White to move. Is this a win or draw? No computer analysis please.
7k/5K1p/6p1/6P1/7P/8/8/8 w – – 0 1
Easy win.
1.Kf8 h6 (1..h5 2.Kf7 Kh7 3.Kf6 and 4.Kg6:) 2.h5! and no matter what Black plays white will queen on the g-file
1.Kf8 h5
if 1…h6 2.h5 (or Kf7)
2.Kf7 Kh7 3.Kf6 wins
Not dificult but instructive
Win!
Kf8 h6
h5 kh7
kf7 hg
g6+ and white wins.
1. Kf8 h6
2. Kf7 Kh7
3. Kf6 hg5
4. hg5 Kh8
5. Kg6 Kg8
6. Kh6 Kh8
7. g6 Kg8
8. g7 and white wins.
And, if black plays h5, white will win both pawns outright.
1. Kf8 h5
2. Kf7 Kh7
3. Kf6 and white wins both pawns.
So that leaves us with, in the first line,
1. Kf8 h6
2. Kf7 Kh7
3. Kf6 hg5
4. hg5 Kg8
5. Kg6 Kh8
6. Kf7 Kh7
7. g6 and white wins.
It looks like a win for white to me.
1. Kf8 h6 2. h5!
In general, once the opponent gets control of a queening square on a rook file, it is difficult to queen a pawn on that file. In this example, White’s best chance is therefore to try and queen a pawn on the knight file; therefore, White should, if possible, maintain control of the queening square on the knight file.
Also, since the White pawns are further advanced than their Black counterparts, White has a time advantage and will win a pawn race.
These ideas suggest the following line:
1. Kf8 h6
2. h5! Kh7
(If 2… hxg5 3. hxg6 wins;
and if 2… gxh5 3. g6 wins.)
3. Kf7 Kh8
4. hxg6 wins.
1. Kf8 h6
2. h5!
Should win for white
It’s a win!
1. Kf8! h6 (zugzwang)
2. h5!! and white gets a passed pawn on the g file that queens.
Note that 1. Kf8 h5 is also lost for black due to 2.Kf7! Kh7 3.Kf6 and both black pawns are lost.
I think it’s a win after
1. Kc8 h6
2. h5!
If 2… Kh7
3. Kf7 hxg
4. h5xg6+ Kh8
5. g7+ and white will queen
If 2… Kh7
3. Kf7 gxh
4. g6+
If 2… gxh
3. g6
If 2… hxg
3.hxg6 followed by g7+ g8 = queen
1 Kf8! and then:
A: 1… h5 2 Kf7 Kh7 3 Kf6 +- black must cough up his pawns and white has an easy win
B: 1… h6 2 h5! Kh7 ( 2… gh5
3 g6 or 2… hg5 3 hg6 lead to mate) 3 Kf7 and white wins.
-Justin Daniel
this one is easy
1 Kf8 h6 2 h5 ! and a white pawn will go on g6 g7 g8=Q
It’s a win:
1. Kf8 and 2. Kf7.
Should be a striaghtforward win for white, no?! Just 1.Kf8 h6 2.Kf7 Kh7 3.Kf6 and game over.
By the way: Karpov just lost again in San Sebastian, now 1/8. Painful to watch, really…
I guess white wins after Kf8,h6(if h5,Kf7,Kh7,Kf6!)Kf7,hxg6,hxg6,Kh7,Kf6!
sorry.I think after Kf8 h6 Kf7 hxg6 hxg6 Kh7 Kf6 Kh8! Kxg6 Kg8! and the position looks draw to me
1.Kf8 h6 (1…h5 (2.gxh5 leads to draw) 2.Kf7 Kh7 (2…hxg5 3.hxg5 Kh7 4.Kf6) 3.Kf6 (black loses both the pawns and game)) 2.Kf7 Kh7 3.Kf6 hxg5 (3…Kg8 4.Kxg6 hxg5 5.hxg5) 4.hxg5 Kh8 (4…Kg8 5.Kxg6 Kh8 (5…Kf8 6.Kh7 winning for white) 6.Kf7 (white winning)) 5.Kxg6 Kg8 6.Kf6 Kf8 (6…Kh8 7.g6 Kg8 8.g7 (white pawn queens))7. rest is history. Did I miss something here?
Looks like a win with 1. Kf8:
1…h5 2. Kf7 Kh7 3. Kf6 wins both pawns; or
1…h6 2. h5! Kh7 (2…gxh5 3. g6; 2…hxg5 3. hxg6) 3. Kf7 and depending on Black’s move White plays g6+ or hxg6(+) next queening.
1 Kf8 h6 2 h5 wins
Olimat
1. Kf8, h6
2. h5, gxh5
3. g6 and white wins
if
2. …, hxg5
3. hxg6 and white wins
1. Kf8, h6
2. h5, gxh5
3. g6 and white wins
if
2. …, hxg5
3. hxg6 and white wins
White wins.
1 Kf8 and if 1…h6 then 2.h5 and if gxh5, then 3.g6 queens, if hxg5, then hxg6 and again queens first.
if 1…h5, then 2. Kf7 Kh7 and 3. Kf6 forces black king away and wins both pawns and the game.
Hope this right.
treetown
1. Kf8 h6 2.h5 and wins (hxg5 is followed by hxg6-g7+ and so on while if gxh5 g6-g7+ and wins)
If instead B plays 1…h5 W wins easily after 2. Kf7 Kh7 3. Kf6 and the pawns fall
It’s a win.
1. Kf8 h5 (… h6 2. h5 gxh5 [ 2. … Kh7 3. Kf7 +- ] 3. g6 +-) 2. Kf7 Kh7 3. Kf6 +-
White wins by 1. Kf8 . . . forced move for black. And white will be left with one queening pawn.
Isnt white winning after Kf8,sooner or later black king is in zug-zwang
Kf8
1. Kf8 h6 2. Kf7 Kh7 3. Kf6 h5 4. Kf7 Kh8 5. Kg6 Kg8 6. Kh6 Kh8 7. g6 Kg8 8. g7 Kf7 9. Kh7 and White wins
White wins: 1.Kf8! (forces a pawn move) h6 [-h5 loses both pawns in the end] 2.Kf7! Kh7 3.Kf6! and in all lines, white gets his king in front of his remaining g-pawn and wins.
1. Kf8 (this move is easy to find as it is ‘forced’), h6 2. h5! (the clew), Kh7 3. Kf7 +- as black cannot avoid white playing g6+ or hxg6+.
Best wishes from Germany

1.Kg8, h6
2.h5!!, gxh5
3.g6!, h4
4.g7+, Kh7
5.g8:Q+, Kh6
6.Qg6++
trivially easy win.
1.Kf8 h6
2.Kf7 hg
3.hg Kh7
4.Kf6 Kh8
5.Kxg6 Kg8
6.Kf6 Kf8
7.g6 Kg8
8.g7
or:
2. Kh7
3.Kf7 h5
4.Kf6
Only way to go wrong is:
1.Kf8 h6
2.gh?? Kh7
with a draw
OK, I’ll give this one a try:
1. Kf8 h6
(If 1. … h5, then 2. Kf7 Kh7 3. Kf6 and White captures both Black pawns for an easy win.)
2. h5! Kh7
(If 2. … hxg5, then 3. fxg6 or if 2. … gxh5, then g6 and in either case a White Pawn promotes.)
3. Kf7 and White wins, with variations similar to those on move 2.
White Wins…
1. Kf8, h5 2. Kf7, Kh7 3.Kf6 and White picks up both pawns…
1. Kf9, h6 2. Kf7, Kh7 3. h5! and white wins as he will advance a pawn on the g file which black cannot stop.
a draw
White should win after 1.Kf8 h6
If 1….. h5
2. Kf7 Kh7
3. Kf6 would win both the pawns.
2. h5! Kh7
If 2…… any other move
3. hxg6! promotes.
3. Kf7! and white manages a pawn on g6 and wins.
It is a win for white. With 1.Kf8 a6 or a5, 2.Kf7 all other variations for black will lead to a loss.
I think 1.Kf8 h6 (h5. 2.Kf7 Kh7 3.Kf6 and white will take both blacks pawns) 2. Kf7! now black has three moves:
2…h5 3.Kxg6 and so on
2…hxg5 3.hxg5 Kh7 (protecting the pawn) 4.Kf6 Kh8 (has to move away) 5.Kxg6 Kg8 (taking opposition, but whites king is to far advanced) 6. Kf6 Kf8 7.g6 Kg8 8.g7 Kh7 (only move) 9.Kf7 and the pawn will queen and win the game.
2…Kh7 3.h5! gxh5 (if any other move white will take on g6 and safely march to the queening square) 4.g6+ and white will queen long before black and wins the game.
It is time for Jiu Jitsu Chess
I do not see a win for white. Therefore it is a draw. And – no, I did not use a computer!
1. Kf8 h6
2. Kf7 hxg5
3. hxg5 Kh7
4. Kf6 Kh8
5. Kxg6 Kg8
6. Kh6 Kf7
7. g6+ Ke6
8. g7 Kd5
9. g8Q+ White wins.
Win.
1. Kf8 and now
1. … h5
2. Kf7 Kh7
3. Kf6 wins the g pawn and then the h pawn.
or
1. … h6
and now White can’t play
2. Kf7?? hxg5
3. hxg5 Kh7
4. Kf6 Kh8
5.Kxg6 Kg8 drawn
but White wins with
1. … h6
2. h5! and after either
2. … hxg5
3. hxg6
or
2. … gxh5
3. g6
White promotes the pawn and wins.
(Black can’t pass with 1. Kf8 h6 2. h5 Kh7 because of 3. Kf7 and again a White pawn appears on g6.)
———–
But this looks incredibly easy, so I’m evidently missing some trick.
1) Kf8 h6 (forced )
2)Kf7 ! hg5 (either now….either after…it will happen tha same position)
3)hg5 Kh7
4)Kf6 Kh8
5)Kg6 Kg8
6)Kh6 ! 1-0
WIN! 1. KF8 H6 2. H5!!!!!!!!! 😀
1.Kf8 h6 (1.-h5 2.Kf7) 2.h5 Kh7 3.Kf7 winds
1. Kf8
[A] 1… h6 2. h5 gxh5 3. g6
or
2 …hxg5 3. hxg6
[B] 1…h5 2. Kf7 Kh7 3. Kf6 and White wins all Black pawns
At first sight I would move 1.Kf8! h6 (forced) 2.Kf7! hg (again forced) 3.hg Kh7 4.Kf6! Kh8 5.Kxg6 and wins
1 Kf8! h6 (forced)
2 Kf7! hg
3 hg Kh7
4 Kf6 wins
2 … Kh7
3 h5 !!! and wins
