Idea: to not reveal solution after submit, encouraging users to think a bit longer

[gyermolenko]

E.g. for
task "Find the squares that are attacked by all pieces."
Position: Bc1 Rg6

Submitting "g5" immediately leads to red "Wrong solution!" message. (because of missed "h6")

But the best (imho) would be to not stop the task and ask for more inputs. Like "Your are missing possible solution" or "There are other variants" or "Think more" and explicit "Reveal solution" / "I give up" btn.

Like with many multiple-choice tests and exercises sometimes it makes sense to encourage users. Maybe even give "partial points" for a partial solution.

That's a good idea. To show gradually the responses.
