What kind of opponent do you prefer to play with as a Scrabble player?

First of all, someone who doesn’t cheat. I’ll never play with cheaters. And I don’t know if you feel the same but cheating is probably double annoying since it’s a game that relies on knowledge and memory. And I like playing with someone who can actually take losing it.
A sore loser can easily take all the joy out of my victory. Most importantly, someone who does not insist on the existence of a word that doesn’t have a meaning in the dictionary. Basically, play by the rules, and I’ll enjoy competing with you.
