Let's say this is OFC pineapple HU.

When you are dealt two pairs in the opening 5 cards and you are out of position, is it always correct to place both pairs on the bottom? What about if you in position and both pairs are live? What if the lower pair is not live? Do we place the "Dead-er" low pair in the middle? What if the higher pair is not live, or also "Dead-er"? Sorry for my lack of terminology.
