Grandmaster. I think that is WAY too large of a variance way.

Most experienced players bet 1-3% of their bankrolls at any one time. Sportsbetting is like poker: variance can be a BITCH.

I've also heard of a "kelly system", in which you bet a constantly adjusted percentage of your bankroll, which has some interesting bits to it.

However, I've been told numerous times to just flat bet a certain amount (2%) of my starting bankroll until I double my bankroll, and then think about readjusting my bet size.

Like Poker, Sportsbetting is supposed to be all about money managment.

When I proposed flat betting 10% of my initial bankroll a game to some of the more experienced bettors that I've dealt with, they said that was a sure way to ruin. Now, a 10% kelly betting strategy is another strategy, but yeah.
