i am making new hand range by using pokersnowie
I quickly noticed that the hand range of pokersnowie is too tight
also, there is many things that i can't understand

lots of people say pokersnowie's preflop chart is pretty decent
is it only for microstake players who are not comfortable with post-flop?

PS. but also there are many things in the chart that i like, such as opening range and cold calling range in position
