Either I'm really bad at this game or the bots are really hard to beat. I have played maybe 20 matches against 3 bots and they beat me by such an unbelievable margin I'm starting to doubt I understand this game.
How are the bots compared to human players?
They are decent for playing "big money" and sometimes do horrible things. In general, they are not very good. You might want to watch this: https://www.youtube.com/watch?v=dXctQJxg524
