when there are two different winning ways chess.com forces u to go with one way. Only problem? U don't know which one that is
in puzzles there is always a better way. sometimes with harder puzzles it's the way that leads to a better position
oh so that's what is it about, when you see a better move that leads to checkmate, and it doesn't work, that means they want you to have a better positioning of the pieces. so they do kinda acknowledge that you could go for checkmate or set a mating net, but straight up telling you, "NO" you will do the puzzel like this, get a better position, oh whats this, you could go for checkmate, but why go for checkmate when you can fork the queen and bishop by checking the king. that actually does make sense to me now.
analyze afterward. if your variation leads to checkmate report it to the moderators and move on. nothing will be done if you create forums not stating the specific puzzle
Progress is not going up all the time, there is ups and downs, that is real progress
