Mirror, mirror, on the wall....

This thread is for all mirror mate puzzles.

Mirror mate is where a mate occurs with eight adjoining squares of a king is unoccupied (from The Oxford Companion to Chess).

Here is a continuation of Browne-Quinterors at Wijk aan Zee in 1974. Sicilian Defence, Moscow Variation.

I wonder what are fewest pieces or most adjoining spaces allowed with mate!

This is the only one I could think of with most adjoining spaces surrounding King for a mate. Question is what is the fewest pieces possible for most adjacent squares vacant with mate?

Well it's not really a mirror mate Ronald, as the adjoining 8 squares around the King are not empty!

It's not clear what you mean by 'most adjoining spaces'. Is it something like 'largest rectanglur area of squares with only a bK in it'?

Yup! Per definition of Oxford Companion that is it! I believe it has something to do with squares forming an "invisible wall of mirrors" around the king to completely immobilize him.

That would be simple to answer: 7x8 with 5 units.
