This is an open letter to my friend: please stop going to casinos.

You and I met in a casino about a year ago and developed a friendship. I was impressed because you described yourself as an "advantage player" who took advantage of casino promotions and offers, and you played the right games and made the right bets and you won money. You were reaping in the comps. You were having a good time. We even traveled to Las Vegas together to take advantage of offers there including free rooms and free meals and we even beat a casino in Vegas by teaming up with a doey-don't system at craps which returned a nice profit for us.

But now, I am going to ask you to stop going because it is clear to me that you are no longer having fun, and having fun at casinos is the only thing you can really bank on. No one can bank on winning, and if you're not having fun it is pointless to go.

I should have told you this a couple of weeks ago when you told me you lost your bankroll after some poor sessions at poker and craps and video poker, and it surprised me that a week later you were back at the casino.

But it is clear to me you are not having "fun" anymore.

"Fun" can be defined several ways: Winning is of course a great way to have fun but you haven't been winning. Getting comps that are worth more than your actual losses can also be fun. Going to shows and events can also be fun. Having great dinners can also be fun. But you've told me nothing in the past couple of weeks that indicate you've had any fun at all.

And just tonight you complained that a free shuttle bus was literally three minutes late. Can you possibly be having "fun" if you have to make a big deal over a free shuttle bus being 3 minutes late?

You are no longer winning. Your comps have been reduced. You've had a lot of bad luck. You never said you rebuilt your bankroll. So, my friend, stop going.

The casino is no place for you now. Your "advantage playing" is no longer giving you an advantage. You are not getting the comps you used to get and you are no longer winning.

You described yourself as an expert mathematician who played by the numbers. Now look at the numbers -- because they no longer add up to being positive on the fun meter.
