I see you are silver status now so your StrategyPoints are definitely going through!
Congratulations, this opens up a lot of new material to you! A move to 4NL is not a good idea even if you did manage to book a win. You are asking for serious trouble! Did you read about Bankroll Management anywhere on our site?
You should definitely stick with NL2 for now as there is a lot less risk of going bust than their would be at NL4!
Variance is HUGE in poker and if you under estimate it then you will definitely go broke!
Any thoughts on starting that blog? This thread is beginning to read like one now ♦
