One exception to the rule is longer problems - some of those start with checks. Here is an example.

White to play and mate in 12
Starts with 1.Bc6+, but this is not considered a flaw.
I think I have the idea let me just work out the kinks.

I'm completely stumped. Can I have a clue?

does the checkmate finish on the a-file or in the middle of the board? Would be nice to have a vague idea of where I'm pushing this king around to...

you have to look for a pattern clear a bunch of squares or use triangulation. thats the best hint I can give without giving ideas away

You need to make the HIDDEN words not capitals 😉

Consider me officially beaten. I've given about 2 hours a day since you posted that 12 move puzzle, and I cannot stop the opening of a flight square on b3, and/or a pinning/check with Ra7. If noone gets it, please give us the solution at some distant point in the future
