🨶h6, 🨼g1: Bishop-Lion
󼎜b5, 󼎝e1: Rose-Lion
: to capture, you must be "observed" by a unit of your side at the beginning of the move
For example 1...b3 does not check the ♔e7 as the 󼎝e1 is not "observed" by a black unit.
🨶h6, "observed" by 🨵h2, have a grip on f4, 🨵e8, "appuyée par le Roi blanc"observed" by white King, control e6 & e5.
♚f5, not "observed", cannot capture g4 or g6.
: unit needing a hurdle to move
: move as a , but with the help of a hurdle on its way

4 - h#2 3 solutions with hunter

Feather, Ch
2015

white Kb1 Pg6b7d6 Bf7 black Sa5a8 Kh8 Pe4 Bf2f5 RRb3
h#2(5+7)
b3: hunter Bishop/Rook
: on b3 is a Bishop-Rook hunter.
He plays like a Bishop in front of him and like a Rook behind him; horizontal moves are forbidden.
It therefore controls squares a2, c2, d1, b4, b5, b6 & b7. This is not a recent idea: Hunters were first introduced in 1943 and generalised in 1950.
