Not all similar positions are wins. In this position, Black draws because he can safely check from the side. For this defense to work, there must be at least three files between the defending rook and the attacking king, and the defending king must be positioned such that it doesn't block the checks; that is, the defending king is on the "short side" of the pawn (the one with fewer files between the pawn and the edge of the board) (de la Villa 2008:127–28). (See the "short side defense" at rook and pawn versus rook endgame for more details.)

Famous quotes containing the words similar, positions and/or drawn:
“We cannot feel strongly toward the totally unlike because it is unimaginable, unrealizable; nor yet toward the wholly like because it is stale—identity must always be dull company. The power of other natures over us lies in a stimulating difference which causes excitement and opens communication, in ideas similar to our own but not identical, in states of mind attainable but not actual.”
—Charles Horton Cooley (1864–1929)
“An ... important antidote to American democracy is American gerontocracy. The positions of eminence and authority in Congress are allotted in accordance with length of service, regardless of quality. Superficial observers have long criticized the United States for making a fetish of youth. This is unfair. Uniquely among modern organs of public and private administration, its national legislature rewards senility.”
—John Kenneth Galbraith (b. 1908)
“the hunger of this poem is legendary
it has taken in many victims
back off from this poem
it has drawn in yr feet
back off from this poem
it has drawn in yr legs”
—Ishmael Reed (b. 1938)
