Preflop is fine but flop is 100% a check - will almost never get a fold in a 3 way pot on this board unless they are playing incredibly loose preflop and you can be pretty happy to continue on any diamond, a J and a T (and sometimes you'll have live 2 pair outs also) - by betting flop you are basically just throwing away alot of equity and in this case equity to the nuts which is especially bad. You need to be very careful in PLO about bet/folding significant equity - isn't near as big a deal in hold em as it is so rare that you have the 30-50% equity on flop and turn like you so often do with PLO. For the same reason i'd check behind the naked nut flush draw and 2nd/3rd nut flush draw here - little to no fold equity and it has too little equity to get it in when villain pots it and you NEVER want to be in the situatino where you ahve to bet fold 35% equity to the nuts or even near nuts (and again same logic would dictate that checking behind the 7th nut flush draw is far less important as you don't mind bet/folding a naked baby flush draw as much as you will suffer from reverse implied odds given that when you hit you only have a bluff catcher rather than a clear value bet and thus it isn't worth near as much.
I liked PLO better an hour ago when I was still running goot.
Okay, so quick thought here. When we call a bet/raise on the turn out of position with a strong draw, and you hit the river, should you be donk-betting pretty often, since villains will check back worse hands most of the time (probably)?
An example:

Hand converted by PokerTracker 3
Hero (SB): $2.12
