A First Prize Winning Ending Study From 2017

How quickly can you work out white's winning plan here? This is a good one.

8/5p2/8/4K1P1/5p2/7P/4R1p1/1k4r1 w - - 0 1

1.Rxg2 (is worth looking) Rxg2. 2.Kxf4 and now with proper play(white may win or draw)

It took me 11 minutes to solve it.

1.Ke4 Rh1
2.Rxg2 Rxh3
3.Kxf4 Rh1
4.Rf2 Re1
5.Kg4 Re7
6.Kh5 Kc1
7.Kh6 Rc7
8.Rf5 Kc2
9.Kg7 Kd3
10.Rxf7 Rc1
11.g6 Kd4
12.Kf6 Rf1+
13.Ke7 Re1+
14.Kf8 Ra1
15.Rd7+ Kc3
16.g7 Rf1+
17.Rf7 Ra1
18.g8=Q Ra8+
19.Kg7 Rxg8
20.Kxg8
It's a winning position for white.

Arein22 1.Ke4 f5+ doesn't fail because of taking the pawn en passant.

Alena, you and I have different ideas about what "solved" means. What about black's options at move 1?

Arein, It isn't crazy to look at 1.Rg2, but sacrificing the rook for the two pawns is hopeless to hold even a draw for white- the time it takes the white king to get to the f7 pawn, or just to get the king into a position to exchange it for the white g-pawn takes too long, and the white king can't advance the h-pawn without black putting the rook behind it tying the white king to it just to protect it.

Yes, you are right Yancey. I solved the easiest variation of this puzzle.

Yes it is,But if black blunders a move then the game is over.Ke4 is the correct one

It took me one hour to solve these variations.

Ok, Alena, this is much better. Now focus on V-2 in this critical line- 1.Ke4 Kc1! 2.Kf3 Rh1 3.Kg2! f3 4.Kf3. You now need to consider one more option for black here at move 4 that isn't a transposition of any other line you discussed.

1.Ke4 Kc1!
2.Kf3 Rh1
3.Kxg2 f3+
4.Kxf3 Rxh3+

It's a win for white.The sixth move is hard to find.
