If there the correct variation is one that avoids ko can you please update the title to mention "no ko?" Without knowing that it feels very harsh to find a correct answer without knowing that it's not the answer Tsumego Hero is looking for.

I would like to apologize for my last message. I wrote in a moment of overwhelming frustration and confusion. Can I request a review that after black/white captures L2 by playing L1 be considered correct? The next move of N2 is incorrect as the counter play of N1, which also capture M1, secures black/white even more.
