The solutions are not quite matchec: 1.Rc5 is an anticipatory selfpin, while 1.Ree3 is a simple block - in both cases, also with anticipatory line-opening for White, which dictates Black's choice of first move.

I would not use the term "dual avoidance" for this choice of moves, for the right choice doesn't depend on an extra effect produced by the play - it is simply that B1 must do TWO things, doing only one of them is not sufficient.

I have economisized the problem a bit, in this version is only 15 pieces (5+10)

W: Kc8, Dc1, Ta4, La3, bf6 = 5.
B: Ke5, Tb1, Te2, Sg8, ba6,bc2,bd5,bf5,bg5 = 10.
H#2, 2 solutions

1. Sc5 Db2+ 2. Kd6 Ta6#
1. Te3 Dd1+ 2. Kf4 Ld6#
Pinmates, no dual avoidance, like Kjell says, and I agree.
Away is black Q and two pawns and also one white pawn.

Спасибо за ваш труд коллеги, Если без анти-дуалев, Тогда так самый лучший вариант.Три мата с активными сама связками черных фигур.
