The once guarded bishop at f8 is fatal for black (not to mention the rook’s pawn on the second rank!):
1. Bb5! ab5
Any other move leads to 2.Rf8#. Continuing:
2. Qb5 Rc6 (Kd8 3.Rf8#; Rd7 3.Qd7#)
3. Qc6 Kd8
4. Qd7#
1. Bb5+ axb5
2. Qxb5+ Rd7
3. Qxd7++
If
2. … Kd8
3. Rxf8++
If
1. … Rd7
2. Bxd7+ Kd8
3. Rxf8++
Interesting.
Wasted some time considering 1. Rxf8+ Kxf8 2. Qxd6+ Ne7 3. Qd8+ Kf7 4. Qxh8 but could not find a way out for white after 4. … Qg1+ followed by 5. … h1(Q).

After looking at 1. Rxf8+ Kxf8 2. Qxd6+, which loses to 2. … Ne7,
I spotted:
1. Bb5+ axb5 [1. … Kd8 2. Qc7#] [1. … Rd7 2. Rxf8#]
2. Qxb5+ Kd8 [2. … Rd7 3. Qxd7#]
3. Rxf8#]
qc8+han
Rxf8+
In my previous post, I left out one Black defense after
1. Bb5+ axb5 2. Qxb5+, which was
2… Rc6
3. Qxc6+ Kd8
4. Rxf8#
Bb5+
1. Qb5+… Pxb5 2. Bxb5+ Rc6 3. Bxc6+ Kd8 4. Rxf8#
Bb5+
At first I was distracted by 1. Rxf8+? but then I found:
1. Bb5+ axb5 (1. – Kd8 2. Rxf8#; 1. – Rd7 2. Bxd7+ Kd8 3. Rxf8#)
2. Qxb5+ Rd7 (2. – Kd8 3. Rxf8#)
3. Qxd7#
Bb5+++

Gracious solution.
The instinct of a chess player first focuses versus the columns opened.
Instead …
1. Bb5+ axb5
2. Qxb5+ Kd8
3. Rxf8#
I was curious to know if anyone still uses the “Kotov system” to solve the forced position.
I use it since I was young.
