OTT: I'd still call a bet. When she doesn't bet, checking back is better because I get a free card and don't pay off to her better Ax hands (if she mistakenly check that)

OTR: I'd call most rivers which don't bring draws. I call because it's less likely that villain has an ace as well and most Ax hands x/c OTF.
