Using COW Pro, I regularly reduce the size of the window. Saving screen space allows me to open two windows at once, side by side. I reduce the width until I can just see the candidate pop-up button (downward facing triangle). Doing so cuts off some of the header: Opening name, certainty, Move field...

I have several COW professional databases and am getting more by converting by COW express files. I have three basic questions about the Professional version 1. Opposite (right of) the candidate moves, I see a bar with three segments, white, gray, black. I assumed this corresponded to win loss resul...

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"
