I give you very easy strategy which work up to $7.5. 2-3% ROI is achievable very easily. Its tested 1 month ago on player, who didnt play poker before (only some MTT-s etc). Started $3.5 and now playing $15.
open 100% of buttons
cbet 100% of the time
if you are not ready to put stacks in, then cbet t30 on 10/20 level, t45 on 15/30 level and t60 on 20/40 level
if you are willing to go all-in bet half pot (or more) every street
give up turn, if you are bluff cbet on the flop (t30, t45, t60). bet if you improved TP or better
check back draws on the turn
if hand is checked to the river, and you got strong holding (2pair plus) bet very big, close to pot
OOP flat a lot
check-fold OOP a lot, check-raise TP+, check-call middle pairs, give up for later agression
check-call OESD, FD without overs/combo draws
check-shove flop any OESD/FD with overs or combodraws
check-shove TP type hands, if draws on the board
3bet only for value. always all-in. exceptions QQ+. then 3bet to t90 at 10/20 level, later just shove
do not run big bluffs
do not make herocalls
do not try to read opponents hand
do not punish their limps without hands. punish when your both cards higher than 8
switch to nash 8bb or lower, othwerise minraise
At the same time watch mersennary old videos. ROFL strategy etc. You can show insane volume, and you can move up every month. If you reach $15, then go for advanced videos. I do not recommend to watch advanced videos yet because it will lead some spew. You need and can establish good fundament, called ABC poker at low-stakes. After that you start building your game, and you see the first thinking players $15, but still quite rare.
Also do not worry about adjusting and balancing lower stakes. Playerpool is too large, and you probably move up very fast. So, you cant see most of players never.
