Endgame: Quickest checkmate? Beginner question

Sort:

Hello fellow chess players,

I'm looking for some advice here... I'm a beginner and in this particular game I was wondering would have been the quickest option for me to mate the opponent. Instead it went on for a eternity, I tried not to cause a stalemate and in the end it ended in a draw due to repetition grin.png
Thanks in advance!
