JD - this might be a dumb rookie question, but why does BetUS post one line but then jack it up when you sign in? Sometimes it is a 30 cents jump on top of their already awful favorites lines. I thought it was just me, but have talked to others who don't even play baseball there and it has happened to them as well.
not dumb at all. many books, especially all the big public ones (bodog, betus, etc) do what is called a dual line. if they tag you as sharp, betting steam, etc you get profiled. for example, the lines i see at betus are not what most people see. books that do not do dual lines (5dimes), will put people they think are sharper on a delay. so for example, joe public hits submit on a wager and it gets processed that second. someone they have profiled, hits submit and it could be 10, 15, 30+ seconds before it is confirmed. this allows them to make sure there is not a big move on the game. thus the infamous "the line has changed" message.
