1st consideration: your opponent's image. Is he a donk or reg-ish? what are his usual open raise sizings? A donk could be open raising 3.5x with Axs or KJo type of hand. Donks can do pretty much everything. A more experienced player would probably use either that kind of betting to protect his equity (on 77-JJ type of hands), or raising for value (QQ+, AQ, AK). You should just take notes on every player on how they size their bettings and raises when they're betting for value, for protection or for bluff, specially regulars.
2nd consideration: stack sizes. Depending on stack sizes, he could just be bullying smaller stacks. Also stack sizes will tell you if set mining is a profitable option. The call 20 rule above mentioned means that: you only call small-mid pairs with the intention of set mining if both you and your opponents have 20 times the value of the original raise. Which means that under that value, the set mining is unprofitable. But on sit and gos, specially fast, people apply the call 15 (call if you and your opponent have 15x the value of the original raise).
3rd consideration: position on the table. Is the raise coming from early position? Mid? Late? BU? You could arguably 3-bet or even shove (under 20 BB) these types of bets coming from the CO or BU, not so much coming from UTG. Golden rule: only play 88-TT post flop out of position if you are 100% certain you have a serious skill edge to take it post flop. Otherwise, set mining if the stacks are deep enough, or shove if you are short stacked.
