ALright guys Ive been playin poker nl and lately limit for about 8 months and not till recently I started winning. I have lost about 1.5k before i learned about proper br and stuff. I currently have 700$ on pp playing 1/2 but Im thinking of putting 600 more to play 2/4. Should I move up to quickly or just let it ride out till i have proper br for 2/4> ? I started with 100 2 weeks ago on pp and got it up to 700. Is it profitable to play on pp even without rakeback or should i put some money elsewhere and take advantage of rakeback?
