You can flat-call and check raise a continuation bet. You will usually take down the flop if you are timing this correctly. You end up taking the pre-flop bet and the continuation bet. I do not think it is as important to take immediate pots in HUSNGs. It is better to take a chance at a flop and take large bites out of your opponent's stack.

Some people prefer to grind their opponents down. I don't know how these players play.

There are many many lines you can take, but this is so incredibly opponent dependent that there is not single way to play OOP in the early stages.
