Fupfv:
2John: You are right.

John:
@Fupvf: the problem is to kill, not to live. H18 G18 C19 variation is death, while H18 E19 is alive. Hence G18 response is wrong.

Fupfv:
2John: H18 G18 - group is alive and with more points that in H18 E19 variant.

John:
(UL corner) Variation starting with H18 G18 should not exist - the second move should always be E19. The latter gives live, while G18 mistakenly allows the group to be killed.

pappas:
last move: the other atari works (r1) - is it cuz it leaves a ko threat that it is deemed wrong? i think it should be marked correct
