Crash course in PLO needed

[BriMc]

I only play live. There just aren't enough strong players in the games I play to give me that many bluffing opportunites.

To give you an idea of what I'm talking about, in my last Omaha session, I floped undertrips, UTG bet out pot, MP called, I pushed, UTG folded his OESD, and MP called for 1200 dollars with an OESFD.

UTG always slowplays his big made hands and bets his draws.
MP always calls with draws and raises with made hands.

When am I ever going to bluff this guy?

There are about 2-3 regs in these games I can bluff, and one weak tighty I can push off of everything but the stone cold nuts. I've pushed him off the 2nd and 3rd nuts with nothing at lease 5 times in the last month and he still won't call.
