How should I have won this endgame?

I was winning in this endgame, then I wasn't winning, then I was winning again, then I had to settle for a draw. I would like to know what I should have done in the endgame. Of course, if I could have played better in the opening or middlegame, I would like to know that, too. This was an OTB tournament with a 110+10 time control. Time pressure wasn't a factor. If anything, I might have played too quickly, since I had much more time than my opponent when the game ended. I have not done the computer analysis. After the game, we spoke briefly, and my opponent said I should have put my rook on the second rank. I wasn't sure on which move I should have done this, and wasn't sure that my rook could have handled the queenside pawns if I had done this.

Great post, great game.

I wish there were more posts like this.

I'll just share my opinions, excuse my inaccuracies and generalizations, I only analyzed briefly.

Thanks for sharing!

Thanks for looking at my game. I wish more players posted annotated games, especially classical OTB games.

np,

I post my games from time to time if there's one that feels important... always 0 - 2 replies and the 2 are normally not concrete at all lol

Thank you for posting this game. I don't understand why he pushed the a pawn and played Na4.

OP said it was classical, but I guess they were fatigued from a long tense game
