Bankroll management in sit and go poker tournaments

Artikel i vetenskaplig tidskrift, 2016

This study focuses on Sit and go poker tournaments, where a player with an advantage over her opponents needs to manage her bankroll properly. The study applies the Kelly criterion to games that have several outcomes, where the organizer charges a rake. The premise is that an advantage itself is not enough for a poker player to play at any stakes, because risking too large a fraction of the bankroll will result in a negative expected growth rate, even though the game itself is characterized by a positive expected value. Accordingly, this study uses a formula-based approach to address the challenge of identifying games where the player’s current bankroll has the highest expected growth rate, while also considering differences in the rake.
