1. Kg6 Ra8 2. Kf7 … Rh4 mate
1Kf7 Rh5 (forced)
2Kg6 (Black resigns)
Note: 1Kg6 loses because of 1…Ra8.
1.Kg6
the best is Rg5+, because on Re8 white plays 2.Kf7
after 2.Kxg5 there is some game, but white has a won position
Re8,Re7 draw by repetition by virtue of h3,Rh8 mate threats
Hi Susan Polgar,
Ref : “Weekend chess tactic” [White to move ]
Sub : White wins the game.
1. Kg6 Ra8
2. Kf6 a2
3. Rh4+ mate
White wins the game : 1 – 0

Kg6 ..
1. Kf7,Rf5 2. Kg6 and there is no defense
1. Kg6 threatening Re8# will simply win it for white.
Black has to play 1..Rg5+. If 1..Ra8 2. Kf7 threatening Rh4# will force black to play 2..Rf8+ and after 3. Kxf8 white can force mate in a few more moves.
1.Re8+ Kh7
2.Re7+ Kh6
3.Re8 if Kh5
4.h3 1-0
Black does best to move the king from h8 to h7.
Draw by perpetual check!
i think with 1.Re7 threatening mate with 2.Kg6 3.Re8. After 1.Re7 i think black will have 1..Kg8 1…Ra8.. when white can simple eat pawns with 2.Rb7
Kg6 and white wins, because black loses a rook..
Kg6…and hope black is busy queening the pawn 🙂
Re8 white wins.
1.Kg6 Ra8 2.Kf7 winning
Kg6, Ra8
Kf7
then mate with Rh5
How ’bout 1. Kg6 instead? Threatens immediate mate by 2. Re8. If 1…Ra8 to stop it, then 2. Kf7 restores the mating threat, this time by 3. Rh4++
This reminds me a lot of the end of the Saavedra position solution, where White underpromotes but wins by threatening mate and attacking Black’s rook simultaneously…
1.Kg6 (threatening mate on the 8th rank) Ra8 2.Kf7! (threatening mate again, now on h-file)

1. Kf7 threatens mate and forces …Rh5, then 2. Kg6 threatens mate and attacks (and wins) the rook. There’s a lot of work to do, but the rest should be a matter of getting the rook to the a-file, then advancing the k-side pawns.
1. Kg6 Ra8 2. Kf7 leads to Rh5# sooner or later
1. Kg6 Rg5+ 2. Kxg5 Kg7 3. Re7+ Kf8 4. Rxb7 a2 5. Ra7 Ke8 6. Kf6 Kd8 7. Ke6 Kc8 8. Kd6 Kb8 9. Ra3 Kb7 10. h4 … h pawn will promote
4. Re1 looks promising too
Did I miss anything?
1.Kg6 Ra8 (to prevent white’s Re8#)
2.Kf7 and black can’t stop white’s Rh4#
1.g4 pushing the pawn may be the idea
1. Kf7 looks like the same as 1. Kg6 but is different.
1.Kf7 Rf5+! 2.Kg6 Rf8 stops the mate
Therefore
1.Kg6! Ra8 2.Kf7 intending Rh5
The eye is drawn to the fact that there is a potential checkmate in both directions. Kg6 forces Ra8 Kf7 and all black can do is Rf8 Kxf8 and then white just chases the black king until opposition and the checkmate are forced.
Kf7 Rf5+ Kg6 a2 and perhaps black can get a queen before being mated
After analyzing all positions, it is clear this is by far the best:
(1) Kg6 Ra8 (Ra8 is black’s only options to prevent mate on next move).
(2) Kf7 (black’s move is irrelavant now, all hope is lost)
(3) Rh4(mate)
NOTE: black could possibly prolong by using Rf8 on (2) and sacrificing the Rook. In that case, mate is postponed but black’s position is significantly weakened and it is only a matter of time before black king is cornered.
Nobody seems to have noticed that after 1. Kg6!! black can escape immediate mate by sacrificing his rook:
1. Kg6 Rg5+
2. Kxg5 Kg7
But this is still white’s best move. 1. Kf7 is not so clear-cut as:
1. Kf7 Rf5+
2. Kg6 Rf8
