Rook endings are a very common phenomenon in chess tournaments, since the rooks often are the last among the minor and major pieces left on the board, as the other pieces have already been exchanged. This is why it is important to know the principles of this kind of endgame. One of these being, that the rook works better on a distance; both the distance to the enemy king and to any rook pawn. Another being, that the rook is a very effective piece, when it comes to cutting off lines or ranks for a hostile king. These two principles will be illustrated in this example.
Black is actually able to draw here. The idea for black is to wait for white's pawn to advance to e6, which will happen eventually. While black waits for this, he must keep the rook active on the 6th. rank. When the white pawn reaches e6, black will move his rook to the first rank, and start a perpetual check on this very rank. There is no way for white's king to hide as the pawn occupies e6.
