> but it's only been written down and analyzed in the last 10 years or so I agree with you overall points. For historical reference for folks who are interested in the poker boom of the 00s but were not there, it’s more like 20 years, if not more. The book Let There Be Range was published in 2008. High stakes players were discussing the issues covered in that book amongst ourselves (live and online) with quite a bit of sophistication for several years before that. All that said, and supporting the point made above, advanced computational support for ranges (esp. via “solvers”) didn’t really start becoming a thing until the early 2010s.
