Thoughts on Sandbagging?

if a 2k player is letting a lower rated player checkmate, they’re helping the person learn patterns of the game to win in the future
You mean sandbagging before joining the arena or during the arena?
If before joining the arena, no, because it gives you an unfair advantage, the pairings are usually rating-based and also, higher rated players might play differently against lower rated players to get quick wins, so the sandbagger can take advantage of this.
If during the arena, I don't think it's that bad, because it doesn't hurt anyone in an unrated arena...
I don't really no the context, but if the higher rated player feels bad for stomping/or for fairer matchmaking - I think there is a balanced game setting where the higher player starts with less pieces.
whats sandbagging?
Purposely losing games or manipulating rating to gain an advantage
Should I allow it in my club? Yes or no, and why?
