Preflop
I would not call an EP open with QJo. Just fold and wait for the next hand.
Flop
When the preflop aggressor check, I would also put out a bet here to thin the field, charge draws and even a little bit "for information". If someone puts in a raise, or if you get multible callers, you can usually just shut it down with top pair meh kicker in a multiway pot.
Turn
A donk bet on the turn usually mean, people just improved their hand, or they picked up some kind of new draw. So first off we need to think about, which
hands he might open UTG and then check-call the flop, which now improved. And the obvious candidates for made hands are AK, AJ and KQ. Against that range you are obviously crushed and need to fold, when he bet almost pot.
Now he could have some bluffs as well, and the most likely candidates would be AdTd, Ad6d, QJs, JTs and JJ, since these hands all picked up draws. However they are also pairs, so he might often just go for a check-call again. And even if we give him all these bluffs, you still only have 26%
equity, which mean, you need to have a bit of implied
odds going to the river.
And I think, they are kind of difficult to find here. If he has AJ, and this is perhaps his most likely hand, then an A will chop the pot, and a 9 will give you an expensive second best straight. Half of your improvement cards will also put a flush on the board, which if nothing else will kill action. And he is probably not going to crazy with AK or KQ, if there is a 1-liner on the board either.
In top of all that you are not even closing action, and the guy behind you is sitting on a stack, which is kind of ideal for jamming the turn over a bet and a call. Which is obviously not great for you either, because it will force you to either fold or put more money in, when you are likely behind.
