Hand1- Fold flop, his cold call pre and donk for pot into 3 players is really strong.

Hand2- Not bad, although it's pretty close because if he is as passive as you say he's likely very strong when he busts out check raising the river like this. If you give him a range of sets, straights and two-pairs then it's close and you might just call his check raise but if you think he can do this with AK as well then your equity is good.

Hand3- No reads here? I'm folding the flop but I'm not sure about this hand. Depends on the opponent.
