Theory question: leading into the pre-flop raiser

[Asgrow13]

So I was talking with one of my friends about ways to open up my game, and we got to talking about leading into pre-flop raisers. This is something I more or less never really do, barring highly exceptional circumstances. I know I find it tough to deal with players who will routinely lead into me when I raise pre-flop... I struggle much more with putting them on a hand. I know that some kids like strassa are capable of leading into pre-flop raisers with all sorts of hands (sets, overs, gutshots, air etc.) and by doing so put a lot of pressure on the original raiser and eventually get them to make big mistakes. I'm basically wondering what sorts of spots people are doing this in, or against what sorts of villians, and if anyone has any advice on how to start integrating this into my game. Thanks.
