A - there is seki, but I can't explain using your method.B - 1 in-space, W has 3 out-space, B 2 out-space, so in-space is W's burden. W can kill, B can make seki.
B has 8 outspaces, W has 7, so B can't be killed.overal spaces - B's 8 and W's 9 (+2 inspace) therefore W can't be killed either.
Excellent!We will meet in-ko, out-ko, big and small-eye-space.I'll post B-S first.And then, I'll post 1-lined CR.
