Hero. . . .

I am 4 tabling and don't have PT Omaha, so not really much of a read. I did note though that villain was on a decent number of the .25/.50 tables (I saw at least 4) so he seems to be a decent regular, the 2+2 type.

I am just learning PLO and am not particularly confident in my play, so I apologize if this is a standard spot. What's your play here?

If I bet and get raised, then what? How about if I check and he pots it?

Since he is multitabling he is more likely to be on autopilot than actually pay attention thus he rarely bluffs the turn with naked 67. And with your 4 outs to ~nuts and 9 outs to close to the nuts I dont mind check/calling and check/folding river. I expect him to check behind quite often though.
Betting is sorta bad because you are forced to put the rest in as a big dog if he shoves, or you are forced to fold your good draw vs his straight.

Who was this against?

...regardless, I think this is a bet here. I think flopped sets raise you most of the time on the flop and don't slowplay this flop. Only real hand I would worry about would be like 679X or quite possibly 6779 would only be the hands I would expect to lose to here. I think you lead this here for 10ish and if he raises, expect to be beat and do some math vs possible made hands. If he pots your bet, I think this a fold.
