Hello all….I am trying to understand the numbers when analyzing my cube decisions. I understand the “Winning Chances” part but not the “too good, no double, double/take, double/pass” numbers. I am attaching a picture of a cube error I made that I doubled when it was too good. Any help would be greatly appreciated!

Thank You

Those numbers are called equity. To explain it simply:

Double/Pass +1.000 means: If you double your opponent should pass. So you win exactly 1 point.
No Double +1.149 means: If you don't double you win on average 1.149 points (thanks to some gammon probability).

Therefore by doubling you are giving 0.149 points on average away.

(Double/Take +1.732 means: If your opponent is so stupid to take then it would be even better for you.)

Say you were just playing individual money games and you were playing for $1/point, so you win $1 if you win the game with the cube on 1 and winning a gammon would be worth $2.

"No double: 1.149" would mean by not doubling you would win $1.149 on average, say if you played out this position a million times.

"Double take: 1.732" would mean you win $1.732 on average if this position went double and take.

and of course "Double pass: 1.000" means you win $1 if the game goes double/pass.

But this a match, so these "equities" are adjusted for how points are worth different amounts in terms of match winning chances. Winning two points for a gammon, for instance, might be worth more than twice what winning one point is worth. It's fairly complicated how the computer does that, but you can still think of these numbers roughly like "doubling costs between .1 and .2 points, so it's a pretty big error."
