its pretty basic
For my first strat, I look around, and find a target with someone close by. I move away to throw sus, then sab lights. I get the kill to immediately just run off, while the other person gets blamed. Its helped me in 2 games.
My second strat, effective still, but not as much. I wait until there are about 4 players left, me and the other 3. I go into admin, and check the map. If I find two people paired up, I shut the doors on them, making them sus the other person they were with.
