You might be right.
My comment is to the diagram the member wss has made where the pieces are on the following positions.
White.
King g5, pawns f4 & h4, Rook b7.
Black.
King g8, Rook a1.

After 1...Rg1+ 2.Kf6 is a blunder because of 2...Rg4 when one of the pawns will drop resulting in a draw. And 3.Rb8+ leads to nothing.
After 1...Rg1+ white should instead play 2.Kf5 to prevent 2.Rg4
after that black is lost.

Thanks Paddy.  I was not aware of NIC's errata page and have submitted this one.  It was helpful to read the other errors they report there, both in this book and other NIC books I own.  Well done.

Well spotted--the Nalimov tablebases confirm it is won. It's a draw if the Black King has another rank to move in.

Still, I think this book is excellent. De la Villa writes like Capablanca, very clearly and directly.

I have the book and worked over halfway through it by now.

I must say I have never seen a book on endgames so well explained.
De la Villa tries to give "rules" for as far this is possible, many endgames I do understand much easier than before.
Its easy to forget for example after a year or so how a certain rook endgame has to be saved or won, but by these explanations it feels like it is easy to understand.
I think IM John Cox would have said anything else if he had done a bit more than only looking by it quickly in a store and understand why exactly that engame was given.
(Anyway I like most of John's books too   ) 
I rate this book very high and I think it's a "must buy!".
I have the endgames dvd's by Karsten Müller which I found very good but this book makes it even more clearer.

I once was rated 2300+, now its about 2100 because I didn't play much but I think it's good material for 18/1900 up to even 24/2500.

You can study a lot of openings which can become "outdated" but these important endings de la Villa discusses certainly don't!

A review is on ChessCafe: http://www.chesscafe.com/text/review645.pdf

This is the best practical endings book which I own. 

Much more better than Makarov's and much much more than Silman's "Endgame Course".

I opened this in a shop in a very desultory way and found the choice of endgame surprising. I only really looked at one example - N & P -v- B, with the defending king far away, and talking about how long a diagonal the bishop needed. The example given was nice and clearly explained, but I just imagined that there would be more than 100 endings you'd need to know before this one. Maybe I'm wrong. Not really a criticism - it looked nice enough based on my very cursory look.

(Well, from the above mentioned download you get absolutely
NO idea what kind of endgame book it is. Shame on NiC!)

I´ve got a copy and I like this book very much!   8-9 stars (out of 10)

It contains far less material than Fine, Dvoretzky or Müller/Lamprecht 
(depending on your wishes you can see this as disadvantage or advantage: 
at least you don´t shy away from the sheer volume).
It´s not about all theoretical endgames but only about the "exact" endings. 
That means reduced material, very few pawns:
R+PvR, R+2PvR, RvP, Mp+PvMp, R+PvMp, NvP, QvP, QvR+P,
R+BvR, B+2Pv#B, Pawn endgames with 1-3 pawns, ...
(the breakthrough 3Pv3P is the example with most material!)

Okay, you can debate about the choice, but de la Villa is obviously
a very good&experienced player/trainer.
And these "100 endgames you must know" are surely a very good
start before you delve into endgames with more material.
(The only endgame I really miss is the classical R+4PvR+3P with extra pawn 
on the other wing. Maybe not an exact ending, but VERY important!)

You now might get the impression that this book is a primer, but no, it isn´t!
Imo it´s adressed to club players of a ~1600-2300 level, who have the usual knowledge 
and practical experience in some endings, but have never really studied 
endings in depth.

There´s a list/recapitulation/test at the start of the book, any 1600 player should 
be able to know/solve that. Then 100 endgames (enhenced with little exercises). 
At last the real test (with some quite difficult questions for an expert player like me)

This endgame book is no complete reference and you really have to work with the book.
But it´s very didactical. I think it´s more understandable as even Dvoretzky, I´m just 
fascinated by the clear explanations about the more difficult exact endgames 
(like R+PvMp or B+2Pv#B).

Maybe it´s no must-buy, if you already have Dvoretzky or Müller/L. and really work 
through 400++ pages. But for most practical players below master level 
it offers the probably more effective alternative to study the really important
100 endgames better and faster. And to use the complete endgame book 
on the book shelf only for more referential purposes or for some
more complex endgames.

Edit:
Maybe even improving 1200+ players (who know the basic mates) can use this book as introduction,
but it is obviously more designed for advanced club or experts players who know most assessments 
of the above listed endgames but are not able to play them perfectly (or at least well) with the clock 
ticking and decide to study what they´ve already noticed and imperfectly practiced for a long time 
(compare the downloadable introduction!)

Any reviews of this book, yet ?
