Nice Anti batteries! What is Zabunov effect ?

• Luis Miguel says:

Hi, Seetharaman,
In the final mate positions, neutral contra rookhopper acts as front piece in a phase and as rear piece in the other phase. With this two roles, I think neutral contra rookhopper shows Zabunov effect. The same exchange of roles happens for the other 3 themathic pieces.

But really, I’m not sure of the strict requirements in Zabunov theme:
¿it requires always 3 different pieces A (rear and front) B (rear) and C (front) instead two pieces exchanging roles?
¿it requires only batterie play instead anti-batterie play?
¿it requires rear and front roles in the same phase or also applies throughout all phases?
