Interesting indeed, I cannot solve it in 5 minutes perhaps due to the board colors and coordinates I am a bit disoriented .

Try this.

CDrill 1200 failed to solve it which is probably right as at that rating level it should not solve such puzzle.

Same position? Anyway I tried it with a few engines ans they all solved it
but for a few the eval was weird.

Are there any interesting themes in this puzzle? The output with Chest was several
hundred lines so hard to tell!

I solved it effortlessly and quickly, so anyone could do that. Hint: Overcome your greed...

Same position?

The first EPD is buggy : one "/" too much and the end and 9 lines in the first diagram.

And therefore a black square at Top left insteed a white square.
