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.
Alena, you and I have different ideas about what "solved" means. What about black's options at move 1?
Arein22 1.Ke4 f5+ doesn't fail because of taking the pawn en passant.
It took me 11 minutes to solve it.
It's a winning position for white.
1.Rxg2 (is worth looking) Rxg2. 2.Kxf4 and now with proper play(white may win or draw)
But it also fails to f5+.
A nice puzzle,1.Kxf4 does not work because of Rf1+ and g1+Q.1.Ke4 is quite good.
