@Luciano Ivanovich thanks!

Its happened to me. I've had numerous people ask for re-do or a takeback or whatever it's called on Lichess. I never let them. If you can't do it when playing over the board game why should you be able to do it online. Nonsense.

@Ebombayed Chesscareer Now I am a very novice player, but from what I can see, when your knight was on e5, black's king had one less square to use for an escape. (Plus you had no reason to move the knight). If you moved your queen to g4, she would you have been inline with the king, and you would have been one move closer to checkmate. That's just my observation, I am not an expert by any means
