Money Line Betting Explained v2.0

(v1.0 located here)

Disclaimer: This is a public service announcement that is applicable for this section only. The content of this post is solely the opinion of the thread creator. D2JSP does not support or endorse betting.

Introduction
    Hi, I'm lncarnaxim and I will be your pilot once again. :D I still continue to see inquiries about sports betting and specifically, money lines. What does it mean when people say 4:1? What does it mean when a fighter is listed as -400? Hopefully these questions will be adequately addressed. This version will not cover point spreads, parlays, or other facets of betting. Perhaps in 3.0. :) I'll give a few examples of money lines and explain them (hopefully accurately). I also have a section for people that want a quick read or merely want to figure out how this applies to you entitled MMA Betting on D2JSP. Thanks to MerleHaggard as usual for his input.
Money Line Examples
    Example 1
      These odds are made-up. For example if the card reads:
      Quote (Made-Up Odds In My Head)
      Anderson Silva (-500)
      Chael Sonnen (+300)

      So if you were betting on Anderson Silva, to make $100 you'd have to put up $500 ($600 total = $500 risked, $100 made if you win the bet). If you put $100 on Chael Sonnen to win, you'd win back $300 ($400 total = $100 risked, $300 made if you win the bet). In this instance, a fair proposition would be to have 4:1 odds on Anderson Silva. So if you and I wanted to bet, I'd put down 400 FG and you'd put down 100 FG. The bet winner takes all 500 FG.

    Example 2
      Another example with actual odds according to betus.com:
      Quote (Actual Odds According to betus.com)
      Junior Dos Santos (-350)
      Roy Nelson (+250)

      In this instance, putting down $350 on Dos Santos will get you $100 back + your original investment ($450 total). Putting $100 down on Nelson will get you $250 back (or $350 total). The actual odds usually depend on the person with whom you set the bet.

    Example 3
      Here's a final example using another real-life example from UFC 118:
      Quote (Actual Odds According to betus.com)
      Kenny Florian (-140)
      Gray Maynard (+110)

      To make $100 on Kenny, you'd have to bet $140. This would get you $240 back ($100 + Original Investment of $140). Maynard is listed as +110, which simply means betting $100 yields $110, sending you home with $210 in your pocket. I think you get this by now.

MMA Betting on D2JSP
    So, here's the way I translate these moneylines to get to those ever-familiar ratios. I merely add both numbers (ignoring the positive and negatives) and divide it by 200. Let's briefly revisit our first three examples.
    Example 1
      Quote (Made-Up Odds In My Head)
      Anderson Silva (-500)
      Chael Sonnen (+300)

      500 + 300 = 800 /200 = 4. So, a betting thread for this fight might have 4:1 odds. Someone would bet 60 FG on Silva and another person would bet 15 FG on Sonnen.

    Example 2
      Quote (Actual Odds According to betus.com)
      Junior Dos Santos (-350)
      Roy Nelson (+250)

      350 + 250 = 600 / 200 = 3. I'd probably put up 60 FG on Dos Santos vs someone else's 20 FG on Nelson.

    Example 3
      Quote (Actual Odds According to betus.com)
      Kenny Florian (-140)
      Gray Maynard (+110)

      140 + 110 = 250 /200 = 1.25. On this particular bet, you'll most likely see 1:1 odds, or you may see 125 FG to someone else's 100 FG. This depends on how the person decides to round it, if at all. :D

Betting Sites
    People use different betting sites to retrieve money lines. I personally use http://betus.com. If the person you're betting with gives odds you don't understand, ask him/her for a source and/or check the betting sites. Most people give sources to their money lines and there are also a lot of helpful people on this forum who typically speak up if someone is not giving reasonable odds (like me B) ). If you dislike the odds, please voice your disagreement politely (as with all disputes in this forum) or simply don't bet. Also, remember that it is common for money lines to change as an event grows nearer, so don't feel cheated if you happen to notice someone with better odds than you. Here are several commonly used betting sites in alphabetical order for your own reference:

Frequently Asked Questions
    What do the "+" and "-" signs mean before the number?
      These signs are not part of the number, but are rather used to denote the underdog and favored fighters. The "-" sign denotes the favored fighter and the "+" sign denoting the underdog. Typically, if each fighter's number is preceeded by the same symbol, this means that the odds are virtually even.
    Why don't I see odds for "Fighter X vs Fighter Y" fight?
      Chances are that it's too far away from the event. Some fight odds aren't listed until shortly before the event, especially undercard fights. Just be patient, it'll be there!
    Why do you divide by 200?
      As explained by our very own MerleHaggard:
      Quote (MerleHaggard @ Jul 10 2010 10:04pm)
      It's to split the difference between the odds of the two fighters.  If fighter A is -350(3.5:1 in favor of fighter A), and fighter B is +300(3:1 in favor of fighter A), it becomes obvious that there is a discrepancy in the odds between the two fighters, meaning that the odds are going to be different depending on what fighter you're betting on.  This is unique to bookies/betting sites, and is how they make their profit as the third party in the bet, but obviously doesn't work when two private parties are betting against eachother,  so to be fair to each bettor the difference is split between the two, and when using money lines, 200 is the magic number that achieves that.

      -350(3.5:1) + +300(3:1) = 650 / 200 = the difference between the two odds, which is 3.25.

      However, if you were to reduce 350 to 3.5, and 300 to 3.0 to begin with, and add them together (6.5), you could then just divide that number by 2, and this would accomplish the same thing, and perhaps be more understandable?
A Final Note
    While this should address a majority of the questions I've received about this subject, this is by no means an all-inclusive guide. If you have any further specific concerns about betting, I can do my best to help you out. Just post or PM me with questions. Chances are, if I can't answer your question, someone else will know the answer, and I'll include it in the next update of this guide. If you have any suggestions as to what can be improved, please let me know as well. Happy (and safe) betting!
