The puzzle lidraughts.org/training/325 is part of the puzzle lidraughts.org/training/326

It would be cool if we could report puzzles in general, I've seen some tactics where one of the two winning moves wasn't accepted and all I could do was downvote them.

Yes, maybe a puzzle report option would be a good idea, downvoting will prevent the puzzle from being chosen by the system eventually, but this may require a number of downvotes.

If a puzzle is downright bad or wrong, you can also send one of the mods a message about it, or post it in the forum. We can check on the puzzle and disable it, or remove it from the database.
