One can buy integrated chess books/databases for many chess programs. Chessbase, Forward chess, Modern-Chess, and Chessable provide a complete environment for playing through a purchased book with the capability of personal or engine analysis of "what if" lines.

I also use Chess Opening Wizard (COW), not so much for purchased books (where it greatly lags the competition) as for a book/data base that I have concocted and which resides on my computer. This is just my choice, and not a recommendation.

Given my choice of COW, the next topic is integration. I previously developed a COW file on D38-D39. I have Krishnater's Chessable course on the Manhattan. One cannot simply do a mass download/import or mass copy and paste. However, a slower but still efective way works.

I open the Chessable product in Windows and give it 60% of the screen. I resize my COW file in the remaining space. I don't think it is too cumbersome to play the moves in both environments. Also, I can copy a comment from Chessable and paste it into COW. I do so with attribution.

Every program match-up is different. I decided to mention this Chessable-COW match because I worked on it this morning and it's fresh on my mind.

Fans of other chess tools can argue that COW use is optional. Probably true, but I find it a useful tool for integrating several products (to include ChessPublishing dowloads!).

Build 93; Windows - thanks for that link; he said he would perhaps return to this issue after the mobile versions came out; if I'm not wrong those did come out recently, so maybe now it'll be addressed? 

Hi, does anyone know if there is a way to export all of the lines I have entered into COW as one big PGN? PGN -> export line as game seems to only export one line, the one I'm currently viewing, as opposed to the whole repertoire.

Thanks.
