OP, I can really understand your celebration when winning against someone using outside help. I probably would have done the same. Just keep the gloating to a minimum after the event.
When Trivial Pursuit came out in the early 80's, one guy at the university student housing bought the game. He would strut around and tell everyone how good he was at it, ALL THE TIME! Actually, in his mind, he was perfect at everything. At one point, I told him to sit down and play with me. I won (thank you Mme Curie) and it was a sweet victory. He toned it down after that. Strangely enough, he never asked me to play again.
