"Most of us young kids who play [online poker] at nosebleed stakes don’t really have any clear idea about the actual value of the money we win or lose,” Cates says. “Most of us see the money more as a points system. And because we’re all competitive, we want to have the highest score. But really, we don’t know what making $400,000 or losing $800,000 means, because we don’t have families or whatever. This blind spot gives us the freedom to always make the right move, regardless of the amount at stake, because our judgment isn’t clouded by any possible ramifications."
