3 bet bluff, reraised by a 4 bet rebluff attempt?

Ok, first of've all I'd like to understand this concept of the 3 bet, reraised by a 4 bet bluff attempt?

I was the chuck t's video last night where he kept mentioning a person "constantly betting 3 bets, and how sometimes he'd like to 4 bet bluff that person"? I understand what he's trying to say somewhat, but truely am confused about it!!!

My biggest question is

A) WHAT are the hand requirements to 4 bet bluff?
B) What do u do if the person who u reraised rereraises u making it another reraise attempt against u?
C) How do u chose your mark?
D) At what levels of play are these types of moves aimed for?

and I was also wondering if there's a video available online to view that break down everything for u?

Ty all for your time

A) If you're bluffing there are no hand requirements* You do it with the intention of 4-bet/folding. Make sure you don't commit yourself. The 4-bet doesn't have to be big. Somewhere between 25BB-30BB (assuming 100BB stacks) is a good range.
*it makes sense though to pick hands that can flop big (such as JTs) in case villain flat-calls.

B) Obviously you fold, you're on a bluff. Things are different if you 4-bet light. If you 4-bet let's say TT against a very aggressive opponent, you're just gonna have to call it off.

C) Players who 3-bet/squeeze a lot are the main targets. Their range often can't take the heat of a 4-bet. Note how 4-betting as the initial raiser in a squeeze situation is a VERY powerful move because your opponents usually put you on a monster.

D) Forget about 4-bet bluffing/4-betting light at 50NL and below. I lost a boatload of buyins doing that, and they have KK and AA just about every time. Even the looser players.
At 100NL, I'd still be a bit careful but this is where you can start playing back at people. So my answer would be: 100NL+

ah ic, so these moves aren't meant for players with a low understanding of the game, but for players who can think atleast somewhat on your level in the game?

Yeah, I think thats what it is Naruto. Since 3bets usually mean big hands, I guess better players 3-bet light to steal and/or disguise biggest hands. If he's trying to do it too often you can resteal as 4bets are supposed to be huge. This would all be lost on terrible players, you only want to be one step ahead of your opponents or it might backfire. I haven't learned/practiced any of this yet.
