When is the right time to resign or continue a game?

[jts]

If its a friend I'll give more time, and if it's an exciting game for both I will, but if one player has overcome repeated mistakes by using his time to read his way out of the holes he has made, then I don't think it's really fair for him to ask for even more time once he runs out.

[Phelan]

Yeah, I was not talking about people asking for time, I meant giving time to an opponent about to time out, even without him asking, if I'm invested in the game.

If you count, that you opponent can afford to make one big blunder and still be well ahead then it is good time to resign.

If only you would follow that rule Matti, I would have beaten you at London . But I made two big blunders and lost by 2.5 . Against me that rule should perhaps be modified to "if your opponent is in byo yomi, don't resign unless you are over 150 points behind", as I have been known to squander leads that large.

If you are ahead, don't resign

However, if your ahead, you have nobody.
