When a Ferz-King Leaves behind Ferz-King-Sentinelles

Ser-h=3

Black Ferz-King-Sentinelles-Maker Ferz-King* (FzS) in e2

No White King

1. FzSe2xd3 [bFzSe2] 2. Fzsd3-e4 [bFzSd3] 3. FzSe4-f3 [bFzSe4] = ***

* The Ferz moves and takes one square diagonally. The Ferz-King is a King that moves like a Ferz. A Ferz-King-Sentinelles-Maker Ferz-King is a Ferz-King that, on moving, leaves behind a Ferz-King.

** Of course, I could not verify my solution.
