Pawn Race Endgame

Looking for feedback on the endgame starting with the trade at move 38. Please ignore the opening and middle game (which should be omitted but I am new with posting games).  I am only looking for thoughts the end game.

Note this game was posted in the game analysis forum but did not get any substantive feedback.

Thanks for your insight. 

43...Rd4? attack and defend

best of luck

But that doesn’t stop Ke3.

Thanks.

Very well played. What did you see after 43.Rxh6 that dissuaded you?

black should have tried to hold onto its passed pawn since that was blacks only hope.  that was a won endgame though

I am new to endgames, so I just wanted to see if anyone else found error with my play. I used the chess.com computer analysis and have included its suggestions, which I do not understand. Of note, it found error with 44. Ke2? and recommend Kg2. This is at least counter-intuitive as the recommended move takes the pressure off the black rook.

Another thought was 54. ... Ka2. I still think white would win, but it seems like the better move. 

nice endgame thnx
