Ok, mine are -
Never ask/expect the other person to resign simply because you think it is a lost position - there is learning in losing to the end. If not anything, the person can learn lessons about the endgame.
Don't say good game if it was not - it can sound condescending/sarcastic. I might be wrong on this one though
Just wondering if there are any pieces of chessicate (chess-etiquette) people would like to see as standard. Mine would be as follows:
Resign when you have lost don't waste everyone's time
Say good game
Be a good sport - no abuse/bad looser-ship
any ideas?
