Thanks to gdc for version of the app which understands the anti-giraffe rule!
N.B. "Giraffe" is the name given in fairy chess problems to the (1,4)‑counterpart to the knight, as can be seen in the bonus chess problem with both knights replaced by Giraffes. (e.g. white Giraffe could play from e8 to f4).
Helpmate in 3 (Black helps White to give mate after BW BW BW)
Knights replaced by Giraffes.

Fantastic follow-up to the original giraffe hunt. Silky smooth finish and nice presentation of "the idea".
