After Bxb7, there is no rook to move to Rg8

Because your rook has been voluntary offered.

Hello everyone, Asorski at your service!

The right move is:

1. Ke2!! 

And now: 1...Bb7/Bxf5 2. Rg8+ Bc8 3. Rxc8#,

              1...Be6 2. Nb8+ Bd5  3. Bxd5#

              1...Bd7 2. Nb8+ Bc6 (2...Kxa7  3. Qg1#) 3. Bxc6#

1...Ba6+  2.Nab5!! 

And now: 2... Bxb5+ 3. axb5#

              2... Bc8  3. Ra7#

2... Bb7  3.Nc7#!

The amazing contruction of this problem makes a solver think that this is very easy to solve but it's the other way around!

The hidden resources at black's disposal is noted here. The 1...Bd7! followed by 2...Kb7!! move prevents any attempt by white to mate in 3. Also, the 1...Be6 move defends g8 and threatens 2..Bd5+.

Lastly, the problemist uses more than 16 white pieces to show his idea, but a King's move does it! This makes the puzzle computer-proof, free from cheaters.

My hat's off to the composer of this amazing problem!

This is one of the most 'difficult and easiest' 3-movers I've seen in years!

After Rg8+, the king prefers Kb7 and be saved.
