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:
