I am struggling with these situations also, after the first replies suggest to donk this flop, the later ones suggest c/f.

But against a range of the other JJ combo, QQ+, AQ, AK you still have like 50% equity. If you are not planning on betting this flop (hoping to take the pot down), then you aren't basically betting any flop without a J.

I read somewhere else that you need to make about 11.6 times your initial investment to justify calling for setvalue. Since you call the 4bet for $2.5, you need to make $30 dollars on average. I think this unrealistic, so then I should suggest folding to 4bet preflop is better.
