You don't see it, because 2. d8Q? is the wrong move after 1. ... Rg4. Look again in the post!
Likable in two
Both 3. g4 and 3. Bg4+ mate in time, for instance: 3. Bxg4+ hxg4 4. Rxh8 g3 5. c8Q#. It is not a main line and therefore it is not in the analysis column.
This version might be even better, but more complicated.
Mate in 5 moves.
After 1.Kg1! Rxf7, the solution is the same as above. But how to mate after 1.Kg1 Rg4 ?
Since I liked the depth of the underpromotions, I worked a little longer on these ideas to get a good key move while retaining your powerful try.
To my surprise the new version also delivers a third perfect variation with a queen promotion plus some small stuff. An AUW is not on the card but that would really be too much to ask for.
If you have a good engine please check it. Since mine is buggy I had to cut my analysis into little mosaic pieces and some may still be missing! Edit: Ba6 -> Bb7
(I play the extra queen promotion as the puzzle line)
Wow ! it's a much better version than mine. Congratulations ! I've just checked the varations and it seems correct. Of course the queenside's pawns are a flaw, but a necessary one. It is now a very good problem and the process of composition, starting with a nice but childish mate in two is very interesting.

Thx!
Agreed, the queen side pawn are "heavy" as they say in the game of "Go". In the final analysis they are a consequence of the increased power of Rf7 compared to the previous version. Ne1 performs a similar containment role but that addition pays off really well!
Through the years I found that most compositions are a compromise in the end. There is always something more to wish for. I gladly accept the 90% score on this one.
Btw, with the key move, we've gone full circle! Back to the key of the childish twomover.
@Arisktotle Isn't this a version of this same puzzle, my question who copied who or is it just coincidence?As soon as I seen it I knew what it was.I would have never recognized any of the versions you guys put on here.
By H.R. Agnel. White to mate in two moves.
Well, there are a few similarities - zugzwng and pinmate - but I wouldn't call it "a version" of your first twomover. For one, its the king here that moves into the pin position which makes this key more difficult to foresee. Another difference is how the knight in your first twomover dominates the movements of 2 black rooks which makes for a remarkable display! I like the Agnel-problem better though as it is a miniature (at most 7 units) and the key is better disguised. JoachimJo and I had to work hard to turn the post #1 problem into a worthy composition though our key move is still not as strong as the one in the Agnel-problem (due to the obvious checkmate-threat). But compositions are always a composite of plusses and minuses!
@ Arisktotle I see no solution for 1.Kg1 Rg4 2.d8Q or N Rh8.on post 17 not Rxf7 but rook dominates 8th rank unless Q takes it then its a stalemate if d8 move Ne6 then Rxc8 if bishop move then Rxd8 if you have the complete line to defeat Rh8 please show me
