Answers.Body: <p>Overall you played a wonderfully strong game. White played weakly, and you used that to your advantage. I plugged the game into Stockfish to see if the computer could find any moments of missed tactical shots. Here are answers to each of your four questions.</p>
  <ol>
  <li><p>Instead of playing 4... exd5, next time you could play the Stockfish recommended 4... g6. It is slightly better, preparing to fianchetto the bishop and gain a marginal lead in development</p>
  </li>
  <li><p>You missed a chance in the middlegame. 20. b4?! was in fact an inaccuracy by White. This is because you have a battery comprised of your queen and bishop on the a1-h8 diagonal. 20... Qxa1! is in fact the best move, giving up the queen for two rooks. Black now has a much better position.</p>
  </li>
  <li><p>Your move 29... Re2+? indeed misses an opportunity as you suspect. There was a chance to win a piece. This is because of the move 29... a4!, and White must give up a piece for Black’s passed pawn at some point. If White plays 30. Bxe4, Black wins the White bishop via a discovered check from the rook. If White moves their king to h1 avoid it, 30... a3 is next. Now White’s light-squared bishop cannot reach it. White's rook will have to capture the promoted Black piece, if not take the pawn earlier, as Black’s dark-squared bishop protects the promotion square.</p>
  </li>
  <li><p>I think that what you consider the endgame is after the rooks are exchanged. As such, I will answer this question regarding the moves that happen after 31. Kxe1.</p>
  </li>
  </ol>
  <blockquote>
  <p>Playing your pawns out to get a passed pawn and activating your king are good, standard practices. All in all, you played this endgame more strategically than White did, although you did miss a few moves. It also boils down to the fact there were no stronger moves that White made. White’s attempt to create their own passed pawn was a natural strategy, but it was not perfect. Yours wasn’t either, but it was superior.</p>
  <p>After White played 35. g3?!!, a blunder, you were correct to play 35... Bg1. While 37. g4?! was another blunder, you missed the better move 37... f4! gaining a second passed pawn. After 43. Kc6? you should have played 43.. a4! instead, the second time you didn't see it. After 44. Bf5 a3 45. Bb1, 45... h4! is the move to play, and would have promoted soon.</p>

  Overall you played a wonderfully strong game. White played weakly, and you used that to your advantage. I plugged the game into Stockfish to see if the computer could find any moments of missed tactical shots. Here are answers to each of your four questions.
  
  1. Instead of playing 4... exd5, next time you could play the Stockfish recommended 4... g6. It is slightly better, preparing to fianchetto the bishop and gain a marginal lead in development
  2. You missed a chance in the middlegame. 20. b4?! was in fact an inaccuracy by White. This is because you have a battery comprised of your queen and bishop on the a1-h8 diagonal. 20... Qxa1! is in fact the best move, giving up the queen for two rooks. Black now has a much better position.
  3. Your move 29... Re2+? indeed misses an opportunity as you suspect. There was a chance to win a piece. This is because of the move 29... a4!, and White must give up a piece for Black’s passed pawn at some point. If White plays 30. Bxe4, Black wins the White bishop via a discovered check from the rook. If White moves their king to h1 avoid it, 30... a3 is next. Now White’s light-squared bishop cannot reach it. White's rook will have to capture the promoted Black piece, if not take the pawn earlier, as Black’s dark-squared bishop protects the promotion square.
  4. I think that what you consider the endgame is after the rooks are exchanged. As such, I will answer this question regarding the moves that happen after 31. Kxe1.
  
  > Playing your pawns out to get a passed pawn and activating your king are good, standard practices.

White’s attempt to create their own passed pawn was a natural strategy, but it was not perfect. Yours wasn’t either, but it was superior.

Kc6? you should have played 43.. a4! instead, the second time you didn't see it. After 44. Bf5 a3 45. Bb1, 45... h4! is the move to play, and would have promoted soon.
