Pretty endgame!
1.Kd6 f5 2.Rg8+ +-
Or 1.Kd6 Rd8+ 2.Kc7 Rc7+ 3.Kc6 +/-
Nice! Here's it in puzzle format:
kd6
The real part of the puzzle starts at that point.
I can say that it is very difficult puzzle.
It's so long.
Can you calculate so many black and white moves in a real game?
Calculate in your mind?
This is why I don't like puzzles of that kind.
It's an endgame study and studies are hard. Many things of value in life require hard work. The reward is an aesthetic experience and pride of achievement. But if you prefer binge watching The Crown who am I to claim your are wrong?
