Hi, I'd like to understand or find a video that covers / explain more about this (cash zoom 6max 100bb):

If we open a certain range from let's say, HiJack ~20% of hands.

And we face a 3bet, in two scenarios, from Button which leaves us OOP, and from SB which leaves us IP.

By "general knowledge" (from what I read elsewhere), we expect BU IP 3betting range to be wider than SB to OOP 3bet HiJack.
Which % of hands / our range should we defend in these examples ?

I mean, most of the articles - content I've found, advocate for a wide continuing range IP. That "position enough" would be worth the call.
I wonder if this is the reality, because if you are HJ/CO and faces a 3bet from the BB (say around 4.5%-6% range), which range should you call with, even IP how would you continue?

Any enlightening in this matter is highly appreciated !
Bonus question: If you find someone that 3bets 3% only, could/should you fold everything and only 4bet your premiums?
