guile: Hey Masters ! This is so uncool to taunt us like that :p . I'll add this essential moves on the SGF (bad bad bad masters) before coming back breaking some rocks on the back of the penitentiary 's yard.
Met: I think I was in a new variation and then the position linked to some wrong node. So to reiterate: This black B1 [current position] is a wrong move marked correct. W should now respond B2 and get a ko.
Met: [current position]
W D1 is a wrong move in this refutation as B A1 kills it. Should have been W A1 instead.
kovarex: I don't see any error in this.
WT19 doesn't kill. THe T19 kills, but with bent four in the corner, which is a lower tier kill compared to normal unconditional kill.
or B12 or A13 :-)
