A quick note on case 3 on importing a 2009 book bought as an EBook at EverymanChess.com

I imported the CBV file into ChessBase reader. It seems to be a complete import. It seems that I can add moves and variations, BUT they are not saved!

Case 1, original BookUP side by side with COW. Success. I went to http://www.columbia.edu/~em36/macos9win.html and downloaded a Mac OS9 emulator for Windows. I now run my original BookUp files side-by-side with the modern COW. I can see my thoughts, comments, and original analysis from years past an...

I used COW Professional to do two different databases searches. In each case, COW Pro came back with 1,000 games. In at least one case, I had reason to think that more games were available. Does COW Pro's search engine have a 1,000 game limit?

I'm in the process of converting a large COW Express file (2018 games) to COW Pro. It takes a long time and my computer gets hot. I ran into some luck as my computer eventually goes to sleep and cools off. When I wake my computer, new positions are loaded until the next break. I'm glad the conversio...

This is not really a COW topic, but is COW related. I use COW extensively, but I find that it is complemented with a game database. Back in the BookUp days, I used Exachess. One feature it provided was game statistics from the current chess position. I would copy those statistics from Exachess and p...

I recently gave the same task to COW Express and COW Professional, but my experiences differed. COW Express has been around awhile, is well polished, and has no rough edges that I have seen. COW Express: I selected my 2018 game file, then requested a search. For my ECO code, I typed c15. This was co...

I just ran across an article on "contempt" in this context. It's a way to maintain more play in the position:

Can you send me a PGN file that you're having trouble with?

When I drag the Fischer file to this box (to add as an enclosure), I get the error: "Invalid file extension: Fischer.pgn"

I was analyzing in COW Professional, build 92, with the latest version of SF. In particular, I was looking at the MacCutcheon French with 5Ne2. It may not be the best move, but looks to provide more fluid play than other moves. I followed SF's suggestions for a few moves. When it is white to move, i...

Yes, build 92 solved my problem. I can now click on any candidate move on the list and it plays directly.

"You might consider using the regular bookmark to keep track of play to a certain position." You lost me there. I can't find a bookmark command in COW.
