Hi, I am watching a pro from BR, and he told me to use RFI (Raise First In) by position, which is way better to start, cause you dont need really a lot of hands with a player to have idea how he plays.
RFI for those dont know the stat, says how often the player Raised the action when it come in fold/limp to him.
I use RFI in SB/BB/UTG/MP/Hi Jack/CO/BU
Do you use any other stat so crucial like this one?
