JQ is a marginal hand at the best of times utg+1 it's an absolute clear fold for anyone who doesn't have excellent post-flop skills.

You put in a hefty bet on the flop and got called. This is where you think to yourself "maybe TPGK isn't going to be enough", and check/fold or check/call to showdown.

I suspect this hand is only being discussed because the villain chased, and hit, a flush that maybe he shouldn't've. You can expect to beaten by a genuienly better hand in 75% of hands like this - just see it as evidence why QJo is simply not good enough to limp from EP.
