1. Too aggressive here? Only lines that make sense are weaker ace, or two pair or set, think I am facing weaker ace enough here? Seems like shorty does this a lot this weak ace, but I am not too sure. Vill is 30/0 over only 20 hands haven't seen him do anything.

2. I do not really like the way I played this hand all that much, I usually will fold AJs to a 3bet, a lot of hands beat me, but I think any hand that beats me bets the turn... so is river ok? Both vill 70+/10-15 over ~50 hands, both seem to be pretty passive post.
