Stumbled on a pretty info-graphic on red chip poker regarding preflop ranges. It seems to do a nice job of summing up some of the spots easilly with both tight/loose approaches to the game- This post however was made in 2016 and just curious on what you all think of the relevance in today's games?

Cheers!
