No point risking the whole stack if your just going to face a hand that either folds or is willing to go all in. .

This is exactly the type of situation where push/fold makes sense. raising 3-4bb into the big stack when you have 20bb left is going to get you in a lot of trouble when he goes over the top of you (gap concept). You want to push a lot of hands and hopefully pick up blinds and antes. If opponent calls too wide then you are likely to double up and if opponent is too tight then you are going to steal a lot of blinds and antes. Unexploitable push fold strategies can be calculated for short effective stack sizes <20BB so that if your opponent calls a with range of hands that is not unexploitable then you are exploiting him.

In the situation you describe both players are effectively short stacks. The big stack plays the right strategy of call/fold and presumably push fold as well, but the shorty raising 3-4bb would not work out well.

This situation would arise in a super turbo HUSNG I think and yep you're right that for moderate to deep stack sizes it is irrelevant but when you are forced to play as a short stack or finish off a short stack then I think it is essential to know about unexploitable strategies.
