delightfulagony: Only A5 stops the attacker from making a dead shape, other ones allow the attacker to make a bulky five which will end with the death of the defender. After A5 the attacker needs to play C4, if they tenuki the defender will kill and live. Maybe it is worth it to include C4 in the sgf? Provided it is correct of course I could be mistaken.
[current position] + C16
caranthir: Thanks for your comment. You are of course correct that C16 makes seki, but it's so small that it would be unrealistic in a real game until very small endgame; therefore i'd rather not include it.
Gatico54: For me they are all seki, I don't understand how A5 allows to kil.
caranthir: [TwT: Player A5 is seki. If tenuki and attacker plays there it is dead: bulky five.] A small correction: Rabbity six / flower six / hanaroku / whatever you prefer to call it, not bulky five. ------- Player A5 is not yet seki, enemy would have to work for it by investing a whole move in gote (and same goes for us to make it alive with points). So it's unsettled, maybe alive with points, maybe seki.
