Playing oop sucks, and playing big pots oop sucks. However, btn in hand1 limped. Thats enough to be confident to bet/fold bet/fold bet/fold for value 3 streets.

What can he have? Never KK+, likely not AQ, and its hard to have 22,33. Q3/Q2 are laughable and you arent screwed against these holdings anyway. However, if he has QJ, QT, Q9 or heart-heart or 45 or something, then you are missing a ton of value by betting as small as you are. Villain limped his button, his hand sucks and hes probably bad and a calling station for doing it. He isnt gonna be tricky and hard to deal with, so just b/f b/f b/f.

I have no idea hand2. Without knowing who he is, i take the 0ev option and fold pre. I can see 3betting and calling depending on his stats though
