These variations get you ready to play an opening variation or even an entire repertoire with as little study time as possible.

Staff members run the moves of a repertoire through a database, after which we rank the lines according to popularity and pick the top 10%. The author/s and staff may also trim the length of the variations and add visual aids, making the lines easier to learn.

The result is a chapter that gives you a thorough overview of the repertoire's most important variations and their standard plans and ideas.
