New Option

Well, I was going through some training, and I have found some better and quicker ways to achieve checkmate. So, I was thinking if we could allow input on the matches, and maybe add multiple ways to achieve checkmate other then what the system is telling us to do. An example would be en.lichess.org/training/32117 where the knight at d4 would move to e2. The bishop at c4 would move to take it, and the rook at d8 would move to d1. Just a thought.

with this movements if Rd1 , Bxd1 then and not is mate bad movement guy

This might have been a bad example, but I like the "Alternate move" functionality at chesstempo.com. Would be nice to have here as well.
