Not only do I make my opening books, I also make data bases for combinations and endgames and transfer from Mac. I keep them small so they only take about ten minutes in training mode. That way I can do them on break. It is a good way to stay sharp when you can’t play games. It is also a good way to keep track of the off beat openings that seem to be played more often to stay out of book. It is also a great way to keep track of your correspondence games.

I’ve had trouble deciding whether this should be rated four or five stars. The case for five stars is that it does exactly what I need it to do and very well. It’s the ideal coach for someone trying to improve at chess. I’ve bought one of the ebooks and been adding variations to it. I like the training that it offers, and I think it’s helpful that it can access a chess engine running on a Mac or PC and show results.The case against five stars is that I’m dissatisfied with the overall look and feel. I’ve written to the developer with feedback and suggestions, and I’m encouraged that he’s not trying to defend how it looks. He agrees with the feedback and asked me to watch for future versions that will become more iPad-like; he was concentrating on functionality for this first version.

I’ve been using Chess Openings Wizard (previously Bookup) since 1991. There really is no other solution for learning your openings. This is my 3rd platform with this app - Windows, Mac, and now iPad.I haven’t experienced any crashes. I was able to copy over my files using dropbox. I also set up remote engine server. No crashes and my repertoire files worked perfect.I did run into a problem where jump to a named position left me unable to get back to the starting position. I added a new named position in my white and black repertoire files called Starting Position to prevent that from happening again.I’d suggest making copies of your files and copying back very carefully. Not a lot of visual cues available that you might be overwriting the wrong direction. I really think I’ll train more with the convenience of the iPad.

I have used it since it first came out decades ago. It was great then and it is even better today!Mike thanks for always working to make it better and better. It is the best way to put your opening repertoires online and play them over and over to get them locked in you memory.Add to that opening hooks you can buy like the London System and you have everything you need to be a better chess player.HIGHLY RECOMMENDED!
