Vincible: I've just checked with KataGo - on empty board this solution is indeed worse by 1.5 points, but as a tsumego problem I don't see why it shouldn't be accepted. It's not inferior solution as you e.g. create worse type of ko, or seki instead of life.
Ivan Detkov: Send the SGF with this variant and we will discuss it.
This is 3 move variant, not sure why you need SGF. Anyway, leave it as it is :)
