Lesson learned - sometimes it is much better to under-promote!

This was a tough one - I struggled most of this game but stayed pretty even in terms of pieces.  Opponent had position and initiative for most of the game.  Still I hung in there and managed to get an advantage at the end and ended up in an end game with my king and two pawns to his king.  But I had bled off most of my time trying to get out of jams and only had about 5 minutes left and he had over 40.  

Got my pawns in position to convert.  Opponent had no way to block.  I had enough time on the clock to win.  Plan was to quickly promote the two pawns to queens and end it. . .

Opponent had a long think, finally moved his king in front of the second pawn.  Didn't bother me because that pawn was protected by my king.  Advanced the other pawn and promote it to queen and the game instantly ended. . .stalemate.  

I wasn't even looking for it.  He had no safe square to move to. . .If I had converted to a knight he would have been in check.  

Ugh - definitely a game I should have won there. . .

Underpromotion is not the right lesson to learn from this position. In my opinion there are at least a couple that are more valuable:

1. Don't play too quickly, always think before you make a move. You say you had 5 minutes left, that is a lot of time.

2. When your opponent only has a king, all you should think about is stalemate.

 Well since promoting to a queen instantly created the stalemate I disagree.  But, yes, obviously I should have been thinking about the stalemate and definitely would have - it just didn't occur to me that a stalemate could result from promotion of a pawn.

1. h8N+ is not the best move. Instead, any king move breaks the stalemate trap and you can promote to a queen next move. According to Stockfish, 1. Ke5 is the fastest.

You're right - I hadn't thought of that.

Yes, sometimes it is better to under promote.  I learned my lesson a long time ago.  I promoted my pawn to a queen and accidentally stalemated my opponent.  I believe that if I promoted my pawn to a rook, then I wouldn't have stalemated my opponent.
