I've long wanted to write a book titled, Nuclear Reactor Design For Dummies,
or perhaps, The Klutz's Guide To Brain Surgery. Wouldn't that be a comforting
sight on your specialist's shelf? Although my plan was to write a humorous book,
some serious observations about playing for money on a site with an Elo rating
system can be applied by backgammon players below the expert level. You don't have
to be a world-class player to win money playing backgammon

I'm perplexed at the low ratings this article has received. Usually, one person gives each of my columns a low rating, but here three people gave this column a low rating.
Upon review, this column still appears to be correct, new, and useful to a wide range of players. Although I didn't provide specific advice on how to play any position, such advice is not supposed to be the focus of my column according to guidelines given to me by GammonVillage. Many players have stated that the rake is unbeatable and that ratings and money play are incompatible. This column contradicts both of these ideas. In match play, the rake is often a small Elo point penalty. I gave a simple strategy for beating the rake, using the rating system, despite the fact that ratings are unreliable. I provided a new accounting system which ignores much of the luck in backgammon if you do not vary the stakes you play.
If you strongly dislike this month's column, please let me know why.

I am a long time casual backgammon player, who just became very serious because my new job requires everyone to learn backgammon. I play on PartyGammon and TMG, and have just begun to see how important the rake and a ratings advantage are to becoming profitable.
Your article will help me tremendously. Thank you so much.

Thanks for the kind words. I'm glad you liked this article.
I'm curious about your job that requires everyone to learn backgammon. Can you tell us more about it?

I like all of your articles. I think I gave this one a "4" just because you've set your own standards so high. For instance your article on the Kelly Criterion applied to backgammon money play was superb.
One thing I found interesting is where you write that the rake on a couple sites was/is unclear. I agree, and if it's unclear to you when you were making a serious effort to understand them for an article, of course it's extremely unclear to someone just making a quick look. Hopefully that will change?!
Your point about money play being harder to include in a chart like the initial one is interesting. For instance, I played a series of nackgammon money games recently on clubgames. I think they use a similar formula to gammonempire for rating money games. I finished ahead 19 points overall, but lost a majority of the games and finished down 1 rating point from where I started. So, what this shows is that the rating system for money games is just not very good. Hopefully that will be improved as well?!
I'm also curious about that job that requires learning to play backgammon...
Hi Douglas,
There is nothing wrong with this article. At the very least, that's a true statement from my perspective. Indeed, I believe it's probably one of the more practical articles you have written, assuming that making money at BG is important to you. Maybe that's the problem, all those interested in making money have gone to poker!
Just curious, how many people voted (in total) to give you a mean of 3.6? When using a scale of 1 to 5 it's hard to get outliers affecting the mean by a significant amount unless your sample size is particularly small.

Thanks for the support.
When I posted the comment about the rating, the average rating was 2.8 after 5 or 6 votes. The number of people who have rated the column is displayed in the archive of columns.
