Without specific examples, all I can do is give you my basic game plan. This is what works for me. Some people on here will suggest a tighter strategy. I play this way because I find that I can get my very big hands paid off, and I can win a lot of 8-15bb pots with air. Use your own pre flop standards, but I will show my standard for online play. That said I believe in being VERY AGGRESSIVE with a big hand or big draw, and REASONABLY AGGRESSIVE with fairly strong hands like top pair top kicker. I only slow play hands that are so big I cannot imagine someone calling.
I am raising 3bb 100% of the time when I open the pot.
In any position I will open any pocket pair, AK & AQs
--If the table is tight I also open JTs+ from any position.
----if any hand below QQ gets 3bet I am usually going to fold unless the raiser ----has loose 3bet patterns or the stacks are very deep.
From middle position I will also open any suited A, or Broadway hands, suited connectors, and 1 gappers.
From late position I am opening suited 2 gappers, A7+, K8s+
I only call raises with good implied
odds, and position.(the exception being in defense of my big blind) I like any pair, and if there are at least 2 players in the pot I will play suited connectors, including up to 2 gappers, & suited Aces if I expect the pot will not be raised after I put money in. I also like to 3bet these hands occasionally, but that may not be right for you.
If I bet pre flop I am c-betting every flop with 1 or 2 opponents (2/3-3/4 pot, and occasionally pot). If there are more players, I need a draw, or top pair to bet. ***key point*** BET THE STRONG HANDS. This is where I get paid. If I raise 55 and the flop comes AT5, I can usually stack hands like AK on the flop. The same is true for flops like 67A with suited connectors or small pairs.
(it is ok to check raise the flop occasionally if it comes A high and you flop a set, people like to stack off with to pair)
Clearly if you get raised and have a marginal or weak hand, it is a fold.
I like to maintain my aggression on the turn with top pair or better, if my draw comes in, or if my opponent is a folder. I will check to callers if I have a weak hand.
The river is pretty much the same as the turn, I am rarely putting money without a likely winner.
I find that when people do not respect my raises, they are more likely to pay me off.
3&4 betting is something I would suggest you save for big hands until you are beating the cash games already.
I like to occasionally do a dead money grab from around the button or the blinds. When I do it is with one of the speculative hands I would open a pot with air a very big hand that I would have value raised with anyway.
I also suggest getting a HUD and using it to find the idiots. When you can effectively identify & exploit them, your win rate will go up.
*A side note. In a vacuum 22-55, & JTs - AJs are losers in the early positions. Many solid players limp or fold them there. I play them because it creates doubt about what I may be raising with. Showing up with a surprise hand that is near the nuts is how I win most of the big pots I play.
This strategy usually has me voluntarily putting money in the pot around 16-18% and raising around 10-12% pre flop. (the calls usually in position with a small pair or suited connector) It is fairly loose for online full ring games, but not so loose that I bleed chips when I am missing flops. It also relies on reading hands fairly well on the flop and turn. If you have trouble figuring where you are at by that point, just give up on the hand, you're likely beat.
