You need to understand that when you are severely short stacked you just can't make a big enough dint in their stack even if you win the pot. Hands to call or fold with:  Suited connectors KQs-76s, small pairs 66-44, suited aces or kings, and suited one-gappers (QTs, J9s, T8s, etc. If you have a pair greater than ten, and you take a deep breath, you might as well fold before the flop. There are so many aspects to consider to play winning PLO8.
