I risk according to value.
which is one of the reasons that I rarely take even a -140 baseball favorite.
I dont risk "to win" on favorites (betting 1.5% to win 1% on a -150 favorite)
If I like a +210 dog, I dont go small because they are a dog. If I feel the line should be +150 then that may warrant a baseball wager of at least .6% (.4% on ML and .2% on -1.5).
If I see a baseball team at -110 and I feel they should be -145 then I'll wager an amount on the favorite according to how much I feel the line is off (it's not usually off as much on the favorite side, IMO, due to parlays etc).
If you are going to flat bet, which I recommend, especially if you are going to choose a relatively small number of games, then wager the same 1% on favorites as you do on +180 dogs. This does two things. 1. it maximizes your profitability and 2. makes those overvalued favorites a lot less attractive.
A -300 favorite does me little good, even if I have it at -400. It's just my way of doing things. If I see 3 large favorites that I feel have a greater chance of winning than what a 3 team parlay pays off than I'll use a 3teamer. I am up a little on 3teamers, but it almost takes a miracle each time for them to come in. I'll never forget Mr Rhodes for that SD comeback in Seattle, but parlays can be useful in minimizing exposure. I use two team parlays a little in football and basketball when I really like the side and total of one game, but they are correlated enough to where if one thing doesnt happen then they both lose, in other words a split is fairly unlikely. It gets tricky not tripping over your own feet with wagers that are correlated to one team having to perform well that day.
It really all boils down to how you do in each situation- on dogs and on favorites. Some people are good at picking their spots with large favorites, others avoid them. Keep accurate records of how you do on favorites and dogs for each price level, you will probably find that your underdog portfolio generates more profit.
I suggest to flat bet if you are going to wager on say 1-5 games a day. With that number of games you are subconsciously looking at a certain criteria for games to fall under, and the value that you are eyeballing on all of your selected games may be close to the same, so flat betting is the way to go. I practice a very strange type of flat betting, even I havent really figured it totally out yet. I have certain tiers of value that games fall under. For baseball, the vast majority of games I wager a total of .5 or .6% on. I subtract or add .1's depending on outside factors, including my degree of certainty and if the team is DET I dont feel like risking the same amount as I would say BAL with Ponson at home.
I have upper tiers games that in baseball may total 1.5%, and these are rare, but have been very good to me so far- I expect a few of these to lose soon.
The rest are nominal wagers. On a lot of games there is information that seems very confusing and doesnt paint a very clear picture. On these games I'll risk .3% or less, sometimes .4% if I have a bunch of these nominal wagers and want to value them a bit on a day when I dont see a whole lot of value. On these nominal wagers a lot of times I'll base the play solely on what I feel is a bookmaker's opinion, or a runline that I think is 20 cents off. They are almost always +EV, I dont make plays in which I dont see at least some value. An example from today was CIN -1.5 +168. I had no opinion on CIN or MIL on the ML. I decided to look at the ML for a quick glance and at +168 I saw quite a bit of value, since CIN had been scoring quite a bit even while losing. MIL is a decent road team and the pitching matchup was a little mysterious so why risk too much? I guess what I'm trying to say is that I bet pretty much the same amount on a lot of games, but I do have games that I feel offer a LOT of value and wager higher but these are relatively few, and the nominal wagers are games that I would have passed on. The nominal wagers add profit, if they didnt then I would pass. If the nominal wagers have higher yield then I try to pinpoint what is going right and up the wager size on those (it is hard to pinpoint). One of the 'problems' that I'm having right now is that my nominal wagers are so numerous and doing so well. If I had been flat betting 1% on EVERYTHING I would be much better off. But it's difficult to increase wager size significantly all of a sudden b/c then you risk becoming over-exposed in the short term when compared to your previous technique. This can really screw with your head, and that is one of the things that I try to control, it's hard to remain even-keel 364 days a year. One of the hardest things for me is to look at games after having a really bad day. But the longer that you stay away, the longer that the defeat stays with you. Then you start to wonder. Once you get away from looking at this in the day-to-day, you can really do better. I actually HATE having REALLY good days, I know from the past that more times than not those days are followed by a
, not that I like losing days either. I look at this market by season. I set goals for what % I want to acquire in each sport by season and chart the progress not so much weekly as monthly. If I get far ahead of where I want to be during a season, I usually cut back wager size a bit, it depends a lot on how much value I see. Typically I start VERY fast early in a season, and that helps, it's much easier to work with positive leverage for a season than to try to dig out of a vig hole. But when I hit losing skids I try my best to look at the big picture and realize that this will always happen at some point, and usually in a couple of days I'm better off than I was before in the BR department. During the playoffs is when the real fun is, I usually wager more on these games as a percentage of what I've made through the season.
