Erpel: Seems like a bad play unless you bet much more and that may not be good.

Overflow: Also pretty bad. Note with huge donks most of them dont put you on a range of hands, so they dont really care.

"Is the range we're representing by our action more or less important than the range we were representing leading up to our action?"

I think the answer to this question if I understand it correctly... is both are important (they really seem like the same thing).

If we are in a spot where we could only represent the nuts on the flop we will only be able to represent the nuts on the turn (Extreme example of why they seem like the same thing)
