AcTc v Q2o+ or Q2s+ on board of Qc9c3h

you are a 44 to 56 underdog. If you are sure he has a Q and will not fold to a raise, u should fold,

pushing is better than folding, even if you assume he has a Q and will not fold. the pot is 35k. if he won't fold, it's essentially an 83k push to you. villain is more likely to have AQ than other Q's, so say you're actually a 42-58 dog. that's almost exactly the pot equity you need to make this a breakeven chipEV push (you need 41.2%).

but here's the thing - there's no way his range is that tight. even if it is that tight, there's no way that OP has played enough HU with this guy to know. because things chance HU, and there's some chance villain is leading out with a flush draw, and if you fold then, you're making a bad mistake. you're way overestimating the accuracy with which you can put him on a hand. trust me.

whether calling is better than pushing isn't really clear. if you're pretty confident that he has a Q, it's probably better to call because he'll have to pay you off. if he's so tight that he won't pay you off if the flush gets there, then you should be running him over.
