ya titling them bot isn't enough there names shall be different and teach em english
Maybe names such as John, Timm, Robert, Alex with no profile pick or account to make it obvious that they are bots. They will all say good luck, and say things like "darn when they lose a piece." One of them analysis the game for you?

Okay man back to the topic. We want bots for 4player chess! lol No theory. That's old school and alpha zero defeated it. Creativity will dominate 4 player chess, cheers!
