extra passed a-pawn in R+4:3|| aka <Randmehrfreibauernturmendspiel>. Spell it!
In comparison with similar endgames with extra a- or b-pawns, an extra c-pawn occurs less regulary (c-pawns are more likely to get exchanged in the opening or middlegame).
Leko vs Korchnoi, 2008 As you can see in the video Leko's king is on f4. So he'd moved <61.Kf4!>, needless to say the best move in the position.
And it was the final move! Korch resigned (in his typical way?), but they made a few more moves - kind of short post mortem line. Thus the confusion with the gamescore.
one side has a majority ∞ sometimes.
Game Collection: Rook endings with Pawns on just one side. : This type of endings when one player has an extra Pawn in Rook ending but all Pawns are on the same side of board is under normal condition (i.e. no trapped Rook or faraway and cut King) drawish and many players consider it as easy task. But in practice we can see that even super-GMs can slip and lose in this situation like Geller with Fischer in 1970 or Duras against Niemzowitsch (see Duras vs Nimzowitsch, 1912 and Geller vs Fischer, 1970). This collection should provide some material for study of this type of endings played by strong players through the chess history.
The rook endgame three versus two on the same flank is the little brother of 4 v 3. The difference favours the defender as there is one pawn less that in the similar endgame.
These endgames are usually drawn and the defense is relatively easy. The good things remain good here as well, such as <the optimal set-up>.
However, thanks to the fact that there are less pawns on the board, the weaker side can also adopt different defensive set-ups.
Even a cramped position should not bother the defender, as long as they can liquidate into an endgame with small number of pawns (one or even two extra pawns for the strong side). These endgames are usually theoretical draws.
From the sample above one can easily figure out the second main danger. It is the king getting cut off from his pawns. In this case they will either be lost due to the combined efforts of the rook, king and pawns; or the defender will have to allow a pawn endgame.
