::: comment :::

The only thing I know for that puzle is that is has at least one 11.x rating.

As often, the start using the generation of puzzles having a symmetry of given has been very efficient.

It could be (I'll check to morrow) that I got the puzzle(s) included in the data base of potential hardest at the first shot (half an hour).

Alternative strategies seem to have difficulty to produce all good high ratings I got working with a very limited power
