Sorry about the small diagram!

It occurred to me that Build 112, or simply a new COW Express download, might solve all problems.

I tried again. I used the Everyman Chess PGN file for David Vigorito's book Attacking Chess King's Indian Defense vol 1. It imported quickly into COW Express. I played out the start of the Mar Del Plata variation: 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. O-O Nc6 8. d5. Here black must move his queen knight. The COW Express file shows the correct candidate 8...Ne7, plus 4 bogus candidate moves by the king knight! So the pgn is garbled somehow.

I have not had a fault-free import yet from Everyman Chess.

Modern-chess.com (MC) provides PGN files that import perfectly every time. An MC import into COW is a gem - instant productivity. (MC had a 25% off sale over Christmas and I expect one for Easter, as they did that last year.)

"I have not had a fault-free import yet from Everyman Chess."

I have to correct that. My Great Predecessors by Kasparov seems to have read in just fine. I have had trouble with the opening books from Everyman Chess.

Everyman Chess has reduced the price of two of their E-book bundles: Starting Out (3) which is 10 books for $45, and Starting out (4) which is 5 books for $25. At $5 or less a book, I could not refuse. They are older titles, but explanations, rules of thumb, and good games annotated well are timeless.

So I went ahead and got these electronic bundles. They come in CBV and PGN formats only. Kindle and E-Pub formats are not provided. So far, I have uploaded 6 books (PGN files) into COW Pro and I wanted to report on the experience. They upload right away. The ideal is that an entire book be uploaded without mistakes. That goal is mostly met. Some side-variations did not load. Also, there are some errors. For example, Starting Out the Ruy Lopez proceeds with 1e4 e5 2Nf3 Nc6 3Bb5 of course, but also includes 3Nd4 as a candidate move with commentary on the Bird defense (3Bb5 Nd4).

So I got the image to look right! (See Post of Feb 20th, 2020). Looking at the COW image, only the first candidate, 9...Ne7, is valid. The other four are bogus; they each loses a piece! The PGN import is garbled for some reason. It is not just this file. Every opening book (PGN file) that I have from Everyman Chess has this problem.

I will assume that this is an Everyman Chess problem. I have no problem importing a book from Modern Chess (www.modern-chess.com). Their PGN files import flawlessly into Chess Opening Wizard. So you can take this as a plug for Modern Chess.

Books imported from Everyman Chess (EC) are very frustrating to me. About 80% of the book imports without a problem. But the dropped and bogus lines keep cropping up making the import useless. Imports are tantalizingly close - but the cigar keeps exploding in my face. Meanwhile, Everyman Chess CBV files import to another application without fail.

I've tried without success to send a pgn excerpt to Mike and the team. Operator error, no doubt. I do not think it ethical to send an entire book (PGN file). I suggest you buy an opening e-book from Everyman Chess and see the problem for yourself. I think it would be a boon for COW if you could import the EC PGN files without error. Importing their CBV files would be an equivalent solution.

I've tried a lot of software. The optimum, in my opinion, would be to see the book on the left side of the screen (Kindle or ePub format) and a matching COW window on the right side of the screen.

Everyman Chess and Modern Chess are major e-Book publishers. There are others, but I pass them by as their solutions are proprietary and not satisfactory given the high expectations I've acquired as a BookUp user.

A proper import of EC books into COW would make 310 e-books available to users or COW:

As I've mentioned before, some PGN imports work, and some do not. Books, PGN files, from Modern-chess.com import flawlessly. Custom PGN game downloads from Chess Assistant import fine into COW. Chess Informant annotated games, in ChessBase, download fine, then import well into COW.

With only one exception, opening books from Everyman chess do not import satisfactorily.

First the good news. The Queen's Gambit Declined: Vienna from Everyman imports almost perfectly into COW. I can't fault COW here. Some of the book's text comments are found in the introduction to a section. Similar comments are found in the theory section, then again in the annotated games section. So some comments become a little jumbled. Also sometimes they comment about a move before, and sometime after, displaying the move. I open the book as a Kindle book (screen captures essentially) and as a COW eBook, side by side. So it's not too hard to clean up the text. It's kind of a mindless exercise, but it takes a surprising amount of time for an entire book. Still, I learn some of the material along the way. Move imports are perfect.

The bad news comes from all other Everyman opening books. Imports are, maybe, 80-90% right, making them useless. By the way, the books import great into the Everyman game viewer, available on tablets only. So what goes wrong in the COW import of these PGN files? You will have buy some of these books and see for yourself. Until you get this resolved, I can only speculate.

Everyman does something in their books that is a little strange. It has to do with how they introduce, or discuss a position. They provide their comment in the form of a move. It goes something like this:

12-- This is a tricky position.
12Ra3
12Rd3!
12Bg5

On move 12, they have have three candidates. However to COW, it may appear that they have four candidates, the first of which is non-playable. This could mess up PGN import.

This is all very frustrating to me as I would prefer to use COW. As it is, I am becoming more and more proficient using ChessBase as the same books, in CBV format, import flawlessly.

As noted before PGN files from Modern-Chess import flawlessly. I have been harsh as regards Everyman Chess PGN files. That was due to my experience opening older Dangerous Weapons and Starting Out titles. However today I tested several of their Opening Repertoire books and they imported just fine.
