I suspect Zen King's expenses take up a large percentage of his winnings. Subsequently, when he comes up against some negative variance it all becomes a double whammy. I cannot imagine how difficult it would be while playing under that scenario. Basically, I live two lives. In the real world, I live in a modest 5 room ranch home and live well but would seem concerative to some people. In the casino, I play the best game available which for the majority of the time is in high-limit rooms. The swings are big like a recent visit where I lost $9500 and won it all back the next day plus a small $900 profit. Understanding the variance involved as well as being properly bankrolled is a necessity because being good in itself is not enough.
