OP, depends on villain to some extent.
Generally just start getting money in the middle as soon as you can. If they fold the flop doesnt mean you played it wrong. If they have an ace they will probably call down, if they have air they are not going to call later on anyway, and you will just miss value by checking.
Just avoid mashing the pot bet button everytime you have the best hand because it will be a huge tell, Mix it up a bit, but generally bet big on each street when you have the goods.
