons for things.”
—Virgil [Publius Vergilius Maro] (70–19 B.C.)
“Scepticism is an ability, or mental attitude, which opposes appearances to judgments in any way whatsoever, with the result that, owing to the equipollence of the objects and reasons thus opposed we are brought firstly to a state of mental suspense and next to a state of “unperturbedness” or quietude.”
—Sextus Empiricus (2nd or 3rd cen., A.d.)
