Need Incredibly Hard Puzzle

I need a few that will take me as long as possible; I have a very boring day in school tomorrow with a lot of time to waste. Anything you have that is time consuming will be greatly appreciated.

do some homework/study ;)

Just skip school, and convince some friends to skip with you. And then hang out with them! It's not like one missed day of school will impact your future in any way whatsoever!

Here you go JoelWD  :)  2 puzzles that I made up  :)

Lol, I read mate in 330, but suppose to be mate in 3 (with 30 puzzles named that).

 lol  yeah it is only a mate in 3  :)  It funny how the forum created the address that reads mate in 330.

Try this well-known puzzle called 'Mate The Royal Couple':

FEN: 3qk3/8/8/8/8/8/PPPPPPPP/RNBQKBNR/ w.
mate in n.

puzzle: n=? [the conjecture is n=12]. What is/are the (primary) key(s) i.e. what is/are white's first move(s) that accomplish(es) a mate in {min_n (exists)(mate-in-n)}?

Or try this mate in 12: (there is a unique key)

rnbQKbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBqkBNR/ w

Thanks everybody.
