Every one of us has heard this phrase at least once in our career. Even though such statements can not be 100% true, they serve as a reference point. Indeed, drawish tendencies in such endings are considerable. That's why before starting my preparation for the current lecture, I was afraid that I will deal with more or less evident stuff. While selecting the material, however, I was surprised to see how often top-level grandmasters lose such endgames.

This was an indicator that things are not that simple. After presenting the basic must-know classical positions, I tried to illustrate some statistically common mistakes. In this way, you will get a complete overview of the possible dangers. While I tried to keep the theoretical overload as limited as possible, I strongly advise you to take a look at my introductory class "Rook and Pawn vs Pawn". In this way, you will be better prepared for this lecture. I hope that the current material will drastically increase your practical level in rook endgames with pawns on one wing.

In this way, White can never create a passed pawn on the e-file. Had the h-pawn been on h2 (instead of h4), the formation of a passed pawn would have been possible. Nevertheless, due to the massive pawn exchanges, the draw would have been obvious.} ({If Black plays a waiting move such as} 1...

He just needs to wait with the rook on the f-file.} * [Event "Moscow"] [Site "?"] [Date "1956.??.??"] [Round "?"] [White "Botvinnik, Mikhail"] [Black "Najdorf, Miguel"] [Result "1-0"] [Annotator "GM Grigor Grigorov"] [SetUp "1"] [FEN "8/1r3kp1/5p1p/5K1P/4PPP1/8/R7/8 w - - 0 62"] [PlyCount "23"] [EventDate "1956.??.??"] [SourceTitle "DEM"] [Source "ChessCafe/CB"] [SourceDate "2003.10.29"] [SourceVersion "1"] [SourceVersionDate "2003.10.29"] [SourceQuality "1"] {Sometimes, however, Black is not in time to reach the favourable defensive construction with Kh7 and Rf1.
