Wow!!! This theory goes so deep!!! Xanadu, many thanks for taking the time to explain this. I won't pretend I fully understand it, but it does show that in a tourney/SnG environment, stack size does affect the decisions I should or shouldn't make, very insightful post!

So bottom line is, I need to be a little more selective about the frequency that I push any 2 when up against a player who probably understands the math in these situation!
