My advice to small rollers
If you have less $100 and dream big, here is my advice to you:
Dump holdem. Find another form of poker that appeals to you and study it as hard as you did holdem. There are tons of people out there who can play HE, and against someone who knows even basic strategies, a good player's edge is frustratingly small.
But the other forms of poker out there? At the lowest limits, they are incredibly, incredibly soft. There are people who honestly don't know how to play poker, there are people who know how to play holdem and are trying to play the same strategies, and there are people who are just bored and want to try something different. You can skin all of them at the lowest limits. Obviously, as you move up it gets tougher, but at the early stages of bankroll building, this is your best bet I think.
I've gone from grinding out NL10 to just absolutely crushing Razz and PLO8.
It's challenging and fun, and most important profitable.
