You managed to create a puzzle which leaves the engine puzzled! Its quite simplle to force a draw, but I guess you want to win.
As it seems to come from 960, white can castle long, which must be critical to the solution, but I was unable to find a way. I've to say I didn't looked that long at it, but my first glance showed me that black is running away to safety very fast. Mabe someone will solve it, I won't right now. But thanks for the puzzle, @opperwezen!

@opperwezen Very nice puzzle. I tried solving it (I failed) so I turned on my engine. It said 0.00 for like 5-10 minutes, and after that it found the mate. It's a very nice idea I must say. Also placing it in a 960 position leave the engines struggle. +1 for the puzzle

ow actually the idea of the puzzlewas that Rd4+ draw bxd4 Qd1+
but i was afraid the position maybe is not made for it.
it didnt made it for the variant of 960
i didnt put a engine on it i just had this idea in the morning with Rd4+ idea to get a important check in on d1

I had a dream last night that my left eyebrow disappeared. You're dreaming of positions where engines need a lot to think on the solution.

I saw that drawing line tho. It's quite nice, but I thought your idea was to find the checkmate or something. I was mislead.

Oh boy, I totally missed your post :(
I'll have a look at the puzzle, it looks interesting and not too difficult. But I guess there is more to it :-)

:( missed the stream today. the computers had problems with it it seems. for around 5minutes
