Andrea is cute. The other one is ok. Their chess is meh. Now people are going to come on and insult my rating, but I don't pretend to be a chess expert on stream. Anyhow they figured out a way to make money without having to go to a soul crushing day job, so good for them. Let's see how it goes when their looks start to fade.
Totally wrong. Alexandra is way "hotter" than Andrea, at least in terms of traditional attractiveness (and also way less annoying than Andrea, but let's not go there). Alexandra is also 7 years older than Andrea and taught her younger sister the rules of chess, how to stream, get an audience, etc. So really Alexandra has been leading the way for both sisters for a while now.
Watching one of their videos:
Wife: oh, they're cute, are they good chess players?
Me: Wait a minute, they were playing chess?
Cue the fireworks.
