No worries, Iβm happy to help!
A nice, generic build I recommend for new Pig players includes Corrupt Intervention, No Holds Barred (formerly known as Deadlock), No Way Out and any fourth perk of your choice. My usual recommendations for this fourth slot are Enduring, Iβm All Ears, Brutal Strength or Hex: Fortuneβs Fool (formerly known as Hex: Plaything). It lets you focus on chase and stealth while your Reverse Bear Traps and the perks slow the game down.
If you want something I bit more spicy feel free to ask, and let me know which perks you have available if you need alternatives.
As far as placing Reverse Bear Traps goes, it's quite simple. You want to get your Reverse Bear Traps out as quickly as possible. There's only two exceptions when you down someone;
- The Survivor in question is dead on hook.
- There are already two Survivors with a Reverse Bear Trap on, and no generators are about to be done.
The reason for that second one is because The Pig cannot see the auras of her Jigsaw Boxes, and you are not likely to come across people looking for the key to remove their trap. Thus, you will likely lose a lot of pressure during the period the Survivors are removing their RBT and you cannot find anyone.
Hope this helps! 
Iβm always happy to help Pig players out so do feel free to reach out in DMs if you need anything else.
