So I recently started reading "Pot Limit Omaha 8 Revealed" by Dan Deppen. In the chapter on preflop play, he says that you should rarely make a raise from UTG or UTG+1. He says that if you want to play a hand from these positions, you should tend to limp.

As a primarily NL player, this throws me off a bit. I've seen it mentioned several places that limping pre is an acceptable play in PLO8. My question is, when and how should we go about implementing this?

It obviously seems super exploitable to only limp marginal hands from EP, and raise with our strong holdings. Should we be limping 100% of our range from these positions? Should we have a limp/re-raise range? How frequently do we need to limp strong holdings from EP to maintain some sort of balance with our EP limps?

Also, when we do limp, how often should we be continuing facing a raise behind us?

I'm basically just looking for advice on how to reasonably implement a limping strategy in PLO8. Thanks!

It was probably written way before everything became 6 max. Even 8/9 max you should be raising most of you range. There may be some hands that are better to limp if your stack size cannot face a 3 bet and there are ICM factors but that's about it. Some would say shouldn't be limping any of your opening range in EP.

That's understandable. It's the case in Omaha as well - limping is much more "OK" in Omaha than in NLHE because of multiple factors: (1) having "initiative" isn't nearly as important as in hold'em (because hands aren't as black and white), (2) you have far less fold equity - flops are seen a far higher percentage of the time, and (3) it's not as exploitable, because preflop hand ranges are generally much wider than in NL and more pots are going to be multiway anyway.

You have to be careful in PLO8 vs. PLO with #3, because it's arguably easier to "categorize" a limping hand range in O8 (e.g. "this guys openlimps high hands and bad A2/A3 hands").

A good exercise with this is to really think about WHY you raise preflop in NLHE. You'll find that the effects of all the reasons are far less pronounced in Omaha games.

Table dynamics should be your largest consideration. Consider this: you're at a very loose and very passive table. You have no fold equity preflop, so you'll constantly be out of position when you play hands in MP and EP. But your limps will go through. In this scenario, I would raise with strong hands for value, and consider limping (even open-limping) with hands that are long-shot nutty, along the lines of A5TT suited to the ace.

It's difficult to be "super exploitable" preflop in Omaha compared to Hold'em. Don't overestimate that. You could certainly have a wide variety of A2, BBBB, and AA hands in your limp range in EP in certain tables. Whether it's correct or not to raise or limp re-raise with these hands is going to heavily depend on the table. There are some tables where I don't have a limp range (tighter games), some where I have a wide limp range (loose/passive tables), and some where I have a limp-reraise range (usually targeting specific aggressive players).

Strong majority of the time.

If you raise from early position you provide the players in position more ammunition to fire at you.

Agree with most of what DMoogle is saying. I find myself in general being a player that tends to check/check raise a lot, and maybe that's why Omaha has struck such a cord with me. Either way, I think a case can be made for the open limp in a lot of situations where you don't necessarily want to isolate but want to see flops, aka 9TJQ etc. I find a huge portion of my play style involves limping, especially in early position, to the point that I dark check flops live when first to act (maybe a fault but I like having the open action on them many times).
