I have flagged people and gotten flagged many times. Personally, I do not think it is unethical, but what are your opinions and the reasons? Do you think it is okay for a person to win via flagging?
The ability to manage your alloted time is one of the key aspects of the game.
A chess player who complains that he only lost because he ran out of time is like an automobile driver who insists that he only had an accident because he was drunk.
this is a terrible comparison. You are indirectly implying drivers should be training to be able to drive drunk without accidents or its just a skill issue
flagging my apponent is what makes chess fun, chess would be meaningless without it.😥
