How To Resign
To resign, say "I resign". Other approaches include nodding your head, a subtle approach which might only work in the Orient, placing two stones on the board (an illegal move), or placing one or more captured stones on the board.
The AGA tournament rules require that the player who wants to resign say so with a clear voice: "I resign."

In BadHabits, we have already mentioned that you should not wait to resign until the game is about to end. But one should not resign too early either. When suffering a big loss, it is wise not to resign immediately. Continue for several moves until your anger or disappointment has cooled down, and you are able to make a positional judgment. Only if this judgment shows that the game is really lost, is resignation appropriate.

 Bob McGuigan: This head nod is also something of a bow, indicating the superiority of the other player. I've seen it only between strong players, like pros, and I think it is understood by the opponent only when both players are strong enough to realize that there is an insurmountable difference on the board.
JTron: I live in an area where I see few "live" games, but went to an AGA tournament where everyone who resigned did so by smiling and offering a hand shake. At no point did anyone even say, "I resign." Is this normal for AGA? Or just a Northern California thing?
mafutrct: This is very normal in all tournaments I ever was at in Europe as well.
