'''[[Main Page|Home]] * [[Evaluation]] * [[Evaluation of Pieces|of Pieces]] * Rooks Rook on (Semi) Open Files'''
An [[Open File|open file]] is usually defined as a file with no pawns on it - a [[Half-open File|semi-open file]] as containing only the enemy pawns. In both cases a rook occupying such a [[Files|file]] gets greater vertical [[Mobility|mobility]] as well as a chance to penetrate the enemy camp, positioning itself on the [[Rook on Seventh|7th rank]].
