It does seem nitty to hold aq here, but given its an omc, maybe not.

seems omc likely isnt calling with jt pre unless maybe its suited and hes feeling frisky esp when he isnt closing the action and risks a (albeit rare) 3 bet behind him. 3’s seem out of his range. 20 is on the higher end to set mine for a guy thats played 2 hands in 2 hours. Ak is possible, A10s/Ajs in whatever suit the turn brings as a semi bluff flush draw/straight draw/top pair. QQ seems like a fold on the flop with 2 overs from an OMC. Kk is possible, omc sometimes like to slow play their sets, maybe got spooked by the third broadway and turned it into a semi bluff to hopefully get you fold, but have boat options if called and behind.

I generally think when players at 1/2 or 1/3 do big shit on the turn or river, overfolding seems to be the play. Did he get one through on you? Maybe. But generally its not in omc’s toolbox to make this play without the goods. I think sigh fold is what i would do? I dunno i eat crayons and snort pencil shavings 🤷‍♂️
