Good points, but what separates big stake poker players from amateurs, is the bluff. Can't do that trading. Unless you're an adviser, promoter, or selling a service.
Exactly. Pros, push the game. The don’t check or call. They tend to bet, raise, Re- raise or just fold. For the most part, I’m not saying always. Also, you might play a tourney much different than cash. You would never fold a premium starting hand in cash unless you are shitting in your pants and need to go. Whereas in a tourney you may fold if your stack is big enough above the 2nd player ,,,etc.
