      Thematic complex
 
1.Fourfold creation of mixed anti-batteries bK/nDG combined with 4 white Q - sacrifices and black K-cross!
 
2.Line-opening for the black Bc5 that follows to pin of the w.Pf2 and 4 pin-model-mates in ECHO-form!
 
3.TASK: Extremely activity by the white Queen and neutral DG - every thematic piece makes 8 different moves!
 
4.The complex is presented here for the first time.
 
5.Probably we can named such compositions "Neutral - minimal problems" because on the board we have only one neutral figure that directly attacks the black king!
