White wins this very complex and interesting endgame

This is a deep and hard endgame study, composed by Henri Rinck in 1914.
White is on the move and wins this if he plays it right but the lines are long and filled with traps..

That rook sacrifice really stumped me.

[@crypticcrazy3672]

actually got this one. One out of 10 puzzles, I'm on a roll.

[@RamKumar-gy9nb]

You are just brilliant... Thank you very much, God bless you

[@petersiegfriedkrug]

Okay, this position is easy because the black king is on a1. But the rook endings are usually extremely difficult. André Cheron worked intensively on this in his time.

[@tykemorris]

I got the Rh1 move at the start and the Rh5 move at the end, but I failed to see how bad it was to give black a chance to put me in check. I would have settled for a draw.

[@user-zm1lx9uq9s]

Oh! I got it wrong. Great move!

In a real game can a grandmaster think and analize all that variations? How much time will he/she need?

[@adcyuumi]

All GMs are not the same. A lower end GM will not know this endgame at all, nor will they necessarily be able to read it out no matter how much time is available. A highest end GM, especially a player like Magnus who above other GMs goes out of his way to memorize endgames, will already know what to do and could play this endgame accurately (nearly) every time. It is easy to think of GM as a single homogenous group, but in reality there are enormous skill deficiencies even at that level of play.

I think, even a GM only in classical time format and not being in time trouble could find the right move for sure. And even perhaps not every GM, if he/she doesn't know from the beginning, that it is winning. With less time they can only rely on intuition, and luck can also make a roll, that if they found the real move for example between the logical Rh1 or Rh2, which is winning and which is only a draw. So if you follow some real chess games between GM-s with commentary and analysis, you can see, that even GM-s make mistakes sometimes in such a complicated endgames, like this. But of course, if you put this position as a puzzle to them, when they know, that the position is winning, they will solve it. The calculating time can depend on, which variation they consider first. If they consider first the right move, Rh1, then it will be much quicker.

From there position at 8m27 are there really no winning lines for white if playing Rh2? Thinking the discovered check gives a tempo which lets the whiteking reach the pawns

"Complex" [?] Fuggetabatit! YOU solve; I'll watch …

[@sverige1947]

I guessed right With the White Tower in H1! ✌️

[@WahrheitMachtFrei.]

Just using instinct I got it right...

[@williamd2999]

Dear friend, from time it would be nice if you put a puzzle that old people with a tired brain as me can solve , otherwise the site becomes a source of frustration, not of pleasure
