1. … Ke6 — the “low resistance” line.
2. Qe8+ Kd6
3. Rxd7+ Kc6
4. Qc8+ Qc7
5. Qxc7#

3. … Kc7
4. Qa7+ Kd6
if (4. … Kc6, 5 Qxd7#)
5. Qxd7+ Ke5
6. Qxd5#
I’m seeing 4 or 5 different lines that all end in 6-move mate. Regardless, they all start out with Rc7+.
Thank Susan! 😀
let me try GM Polgar…
…..1Rc2+
after Ke3 2.Qg1..Kf3…3Qh1..Ke3…4Qe4.
Kf2..5Qe2+…ang Qg2mate..

1. Rc2 Ke3
2. Qg1 Kf3 (Kd3 Qd1)
3. Qh1 Kf2 (Ke3 Qe4)
4. Qh2 Kf1
5. Qe2 Kg1

I think using White-to-move problems is more convenient so we don’t have to deal with a flip view of the board when giving a solution.
If you don’t want to be confused about the flipped board, be my guest Black to move and checkmate in 6
Using the board there you won’t be getting Rf7 instead of Rc2 or the correct Rc2 but played by white (as in Anon@2:34). Yes, I did find the solution myself (which proves it isn’t that tough) but then I verify the lines with a chess engine (to avoid wasting time posting it).
