I would play it basically the same strategy wise. Limping big hands and then 3betting. However, I would make all raise sizes larger.

I hand 1 I would raise it $100 on top preflop and then bet the flop for like 3/4 pot. As played I think I'd just stick it in since he's calling down all pairs. If he might bluff though but not call with just high card then I probably would check and then call the river shove or put it in yourself.

In hand 2, I would make it $117 total again. You dominate average calling ranges for bad live players vs. a huge fish.

For the third hand I would make it $100 straight preflop and shove the flop. As played shoving the turn looks fine since you'll have the best hand sometimes and the best draw other times.
