How do I move backwards to the prior position on the chessboard?
Sometimes, when I analyse a position I also look for a "back" button, but I don't find it
In those cases, I move backwards manually
So how do I get back to the original chessboard position?
The button "Initial position" retrieves on the chessboard the last position for which a generation process was launched
How do I know which positions tablebases were previously generated for ?
How do I bring up one of those positions on the chessboard?
In fact, when tablebases are generated, millions or billions of positions are generated and stored in the working folder. For now, It is not possible to group them into categories, like "all KNPKBP are in the database".
However, FinalGen could store the initial positions that were generated, so it could list or retrieve them, but this feature has not been implemented. Maybe in a future version.
Regarding the problem you had on your computer, you can re-launch a generation process after a crash, but you should re-generate the tablebases from scratch (not resume the old process, otherwise you can get an "unexpected error"). The data that are already in the tablebases will not be generated again, so you don't need to wait during 11 hours again.
