So I looked at a few books for next weeks games (10/5) and BJ and Pinnicle had lines up already... but the speads and o/u were the same except for one game... the only difference was that Pinny had diff/lower juice, but I can't bet there.
So I looked at the bets at BJ, entered my bets for games that I liked... then I stopped.
Early lines may be sharp, but not having compared to other book is sqare, even though I am looking at early lines, b/c I have no idea if I am getting a great line...
Was it smart to hold off, since I don't handicap, and its too early to shop lines b/c most have not posted next weeks lines yet?
well... I don't have the answers to your specific questions, but I do have some side comments that you might find interesting.
For better or worse, I'm going with
The Wisdom of Crowds argument as the term of use from a book written on the topic. Basically, line shopping and betting opening lines is good due to the Wisdom of Crowds. In any market where you have a diverse group of independent thinkers with various levels of expertise, the closing price is going to be the best single estimate of the underlying value. Basically, the spread at closing is almost always the 'correct' line based on all available information. This is why many sports bettors write parsing programs that grab the closing price at pinnacle and compare what they bet verse that line to come up with theoretical edge. You'll see it implied from many of Thremp's posts that beating that closing price is the golden goose. This is also why line shopping matters. The more edge you can get on that closing price, the better off you are. The bid-ask spreads are so small and there are enough markets that you should rarely be very negative in the theoretical edge. Now, this also shows why some sharps consistently beat openers. Openers come before the crowd has had a chance to bring all relevant information to bear. Some guys, well, a very, very tiny minority, are better at predicting where the crowd will end up in select instances than the guys that set the line. Notice that these are usually guys who put in a ton of work and they are picking off 10 to 20% of the lines as being 'off.' Third, there are many guys betting derivatives due to the relations found in the major markets. argh... my grammar sucks in that past sentence. So, the spread is the biggest market for most sports. It's the area where the 'crowd' is most likely to be correct. However, there are other markets, such as moneylines, halves, etc, that should have some relation to the spread. But, those markets are thinly traded and don't have a crowd. You can often pick off derivatives of the spreads. Fourth, there are still some betting markets without a crowd whereby great statistical work or expert toutaments will give an edge (such as MEAC NCAAB games or Turkish bball league). Fifth, there are areas where the crowd fails. Sometimes, they have a systematic bias. You can think of it as a stock market bubble. But, it can be that and much more. You should think about why the crowd is right and then look for instances were the requirements of the crowd fall apart. Ironically, this sometimes leads to edges in the most traded events (like college bowl games).
Now, piss off... I'm done helping all you n00bz
