rxf4 is mate in one
After 1. Rxf4+. 1...Qxg8 (So not a mate in one.) 2.Nb4+ Kxa3. Not a mate in two.
Either 1. Nc8# , but as you're supposed to do it in 2 moves, 1. Ra4+ b3, 2. Qxb3#
1. Nc8# is impossible. I assume you meant 1. Nc1+. But then 1...dxc1=Q 2. Rxc1. Not a mate in two.
And after 1. Ra4+, 1...Qxg8. No mate in two anywhere.
Nobody's guess was close . . . except einstein_69101's. Great find, man.
Brilliant puzzle!
