The number of players is kind of arbitrary given the techniques we're using. We chose 6 because that's the most popular/common format for poker. I don't think there's any scientific value in also doing 10.

I am obviously a human, not a bot, but in my experience playing poker, it seems much more likely for me to be successful, personally in a 6 player game, whereas a 10 player game, I never seem to do well.
