In part 1 of this series, I spoke at length about the importance of self-analysis. It is not just important though, it is essential if you want be profitable and continue to improve as a player. One of the aspects I covered related to analyzing your previous results and understanding exactly where you were successful, and what you needed to do to improve in the areas where you were not profitable. Game selection is essentially a function of this research and analysis, and should dictate where you are dedicating most of your bankroll. In that respect, bankroll management and game selection go hand-in-hand, and along with self-analysis and lineup construction, should form the pillars of your DFS foundation.
At its most basic, game selection should be the voice in your head saying "What are the games I profit from most often, with the highest upside and the lowest buy-in?" If you stick to that line of thinking, you will most likely find that you are not competing in the GPP's with the biggest prize pools, but on the flipside, you will also not be competing against 500,000 other players. The key is to find your sweet spot with respect to buy-in, prize pool and player pool. This doesn't mean you have to fade the Sunday Million or Millionaire Maker, it just means you should be dedicating more of your bankroll to games you know you can beat. You gain that specific knowledge by self-analysis, so you can see how all of these disciplines are interrelated and affect one another.
