Hi Susan polgar,
Well,now I had worked out the solution for this puzzle but anxious to know,others approach to this puzzle.
So,I will post my solution tomorrow.

1. g6+ fg
2. Kg7 …
creates zugzwang for White. Black will pick up both of White’s pawns.
1. … f6+ 2. exf6 Kf7 3.Kf4 Kxf6 with a draw. I guess this is the most safe approach for black to get a draw…
1…f6 2.exf6+ (If 2.Kh5 fxe5 3.Kg5 Kf7 4.f6 e4 5.Kg4 Kxf6 6.Kf4 Ke6 7.Ke3 Ke5 8.Kd2 Kd4 9.Ke2 e3 10.Kd1 Kd3 11.Ke1 Kc2 white wins)2…Kf7 3.Kh5(or h6)Kxf6 and white’s remaining pawn is again captured and Black’s king is able to move to c2
Interesting position 🙂
1. … f6+
2. fxe6 Kf7
4. Kh6 Kxf6
5. Kh5 * Kxf5
and the white king moves towards b1
if 5. Kh7, Rb8 6. Kh6 Rh8#
if 2. Kh5 (instead of fxe6)
2. …. fxe5
and wins
Very simple one.
But a beautiful one.
1……. f6+!!
2. exf6 Kf7! (Zugzwang!)
3. Kh6!
( If 3. Kh5 Kxf6 and the zugzwang forces a quicker finish.
4. Kh6 Rh4 #)
3….. Kxf6
4. Kh5 Kxf5 and the black king starts marching towards ‘c2’
0-1.
1. … f6+ wins for Black! White’s King is poorly placed, to put it mildly!
1… f6 2.exf6 Kf7! Zugzwang
This is a very pretty zugzwang position. Given that white is about to play a move like e6 to liquidate down to a drawn position, black needs drive the white king to the right and steal a king march to the b-pawn. Sacrificing the f-pawn is the right strategy, and from my eye, the only obvious move, even if you can’t see the zugzwangs that arise later:
1. …..f6!
2. Kh5
I will cover ef6 later. Continuing:
2. …..fe5
3. Kg5
Here, the alternatives are no better as white loses both pawns and ends up in a totally lost ending: [3.f6 Kf6 4.Rf1 Ke6 5.Rb1 e4 6.Kg4 Ke5 7.Kg3 Kd4 8.Kf2 Kd3 9.Rd1 Kc2-+]; or [3.Rg1 Kf6 4.Rb1 Kf5 5.Rf1 Ke4 6.Re1 Kd3-+]. Continuing:
3. …..Kf7 (e4 ok, too)
4. f6
Or [4.Kh5 Kf6 5.Ranywhere b1Q-+]; or [4.Kh6 Kf6 5.Kh5 Kf5 -+]. Continuing:
4. …..e4
5. Kf4
Or [5.Kf5 e3 with e2 and e1Q to follow-+]. Continuing:
5. …..Kf6
6. Ke3
Nothing better, and there is a trick to this move. Continuing:
6. …..Kf5!
A hasty Ke5 draws almost certainly since white can play 7.Rb2!! since it is stalemate if black recaptures the rook at b2. I have actually had someone do this sort of stalemate maneuver to me in an online game before, and I have never forgotten it. Continuing:
7. Ke2
Again, the alternatives still lose: [7.Kf2 Kf4 8.Ke2 e3 9.Rf1 Ke4 10.Rh1 Rc4! (10. …b1Q? 11.Rb1 Rb1=) 11.Rh4 Kd5 12.Rh1 Rc1-+]; or [7.Kd2 Ke5 8.Kc2 (or 8.Ke3 Rb3 9.Kd2 Kd4 10.Kc2 Kc4 11.Rb2 Rb2 12.Kb2 e3 13.Kc2 Kd4! 14.Kd1 Kd3 15.Ke1 e2 16.Kf2 Kd2-+) 8. …Kd4 9.Rd1 Ke3 10.Re1 Kf2 11.Rb1 e3-+]; or [7.Rf1 Ke5 8.Rb1 Rb3 9.Kd2 Kd4-+]. Continuing from move 7 above:
7. …..Ke5
8. Ke3
Any other move, and either the black king penetrates, or black just plays Rb3 cutting the white king off from the third rank followed by penetration of the black king. Continuing:
8. …..Rb3
9. Kd2 Kd4
10.Kc2 Rb5
11.Rd1 Ke3
12.Re1 Kf2
13.Rb1 e3-+
Finally, back at move 2, white does no better with capturing at f6:
1. …..f6+
2. ef6 Kf7! (only winning move)
3. Kh6
Or [3.Kh5 Kf6 4.Rmove b1Q or 4.Kh6 Rh4#]. Continuing:
3. …..Kf6
4. Kh5 Kf5
5. Rf1
Or 5.Kh6 and the black king just marches over to the b-pawn to drive the white rook off of b1. Continuing:
5. …..Ke4 and black walks the rook down and forces white to give the rook up for the pawn, winning the game.
1…f6+
2.exf6+ Kf7
3.Kh6
(3.Kh5 Kxf6 4.Kh6 Rh4#)
3…Kxf6 4.Kh5 Kxf5 White K is far off and it is easy for black.
2.Kh5 fxe5
White can not play a waiting move since 3e6+ would not be good for black.
3.Kg5 e4
4.Kf4 Kf6
5.Ke3 Kxf5 black wins
