Answers.Body: <p>There were a lot of inaccuracies by both players, I don't think you were ever losing, but you certainly threw away the win occasionally. I think three concepts might be helpful to you:</p>
  
  <ul>
  <li><p>A protected passed pawn is very strong in a pawn endgame because it forces the enemy king to keep an eye on it at all times. Therefore allowing 46…e4 was a big mistake that turned an easy win into a draw. Instead take on e5, play h5 and h6 and then round up the black pawns.</p></li>
  <li><p>Two connected passers are even stronger, because basically that's a dynamic duo of protected passers: The enemy king can never take the more backward one, because the other one will queen. And whenever possible, they will advance. See again move 46. If you take on e5 and black retakes with his king, you can fearlessly advance because as soon as the black king returns to g6 to attack the h6-pawn, you just protect it with g5.</p></li>
  <li><p>The king is often curiously helpless against two pawns that aren't even connected and just one square apart: That's why 50.c4 was another big mistake. If black takes this pawn, there is no way for you to get at either the e- or the c-pawn. So 50…dxc4 51.Ke3 c3 and you cannot take on e4 because the c-pawn will queen. (Edit: Dag points out that after dxc4 b5 might still win for white, so maybe it wasn't a mistake, but the concept is still useful. Instead of dxc4, b5 should draw for black.)</p></li>

Answers.Text: Agree with almost all of this. The key is to not allow Black's e4 -- 46.dxe5+ -- and then to "see" that Black's king will never be able to deal with both your e5 pawn and your h4 pawn without giving up all 3 remaining black pawns to your king. E.g. 46...Kxe5 47.h5 Kf6 48.h6 Kg6 49.h7 Kxh7 50.Kf4 Kg6 51.Ke5 Kg5 52.b5 winning d5 and the game.

  You made this endgame too exiting, when it should have been a simple win for white. The simple way to win was 46. dxe5, as have already been mentioned. After 50. c4?! chaos started, and I think you were even lost for a moment after the bad move 53. c5??, when the alternative 53. cxd5+! seems to be winning! Black returned the favor with the time-wasting move 54... d4?, when instead 54... b4! would have lead to big trouble for you. (Or maybe not. Perhaps you can run with the h-pawn and secure a draw.)
  The move 46. dxe5 has already been covered, so I will instead focus on the position after 47... Kg6.

  In this position there is nothing going on, which means you can improve the position of your pieces before doing anything drastic. So why not start with 48. g5 Kh5 49. Kg3 Kg6 50. Kg4 b5 51. h5+ bringing the pawns one step closer to the goal line. 
  After 51... Kg7 it's perhaps not immediately clear how white can make further progress, but at least you can play 52. g6 Kh6 53. Kh4 without risking anything. (Except you have ruined the perfect pawn formation with the connected passed pawns standing side by side.)
  The big decision comes after 53... Kg7. Can white play 54. Kg5 and let the black pawn run? It turns out they can, see the variation in the player window, where 56. Kf6! is another key move. White wins.
  This by the way is often the outcome in the battle between two connected passed pawns and a single protected passed pawn of the opponent. There's nothing particular about the position we are analyzing.
