Chess Etiquette after game

I am always confused on what is an appropriate thing to say after a game of chess.  Are there any general guidelines to what people say after game or is it different for every culture that people come from?  I really just don't want to come across as rude to people I'm trying to be courteous with.

When in doubt, say nothing.

JBHMD!

in general you should say 'owned' if you beat the other person and say 'nice engine' if you lose to him.

I say hi at the begining of game. I got no replies yet. Dont say anything

Just say GG (it's neutral) or say nothing at all.

I generally like to compliment them on the most complex move they found if they beat me. If they found it themselves they probably feel pleased and if they used an engine they probably feel ashamed. Seems like a good thing to do both ways.

I don't say anything

I had a great 30|30 game recently with a player rated 150 higher than me; it would have been my highest win to date if I hadn´t lost. It went to 85 moves with a R and Ps ending. The balance fluctuated a few times, I missed my chance of mate, then he ended up with an extra pawn. We´d written nothing at all for the whole game, not even "Hi!" at the beginning, then about 15 moves before the end he wrote "However this ends, very gg!" I thought that was great; no danger of apparent condescension, and we chatted a bit about the game afterwards.

Otherwise I do the same as FirebrandX; I say "gg" or similar if I lose but nothing if I win, unless my opponent says something. Seems the best way.

tHATS BECUSE MOST CHESSPLAYERS HAVENT EVEN SEEN A COMPUTER UNTIL A COUPLE OF DAYS AGO. aTLEAST WE KNOW HOW TO WORK KEYBOARDS FROM OUR TYPEWRITER DAYS.

I don't think it matters too much, but my last two games ended in my being called a cheat and being called a jerk respectively (I had not spoken on either occaision), so just try not to be as rude as that.

If you are playing online chess, there isn't no obligation to say anything at all including over the board (we will address this later), it would be fine to just simply play the game and leave, though over the board, social conventions encourages, a quick greeting, perhaps additional rules to adhere to and depending on the outcome and level of play, you alternate between "excellent game", "good game", "thank you for your time". 

If I lose I compliment them with ...Well done, thank you for the game....if I win I also say thank you ....I appreciate my opponents time playing with me.....is all about respect. 

If you win then great! Dont forget to shake your opponents hand and say good game, that is just proper.

If you lost you may be feeling a little down but dont cry or anything like that, you need to shake your opponents hand and say good game as usual. (Remember that you must learn from your mistakes)

I totally disagree with everything that ArtOrDeception copmmented earlier. In my oppinion the way he put it is if you lose that you should breg (which is never right) or if you loose that you cry and be a bad sport>

good luck (gl), and good game (gg) are always polite, if they take it as rude then they are just still upset from the loss. 

I always acknowledge my opponent with a smile and nod at the beginning (which is often ignored). A "thank you" and "good luck" at the end, win or lose. If my opponent appears open, I'll shake his (her) hand and ask if he (she) would like to do a post mortem (again, win or lose). I leave them alone if they appear upset, annoyed, smug, or closed.

I'm still chuckling after reading ArtOfDeception's post--hilarious!!! 

@ArtofDeception, I thank you for you insightful and informative post.  I now realize the grievous error of my ways at conclusion of play and will seek to remedy this immediately.  I have one question though.  In the event of a win, and my opponent immediately asks for a rematch.  Is a swift smack across the face appropriate?  

whats wrong with only a  gg at the end ....

so basically your saying just playing with a female is win/win
