See, overlimping is fine; I limp tons im omaha. The problem with limping here is that you expose your hand to the whole table with 4 players left to act. If you were in MP/CO, just calling would be fine. Playing this hand OOP isn't too great IMO unless the table is very loose/passive and you won't be facing many 3bets and you'll be able to ship your top sets. I don't like playing the flush draw OOP however with the multiway pot you are trying to induce. You want multiway pots with a hand like A2ssXX that have nut potential. This hand has almost no nut potential. You're going to see a 3-way flop at least, and probably 4-way or more because the sb will complete for such a good price with a marginal hand.

That said, if the players behind you are tight and will fold often, it's a good idea to flat here because you might often get one other caller behind you and you'll have position on 3 players postflop.

Setmining in omaha is also usually -EV with less than like ~200bbs FME.

We can argue about limping behind here and IMO it's table-dependent, but I can't say it's terrible. The limp/call is terrible. Once the pot is raised, you must lay this down.

I don't like checking because this is a flop that, once the first few players check, it will get checked through a lot; now that's not bad because this is a drawy semi-coordinated board so you often cause a lot of flushes/straights to hit and then you can win a nice pot. The problem with the check is that someone with a 5 has a plethora of outs. There are probably 2 or 3 pocket pairs out there as well so you are now giving out maybe as many as 14 outs! You have to be almost certain here that your opponents are total donks who will ship it with flushes and straights later on in the hand to give out that free card and even then I think it's close.

Even when you bet, though, you are in an ugly spot. You will get your money in against an opponent who either has you totally crushed or has 9 outs to a better full house. You don't even have redraw equity, except 2 outs for the QQ. But you need to get it in because your hand is just strong enough.
