Key moves

These moves tell the MoveTrainer® to teach you a variation/line from a specific point only.

Each variation in an opening course can have up to two 'Key Moves.' By marking a move as key, the course creator enables students to start studying from that key move and continue through to the next one

So for instance, if the whole course is based around 1. e4 e5 2. Bc4, the key moves option will enable you to skip the first two moves and study only after them.
