  Well done, King!
  “Greetings,

  1. Ra8+! Kb7!?

  (1…Kxa8 2.b7+! Kxb7 3. Qa7+ Kc6 4. Rc3+ Kd5 5. Qd4+ Ke6 6. Rc6+ Kf7 7. Qf6+ Ke8 8. Rc8+ with mate to follow shortly.)”

  Yes, I found the same line, with mate next move.

  “2. Ra7+…”

  Here I instead found
  2 Nd6+!

  In fact, were black not threatening mate with …Bh2+, KxB Qxg2++, Nd6 would have been my main candidate move, as it blocks the d7 rook from mating as well as covers the b7 square, boxing in the black king. Your variation works and leads to mate just as well. The one I found continues:

  2 (Nd6+) RxN
  3 Ra7+ Kb8
  4 Qc7++

  or
  2 (Nd6+) KxR
  3 Qd5+! Kb8
  4 QxR+ Qe8
  5 QxQ++

  I first looked at 1 Nd6, but then seeing that white gets mated, figured that it would be handy later if the king ever gets driven to b7, as well as blocking the rook from d5, which could fork the king and g1 rook if the queen could get there.

  The first move Ra8+ was easy to find because white needs to play all checks due to being on the brink of mate, and all three queen checks didn’t do anything, so it had to be Ra8+, and there were nice tactics whether black takes or runs.
