Please bear with me here, as I come to you asking what my next move should be.
I have been playing poker for a couple of months now, playing in a pub poker league and round friends, but mostly online. I have read a few strategy articles and own Dan Harrington on tournament play, but have only really flicked through the books.
I have $20 left in my Full Tilt bankroll after getting up to $50 for a while and losing it. I play a mix of everything, normally losing at cash games (see chart);

I have also been playing Super Turbo SNGs, for which at the start was going well but I have seen massive swings;

So now im down to $20 and dont really want to redeposit, I ask you what my next move should be. I have read that 1 type of game should be my speciality, and I would say prefer SNGs
Should I get some more books, specifically SNG books? If I start on the $1 tables and work at them for a while to get my bankroll up would this be advisable? Study strategy before going back on? Im not sure and would like to hear your opinions.
P.S. I know that Super Turbos aren't really poker, so will play the normal or turbos.
I'd really appreciate anyones help on how to become better, thanks in advance.
