Bet size adjustment question
hey guys, i'm sure this question has been asked a bunch before but i just spent a half hour searching the forums and couldn't find what i'm looking for. my question is what is the ideal bet size strategy for a 57% winner. should you start with a certain size bet and stay at that betting size (say $100 a game) or, what seems more intuitive to me, should you pick a percentage of your bankroll (say 2%) and always bet that percentage meaning your betting size will fluctuate with your bankroll? if so, what would be the ideal percentage for a 57% winner...thanks for your time!
