Hello!
As a beginner, I would not suggest playing SSS 6-max immediately due to increased difficulty of the game. Basically, you should just play looser and according to stats/reads. As for SHC, you could start off by removing UTG+1, UTG+2 and MP1 from the SHC, but you really should learn to determine your equity vs oponnent's ranges, along with implementing steals and resteals in your game. Information about that is in silver+ articles and is more difficult to understand than bronze articles, that's why it is not recommended to play SSS 6-max as a beginner.
