Whenever there is a spot that comes up where I know I'm never bluffing it makes me feel uneasy and I think about how to add in bluffs. However, the following spot came up and many like it in big multiway pots where I can't see having a bluffing range being optimal even from a GT perspective given how strong ranges are multiway.

$10/$20 PLO Live FR; $6k Effective. Hero opens utg to $70 with Ah8h6dAc. 4 callers. Flop 4d5d7c. 

Flop I checked. Im so rarely able to bet this flop from EP, and there arent many good turns for me. MP villain bets pot. rest fold. Hero xc.

Turn As. Hero check, villain pots and I now c/r. I am certain its the optimal play given firstly, my line doesnt look that much like 86 to a rec player; also he can easily have 86 and I want to leverage my redraw.

However, I never have anything but 86+ here. Does that mean I shouldnt be raising vs very good opponents? Does it mean I should have some non 86+ hands? I think that spots come up in multiway PLO that people just have the nuts too often to be bluffing. How should we react in those spots then? I cant see delaying to river benefiting; it would just be delaying the same predicament.

If villain is overly stabby then yeah fine I can have a few c/r bluffs I suppose but if 4 people see the flop with wide ranges they will flop nutty hands too often.
