Do these opening ranges seem decent for NL2 6max? They are for UTG, HJ, CO and BTN. My sizings are 3x for UTG and HJ. 2.5x for CO. And 2x for BTN. Of course there are dynamic ranges that I use as well based on other factors that I read in Grinder's manual, but for now I am just posting my default ranges for when there isn't any data on opponents. What do you think about my ranges? What changes should I make?

I created looser ranges from what Grinder's manual suggests, since I already have some experience. I won for about 8bb at NL2 at about 70-80k hands in 2019, but stopped playing since then. The book says that the more experienced players can use looser ranges.

Also, what range should I open for the SB? I know that it depends based on who the villain in the BB is. However, if we villain is unknown, what should our default range be?
