    Question about betting line odds of 1.85/-118
    Hello, first time posting but have learned much browsing through some of these forums.

    I live in Korea and there are thousands of Korean betting sites that are ghetto and have terrible odds. They generally set their line at odds of 1.85 both ways for NBA spreads and totals, which is about -117 or -118 in American odds...Some have odds of 1.86 or even 1.88 but most 1.85.

    Now they usually never change their lines except when there is a big line movement on offshore sites and that also usually takes several hours.

    For example, a few days ago, they opened the Memphis O/U line at 200, and while the line had already jumped to 203.5 on most offshore sites, they kept the line at 200.5 for almost 3 hours before they finally changed it to the correct line. Same with the Houston O/U line, which they opened at 202.5 and finally changed to 204.5, several hours after the line had already jumped to 206 on most offshore sites.

    Of course, I bet the over on those two games and won, but this kind of big point differential doesn't usually occur often. It's usually maybe a 1-1.5, maybe 2 point differential for totals and maybe a half point or 1 for the spread.

    So my question is, do you think it is profitable in the long run to bet at odds of 1.85 or -118 if there is about a 1-2 point differential between the Korean sites and the closing line at offshore sites for totals? What if there is a half-point to 1 point differential on the point spread? I've had fairly good results but not enough of a sample size to determine whether this is profitable over the long run and I do know that at odds of 1.85, I would have to hit 54.05% to break-even. And of course I have to worry that the sites will catch on to the fact that I'm consistently betting into stale lines if this turns out to be profitable in the long run. Korean sites are notorious for what is known as the "Muk-tee" which literally means "eat and run."

    Any thoughts or opinions would be appreciated.

    The half point calculator on this site can be very helpful. It shows that for NBA total -118, it is positive if local line is 2 or more points better than market line.

      Yeah, I've been using the half-point calculator and the odds converter frequently...That guy Granchrow is a genius (I think he's the guy who made the calculator right?) although I don't understand 3/4 of his posts with all those crazy numbers and calculations...but he helped me a lot in introducing me to the Kelly betting system...The thing I find though is that with a 1-1.5 point difference in totals, that's not that much of an edge betting at odds of 1.85...so I guess I would always have to find a 2-point differential or moreto achieve a postive edge betting at odds of 1.85, which is very difficult to say the least......unless that is I can predict winners at over 55% over the long haul...anyway thanks for the reply..

      I guess this is something I'll have to figure out on my own...

        Well if you use the half point calculator correctly you should know when there is an edge and when the juice covers the number. You do not have to figure this out on your own.

          2 point is minimum if you use the generic market -110/-110 line. But if you use Pinnacle line as reference since it is sharper and can also be shaded to one way, sometimes 1.5 or even 1 point difference is enough.

            Ok so I see the Goldenstate line at 215.5 on my site now at odds of 1.85 (-118) and the pinnacle line of 215.5 at -123/+108...because there is a 5 cent differential, do I still have an edge? or would I have to minus the juice and then determine my edge?? Thanks for helping

              On the half-point calculator, enter total 215.5, over price -123, under +108, hit calculate. Then enter -118 on the cell for over 215.5. If the result at right is a positive percentage, it is good. Otherwise, probably not. You can check over 215 too, and it is good.

                  Now you need start to think about how to avoid being stiffed by the "eat and run". Enjoy
