If he's a good person, I say good game. If he's a relative or an obnoctious player, I say Hasta la vista, baby, Aaaaaaaarnold style! If he's a younger player, I ask him if he would like to analyse the game where I would show him his good moves ans his blunders. All and all, I can be professional and a gentelman or I can rub it in his face. Lastly, during a tournament I would just shake hands and say good game and best of luck.
What do you say one move from mating your opponent!

Wow, you have been bumping this thread for a week. Well, here is your response.
Better bump than spam.... .
Chess in the military could be a little deafening....

I say "HEY!! WHATS THAT OVER THERE??" then i slip another queen on the board, while their back is turned.
Mate in one.

"If they be any reason why you think I should not mate you, you may speak up now or forever hold thy piece"

"You can check-out anytime you like, but you can never leave." Then my opponent excuses himself to the bathroom, while not resigning beforehand, not to be heard from for several days...
It is not against the rules to talk to your opponent during the game. wtf!? this isn't some mime session where you can't speak; it's just a chess game lol

Lol... Did you hear tyres screeching outside?

Not sure what tyres have to do with it, but when my opponent goes to the bathroom, he may not be leaving the Hotel California, but an extended vacation in the bathroom is just as good as leaving...
