... Averbakh's Comprehensive Chess Endings, vol 4, Pawn Endings ...

"I conceived the idea of writing a popular booklet [Chess Endings Essential Knowledge] devoted to the endgame back in the early 1950s, when I was working on an encyclopaedic reference work intended for players of high standard. Out of the mass of information on the endgame, I thought it was important to select the minimum which any chess enthusiast should know in order to handle competently the concluding phase of the game. It turned out that it was not necessary to know such a great deal." - Averbakh

Maybe not necessary but probably sufficient.

The book starts off from the very basics (KPK) and builds up from there, so no particular standard is required to read it.

The booklet referred to was presumably Chess Endings: Essential Knowledge, but I haven't seen it. so I don't know if OP's position is included.

"... As a whole, Comprehensive Chess Endings will be a basic reference work on the theory and practice of the endgame, indispensible for the analysis of adjourned positions and for correspondence play. It will also be useful as a text-book for rated players wishing to raise their standard of endgame play." - Averbakh

MARattigan

It would no doubt be useful to highly rated players. Fischer had a copy of the series sent to him in his match against Spassky.

But it's also a good read and there would be nothing to stop an interested beginner from reading it. He'd have to be interested, of course, because at 300 large format pages for the Pawn Endings volume he wouldn't work his way through all those examples before tea time.

So far as GambitDanois is concerned he'd need to read only the section Two Pawns against One/Connected Pawns/No passed pawn, pawns blocked or even just the text accompanying diagrams 146 and 147.

I imagine there would be a French translation.

Hello everyone, 

I was doing some drills on chess.com and I failed this one. Here, the only valuable move for white is Kg2 if you want to win the game. I know that is about opposition but I can't understand why. 

 

I tried to think about the solution and for me, Ke1 or Kg1 could have been possibilities. But Ke1 is not possible because de e-file is blocked by e6 pawn and Kg1 is possible according to stockfish but only if we come back after to go again on Kg2.

 

I hope someone who knows the solution could explain that to me because I'd like to understand it even if I'm not sure to remind that in a game :'( 

 

Thank you a lot and sorry for my english,

 

GD

1 Kf2 allows 1...Kf8, obtaining a draw for Black.

1 Ke1 or 1 Ke2 also allow a draw. After either move, Black can play 1...Ke8 with the plan to go back and forth between e7 and e8 for as long as White moves his king on the e-file. If White returns to the f-file, Black can also move to the f-file, choosing between ...Kf7 and ...Kf8 in order to get distant (or perhaps basic) opposition on the f-file. If White goes to the d-file, Black can move to the d-file (either square) and be ready to take up distant opposition on the c-file if White proceeds to the c-file. c5 can be answered by ...dxc5, followed by moving the black king so as to be able to block the d-pawn.

If White plays 1 Kg1, then Black can reply 1...Kf7 and how is White going to make progress? If 2 Kg2, then 2...Kg8 and the game is drawn. If 2 Kf2, then 2...Kf8 and the game is drawn. If White moves to the h-file, then 2...Kf6 and, in order to save the c4 pawn, White has to go back to the g-file, allowing Black to take up distant opposition on the g-file and draw the game. After 1 Kg1 Kf7, there is nothing better for White then to go back to f1, and no progress has been made.

1 Kg2 makes progress. For example, if 1...Kf7, then 2 Kf3, winning.

But a single line terminating in a win proves nothing.

Indeed it doesn't, but I think that I understand this particular example well enough to be able to help if there is something specific that you wish to explore. An attempted improvement for Black? An alternative winning attempt by White?

@kindaspongey: I'm OK with it (I've read the book) and your subsequent explanation was reasonably clear too (if less complete than Averbakh's). I was just pointing out that playing a single winning line doesn't explain much.
