{In infra-functionaries (sometimes strangely called "provocative", which means nothing, while infra-functionary is symmetrical
of ultra-patrol, one wonders moreover why the patrol condition is less restrictive), one can play a unit without condition, it is
only to capture that one must be observed by an enemy unit.}

If one side plays a piece, the opposite side may not play a piece of the same nature in reply.
Attention, it is a Rose on b2, a Vao on e4, a Leo on g3 and
a Lion on h5. In "normal" chess, if one can say with these strange
animals, there would be 4 mates in one move, 1 a8=X, X being one of these 4
fairy pieces. But in "disparate", a single move by the black figure in question
prevents the white figure from capturing the black king.}
