To built a mate position, the white first do an anticipatory interference of bishop. Two model mates (author)

Dear Vidadi!
The bRb4 not justified, enough bSb4 too...
Best regards:

You are right Gabor Tar! Composer obviously did not test this possibility!. Thanks for the observation!

Adding tempo move to the first solution also is nice, but at the price of a heavy position. Let us see what the composer thinks.

I think a better position with a heavy uniform game than an easy position with discord in the game whites. All best, Kenan

In Kenan's example, 2....Kb7 is not an interesting and not a "natural" tempo move. The mechanism is not uniform. It could be made better, with more dynamics, or even with additional black tempo move in one solution.
But destroying the good mechanism to "create" a bad tempo move is not desirable.

The original author's scheme for the idea is good and it could be realized with the optimal mechanism and ideal mates in a miniature. Obviously, wSc6 could guard b4,d4,e5; only some adjustments and rotations are needed.

And what good is the author's version? In the first phase of an elephant makes a move expectations in the second, the king goes to grab and eat this inconsistency. In my version Kb7 whites only move expectations, other moves to destroy the matte painting. So white makes a move to get the tempo to the king went into the matte box. So that the second white moves are similar.

How about this version?
Position:
W:Kb6 Lb1 Se1 bb4 be4
B:Ke3 Se5 bb2 bb3 bc4 bd4
H#3, 2 sols.
1.Kf4 Sd3+ 2.Kxe4 Kc7 3.Kd5 Sf4#
1.c3 Sc2+ 2.Kd3 Ka5 3.Kc4 Sa3#

It is an improvement Kennth Solja, but the play is not still fully matching. Just shows how much possibilities are there in this scheme.

How about the following?
