interesting idea, i like it.

Anyone who hasn't done their own range work should go through Robb's approach or sit down and figure out an approach of their own.
If you haven't studied ranges already then this is way more long term +++EV than another one hour session grinding $5nl...

when i first started to trying out what the various percentages meant, the first step was to know % for any pocket pair, any suited combo, any non-suited combo and any combo irrespective of suitedness. The 4 corner-stones of RANGes 101.

I still play around with this, some sample blocks (chunks in Robb-parlance )

AK/QQ+
77-JJ
22-66
broadways
SCs
SGs
Axs
etc, depends what i'm doing it for.
