It is an Alex Huber FA back from 2001 that was not repeated. I tried it back in 2009 and could the crux moves even as a single move, but then I made the FA of "harder" (longer) exit to the right which was another project by Alex calling it Fugu 9a. Orca still remained mystery for me. In 2017 I finally unlocked a new sequence to the left but could not do it that day. Today I did it in 3 tries. Really hard to grade, but despite it is much shorter than Fugu, I think it is at least equally hard.
