{[%mdl 32769] The rook's activity is the main principle for evaluation and
practical play in rook-and-pawn endgames. It can take various forms: attacking
the enemy's pawns, supporting its own passed pawns, cutting the opponent's
king off, or pursuing the king. It also happens that the rook must sometimes
behave passively, its functions being limited purely to defense. But in these
cases one should relentlessly seek for opportunities to activate the rook,
even at cost of pawn sacrifices or deteriorated king's position. The following
classical ending illustrates this principle excellently.} {White has an
obvious positional advantage, but as for a win, it is surely a long way off.
