The dynamic name idea is pretty good. It allows you to identify a fish for the day, but not to bumhunt him for eternity. It also prevents pros from angle-shooting by leaving and coming back shortly after, and pretending to be brand new players.
However, the dynamic expressions suck.
Their software is basically going to commit the cardinal sin in poker: The venue telling a player he is bad.
Most people who play poker -- even the fish -- have a delusion that they're far better than they actually are.
The weak-tight guy doesn't think he's weak tight. He thinks he's just smart enough to wait for the best hands and is sure get his money in the best spots.
The tiltmonkey doesn't think he's a tiltmonkey. He just thinks he is aggressive, and that aggression is a necessary skill to win in poker.
The inconsistent/weird player doesn't think he's making a lot of inexplicably dumb moves. He thinks he's being unpredictable and hard to read.
Now the software is going to label everyone:
"You're too tight, so we're making you a sleepy guy! See that, everyone! This guy is so tight that he must be sleeping! LOL!!!"
"You're playing like a tilting head case, so we're giving you a screaming lady avatar! Get it, guys? He's playing like a woman on her period! ROFL!!!!"
"You're playing like a weirdo with inconsistent, suboptimal moves! So guess what? We're going to make it look like you're drunk and/or ******ed. Isn't that hilarious? This player is a ******! AHAHAHAHA!!"
This is an absolutely dreadful idea.
The site should NOT be auto-labeling players with its opinion of their playstyle.
I've played with so many people -- mostly recs -- who were COMPLETELY UNAWARE that their playstyle was unusual/bad/different.
These avatars are basically playstyle-shaming. If you don't play well, everyone will see it in your avatar.
Ugh.
