1. You should be betting whatever line whose true probability (whether determined by the market price preferably or your own model in which the market should eventually moves towards) differs from the offered line enough to make it profitable I.E. beating the no vig line. This stands true for the large markets.

2. See point 1.

3. Small markets,props, correlated parlays/teasers, standard teasers,derivatives,pleasers and some alternate lines are precisely what small bettors should be playing since they aren't efficient. Even line shopping between sites can offer value if you know absolutely zero about calculating the true line of the prop.

4. See point #1.

5. BRM is for people with a positive expectation on their bets. I always am dumbfounded but the sheer number of posts on BRM from losing players. It doesn't matter what system you use if you don't have an edge. Everyone else should use a fractional system given personal risk tolerance.
