Dacha Tactics #43 - "sleeping knight" gets a good night's sleep in the dark.

This is from a game of mine. After an exciting Budapest gambit skirmish, a strange position has arisen. His king isn't great but our powerful "sleeping" knight is getting booted. Or is it? Neither side has dark bishops so dark will always be an important and sought-after color. Sometimes this is through mini bishops, sometimes it's a queen on dark, and sometimes it's other ways. Let's dig deep for dark harmony!
