Question about the NL ring strategy

Actually , iv'e not read this article for over a year , i'm pleased you brought it back . It makes more sense to me now. Id say im not qualified to say it needs updating .

And Renton is specific about limping

I typically raise pocket pairs 99 and up. Some people limp 99 and TT under the gun, I don’t.

....If you limp these hands you will have to play a one pair hand out of position in a multiway pot, which is not too fun to do, and not too profitable either.....

You can limp the other pocket pairs 88 and lower in a loose fishy game.

As you become a stronger player, limping big suited connectors and suited aces becomes profitable, but they’ll only add to your variance and frustration if you play them as a novice.

And he's right. I limp in live games a lot because I can get away with it. Online, not so much. I wouldn't say that post needs updating since it's just a framework. You still have to come to your own conclusions. It's as comprehensive as you want to make it out to be.
