Hi Rémi, Yes, you are right. Case11 is not correct. I have fixed it. Case19 is Hanezeki that might never occur in real games. The purpose of this search is to explore some limitations of current MC Go programs so Martin asked me to design the most difficult seki cases on the earth. Then I just did it.
As for komi 7.0, thanks for your suggestion. We will discuss it and announce our decision.
