How to handle AUF in Fewest Moves?

[hr.mohr]

At Norrköping Open I got AUF (U2) + A-perm after OLL in my attempt in Fewest Moves. What should I look into in order to be able to cancel that AUF?

You can essentially always beat an A-perm with a commutator insertion, so if it were me, I'd probably not worry about the AUF and just focus on finding an insertion to replace the A-perm. For sure you can find an 8-mover to replace the 9-move A-perm (unless your solution is very short and limited), and odds are you can cancel at least one or two more moves - that should more than make up for anything you'd do to remove the AUF.

I'm always happy when I find an A-perm - it means an easy insertion.

Mads, this is all you need to know.

Keywords being commutators and insertions. My response is thank you

Generally, insertions cancel 2 moves, so instead of having 1+9, it'd probably be 1+6 with an insertion. I've even cancelled 6 moves with an insertion, so they're pretty useful.
