Have you ever forgiven your opponents Blunder?

Have you ever forgiven your opponents Blunder? Why yes and why no?

In simple definitions I have given them a Takeback if it's a Mouse Slip or something like that. Or else if you forget to take advantage on the move which your Opponent Blunders it has a specific term for that called as "Double Blindness" Sportsmanship should be there and indulged in all humans.

I have noticed a marked increase in people asking for take backs. I allowed it at first but have since stopped as we are playing rated games. You also never know if someone is just playing you.

@ChesswithFitness Chess is a war over the board. The object is to crush the opponent's mind- booby fisher

If it is an unrated game, I probably allow it but if it is a rated game, no.

I let retake people OTB every move unless they were trash talkers. Online I do not. I tournaments it is against the rules so I also do not.

I only forgive my opponent's blunder when it is a misclick

I will allow if it is clearly a mouse-slip, for example moving a rook from a1 to g1 when it was obvious they intended to play h1.

On the other hand, if they move a pawn hanging a piece, then sorry, but that's a blunder and I will not accept a take-back request.

Unfortunately some people take this really badly and will hurl abuse, even during a rated game.

Really, I usually only play bullet games 1+0, so I don't usually offer takebacks, because even if the opponent allows the takeback, you lose enough time to be crippling. As for punishing blunders, I usually only notice them in hindsight, and just feel a mild twinge of annoyance that I didn't notice it. When I do notice the blunder, it depends how much of an advantage the other person has.

Somtimes, even when it's worst for me.
Always if it's a mouse slip -Eg moving the king by one instead of castling (even tho I had peoples resigning right after the takeback anyway)
