Hello,
I also wondered about the abort logic, and came up with three reasons;
1. They don't want to lose the challenge, and accept it. They quickly go back and study the opponents stats and decide their odds of defeating them. If they don't think they can win, they abort!
2. My second thought is all about how many points they may win or lose by playing this game. They seem to be more concerned about the points then a chess match.
3. Final reason, if your level of play is way far below their ability the game isn't worth it for either of you?? On the other hand there are some players that will play you knowing they will win and gain a couple of points. One should respect the the point system, and try to play within their range, or higher.
I can understand the reason for a game abort to some degree, but I do seem to get a lot of them from time to time. Why is it folks abort a game. Is it something I am doing? Just a wonder...
