White wins

Hi, this a puzzle I composed some years ago but I have never published it.

Can someone give it a try?

What is white's assignment? Win? Draw? I currently can't see him achieve either though I may be overlooking a trick.

White to move and win?

Here is the solution.

Let me know if you find something wrong with it.

1.h7+ Kh8 (1...Kg7 2.Rxc7) 2.Ra5 Qxa5 (2...Qg2+ 3.Kf6 b6 [3...b5 4.Rxb5 Qa8 5.g7+ kxh7 6.Rh5+ Kg8 7.Rh8++] 4.Rg5 Qxg5 5.fxg5) 3.Kh6 Qh5+ 4.Kxh5 c2 (4...Kg7 5.f5 c2 6.f6) 5.Kh6 c1=Q 6.h7++

Excellent study! I can find nothing wrong with it though I only 'hand-checked'. An obvious frailty is that the rook on c5 is 'en-prise'. It may be possible to find an intro to 'explain' that position. But anyway, the move 2. Ra5!! is an amazing find! All the pawns are in the right position to keep the bQ at bay.

2.Ra5 uses the same motif as Mitrofanov's unguarded guard in his Millenium study.

Stockfish says that 4... c2 is a blunder, and black should instead play Kg7. But that would only prolong the mate, because 5.f5 c2 6.f6+ Kxf6 7.h8=Q+. and then you can even promote to a second queen.

Don't believe everything Stupidfish tells you Wink

DO NOT use an engine for endgame study.  Also...DO NOT blindly trust everything they tell you.

Just checked. And why do y'all keep saying that i'm believing it? I even said in my comment that it would just prolong the mate and it's a dumb conclusion.
