Many poker websites e.g. this one https://automaticpoker.com/strategy/free-poker-preflop-range-charts-with-printable-pdfs/ have lots of charts that rank the strength of starting hands in Texas Holdem.
Is there any online resource where I can easily create my own custom range charts? Sometimes I disagree with the resources I find, maybe because I'm playing at different sized tables, and maybe I want to create one chart per position (early, middle, late, under the gun, etc.). Also, as I play more I will learn more and I'll want to easily update some values.
I tried searching Google, but the only results were more opinions on starting hand ranges. Has anyone come across such a resource online anywhere? Thanks.
