Should this Feature be?

I would like if there was a feature to Have take backs by Agreement of both Players and For example if white asks for a take back, then black if Black allows, they would get An Achievement like that.

Just think of adding this Feature.

im pretty sure unrated daily games have a takeback feature

Mulligans? Not sure it would work here.

I think takeback by agreement would be great, but no need for the acheivement

Yeah but Achievements will encourage people to Allow take backs

Takebacks are allowed in unrated games. Here's a link: https://support.chess.com/en/articles/8594400-can-i-take-back-a-bad-move

yes there should be a feature to take back because many TIMES both the players know that its a is miss click

I know but I am talking about RATED GAMES

no that's basically just cheating

although I think misclicks should be able to be appealed (i.e rating compensation or smth)

If they're ever added to Live games, they'll always only be unrated.

Well, it wouldn't be cheating, because it would be like a draw where both players have to agree

Are we trying to make this lichess?

Yeah

There ought to be take backs. Just as an option

What are mulligans?

But why would people want to encourage takebacks?

To increase Sportsmanship

Take backs could decrease sportsmanship with the back spamming and anger if they're not agreed to
