An area of focus I would feel comfortable in posting will be contrarian plays or strong contrarian radar plays that take the lead early as dogs, only to give up the ass to the better, favored team, late.
Here, we buy the dog pregame, then the favorite if the become a dog or close enough during the game, to gaurantee a profit or take a freeroll position on one side.
There are pitfalls here, but if we are patient enough we can make only +EV plays, or very close to it.
We can also make a list of dog contenders, but not buy them pregame, and just buy the better team once they go down early. This way we don't get messy in selling back +EV, if we can squeeze any EV out to begin with.
