As I’ve been trying more and more, I have to give my compliments to the site creator.
This is not another “puzzle” collection, but a series of “real world” situation where you have to find a good move, like in real games.
Only a small suggestion. In problems where the computer sacrifices a piece just before conceding the win (ie, there is only one legal move for the human before “congrats”) it would make sense to stop at the move before.
