Frankly, I'm shocked at the content in this thread. I should have asked THIS in my quiz
!
1. Runlines typically suck vs. MLs since most books have dimelines on sides, but 20 cents (or more) on RLS. You can lay -1.5, or take +1.5, either way you get pulverized by the much higher house advantage. NEITHER is a good play most of the time in competively priced games.
2. When the ML goes to -210 or higher, RLS become more of an option. Since most places now price sides with at least 15 cents total vig or more (-220 +205), the RL at least is not blown out of the water in terms of value.
3. Rogue MLS often exist at weak shops that allow sharp bettors to take advantage.
4. RLines offer great correlated parlay bets at select shops for sharp bettors.
5. Pinny has 10 cent RLines vs. 8 cent sides. Obviously, you are going to find some RL plays here that have value.
What is going on here at Rx.com with horrendous posts like "Never lay -1.5 on home teams" or "Always take 1.5 on big dogs, etc!". You would think we all just started betting bases for the first time in our lives. Ideally, you should make up a chart that shows the proper conversion from ML to RL. Obviously the conversion factor is going to be the highest for
1) Home Favs and
2) Low totals.
Having said all this, guys who are far smarter than me have done all this work, and the R/Ls presented typically match the chart for the game perfectly. So it is possible to find a team with a suspect bullpen, etc. where the RL vs. ML conversion from the chart may be off, but it likely is off just a bit.
FINAL CONCLUSION: Generally avoid RLines, but actively look for good rogue RLines on teams you were going to bet, especially in games where no good side Rogue lines are available. And actively shop RLs on huge vig games you are playing (-260, +230). In these game, the RLs offerred for FAV AND DOG typically offer as much value as the sides.
