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

I play Scrabble Go from time to time. But I never know if I’m interacting with a real player or a bot. I miss the days when I could play with my coworkers. Two of them were professional players with official scrabble ratings. Right now, I’m looking for a reliable website to play scrabble online. It doesn’t really matter if they are beginners who play for fun or professionals. I want to know that I’m playing with a real player!
