How often are we good with two pairs in omaha, or with a set on the river

Well I think only correct answer here is classical "it depends". How likely is it that villains hold those straights or better? E.g. if board is K♦:9♣:3♥:4♥:6♥: its still pretty hard for opponent to show up with 25xx or 75xx if he has called flop and turn bets. But backdoor flush is lot more likely possibility. Could be lot of QJ9x, Kxxx with hearts. In general we should give lot more weight for backdoor possibilities on omaha compared to holdem. One thing I have learned when not giving backdoors enough weight and value betting or calling too wide. We might be able to limit hand range depending of preflop action but I think this is quite limited in fishy games. In a way that people might be calling with hands that should be snap fold etc.

If flop offer oesd or wrap possibilities and those complete it can often be spot where two pair or set are weak holdings and more or less bluff catchers. If they dont block straight likely bad bluff catchers. In some other spots with busted draws top two pair can be very strong. Also stack to pot ratio (SPR) is extremely important. In single raised pot two pair with no support can be mediocre or weak hand. E.g. lets say flop is T♥:9♥:5♦: and you have AAT9 no hearts. Two pair but you dont want to see K, Q, J, 8, 7, 6 or heart. So if you cbet and get raised or there is just other heavy action it might be best to just fold. But if we have 3bet and SPR is lower top two pairs can be clear stack off hand. Also in 3bet pots dry AAxx can be stack off in some J54 flop but in single raised pot it would be pretty crazy.

Hi stevegold87,
I can't answer your question, but check out Equilab Omaha
If you're familiar with the Hold'em version of Equilab, you should bet the hang of it pretty quickly.

The really, really hard part (for me) is putting opponents on a range.

I do find it very hard to put people on a range in Omaha, they seem to be called with any two cardsa lot of times which I why I find this game tough but very lucrative..sometimes....

Yeah -- this is primarily a post-flop game, and although you need to be aware of hand strength pre-flop, you need to be super-aware post-flop of:
 board texture in relation to our hand
 blockers
 re-draws -- by that I mean a made straight is nice, but a made straight with a re-draw to a flush is nicer etc
 sets are trap hands
 etc
 etc

lol nice

In PLO there are situations where 2 pairs is an easy fold, sometimes it's an easy shove. Sometimes you bet for value and sometimes you bluff catch with a call.

As Vorpal said, it depends.
