You might be right on hand 1. He either has a monster or a hand that he wants to take to a cheap showdown, If im him I actually might play A10 or A9 like this, obvioulsy the second one has you crushed. AA, KK, JJ all check the river behind and probably call you after playing this way, overall saving you money (although I doubt JJ just calls all the way down). The question is, what could he bluff with, and how much do hands that have you beat bet. Isn't JQ a real possibility here?

Hand 2: I would wait to raise for a better hand than Q7o. You know he's calling with anything so you better raise for value, and this is almost exactly EV neutral against a random hand. Against an aggro player out of position I want to keep the pot small.
