Play very, very tight in the early and middle stage. Use only monster hands to be involved. If you can, see cheap the flop with 1BB limp or wait for Blinds position to call max 2BB raise with suited connectors. Watch for the maniacs on the table and try to figure out a strategy against the other players when they left 3-4. Pay attention if they are ultra passive and when the blinds go to a levels + 100/200 you may try to steal.
Those are the basics, but as mentioned above, you've got huge resources to learn from if you want to dominate.
Something else. On the lowes buy ins at Poker stars 0.50, 1.50 you may find some random players, who are not paying attention to that rules so you may hit them early to double up.
