Where do you play?3.5 to 4.5
It depends on the number and quality of my opponents. Some people like to bet larger in the button as you are making a larger pot when you have position on the table having shown strength. I do not let my cards affect my bet size to prevent opponents from getting a read.
I don't have a "default" anything when it comes to bet sizing. I change the bet size depending on the situation, what I'm trying to accomplish, the other players, etc., including how to play on the button.
I think that once you get predictable the other players get an edge on you.
Good luck.
Depends on stakes, depends on players in the blinds, depends on type of poker game, depends on image, depends on how the table is playing, depends on...
