The Kelly criterion is based on a rock solid mathematical approach and offers several advantages. For those of you who are good at determining odds, it offers a dynamic way to increase profits. However, it is important to understand that this is a pure deployment system. It is incapable of discovering bets with good value on its own and is therefore not an automatic path to success. It all depends on how well you can judge things for yourself. It should therefore be used with caution, especially if you have had little experience with betting.
