Djab: this sequence works but is claimed "incorrect"
Human : S19 - Computer : T18 -
H : T17 - C : Q17 - H : Q18 - C : P19 - H : S18 - C : N19 - H : R19
there is a bug
Farkas: Please don't send the same message three times. I deleted the other two. Also, I repeat: missing sequence is NOT a bug.
Anyway, your move has been added.
Djab: I have the feeling there is a bug
This pattern is declared « incorrect » but it seems to work :
Black b2. - White a2 - B a3. - W d3. - B d2. - W e1. - B b2
Black can make 2 eyes now.
Am I wrong ?
Farkas: There is no bug here, just a missing sequence. I added sequence.
John: (LL corner) B2 guarantees live with points (right?), while in other ``correct'' variations its seki. Hence only B2 should be correct.
Farkas: Seki is also alive, and is accepted here as correct solution. Furthermore not only B2, but B1 lives without seki, too. Also, I corrected a few moves (but seki is still correct).
If we play Q17 and the opponent answers S18 I don't see any unconditional life?
