StephaneLamy: I guess it depends on the rules: chinese rules where white has to play last (the rule I'm used to on GoQuest), or japanese rule where we just fill up the dame and black can do the last move (probably the rule you have in mind).

Sadaharu: All these problems are based on Japanese rules. Chinese rules don't work because the number of stones do not match
StephaneLamy: There are many sequences that end with the same result as the correct one: as a first move for instance B9, C9, H9 or G3 seem to be all equivalent.
