Interesting! A very different solve than what is typically expected with this puzzle. I will have to do some study to see if I can find a suitable rebuttle. Very good work Mr. Morgski!
ADD: Ok! After some more study on this I can see you are definitely correct! If black tries to get the rook behind his pawn, he is certainly doomed. However knowing black is doomed by trying to push the pawn in this way...why shouldn't black instead hang the pawn to try and get an attack on one of the bishops?
1 Rd8 a2!

This is Philidor's position. I think white can force this position or one similar(Lolli position) even without the cooperative checks from black.
hm. Perhaps...I think black can muster a draw here though tomtom... however white may be able to keep both bishops! What if 4. Bb3 probably 4...Rb4 (4 ... Ra3 5 Rd4+ and 6 Rb4 wins) 5. Rd4+

Q
5...Rxd4 6.Kxd4 Kxh4 right?
Edit: The position shown is a win for white... If it is a draw then it is before this posiiton.
I am not sure how white forces this but with the king on the edge of the board I think white may be able to force this position(or rotation) or a similar position like the lolli(or rotation).

Q
5...Rg4 refutes this idea so the other solution is definitely the only one.

how can 5...Rg4 if the black rook is on b4 and a white rook is on d4? I'm sure there is a misunderstanding somewhere... This solution is a "domination" of the black rook.

I meant to reply and quote my previous "solution" that ended with a philidor position.

My mistake.
Ah! That makes much more sense! Thanks for clarifying. Another one of my favorites is by Punchinello and is a bit trickier than would usually be believed from such a straight forward looking ending.
