I'm just trying to understand something. At the low stakes 3bb/100 is a modest achievable winrate. At what point if any does that become unrealistic to achieve?
e.g. someone grinds from 2nl - 5nl - 10nl - 25nl - 50nl - 100nl ....
By the time they continue on and are playing 1knl giving the natural progress through the stakes and increased knowledge should it be relatively easy for them to profit at 3bb/100 playing 1knl? how about 5knl?
Just wondering - does it get to the point where the opponents are so good that it's virtually impossible to profit?
