Hello. I only do puzzles right now. I've been stuck on a mate in 3 puzzle for a while, even after I've slept on it: lishogi.org/training/CsmoK

I don't want the answer. But if you see a mate in 3, please say that you do!

I just want to know that there's merit to continuing to spend time on it. Several times over, I've tried everything I see except for not giving a check on the first move, so I'm feeling a bit blind. (I've only been drawing arrows, not moving pieces. Otherwise, I'd already be done.)

Yes, yes there is. If you don't see it, either you haven't tried everything, or you've discarded the correct move without actually seeing that it works.

Yeah, found it pretty quick.
A mild hint below, if you want:

I'd recommend highlighting the king's "safe" squares. How can they be covered?

It's not even mate in 3, it's mate in 5 but the engine replies with an inferior defense that allows you to mate in 3.
