If you prefer to resign in such cases it's up to you, just don't pretend to set an example of high moral standards for others.
Geepers are you this harsh to all newcomers? Are you having a bad day or just grumpy in general?
Did you just set an example of harshness for others?
I raised a question based on a "feeling". It didn't feel right. So, I wanted to research what was normal etiquette versus rules.
I'm not a terrible chess player, but I know a few who are. I also know a couple people who are actually pretty good. And one thing we all have in common is that we do not expect other people to resign. I can't speak for them, but I personally have never once, in any game I've ever played, expected someone to resign. I expect every game I've ever played to either be finished by checkmate, draw, or agreed abandonment. I've had many games where we play for a while, then just agree to stop. Not agree to draw, just stop playing. We've also played a lot of times where we set up a position and start playing from there. But never once, under any circumstance, have I ever expected the other person to resign.
