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

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
1.Ke4! Kc12.Kf3 Rh13.Kxg2 f3+4.Kxf3 Kd15.Rf2 Rxh3+6.Ke4 Rh77.Ke5 Ke18.Rf5 Ke29.Kf6 Kd310.Rb5 Ke411.Rb7 Rh112.Rxf7 Rf1+13.Kg7 Rg114.g6 Ke515.Rb7 Ke616.Rb6+ Ke717.Kg8 Rh118.g7 Rh219.Rb4 Rh120.Rf4 Rg121.Kh7 Rh1+22.Kg6 Rg1+23.Kh6 Ke624.Kh7 Rh1+25.Kg8 Ke526.Kf8 Kxf427.g8=QIt's a win for white.

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 Rh13.Kxg2 f3+4.Kxf3 Rxh3+5.Kg4 Kd16.Re6 Rh27.Rf6 Rg2+8.Kf5 Rf2+9.Ke5 Rg210.Rf5 Ke211.Kf6 Ke312.Kxf7 Rb213.g6 Ke414.Rh5 Rb7+15.Kg8 Rb216.g7 Rb8+17.Kh7 Rb718.Kh8 Rb8+19.g8=QIt's a win for white.The sixth move is hard to find.
