Does black have to mate?
Hintless Puzzle #2

ivandh are you just being funny ? I presumed if is it Black to move black should be winning this game.

Its not about winning or loseing, its about getting your king to the other side man
do you take this seriously

OH- Just noticed the "Bongcloud" caption...now I get it (yes, that works, too)
@kco: Got the message - done.

I don't think so I think is about winning the endgame here. So I am not sure

Are these hints or what?!
Perhaps the idea is to salvage a draw.
Could be a draw BorgQueen :-)
I think that the idea is that if any white pawn(except h7) is forced to move black will win.
So i think that the solution is Rh8 to force the white king to either leave the h7 pawn or get trapped in a stalemate situation if he tries to take the rook.
Kg8 seems to work too..

Spoiler Alert ! Answer will given down below.
Alexei Shirov vs Levon Aronian, Tal Memorial, Moscow 2006.
The event should have revived memories of the late Mikhail Tal's mercurial brilliance, but much of the play proved pedestrain.
This endgame provided a rare magical moment. The obvious play is 1....Rh8 2.Kg7 Rf8 3.h7 Rf7+ 4.Kg8 Rf8+ 5.Kg7 Rf7+ 6.Kg5 Rh7 with a draw.
Then all-time No.1 Garry Kasparov, watching on the internet, remarked: "The key to the position is White's b2 pawn."
Sounds bizarre, but Kasparov was not joking. Work out how the game ended, with Black to move, and you will see what he meant.
Solution- 1...Rf7 2.h7 Rf8 3.Kg7 Rh8 ! 4.Kxh8 Kf7 (White's king is trapped so he can only make pawn moves) 5.d5 cxd5 and now White must advance 6.b4 cxb3 en passant 7.c4 b2 8.cxd5 b1=Q 9.d6 Qb2 mate. The rare pawn capture en passant rule decide the game in Black's favour.
