When preparing an opening repertoine, it is important to note duplicate positions reached through transposition. When such a transposition is noted, if there is more than one continuation, the opening book becomes conflicting and suboptimal. Even if the continuations after the duplicated position match, the opening book is in danger of conflicting with itself.
The added Duplicate Positions finder makes it very easy to see at a glance any such duplicated positions and whether they potentially conflict or not.
Clicking on a move list for a duplicated position opens that position on the main board.
Positions outlined in red have at least two move lists that "continue" from that position.
