In all solutions there are the same motifs of the first and second black move, but in each solution this motive is different: in 1) line-opening, in 2) unguard of a mating square/line by interference, in 3) sacrifice allowing move of the white knight, in 4) direct unguard of a mating square. 2+2 play of the white bishop and knight (authors)
Во всех решениях одинаковые мотивы B1 и B2, но в каждом отдельном решении они разные: в 1) открытие линии, в 2) снятие контроля над матовым полем/линией посредством перекрытия, в 3) деблокирующая жертва, в 4) прямое снятие контроля над матовым полем. Двойная игра белого слона и коня в парах решений (авторы)

I could not find any other examples (with given material -
editorial ) of this use of a critical move allowing the white king to block the bishop's power and allow the black king access to d2. The position is very delicate and the solver might search first for the mate with the BK on a1 and a promoted bishop but that fails by half a move. The kings travel first in opposite directions but then "meet up" at the end (author)

Both Kings remain stationary in 'a' but do a bit of a walk in 'b'; long sweep of the promoted queen in 'a' for the model mate with a short step in 'b' for a model mate; two different black promotions, one for clearance and the other for sacrifice. Both show dual avoidance; in 'a' only 6. Se1 doesn't disturb and in 'b' the initial promotion 1. d1=Q? would mate white! (author)

The white Indian portion of this problem has been shown often; in the second solution Black adds his own critical move that blocks the action of the queen to allow the White king to take a square and allow the bishop mate. I mention the third possible solution with the "striptease" of the knight primarily because it is possible and it would be best not to shoehorn it into another problem. However it lacks thematic connection to the first two solutions that rely on critical moves except in that the white bishop blocks out the action of the queen (author)

The problem was rewarded with 8th HM in 8th FIDE World Cup (07/2020) in the preliminary award but later the tourney judge has desided to remove the problem from the award due to presence of
P1005220 . In my opinion, the forerunner is partial, so I has desided to publish Gavryliv's work (director)

Парадокс Зилахи: кроме двух фаз с темой Зилахи,имеется как минимум 3-я фаза, где белые фигуры не берутся, а ставят мат с участием этих фигур.Парадокс особенно проявляется в трёх и многоходовой форме. Предложил в 2013 году Алексей Ивунин (авторы)
2 пары решений: в первой - активный Зилахи, во второй - маты разными фигурами с одного поля. Compare to | сравните с:

Над белыми висит угроза мата, поэтому им надо поспешить. Черным же, наоборот, нужно промедлить. Комбинация быстрого белого и медленного черного эксцельсиоров с превращением пешек в однотипные фигуры. Батарейный темпошах, многочисленные "топологические" эффекты, построение белой королевской батареи, батарейный мат, минимальная задача.
