99- What's your line?

[CamelZoo]

I too play hands lower than a set obviously. However, what if Mr KQs on the button who has you all covered decides to push, seeing 2 limpers and a marginally strong hand, and oPFR calls? Do you fold off a quarter of your stack without a flop? This seems like the weakest idea, even worse than calling all in and taking a flop 3 way with 99. I don't like my chances there, and I don't like my chances after folding 1/4 my stack when I am supposed to be accumulating chips for 1st place.

I think it's a clear fold/all in situation - what makes you say Hero is not ahead, I am curious?
