This is my 2nd year of betting so forgive me if these are stupid questions about runlines but I never really bet them last year. I'm trying to develop a system for baseball using the runline. It's coming along good and I've backtracked 2005-2007 the past 3 days and each year had winning results. I'm just trying to determine to the nearest dollar what my results would have been. I switched from Bodog to BetJamaica this year, I didn't see anywhere on the site that BetJamaica uses runlines, but I assume they do? I simply got fed up with Bodog's Christmas colored boxes and late lines. Plus there's higher limits at BetJamaica. Anyways:
1. Is the 1.5 runline ALWAYS given to the away team or is it given to the underdog?
2. How do you figure the odds of the runline? For example if the favorite/home team is -160, how would you figure out the away/underdog's 1.5 runline is?
3. Does matchbook.com use the alternative runline?

The juice on RLs are set on a case-by-case basis, and they are usually also a function of the total. (i.e., the variance between the odds on the -1.5 and the ML should be greater if the game total is 8 than if the game total is 9.5). If you want a VERY rough estimate for research purposes, move the -1.5 90 cents from ML if the home team is favored and 55 cents if the road team is favored. Again though, it is probably dangerous to use overall averages like that for specific ballparks.
