I like to play suited connectors and gapped cards from 4 on up. So 45s, 46s, 56s, 57s, etc. I'll raise with them sometimes, limp or call raises other times. I think I had a thread on here about it, even. What you're basically hoping is to catch an aggressive player with high cards or an overpair, and flop something nice - two pair, a straight or OESD, a flush or flush draw. If you get two pair you just jam the pot, if you get a draw you proceed accordingly. I don't do as much of what Rippy does (raising/calling down with a low pair) but I have done that before at times when I had a read that told me to.

The reason I play 4 and higher is that your odds of getting a straight increase. 23, 34, 24, that's pretty much crap in my book. Less so if you're approaching it like Rippy does.

This works best against classic mid-level TAgg players who play "by the book," but have the all too common flaw that they can't let their good starting hands go. It also works best if you have good instincts and are willing to listen to them. Finally, it works absolutely the best when your stack and theirs are a lot larger than the pre-flop raise, so that the implied value is there if you hit a really strong hand.
