OR is a good reg.
SB is a nit
bb no stats
I fold here because I think the nit hold a high % the A high flush, set+A 
or the naked A who wants to doble barrell in a bad spot to do this (unless the bb is a reg). Another point is that he bet 80% of the pot with 3 villain behind, I think if he holds Qhxh or Jhxh he might bet small or check call if I bet (trying to steal the pot). The problem here is that I can´t call turn and river profitably if he decide to doble barrell with him entire range, but the fold could be weak anyway.
Sorry if I can´t explain my point of view
