True, but equity can still be a helpful reference pre flop,
"Because many players will c-bet many flops, you pretty much are forced to play x/call, x/decide or develop a balanced leading or /xraising strat"
ofc, this is the essence of OOP poker, and its not enough to accept/vito a hand due to position because of this, are you just saying that the EV of QJo is related to your whole range? if so i
agree

ehm hand history has you in the cutoff? which position are you in?

well, if you fold QJo that implies button can open any 2 cards due to his insane fold equity, do you want that to happen?
QJo has 53% equity against 70% open, youre getting 2/6.5 = 31% equity needed
hence you would have to play QJo terribly postflop for it not to be profitable.
Don't mean to offend but your post seems rather lazy imo, try to really think for yourself as you will benefit more from that compared to receiving other lazy forum responses.

check flop, easy fold on turn as played.

Think about your perceived range and how strong you are on that flop most of the time. Also surely no one tries to rep quads since its literally 1 combo, can he have any 3x here? i doubt it even in a live game

The only way this not a fold on turn is if villains "spazz factor" is super high right?
