Drazelior: there might be a mistake here, if I did not misread.
I am white and I play to kill black.
I play W G18
B answer is E19
then I play W H17 and it is flagged as an error but I think it kills.
Indeed, if B answers G19, W F18 kills
and there is a miai : if B answers F18, W G19 kills as well.
Am I correct ?
