I have played a game against a 2020 elo player. We have reached this position:

3r2k1/R6R/4p3/4r3/4n2P/6P1/4PPK1/8 w - - 0 39

move to white

I have proposed the draw to the my adversary. He has accepted. I tasted of be in advantage, but by
win I must well know the ending. The engines it also say white in advantage. The games
among engines, end always with the victory of the white. But I am not successful to win a
game against the commputer. Then I ask you:
1° theoretically the white  has won, but in practice you do bright ideas of the position?
2° Which is the better line for the white?
Thank

Yes, but have you tried has play all the game without benefit of the computer? (without look the analysis)

The plan is simple. Hogging the king on the line 8, at the same time you support his pawns => line g and line h.
