I can't figure out how to respond to specifics comments on my phone.
When I read the original question I assumed we were talking bullet chess because longer games have too many clear answers. Maybe that's an unfair assumption.
Someone also mentioned analyzing which is another fair point. I like to analyze but I'd rather rematch and analyze later. I use lichess so the system might work differently. With bullet I only analyze a third or so of my games. If people rematched that'd be lower.
Maybe a better example of the psychological breakdown is people who will let someone undo a clear drop mishap and those who don't. This has very limited excuses. I'd bet the people who rematch are the same ones who prefer to lose a good game than win because of a misclick. Maybe I'm projecting.
Natarka,
I was talking about someone else, had nothing to do with you. Sorry if there was a mix up in the conversation. Nothing against you.
cool , I have no idea why other people decline rematch requests only why I do ... at my level it's really just a blunder fest so there's nothing to learn from playing me twice anyway !
