Farkas: Could you explain please why q1 is labelled as incorrect as first move? This problem seems symmetric, therefore p1 and q1 should be miai. I couldn't find a sequence where q1 as first move was proven as incorrect.
d4rkm4tter: I couldn't find any corner shenanigans either, so lets assume this problem is symmetric.
Splinter: Hi, probelm 26 of the blind spot collection, i think o1-r2-q1 works but it's marked as incorrect. nest would be q2-p2-r1-s2 then the under the stones that the probelm wants us to do, right?
I agree, I can not see a way to avoid ko after starting with O1/R1. Only P1/Q1 are accepted as correct answers now.
