I am a backgammon newbie and I played games with Snowie 4 for about a month and I followed Robertie's rule to keep under control my progresses looking at the rate of errors after analyzing each game (the one you find when you click on statistics after the game analysys)

I played 10 cash game (cube included obv) every day for 10 days (total 100 games tracked) with snowie at max level registering my error rate every time and I calculated the mean.

On average my error rate is about 11-12, and I don't know if this is a normal or bad result given the fact that I learned the game one month and a half ago. And now I am asking you some questions:

1) I noticed that there are more or less 3 different kind of errors: certain that are A) something like 1.3 or 2.3 that I realyzed that they are huge blunders and some errors that are B) 0.5 0.7 or something that are less important errors, and finally errors that are C) about 0.08 or 0.06 that are small errors.

Can you explain me if the errors of cathegoy C (thouse in the range 0.01<x<0.09) are somewhat a kind of nuances for expert only?

Can you explain me if the errors of cathegory B (thouse in the range 0.1<X<0.9) are serious errors or not for a good intermediate?

2) Can I become a good player if I do not commit errors on cathegory A but only few errors of cath B? What is an error rate for a "good" player BUT NOT a world class player?

Thank a lot

I'll take a stab at the various questions here.

Your error rate of 11-12 is outstanding for someone playing only a month or so. I shudder to think what mine was after the same amount of time.

Error rates for various classes of players on Snowie look approximately like this:

2.5 to 3.5 -- modern world-class, one of top 20 in world.

3.5 to 5.0 -- very good player, most likely has won some tournaments in the open section.

5.0 to 7.0 -- good open division player. Back in the heyday of backgammon (1975-1995) such a player would have been considered world class at the time.

7.0 to 9.0 -- weak open player, good intermediate player in tournaments.

9.0 to 12.0 -- average intermediate player. Probably one of the favorites in the beginner's section.

12.0 to 15.0 -- a player who has read some books and has some experience playing. Will have trouble cashing in an intermediate section.

Above 15.0 -- pretty much a beginner.

You should be working to reduce your average number of errors and blunders over each sample of 100 games. You'll never totally eliminate blunders; there are too many kinds of positions and some are very tough. If you can reduce your blunders to an average number like 3 to 5 in 10 games, you're doing well.
