-as a tool for psychological influence
let me explain with an example from online poker - being a true pro, and believing that there are no small details - a regular player, based on the geographical, racial, age (and other) characteristics of the table, can change their avatar (AVU) (... an avatar with the image of a 3-4 year old crying baby, pathetically covering their hands from your AA will be more effective in a table with a predominantly female and/or parental composition; a semi-erotic avatar, ready to embrace two brutal KKs, will be more effective in another table) - again, depending on what emotions the avatar is intended to evoke on average - it depends on whether it is considered beneficial to anger this table, to evoke pity, to amuse, etc...
I just like looking at her.
Look at him, spreading out with his KK here...
