What most players don’t understand is that unless you play a high number of table hours at high limits, you are better off collecting bonuses than sticking at one room on a rake back deal. The bonuses are a higher rate of return than rake back in most cases.
I know a player who has played full time online for over a year and has played for a bonus every single hand. He knows about rake back and is just not interested because he understands the above and makes more in bonuses than he ever would with rake back.
