It’s a winning position for white. I need to go to bed now. I will solve your puzzle tomorrow.
Well done. The puzzle is a bit marred by that long sideline, but the win is clear.
And if you solve the first one quickly, here is another spectacular puzzle that you will either solve quickly, or take a very long time. The first time I saw it, it took me hours to find the right beginning, but once I saw it, I couldn’t believe I didn’t see it earlier.
8/1q1p4/4p1p1/2R3P1/k6P/8/8/K2R4 w
It took me 20 minutes to solve it.

Alena,
I could never determine clearly if 1.Rc4 wins for white- it might, but it might not. You would really need to use a high powered chess engine that could calculate out the lines to a depth of at least 25-30 moves.
However, there is a move at white’s very first move that leaves no doubt about the matter- it wins in all variations and can be shown as winning with about a minute’s worth of work in the head. So you need to find that.
I’m in doubt between Rb1 and h5.
Think about what you could do if you could limit the black queen’s mobility with white’s very first move.
It took me several hours to solve it 🙂 but all lines are victorious.
1. Rdd5 exd5
2. Rc2 d4
3. Ra2+ Kb5
4. Rb2+ Kc6
5. Rxb7 Kxb7
6. h5 d3
7. Kb2 gxh5
8. g6 d2
9. Kc2 d1=Q+
10. Kxd1 Kc7
11. g7 Kd6
12. g8=Q
Like you, the first time I saw this puzzle, I spent hours looking and trying to prove all variations of 1.Rc4, 1.Rb1 won, but the variations were too numerous to be certain. I do think it likely 1.Rc4 eventually wins, but 1.R1d5 is 100% won without much thought needed.
And once you find the much simpler winning line in this puzzle, there are two more puzzles in the next thread.
Rf8+ Bxf8
Rxf8+Qxf8
Qxg6+Qg7Nf6+
Kf8 Qe8#
