AWESOME ! My Favorite Chess Tool!

I’ve spent thousands on books, chess engines, lessons & videos and can honestly say that this app is worth 10 times what Dereque is selling it for. Dereque is one of the most thorough, interesting, instructors in the world of chess..PERIOD. The videos are worth the price of the app alone but then you get an incredible opening book that covers the basic lines for all of the most popular chess openings. This is my go to app when I am studying and preparing for tournament play. Awesome job Dereque !

Good info on WHY different openings

He presents good background related to mid game and end game decisions on why certain opening moves are played. This is better than just memorizing setups with no reason. Also he takes the openings a few steps more than others I’ve seen. Watching up to the tenth move or so gives you a better idea what is the idea than just the first 3 or 4 moves. And the practice computer is good to review what he teaches. Nice app.

A "must have" app for chess players

I had seen a few of Dereque's videos on you tube and stumbled across this amazing app. He gives extremely thorough yet concise examinations on all of the great chess openings for white and black. For $2 you simply can't go wrong. I'll be using this app for years as a go-to for reference and expanding my chess repertoire.
