The reason why a lot of these situations are hard to assess is that they SHOULD depend on gameflow a lot.

If I'm ramming on someone from the button to their CO opens over and over again... repeatedly and then they 4-bet me and I have 55. There could definitely be times where I shove over with pocket 5's here or something. Because his range can be tons of 4-bet bluffs and also most likely hands like AK/AQ as well.

With regards to 3-betting hands like 99-JJ and stuff. I usually try to avoid making plays where if villain comes back over the top I'm actually confused and don't know what to do. If I am 3-betting 99-JJ against any villain its because I either know that if he 4-bets me I'm folding.. or I know that if he 4-bets me I'm jamming. I don't wanna make a play that puts me into a spot where I don't know what to do.

Whatever you do, you need a plan!
