I was never sure whether one should steal from the button more or the small blind more. It seems that better players suggest stealing from the small blind more because there’s fewer players to act but I was never fully convinced. My thought was that, in a blind vs. blind situation, the big blind was calling a reasonable amount of the time due to having position, so to me it was unclear which spot was more successful at stealing. I decided that the only way to find out for sure was to look at my database and see my steal success at each position.
As the button, my steal success percentage is 57.61%.
As the small blind, my steal success percentage is 60.38%.
Stealing from the small blind has a 2.77% higher chance of succeeding for me than stealing from the button at NL10. At least, it has been.
