The training wizard is Chess Openings Wizard’s way of testing your memory of the lines in the ebook.
No matter how many times you go over variations, you can never be certain that you’ve memorized them. The training wizard tests you by playing mock games against you to see how may you have committed to memory.
The training wizard can also show you how many positions you’ve memorized out of the entire ebook. This is especially handy when you’ve purchased an opening repertoire that you want to learn.
