19188 (Zlatko Mihajloski). 1.– Kc5 2.Sc4 (2.Sf3?) Lb5! 3.Dc7+! (Tempoverlust) (3.Dc1?) Kd4 4.Sd2 Ke3 5.Dc1! (5.Sc2?) Kf2 6.Sc2 Le2# – Idealmatt. „Der Umweg der Dame findet hier eine sehr hübsche Miniaturdarstellung.“ (MRit) „Im Mittelpunkt steht das herrliche Idealmatt. Dazu noch: Miniatur, Aristokrat, gute Materialnutzung. Gefällt mir gut.“ (KHS) Der Autor spricht von einem „kontrollierten Tempo, also einem Schachgebot als schwarzem Tempoverlustmanöver, zwecks Zugzwangvermeidung. Bei dem Zug 3.Dc7+! handelt es sich um eine sehr versteckte Hinterstellung. Dazu Idealmatt.“
