Hand 1 - My first impression is that this looks like a huge draw. I would call most of the time here, but if you analyse it maybe I should be thinking about folding. You are either flipping to a big draw like AhKh, or losing badly to a set imo. 89 is also a possibility. JT is kind of a possibility but you say he's not overly aggressive.

Hand 2 - I am still not good enough to fold these, hence I push. I guess hand 1 factors in because if he pushed with a hand in 1, I'd imagine he would have done here.

I'm not comfortable laying down hands like these against aggressive opponents short-handed. I would likely play for my stack in both. Maybe this is a leak. Maybe I have it confused and hand 1 is a no-brainer whereas you should think about folding in 2.

edit - I meant to say in my summary that his range in hand 1 is probably a lot wider than I'm making out. There's no reason he couldn't have AA-TT here either. Boo, I dunno.
