sorry for the dumbness.

When an over under moves to a new number it is -110 both ways.
So when betting with a friend you bet 50/50 making it vig-less.

Is there a standard number to add/sub to a moneyline to make it have no vig?

vig is just on favorite?

Adding to the noobness, is the math just simple enough to do in your head
Ex:
A -170
B + 150

I've been making bets at the poker table with people at 160(for line above). I know it's not linear though and one side has an edge

What is the true line in my example ?

Even if math isn't simple I would imagine the same side (dog or favorite) has the edge every time when meeting in the middle

Appreciate the help, and Im pretty sure this is what OP was getting at

Okay Ty , there has to be a calculator though that would give you the adjusted line

The above gives out percentages and then it's annoying to have to convert back to a line

I just want this info to quickly make bets at the poker table

For example, if the favorite is -300 and the underdog is +220:

the implied probability of the favorite = 75%
75%*(300-220) = 60
300-60 = 240

so the vig-free line is +/-240

Using your example (-170 / +150):

the implied probability of the favorite ~= 63%
63%*(170-150) = 12.6
170 - 12.6 = 157.4

so the vig-free line is +/-157.4

Making the line by meeting in the middle will always favor the underdog.

he converted the favorite's moneyline into a win %. i.e. -300 = 75%.

Use the arb calculator at sbr. Enter dog in line 1, fav line 2. What it tells you to bet is the no-vig line

It doesn't do lines where there's no dog.
