hand 1: I raise the flop. If you make it to the turn and he jams like that then tough spot and i can make argument for both call and jam depending on what fold equity you think you have
hand 2: fine
hand 3: i check-call the turn also. KK/QQ are played too often so you can easily be behind, and if he has KQ, AJT you want him in and betting/bluffing.
hand 4: I either check-call the turn or bet then call his raise, probably check-call since he'll have a wider range of hands that could bet when behind. But I don't like betting then folding if you're up against a LAG.
