i was worried about HU play coz the only thing i know is that it's mathematically correct to raise at least 80% in position. But the table fills up very fast.

Watched a few grinderschool vids on it, there's one where spenda and another instructor called sugarnut play HU and they BOTH record the session so you can watch it from each of their perspectives separately.

Goes over my head though... range merging?? still, playing in position is the golden rule so i think that's enough of an advantage to know at these stakes... ?
