Zeldy: Thanks for the answer to the suggestion.
I think it has value because the situation O2O1 seems to be more possible to happen in a beginner/intermed game than the actual answer, and the only possible solution is
O2O1N2N1M2M1L1L2P1M1. To be more precise in the answer, a stone in J1 in the problem would be perfect.
An antecipated move leads to the death of the group, as I showed in the wrong variants. That's it. Sorry for the flood in comments! This website is amazing
posetcay: It becomes a completely different problem then, which is already covered in later collections.
Zeldy: I think this problem should have an variation: O2O1N1 as a wrong alternative. It may seem like an easy solution, but can trick the player to lose the eye
