Daviid:
There is a 'correct' answer with the excnhage of A13 A16 early in the fight. I think this is wrong. because that is the ko threat needed to save the group.

posetcay:
There are enough local ko threats and asking it early makes the ko heavier for the opponent, so it is ok. Opponent won't realistically play that ko anyway, it is too heavy, he will just let black capture the three stones and live in gote.
