It is must have for chess enthusiasts and learners. It has got features like opening repertoire managment, backsolving(once u feed it one of your games, the program determines where u could have chosen a better line of play. Anyways if u still havent got it, I have included flash tutorials on what it is, and also explaining other features.)
I have included a host of e-books( no, they are not the normal electronic books. Somehow, the programmer for bookup chose to call bookup files "e-books") containing grandmaster's repertoires, tactics and endgame training, and also on other openings.
Using this software u can also test your opening theory. It has a good training feature. Some of u who play chess on the internet can set bookup to check your games automatically (how to do that? - its included as a flash video) and find yours' or your opponent novelties preparing u better.
Apart from included e-books, u can create your own opening repertoires, add your novelties and have an engine check whether its good or bad (included engine is crafty. The Bookup program that i am uploading here is not the latest version. The latest version has support for UCI engines also. Unfortunately i haven,t been able to find version upgrades anywhere in p2p network - including emule. Of course u can buy the upgrades from www.bookup.com! If any one can find them please upload them. The version that i have added has all the features except the UCI engine support).
