Hi Guys,

Around the forums and on many of the videos there is a lot of conversation about range construction, however this seems to be focused entirely on narrow postflop spots, (obviously because the analysis is easier) however there isnt much discussion about how to derive a preflop opening  range.

So my question is how would I go about deriving opening ranges, obviously this is much harder than postflop analysis, but any help or pointers in the right direction would be amazing.

Cheers,

Ryan
