Unfortunatelly, dual avoidance (Kc4?) is lost in this the most economical version.
You are right Rodolfo! This is my sin
In my opinion the anti-logical tries (Kc4/Kd4) are not worthy of highlighting.
True, there is something anti-logical in those tries. Still, I think they worth to be indicated since they both fail by the same specific reason - line-closure of friendly linear officer.

I like this version more than others

Solution remains unchanged but here WR delivers mate with the support of WSf6
The best ecomomy on this moment.
Who can suggest a Meredith position?!
8/4k3/4NN2/2P5/1P6/rbbK1p2/B1QR4/B7
I know about this opportunity - Nebojsa Joksimovis has sent me this position on 26 April via email but I have reject it because the try Ke4? (false move along thematic line) hasn't its identical orthogonal try Kd4??
Okay sir. Thank you for the explanation. Maybe a black knight at g3 may preserve these effects instead of rook at e1. If my understanding is correct, hope this should be fine.
B7/B1QR4/rbbK2n1/8/p1p5/4NN2/2P1k3/8
B3r3/B1QR4/rbbK4/8/p1p5/4NN2/2P1k3/8
Yes, it is pretty good.
I still prefer version by Nebojsa Joksimovich (#12) since it has no additional (accidental) effects/features such as supporting of mating piece
1.Bxc7+ Kxc7(Kc5?) 2.Bb5 Rd2#
1.Bxd7 Kxd7(Kd5?) 2.Ba5 Qh2#
Wow, such a huge number of versions!
We are going to blow up the judge's mind
