I have seen this concept referenced on a several occasions but I don't think I understand it. There are a few HH posts where people have said they will check their whole range in a spot or bet it (instead of playing a mixed strategy). How do you figure out if you should be betting or checking your whole range in a spot? Is there a science to it? As I am not sure that arbitrarily deciding "hmm, this looks like a good spot to bet or check with my whole range" is the correct approach.
