If you don't have $120 to start play freerolls.
If you got $120-$150 buy Poker Tracker and deposit the rest on a regulated site that let's you play 2nl hopefully there is one for your country and I hope it's
pokerstars. That is the best case. $50 for 2nl isn't ideal for a bankroll but if one can't adjust their schedule for when the freerolls are then it's the best cheapest option. I've done bankroll challenges and usually start with $50 at 2nl so it can be done and you can grow a bankroll that way.
I personally prefer depositing $50 and playing 2nl over freerolls. 2nl cash full-rings tables are easier with way less variance then any MTT's. You could play freerolls all year and never final table or win. After a year playing 2nl depending on volume you could have a few hundred dollars up to maybe 1k and be playing 5nl or 10nl. At worst if you're a winning player you should have a few hundred and be taking shots at 5nl.
If you don't have that much money or a regulated site that has tables as low as 2nl then you need to stick with the freerolls. Save any money you have. Put it in a separate bank account from your everyday used account. Make sure that bank allows
online poker/
gambling deposits. In
canada that's CIBC or BMO. Put a little away every pay month/paycheque into that account. My 2nd bank account for poker also is for any and all online shopping I do. Nothing I do online has access to the bank account my pay cheque gets deposited into. Also I never keep a lot of money in the account I use for only poker/online things just in case. Money stays in that account only mins before it's used. Be smart and you'll never lose huge money or any money to scams or hackers if they manage to get in.
Take this sites 30 day course. Don't bother buying any courses/books at this point. There is plenty enough
free poker knowledge on the internet that is good enough to have you beating micro/low stakes. Just use google.
Study Study Study. Learn by starting to play a Tight Aggressive(TAG) style. Also get yourself some preflop charts and start using and studying them. Learn the ranges for a TAG style from early position(EP), middle position(MP) and late position(LP). You also wanna study blind ranges and blind defense ranges.
Don't play over villains or your player pools head. Don't over think it or make it complicated. Don't play with a scalpel when a hammer is the right tool. Majority of these guys aren't big thinkers. Playing over there heads will cost you money hand over fist.
At micro/low stakes
bluff less. When you bet and don't be afraid to bet big/huge when you got pretty near the nuts or have the nuts. A lot of these don't care or even pay attention to the bet size. They'll call anything if they like their cards. I've seen guys call an all-in for a pot of mere pennies plenty of times with mid pair when it was obvious they were destroyed. That's losing an all-in and most times an extra $1.80+ for no reason.
Sorry for the novel hope that all makes sense and helps you some. It should more then get you started on the right path. Best of luck at the tables.
Cheers!!!
