I am trying to learn HU cash 100bb deep, coming from small husngs
However, on most sites there are only HU tables at 50NL and higher, which would require me to have a bankroll between $3000 and $5000 just for learning heads up cash.
Can I somehow learn the game playing 20NL?
Also, rake for HU tables should be lower than for ring games because we see EVERY flop. But it seems that rake is not lower HU and people playing a 80% range will rake 4x as much as ring game players with a 20% range (on average) because we see flops at a much higher frequency.
Hunl has a lot of preflop play
