Dont put put solutions for Mate in 2 or 3 problems. It finds all solutions possible and saves more time.

This is from instructions to set a problem:

"It's a good idea to include at least one correct solution in the paths of a mating problem. This lets users see a way to solve it if they're totally perplexed."

I would add that it is also sensible to add multiple variations (= Caissas alternative responses, that lead to different white continuations) to show the full beauty of the problem. Of course you need to run the applet multiple times then. Or navigate the solution.

However, your suggestion has a merit, that it is then impossible to get the problem 'solved' by just animating the (nonexistent) solution.
I have out of the curiousity submitted 3 non-trivial two movers without any solution provided - just to see how they do.

I have to admit, the 1st and 3rd were very hard but I easily solved the second one.

Just put this topic because GOGO and Tomas put no solutions in one of their problems.

Ahh. How the perceptions vary Smile .I rather thought that the second one was more difficult than the others...

The second took me many tries though. I then noticed the bishop sacrifice won with the queen take for an underpromotion to a knight mate.
