Hello!

I have watched a lot of nlhe videos here in RIO, and noticed that different coaches uses different open sizing from button. I would like to hear some toughts why somebody open 3x, 2,5x or 2x, and how different sizing effects general strategy? I have been thinking to change my standard sizing from 2x to 2,5x, because my button winrate doesent satisfy me and that is why I am asking this.
