time the game was announced to the time you bet it (unless you bet it early). paying attention to line moves is important. think of it as shopping. if you are betting on the favorite, you want the line to go down. if you are betting on the dog, you want it to go up.
if are going to bet the favorite and notice that the line is ticking down (ie opened at 8 and is now 7.5), waiting might be the best option. it might be possible, depending on action, to get your favorite with less points given up. it’s also possible to wait too long and lose points. sports
