Creation of white anti-batteries K/NAO after bypass maneuvers of the white NAOs. Interchange of functions between both NAOs – one of them creates anti-battery, another one is included by the bS to guard fields around the black King. [Model mates]* in Meredith-form.

* Originally I’ve written Model Mates, however it is not right for the 1st solution – see a comment by Harry Fougiaxis (below). The problem is C+ with model mates in case of change wpf2→bpg3.

The mate in the first solution (ending to Kg6#) is not a model, as the e3 square is guarded twice. A possibility would be to remove the white pf2 and add a black pg3.
