Would you trust this man?

Who is this man ?

He wrote a book I'm trying to read.

But I'm finding many errors. (with a little help from Stockfish)

He looks very grim and serious. His clothing-style also suggests some kind of elitism. The overall impression is almost politicianesque.

So no, I don't think I'd trust him unless having spoken to him would reveal that despite his looks he is a nice guy afterall.

He appears to be over thirty.

never trust anyone from Belgium

Is that you OP?

I know, right. They have a thing about pi$$ing in the drinking water.

Black and white photos always look suspect

In series of 13 lessons, grandmaster O'Kelly shows you how you can improve your play to master standard (200 plus on the BCF rating scale, 2200 plus on the FIDE scale)

Well, that didnt really work for me. lol

Put Stockfish away then!

I think over-relying on engines may cloud your own judgment.

Two different styles.

Playing moves that involve a general understanding of the position and lead to positions that can be navigated with logic will get you to 2200.

Alternatively you can have stockfish teach you how to play.  This method involves calculating millions of positions per second and will get you to 3000 level play.

It's not so much that one disproves the other.  Choose the one you think best fits your ability.

The book has a bunch of excercises.

Ver rarely does he include alternate lines in his analysis. So, I'm naturall curious what happens in those lines.

Sometimes, I find it by mself

When I'm unable to do that, I get help from an engine. Mostly, the engine finds good solid lines with the intended result.

But, so far, I must have found half a dozen solutions which don't work, there are responses which busts the premise of the study/puzzle.

Also, the organization of the book is haphazard, the excercises after each chapter has nothing to do with the contents of the chapter.

I have found one or two real gems amongst the excercises, but all in all, I don't think O'Kelly de Galway is one of m favourite authors.

{edit sorryyyyyyyyyyyyyyyyy, the yyyyyyyyyyy on m keboard works only when it wants to

Irishman are, often, inscrutable authors.

Well, I understand, but it's really difficult to find flawless examples in the pre-engine times. You have to accept that those books contain some mistakes (hopefully not too many as O'Kelly was a great analyst and correspondence players.)

As for the exercises, it's true they are completely unrelated to the lessons

Of course I trust him.  I bought a used car from him last week.

He was a GM, more than enough for us mortals. Stockfish is very useful if you can calculate up to 20 moves ahead. 

I dunno. "Kelly's Heroes" is not the same as "O'Kelly's Heroes."
