Welcome to micros forum.
Few points on hand posting etiquettee:
1) results are unimportant, you don't need to show them or even imply as to what the result was. They will bias the opinions of your responders, just as they likely bias your own thinking right after you played it.
2) Properly converted and formatted hands are much nicer to read (and will thus likely get you more responders).
3) Including any stats, reads, or other information about the villains, table dynamics, recent action, etc will help in getting more informed responses. If you're not paying attention to all of these details, well......you should be.
As to the hands (void any information about the villains).....
#1: Raise the turn, call down if 3bet. A sudden turn donk could me so many things (he peeled flop with overs and spiked a pair on turn---what actually happened; he turned 2pair, he's screw-playing a draw, he picked up a draw or additional draw, etc). You apparently put him almost squarely on J9 and very little else to put the brakes on.
#2: His turn play would be a bit spaztastic for KQ, so I'd have trouble putting him on that. And since that is the only
thing you lose to (and there are reduced possibilities of it, too, given you hold one queen), I'd go ahead and 3bet/call that river. If it turns out he did have KQ, well, that's poker. You take a note that he's a bit of a spaz who can WAY hyper-play a draw on the turn HU, and move on.
Edit: Also, +1 million to this:
