Solution -- Shlomo Seider

Credit: see yesterday's post, "Shlomo Seider"

The detailed solution to the three-mover from yesterday, from the same source as the problem itself, i.e, the article about Seider in Shachmat Be'Yisrael 

There is a possibility for a Novotny theme on c5, which suggests itself upon a cursory examination of the position. But immediate attempts fail:

1. Ndc5+? RxN
1. Nec5+? BxN
[While, in this position, 1. Rc5 threatens nothing -- A. P.]

The Key is 1. Be1!, adding protection to b4 and threatening 2. Bb3+ BxB 3. axB#

All defenses allow the Novotny theme on c5:

1. ... e6 (clears the 7th rank) 2. Ndc5+!
2. ... Bxc5 3. Nc3#
2. ... Rxc5 3. Qa7#

1. ... d2 (clears the b1-h7 diagonal) 2. Nec5+!
2. ... Bxc5 Qxc2#
2. ... Rxc5 Nb6#

And finally,

1. ... Rxg8 (gives up the possibility of Rxh7) 2. Rc5!
2. ... Bxc5 3. Nc3#
2. ... Rxc5 3. Nb6#
